Sunscreen myths, controversies continue
, according to Steven Q. Wang, MD, director of dermatologic surgery and dermatology, Memorial Sloan-Kettering Cancer Center, Basking Ridge, N.J.
Although sunscreens are regulated as an OTC drug under the Food and Drug Administration, concerns persist about the safety of sunscreen active ingredients, including avobenzone, oxybenzone, and octocrylene, Dr. Wang said in a virtual presentation at MedscapeLive’s annual Las Vegas Dermatology Seminar.
In 2019, the FDA proposed a rule that requested additional information on sunscreen ingredients. In response, researchers examined six active ingredients used in sunscreen products. The preliminary results were published in JAMA Dermatology in 2019, with a follow-up study published in 2020 . The studies examined the effect of sunscreen application on plasma concentration as a sign of absorption of sunscreen active ingredients.
High absorption
Overall, the maximum level of blood concentration went above the 0.5 ng/mL threshold for waiving nonclinical toxicology studies for all six ingredients. However, the studies had several key limitations, Dr. Wang pointed out. “The maximum usage condition applied in these studies was unrealistic,” he said. “Most people when they use a sunscreen don’t reapply and don’t use enough,” he said.
Also, just because an ingredient is absorbed into the bloodstream does not mean it is toxic or harmful to humans, he said. Sunscreens have been used for 5 or 6 decades with almost zero reports of systemic toxicity, he observed.
The conclusions from the studies were that the FDA wanted additional research, but “they do not indicate that individuals should refrain from using sunscreen as a way to protect themselves from skin cancer,” Dr. Wang emphasized.
Congress passed the CARES Act in March 2020 to provide financial relief for individuals affected by the novel coronavirus, COVID-19. “Within that act, there is a provision to reform modernized U.S. regulatory framework on OTC drug reviews,” which will add confusion to the development of a comprehensive monograph about sunscreen because the regulatory process will change, he said.
In the meantime, confusion will likely increase among patients, who may, among other strategies, attempt to make their own sunscreen products at home, as evidenced by videos of individuals making their own products that have had thousands of views, said Dr. Wang. However, these products have no UV protection, he said.
For current sunscreen products, manufacturers are likely to focus on titanium dioxide and zinc oxide products, which fall into the GRASE I category for active ingredients recognized as safe and effective. More research is needed on homosalate, avobenzone, octisalate, and octocrylene, which are currently in the GRASE III category, meaning the data are insufficient to make statements about safety, he said.
Vitamin D concerns
Another sunscreen concern is that use will block healthy vitamin D production, Dr. Wang said. Vitamin D enters the body in two ways, either through food or through the skin, and the latter requires UVB exposure, he explained. “If you started using a sunscreen with SPF 15 that blocks 93% of UVB, you can essentially shut down vitamin D production in the skin,” but that is in the laboratory setting, he said. What happens in reality is different, as people use much less than in a lab setting, and many people put on a small amount of sunscreen and then spend more time in the sun, thereby increasing exposure, Dr. Wang noted.
For example, a study published in 1988 showed that long-term sunscreen users had levels of vitamin D that were less than 50% of those seen in non–sunscreen users. However, another study published in 1995 showed that serum vitamin D levels were not significantly different between users of an SPF 17 sunscreen and a placebo over a 7-month period.
Is a higher SPF better?
Many patients believe that the difference between a sunscreen with an SPF of 30 and 60 is negligible. “People generally say that SPF 30 blocks 96.7% of UVB and SPF 60 blocks 98.3%, but that’s the wrong way of looking at it,” said Dr. Wang. Instead, consider “how much of the UV ray is able to pass through the sunscreen and reach your skin and do damage,” he said. If a product with SPF 30 allows a transmission of 3.3% and a product with SPF 60 allows a transmission of 1.7%, “the SPF 60 product has 194% better protection in preventing the UV reaching the skin,” he said.
Over a lifetime, individuals will build up more UV damage with consistent use of SPF 30, compared with SPF 60 products, so this myth is important to dispel, Dr. Wang emphasized. “It is the transmission we should focus on, not the blockage,” he said.
Also, consider that the inactive ingredients matter in sunscreens, such as water resistance and film-forming technology that helps promote full coverage, Dr. Wang said, but don’t discount features such as texture, aesthetics, smell, and color, all of which impact compliance.
“Sunscreen is very personal, and people do not want to use a product just because of the SPF value, they want to use a product based on how it makes them feel,” he said.
At the end of the day, “the best sunscreen is the one a patient will use regularly and actually enjoy using,” Dr. Wang concluded.
Dr. Wang had no relevant financial conflicts to disclose.

Immunotherapy could fill unmet need in leptomeningeal metastases
Results from the trial were reported at the Society for Immunotherapy of Cancer’s 35th Anniversary Annual Meeting.
“Unfortunately, when patients present with leptomeningeal disease, they usually have a poor prognosis. Their median survival is measured at 6-24 weeks,” commented lead study author Jarushka Naidoo, MBBCh, an adjunct assistant professor of oncology at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins University, Baltimore, and a consultant medical oncologist at Beaumont Hospital in Dublin.
“While there may be some standard approaches for how we treat leptomeningeal disease, there are no universal standard therapies that are efficacious across solid tumor types,” Dr. Naidoo added.
With this in mind, Dr. Naidoo and colleagues tested systemic pembrolizumab in a trial of patients with leptomeningeal metastases from solid tumors.
The trial closed early because of poor accrual, after enrolling 13 patients: 5 with breast carcinoma, 3 with high-grade glioma, 3 with non–small cell lung cancer, 1 with squamous cell carcinoma of the skin, and 1 with head and neck squamous carcinoma. Nine patients (69%) had received at least two prior lines of systemic therapy.
Response, safety, and biomarkers
Overall, five patients (38%) had a central nervous system response, as ascertained from radiologic response on MRI, cytologic response in cerebrospinal fluid (CSF), and/or clinical response in neurologic symptoms, Dr. Naidoo reported.
Two patients had a complete CNS response: a patient with squamous cell carcinoma of the skin, who was still alive at 3 years, and a patient with non–small cell lung cancer, who survived 9 months but succumbed to metastases elsewhere.
For the entire cohort, median CNS progression-free survival was 2.9 months, and median overall survival was 4.9 months.
“This is consistent with published prospective studies of systemic agents for leptomeningeal disease,” Dr. Naidoo pointed out. “Notably, even though numbers are small, we do see the tail-on-the-curve phenomenon in both of these survival curves, which is consistent with immune checkpoint blockade prospective studies.”
The rate of grade 3 or higher treatment-related adverse events was 15.4%, and there were no grade 3 or higher immune-related adverse events.
The number of patients was too small for formal correlational testing, but both patients who achieved a complete response developed immune-related adverse events.
The trial’s biomarker analyses showed that an aneuploidy assay using CSF tumor-derived DNA performed well at detecting leptomeningeal metastases, with sensitivity of 84.6%, compared with just 53.8% for CSF cytopathology (the current preferred method).
A multiplex assay of CSF cytokines identified similar baseline profiles for patients who went on to have responses and showed similar changes in profile (notably a reduction in proinflammatory cytokines) for the two patients who had complete responses.
Given the trial’s 38% CNS response rate, pembrolizumab “needs to be studied in larger populations of patients to confirm this result, but it could be used as a potential treatment option for patients with leptomeningeal disease from solid tumors,” Dr. Naidoo concluded. “Reassuringly, pembrolizumab was well tolerated, and this is extremely important in a patient population that is traditionally quite frail and in which other standard therapies that are used, such as high-dose methotrexate or intrathecal chemotherapy, are associated with far higher rates of toxicity.”
An unmet need
“Leptomeningeal metastasis is a strong unmet need, although its occurrence is fortunately quite rare,” commented Kim Margolin, MD, a clinical professor and medical oncologist at City of Hope National Medical Center in Duarte, Calif., who was not involved in this study.
The trial is noteworthy for showing activity of programmed death–1 (PD-1) blockade given only systemically and not with additional intrathecal therapy (as has been done in a concurrent study at MD Anderson Cancer Center) and for providing insight into various biomarkers, Dr. Margolin said in an interview.
“I cannot take a stand on author conclusions other than to agree it warrants further evaluation in carefully selected patients, and it would be great to compare something like peripheral PD-1 blockade alone versus in combination with intrathecal therapy versus a combination such as CTLA4 blockade plus PD-1 blockade such as our group and others have shown to have increased activity in CNS metastases over PD-1 block alone,” Dr. Margolin said.
“The drugs in this class are already approved, so there is no reason not to try them,” she noted.
However, patients with leptomeningeal metastases of melanoma, for example, are likely to have already received anti-PD-1 immunotherapy.
“So the settings in which off-the-shelf PD-1 blockade would be useful are extremely limited,” she concluded.
The current trial was funded by Merck, the National Institutes of Health, the Lung Cancer Foundation of America, the International Association for the Study of Lung Cancer, and Johns Hopkins University Seed Grants. Dr. Naidoo disclosed relationships with AstraZeneca, Merck, Bristol Myers Squibb, and Roche/Genentech. Dr. Margolin disclosed no relevant conflicts of interest.

Expert shares key facts about keloid therapy
although few understand what this process entails, according to Hilary E. Baldwin, MD, of Rutgers Robert Wood Johnson Medical School, New Brunswick, N.J.
A key point to keep in mind about keloids is that, while they result from trauma, however slight, trauma alone does not cause them, Dr. Baldwin said in a presentation at the virtual MedscapeLive’s annual Las Vegas Dermatology Seminar.
In general, people with darker skin form keloids more easily and consistently than those with lighter skin, but keloids in people with darker skin are often easier to treat, Dr. Baldwin added. Also worth noting is the fact that earlobe keloids recur less frequently, she said.
Most patients with keloids are not surgical candidates, and they need convincing to pursue alternative options, Dr. Baldwin said.
However, successful management of keloids starts with sorting out what the patient wants. Some want “eradication with normal skin,” which is not realistic, versus simply flattening, lightening, or eradication of the keloid and leaving a scar, she noted. “That skin is never going to look normal,” she said. “Very often, they don’t need the whole thing gone, they just want to be better, and not itch or cause them to think about it all the time.”
Quality clinical research on the management of keloids is limited, Dr. Baldwin continued. “If you are holding out for a good randomized, placebo-controlled, double-blind study with a healthy ‘N,’ adequate follow-up rational conclusions, don’t hold your breath,” she said. The few literature reviews on keloids in recent decades concluded that modalities used to treat keloids are based on anecdotal evidence rather than rigorous research, she noted.
Size (and shape) matters
The decision to cut a keloid depends on several factors, including lesion size, shape, age, and location, but especially patient commitment to follow up and postsurgery care, said Dr. Baldwin.
She noted that larger keloids are no more difficult to remove than smaller ones, and patients tend to be more satisfied with the outcome with larger keloids. In terms of shape, pedunculated lesions are most amenable to surgery because of their small footprint. “Often the base does not contain keloidal tissue, and the patient gets the maximum benefit for the least risk,” she said. In addition, the residue from the removal of large keloids is often more acceptable.
Options for adjunctive therapy when excising keloids include corticosteroids, radiation, interferon, pressure dressings, dextran hydrogel scaffolding, and possibly botulinum toxin A, Dr. Baldwin said.
Adjunctive treatment alternatives
Intralesional corticosteroids can prevent the recurrence of keloids, and Dr. Baldwin recommends a 40 mg/cc injection into the base and walls of the excision site immediately postop, with repeat injections every 2 weeks for 2 months regardless of the patient’s clinical appearance. However, appearance determines the dose and concentration during 6 months of monthly follow-up, she said.
Radiation therapy, while not an effective monotherapy for keloids, can be used as an adjunct. A short radiation treatment plan may improve compliance, and no local malignancies linked to radiation therapy for keloids have been reported, she said. Dr. Baldwin also shared details of using an in-office superficial radiation therapy with the SRT-100 device, which she said has shown some ability to reduce recurrence of keloids.
Interferon, which can reduce production of collagen and increase collagenase can be used in an amount of 1.5 million units per linear cm around the base and walls of a keloid excision (maximum is 5 million units a day). Be aware that patients can develop flulike symptoms within a day or so, and warn patients to take it easy and monitor for symptoms, she said.
Studies of imiquimod for keloid recurrence have yielded mixed results, and a 2020 literature review concluded that it is not recommended as a treatment option for keloids, said Dr. Baldwin. Pressure dressings also have not shown effectiveness on existing lesions.
Botulinum toxin A has been studied as a way to prevent hypertrophic scars and keloids and potentially for preventing recurrence by injecting at the wound edges, she said. A meta-analysis showed that botulinum toxin was superior to corticosteroids for treating keloids, but “there were a lot of problems with the studies,” she said.
One other option for postexcision keloid treatment is dextran hydrogel scaffolding, which involves a triple-stranded collagen denatured by heat, with the addition of dextran to form a scaffold for fibroblasts, Dr. Baldwin said. This product, when injected prior to the final closure of surgical excision of keloids, may improve outcomes in certain areas, such as the earlobe, she said.
Dr. Baldwin concluded with comments about preventing other keloids from getting out of hand, which is extraordinarily challenging. However, treatment with dupilumab might provide an answer, although data are limited and more research is needed. She cited a case study of a male patient who had severe atopic dermatitis, with two keloids that improved after 7 months on dupilumab. The Th2 cytokines interleukin (IL)–4 and IL-13 have been implicated as key mediators in the pathogenesis of fibroproliferative disorders, which may respond to dupilumab, which targets Th2, she noted.
Dr. Baldwin had no relevant financial conflicts to disclose.

although few understand what this process entails, according to Hilary E. Baldwin, MD, of Rutgers Robert Wood Johnson Medical School, New Brunswick, N.J.
A key point to keep in mind about keloids is that, while they result from trauma, however slight, trauma alone does not cause them, Dr. Baldwin said in a presentation at the virtual MedscapeLive’s annual Las Vegas Dermatology Seminar.
In general, people with darker skin form keloids more easily and consistently than those with lighter skin, but keloids in people with darker skin are often easier to treat, Dr. Baldwin added. Also worth noting is the fact that earlobe keloids recur less frequently, she said.
Most patients with keloids are not surgical candidates, and they need convincing to pursue alternative options, Dr. Baldwin said.
However, successful management of keloids starts with sorting out what the patient wants. Some want “eradication with normal skin,” which is not realistic, versus simply flattening, lightening, or eradication of the keloid and leaving a scar, she noted. “That skin is never going to look normal,” she said. “Very often, they don’t need the whole thing gone, they just want to be better, and not itch or cause them to think about it all the time.”
Quality clinical research on the management of keloids is limited, Dr. Baldwin continued. “If you are holding out for a good randomized, placebo-controlled, double-blind study with a healthy ‘N,’ adequate follow-up rational conclusions, don’t hold your breath,” she said. The few literature reviews on keloids in recent decades concluded that modalities used to treat keloids are based on anecdotal evidence rather than rigorous research, she noted.
Size (and shape) matters
The decision to cut a keloid depends on several factors, including lesion size, shape, age, and location, but especially patient commitment to follow up and postsurgery care, said Dr. Baldwin.
She noted that larger keloids are no more difficult to remove than smaller ones, and patients tend to be more satisfied with the outcome with larger keloids. In terms of shape, pedunculated lesions are most amenable to surgery because of their small footprint. “Often the base does not contain keloidal tissue, and the patient gets the maximum benefit for the least risk,” she said. In addition, the residue from the removal of large keloids is often more acceptable.
Options for adjunctive therapy when excising keloids include corticosteroids, radiation, interferon, pressure dressings, dextran hydrogel scaffolding, and possibly botulinum toxin A, Dr. Baldwin said.
Adjunctive treatment alternatives
Intralesional corticosteroids can prevent the recurrence of keloids, and Dr. Baldwin recommends a 40 mg/cc injection into the base and walls of the excision site immediately postop, with repeat injections every 2 weeks for 2 months regardless of the patient’s clinical appearance. However, appearance determines the dose and concentration during 6 months of monthly follow-up, she said.
Radiation therapy, while not an effective monotherapy for keloids, can be used as an adjunct. A short radiation treatment plan may improve compliance, and no local malignancies linked to radiation therapy for keloids have been reported, she said. Dr. Baldwin also shared details of using an in-office superficial radiation therapy with the SRT-100 device, which she said has shown some ability to reduce recurrence of keloids.
Interferon, which can reduce production of collagen and increase collagenase can be used in an amount of 1.5 million units per linear cm around the base and walls of a keloid excision (maximum is 5 million units a day). Be aware that patients can develop flulike symptoms within a day or so, and warn patients to take it easy and monitor for symptoms, she said.

Aspirin and statins in chronic hepatitis B: It’s complicated
For patients with chronic hepatitis B, the protective effects of aspirin against hepatocellular carcinoma (HCC) can vary with cirrhosis status and statin treatment, a pair of new studies finds.
One study showed that, although aspirin is linked to a reduction in risk for HCC in these patients, comedication with statins could explain some of that effect. The other showed that cirrhosis dampens the risk-reduction benefit of aspirin.
Currently, there is a link between a reduction in HCC risk and aspirin or statins in patients with chronic hepatitis B, said investigator Won-Mook Choi, MD, PhD, from the University of Ulsan College of Medicine, in Seoul, Republic of Korea.
In one of their analyses, Choi and his colleagues teased out the contribution of each drug and found that the decrease in HCC risk conferred by statins is similar whether or not patients also take aspirin.
“Only statins showed consistent and significant dose-dependent reductions in the risk of HCC, regardless of study design,” said Choi, who presented the findings at The Liver Meeting 2020.
The second study, which looked at the association between aspirin and the risk for HCC in patients with and without cirrhosis, was presented by Heejoon Jang, MD, from the Seoul National University College of Medicine.
Aspirin was shown to be associated with a reduced risk for HCC, but cirrhosis “had a substantial effect on this association,” erasing the benefit of aspirin, Jang reported.
Statins and aspirin
Statins and aspirin are more likely to be prescribed together for patients with chronic hepatitis B but no cirrhosis, said Choi. For that reason, he and his colleagues analyzed data from the Korean National Health Insurance Service database from 2005 to 2015.
In their nested case-control analysis, 17,150 patients with HCC were matched for sex, age, and other factors to 817,675 patients without HCC. All participants had chronic hepatitis B without cirrhosis and had never received antiviral treatment.
The team also analyzed the incidence of HCC in two historic cohorts of patients with chronic hepatitis B but no cirrhosis, one consisting of 673,107 people who took aspirin and the other with 588,045 who took statins.
The nested case-control analysis showed an 11% risk reduction with aspirin use (adjusted odds ratio [OR], 0.89; 95% CI, 0.85 - 0.94) and a 61% risk reduction with statin use (adjusted OR, 0.39; 95% CI, 0.36 - 0.40). There was a dose-response effect with statins, but not with aspirin.
The historic cohort analysis showed a 33% reduction in the risk for HCC with aspirin (adjusted hazard ratio [HR], 0.67; 95% CI, 0.63 - 0.72) and a 67% reduction with statins (adjusted HR, 0.33; 95% CI, 0.30 - 0.37). However, stratified analyses by drug showed a statin benefit with or without aspirin (P < .001 for both), but no aspirin benefit without statins.
Cirrhosis and aspirin
To assess the interaction between cirrhosis and aspirin, Jang and his colleagues identified 329,635 patients with chronic hepatitis B in the Korean National Health Insurance Service database.
A total of 20,200 had taken aspirin for at least 90 consecutive days, and the rest had never received antiplatelet therapy. Treated and untreated patients were matched for several factors, and HCC incidence was assessed after a median follow-up of 6.7 years.
Among the 2,697 patients who developed HCC during follow-up, the cumulative incidence of HCC was significantly lower for those who took aspirin than for those who did not (P < .001). There was a 15% reduction in the risk for HCC in the aspirin group (adjusted HR, 0.85; 95% CI, 0.78 - 0.92).
However, in patients with cirrhosis, the benefit of aspirin disappeared. Patients without cirrhosis still had a 13% reduction in risk for HCC (adjusted HR, 0.87: 95% CI, 0.79 - 0.95). This group also had a slightly elevated risk for major bleeding (adjusted HR, 1.1; 95% CI, 1.03 - 1.28).
The findings from these two studies add to a growing body of literature that shows the promise of statins and aspirin, which are both readily available and relatively safe, said Amit Singal, MD, from the UT Southwestern Medical Center in Dallas, who was not involved with either study.
“The studies are relatively simple but really do tackle an area of immense need in the field,” he said. Short of having higher-quality data, however, statins and aspirin aren’t quite ready to become bespoke chemotherapies in the clinic, he added, although the results show promise for future randomized trials.
The subgroup analyses that looked at cirrhosis and the interplay of aspirin and statins can help with the planning of such trials, which “is really important for trial design,” Singal noted.
He also pointed to studies that, unlike these results, have found a benefit of aspirin in patients with cirrhosis, underscoring the need for randomized trials. However, “each study does provide a data point that can help to inform those trials,” he said.
Choi and Jang have disclosed no relevant financial relationships. Singal is a consultant for Genentech, Bayer, Eisai, Exelixis, Bristol-Myers Squibb, Roche, Glycotest, FujiFilm, GRAIL, and Exact Sciences, primarily in relation to HCC treatment and screening, not chemoprevention.

Pronounced racial differences in HBsAg loss after stopping nucleos(t)ide
Loss of the hepatitis B surface antigen (HBsAg), a marker for functional cure of hepatitis B infection, is nearly six times more common among White patients than Asian patients following cessation of therapy with a nucleotide or nucleoside analogue, investigators in the RETRACT-B study group report.
Among 1,541 patients in a global retrospective cohort, the cumulative rate of HBsAg loss 4 years after cessation of therapy with entecavir (ETV), tenofovir disoproxil fumarate (TDF), or other nucleoside/nucleotide analogue (“nuc” or NA) was 11% in Asian patients, compared with 41% in Whites, which translated in multivariate analysis into a hazard ratio (HR) of 5.8 (P < .001), said Grishma Hirode, a clinical research associate and PhD candidate at the Toronto Centre for Liver Disease.
“On univariate Cox regression, the rate of S [antigen] loss was significantly higher among older patients, among [Whites], and among tenofovir-treated patients prior to stopping,” she said during the virtual annual meeting of the American Association for the Study of Liver Diseases.
Although NAs are effective at suppressing hepatitis B viral activity, functional cure as indicated by HBsAg loss is uncommon, Ms. Hirode noted.
“Finite use of antiviral therapy has been proposed as an alternative to long-term therapy, and the rationale for stopping nuc therapy is to induce a durable virologic remission in the form of an inactive carrier state, and ideally a functional cure,” she said.
The RETRACT-B (Response after End of Treatment with Antivirals in Chronic Hepatitis B) study group, comprising liver treatment centers in Canada, Europe, Hong Kong, and Taiwan, studies outcomes following cessation of nucleos(t)ide analogue therapy.
The investigators looked at data on 1,541 patients, including those with both hepatitis B e-antigen (HBeAg) positive and HBeAg-negative disease at the start of therapy, all of whom were HBeAg negative at the time of antiviral cessation and had undetectable serum HBV DNA. Patients with hepatitis C, hepatitis D and/or HIV co-infection were excluded, as were patients who had received interferon treatment less than 12 months before stopping.
The mean age at baseline was 53 years. Men comprised 73% of the sample. In all, 88% of patients were Asian, 10% White, and 2% other.
In patients for whom genotype data was known, 0.5% had type A, 43% type B, 11% type C, and 2% type D.
Nearly two-thirds of patients (60%) were on ETV at the time of drug cessation, 29% were on TDF, and 11% were on other agents.
In all, 5% of patients had cirrhosis at the time of nucleos(t)ide cessation, the mean HBsAg was 2.6 log10 IU/mL, and the mean alanine aminotransferase (ALT) level was 0.6 times the upper limit of normal.
The median duration of NA therapy was 3 years.
The cumulative rates of HBsAg loss over time among all patients was 3% at 1 year, 8% at 2 years. 12% at 3 years, and 14% at 4 years. Cumulative rates of antigen loss at year 4 were significantly greater for patients 50 and older vs. those younger than 50 (18% vs. 9%, respectively, P = .01), Whites vs. Asians (41% vs. 11%, P < .001), and in those who had been on TDF vs. ETV (17% vs. 12%, P = .001). There was no significant difference in cumulative HBsAg loss between patients who were HBeAg positive or negative at the start of NA therapy.
Cumulative rates of retreatment were 30% at 1 year, 43% at 2 years, 50% at 3 years, and 56% at 4 years. The only significant predictor for retreatment was age, with patients 50 and older being significantly more likely to be retreated by year 4 (63% vs. 45%, respectively, P < .001).
In a univariate model for HBsAg loss, the HR for age 50 and older was 1.7 (P = .01), the HR for White vs. Asian patients was 5.5 (P < .001), and the HR for TDF vs. ETV was 2.0 (P = .001).
A univariate model for retreatment showed an HR of 1.6 for patients 50 and older; all other parameters (sex, race, NA type, and HBeAg status at start of therapy) were not significantly different.
In multivariate models, only race/ethnicity remained significant as a predictor for HBsAg loss, with a HR of 5.8 for Whites vs. Asians (P < .001), and only age 50 and older remained significant as a predictor for retreatment, with a HR of 1.6 (P < .001).
The 4-year cumulative rate of virologic relapse, defined as an HBV DNA of 2000 IU/mL or higher) was 74%, the rate of combined DNA plus ALT relapse (ALT 2 or more times the upper limit of normal) was 56%, and the rate of ALT flares (5 or more times the upper limit of normal) was 33%.
In all, 15 patients (1%) experienced hepatic decompensation, and 12 (0.96%) died, with 9 of the deaths reported as liver-related.
Race/ethnicity differences previously seen
Liver specialist Anna Suk-Fong Lok, MD, professor of medicine at the University of Michigan in Ann Arbor, who was not involved in the study, said that the findings are not especially surprising.
“When the studies came out from Asian countries showing that patients who were taken off treatment had a higher rate of S antigen loss than patients who stayed on treatment, the rate of S antigen loss was not all that impressive, but when you look at the European studies the rate of S antigen loss was very high,” she said in an interview.
“The question of course is ‘Why?’ I don’t think we understand completely why. We can speculate, but none of these type studies give us a definitive answer,” she said.
Possible reasons for the racial differences in HBsAg loss include differences in hepatitis B genotype, she said.
“Another possibility is that Asian patients may have been infected either at the time of birth or as a young kid, so they may have been infected for a much longer period of time than [Whites], who usually acquire infections as adults,” Dr. Lok said.
There may also be differences between patient populations in immune responses following cessation of antiviral therapy, she added.

Loss of the hepatitis B surface antigen (HBsAg), a marker for functional cure of hepatitis B infection, is nearly six times more common among White patients than Asian patients following cessation of therapy with a nucleotide or nucleoside analogue, investigators in the RETRACT-B study group report.
Among 1,541 patients in a global retrospective cohort, the cumulative rate of HBsAg loss 4 years after cessation of therapy with entecavir (ETV), tenofovir disoproxil fumarate (TDF), or other nucleoside/nucleotide analogue (“nuc” or NA) was 11% in Asian patients, compared with 41% in Whites, which translated in multivariate analysis into a hazard ratio (HR) of 5.8 (P < .001), said Grishma Hirode, a clinical research associate and PhD candidate at the Toronto Centre for Liver Disease.
“On univariate Cox regression, the rate of S [antigen] loss was significantly higher among older patients, among [Whites], and among tenofovir-treated patients prior to stopping,” she said during the virtual annual meeting of the American Association for the Study of Liver Diseases.
Although NAs are effective at suppressing hepatitis B viral activity, functional cure as indicated by HBsAg loss is uncommon, Ms. Hirode noted.
“Finite use of antiviral therapy has been proposed as an alternative to long-term therapy, and the rationale for stopping nuc therapy is to induce a durable virologic remission in the form of an inactive carrier state, and ideally a functional cure,” she said.
The RETRACT-B (Response after End of Treatment with Antivirals in Chronic Hepatitis B) study group, comprising liver treatment centers in Canada, Europe, Hong Kong, and Taiwan, studies outcomes following cessation of nucleos(t)ide analogue therapy.
The investigators looked at data on 1,541 patients, including those with both hepatitis B e-antigen (HBeAg) positive and HBeAg-negative disease at the start of therapy, all of whom were HBeAg negative at the time of antiviral cessation and had undetectable serum HBV DNA. Patients with hepatitis C, hepatitis D and/or HIV co-infection were excluded, as were patients who had received interferon treatment less than 12 months before stopping.
The mean age at baseline was 53 years. Men comprised 73% of the sample. In all, 88% of patients were Asian, 10% White, and 2% other.
In patients for whom genotype data was known, 0.5% had type A, 43% type B, 11% type C, and 2% type D.
Nearly two-thirds of patients (60%) were on ETV at the time of drug cessation, 29% were on TDF, and 11% were on other agents.
In all, 5% of patients had cirrhosis at the time of nucleos(t)ide cessation, the mean HBsAg was 2.6 log10 IU/mL, and the mean alanine aminotransferase (ALT) level was 0.6 times the upper limit of normal.
The median duration of NA therapy was 3 years.
The cumulative rates of HBsAg loss over time among all patients was 3% at 1 year, 8% at 2 years. 12% at 3 years, and 14% at 4 years. Cumulative rates of antigen loss at year 4 were significantly greater for patients 50 and older vs. those younger than 50 (18% vs. 9%, respectively, P = .01), Whites vs. Asians (41% vs. 11%, P < .001), and in those who had been on TDF vs. ETV (17% vs. 12%, P = .001). There was no significant difference in cumulative HBsAg loss between patients who were HBeAg positive or negative at the start of NA therapy.
Cumulative rates of retreatment were 30% at 1 year, 43% at 2 years, 50% at 3 years, and 56% at 4 years. The only significant predictor for retreatment was age, with patients 50 and older being significantly more likely to be retreated by year 4 (63% vs. 45%, respectively, P < .001).
In a univariate model for HBsAg loss, the HR for age 50 and older was 1.7 (P = .01), the HR for White vs. Asian patients was 5.5 (P < .001), and the HR for TDF vs. ETV was 2.0 (P = .001).
A univariate model for retreatment showed an HR of 1.6 for patients 50 and older; all other parameters (sex, race, NA type, and HBeAg status at start of therapy) were not significantly different.
In multivariate models, only race/ethnicity remained significant as a predictor for HBsAg loss, with a HR of 5.8 for Whites vs. Asians (P < .001), and only age 50 and older remained significant as a predictor for retreatment, with a HR of 1.6 (P < .001).
The 4-year cumulative rate of virologic relapse, defined as an HBV DNA of 2000 IU/mL or higher) was 74%, the rate of combined DNA plus ALT relapse (ALT 2 or more times the upper limit of normal) was 56%, and the rate of ALT flares (5 or more times the upper limit of normal) was 33%.
In all, 15 patients (1%) experienced hepatic decompensation, and 12 (0.96%) died, with 9 of the deaths reported as liver-related.
Race/ethnicity differences previously seen
Liver specialist Anna Suk-Fong Lok, MD, professor of medicine at the University of Michigan in Ann Arbor, who was not involved in the study, said that the findings are not especially surprising.
“When the studies came out from Asian countries showing that patients who were taken off treatment had a higher rate of S antigen loss than patients who stayed on treatment, the rate of S antigen loss was not all that impressive, but when you look at the European studies the rate of S antigen loss was very high,” she said in an interview.
“The question of course is ‘Why?’ I don’t think we understand completely why. We can speculate, but none of these type studies give us a definitive answer,” she said.
Possible reasons for the racial differences in HBsAg loss include differences in hepatitis B genotype, she said.

HCC rates slow in cities, continue to climb in rural areas
The incidence rate of hepatocellular carcinoma in urban areas of the United States began to slow in 2009, but the rate in rural areas of the nation continued to rise at a steady pace, especially among non-Hispanic Whites and Blacks, investigators have found.
Although overall hepatocellular carcinoma (HCC) incidence rates were consistently lower among people living in nonmetro (rural) versus metro (urban) areas, the average annual percentage change in urban areas began to slow from 5.3% for the period of 1995 through 2009 to 2.7% thereafter. In contrast, the average annual percentage change in rural areas remained steady at 5.7%, a disparity that remained even after adjusting for differences among subgroups, reported Christina Gainey, MD, a third-year resident in internal medicine at the University of Southern California Medical Center, Los Angeles.
“We found that there are striking urban-rural disparities in HCC incidence trends that vary by race and ethnicity, and these disparities are growing over time,” she said during the virtual annual meeting of the American Association for the Study of Liver Diseases.
“Our study really highlights a critical public health issue that’s disproportionately affecting rural Americans. They already face considerable health inequities when it comes to access to care, health outcomes, and public health infrastructure and resources, and as of now we still don’t know why cases of HCC continue to rise in these areas,” she said.
Dr. Gainey noted that HCC is the fastest-growing cancer in the United States, according to the 2020 Annual Report to the Nation on the Status of Cancer, issued jointly by the Centers for Disease Control and Prevention, the North American Association of Central Cancer Registries, the American Cancer Society, and the National Cancer Institute.
Previous studies have identified disparities between urban and rural regions in care of patients with cervical cancer, colorectal cancer, and other malignancies, but there are very few data on urban-rural differences in HCC incidence, she said.
Incidence trends
To better understand whether such differences exists, the investigators compared trends in age-adjusted incidence rates of HCC in both rural and urban areas of the United States from 1995 to 2016, with stratification of trends by race/ethnicity and other demographic factors.
They drew from the NAACR database, which captures 93% of the U.S. population, in contrast to the CDC’s Surveillance, Epidemiology, and End Results (SEER) database which samples just 18% of the population.
Patients with HCC were defined by diagnostic codes, with diagnoses of intrahepatic bile duct cancers excluded.
They used 2013 U.S. Department of Agriculture Rural-Urban Continuum Codes to identify rural areas (regions of open countryside with town populations fewer than 2,500 people) and urban areas (populations ranging from 2,500 to 49,999, but not part of a larger labor market area).
The investigators identified a total of 310,635 HCC cases, 85% in urban areas and 15% in rural areas. Three-fourths of the patients (77%) were male. The median age ranged from 55-59 years.
There were notable demographic differences between the regions with non-Hispanic Whites comprising only 57% of the urban sample, but 82% of the rural sample. The urban sample included 16% non-Hispanic Blacks, 10% Asian/Pacific Islanders, and 17% Hispanics. The respective proportions in the rural areas were 8%, 2%, and 8%.
As noted before, age-adjusted incidence rates (adjusted to the year 2000 U.S. population) were lower in rural areas, at 4.9 per 100,000 population, compared with 6.9/100,000 in urban areas.
But when they looked at the average annual percentage changes using jointpoint regression, they saw that beginning in 2009 the AAPC in urban areas began to slow, from 5.3% for the period prior to 2009 to 2.7% thereafter, while the average annual percentage change in urban areas remained steady at 5.7%.
The largest increase in incidence over the course of the study was among rural non-Hispanic Whites, with an AAPC of 5.7%. Among urban non-Hispanic Blacks, the AAPC rose by 6.6% from 1995 to 2009, but slowed thereafter.
In contrast, among rural non-Hispanic Blacks the AAPC remained steady, at 5.4%.
The only group to see a decline in incidence was urban Asians/Pacific Islanders, who had an overall decline of 1%.
Among all groups, rural Hispanics had the highest age-adjusted incidence rates, at 14.9 per 100,000 in 2016.
Awareness gap?
Lewis R. Roberts, MB, ChB, PhD, a hepatobiliary cancer researcher at the Mayo Clinic in Rochester, Minn., who was not involved in the study, said in an interview that the difference in incidence rates between cities and the country may be attributable to a number of factors, including the opioid crisis, which can lead to an increase in injectable drug use or sexual behaviors resulting in increases in chronic hepatitis C infections and cirrhosis, known risk factors for HCC, as well as a lack of awareness of infections as a risk factor.
“In order for people to find these diseases, they have to be looking, and many of these are hidden diseases in our community,” he said. “What the study made me wonder was whether it just happens to be that they are in some ways more hidden in a rural community than they are in an urban community.”
He noted that clinicians in urban communities are more accustomed to treating more diverse populations who may have higher susceptibility to viral hepatitis, for example, and that screening and treatment for hepatitis C may be more common in urban areas than rural areas, he said.
No funding source for the study was reported. Dr. Gainey and Dr. Roberts reported having no conflicts of interest to disclose.

Mitotic rate makes comeback as melanoma prognosticator
at a virtual forum on cutaneous malignancies jointly presented by Postgraduate Institute for Medicine and Global Academy for Medical Education.
Dr. Kashani-Sabet, a dermatologist, director of the melanoma research program, and senior scientist at the California Pacific Medical Center Research Institute, San Francisco, was first author of a large recently published study that made a strong case for reincorporation of mitotic index into the American Joint Cancer Committee (AJCC) melanoma staging system.
Mitotic index was included in the 7th edition of the AJCC classification system, but was dropped from the current 8th edition in part because of concern it could potentially lead to overtreatment of patients with very thin melanomas of less than 0.5-mm thickness.
However, mitotic rate, like tumor thickness, is a continuous variable. And like tumor thickness, mitotic rate has a nonlinear relationship with survival. That’s why the AJCC staging system utilizes unequally spaced tumor thickness cut points of 1, 2, and 4 mm to define T1-T4 disease. But until the study led by Dr. Kashani-Sabet, optimal cut points for mitotic rate hadn’t been defined.
He and his coinvestigators at Melanoma Institute Australia collected a dataset comprising 5,050 patients with primary cutaneous melanoma in Australia and Northern California, all of whom either died of metastatic melanoma or remained distant metastasis–free for at least 8 years of follow-up. Median follow-up of the cohort was 9.5 years.
The investigators developed computer-generated cut points for mitotic rate and its impact on survival for each melanoma T category, then assessed their value in randomly split training and validation sets from their large cohort. For T1 melanoma, the optimal cut point proved to be 2 mitoses/mm2; more than two was independently associated with increased mortality risk. For T2 disease, the optimal cut point was 4, for T3 it was 6, and for T4 it was 7 mitoses/mm2.
A key study finding: In a multivariate regression analysis, tumor thickness was associated with survival, with an odds ratio of 1.58, ulceration had an odds ratio of 1.55, and mitotic rate by cut point had an odds ratio of 5.38. Each of these three characteristics was independently associated with survival (P < .00005). Dr. Kashani-Sabet said that, despite the more than threefold greater odds ratio for mitotic rate, compared with ulceration, in a Kaplan-Meier analysis, the survival impact of ulceration being present was “virtually identical” to an elevated mitotic rate in each T category.
He and his coinvestigators proposed a revised T-category system which incorporates this new insight. There is no change in tumor thickness to define T1-T4 melanoma: T1 is less than 1.0 mm, T2 is greater than 1-2.0 mm, T3 is greater than 2.01-4.0 mm, and T4 is greater than 4.0 mm. But now, within each T category the proposal is that the “a” designation indicates neither ulceration nor an elevated mitotic rate is present, while “b” means ulceration and/or an elevated mitotic rate using the optimal cut point for that T category is present. In their Australian/Northern California dataset, these new T categories showed a distinct separation in cumulative survival.
Dr. Kashani-Sabet and coworkers have submitted a proposal to validate their results using the AJCC database. Based upon a first look at the numbers, “We think it’s really very likely that these observations can be reproduced in this most important of datasets,” he predicted.
During a panel discussion, Sancy Leachman, MD, PhD, offered a recent example from her own practice where an elevated mitotic index as defined by Dr. Kashani-Sabet and coworkers served as a red flag.
“I had a patient with a 0.3-mm melanoma with three mitoses. I did a sentinel lymph node biopsy on the patient, and she was positive,” said Dr. Leachman, professor and chair of the department of dermatology at Oregon Health & Science University, Portland.
Dr. Kashani-Sabet commented that, while an elevated mitotic index is clearly not an absolute requirement for metastasis, when present it’s a prognostically important finding.
Moreover, as adjuvant therapies of proven value in node-positive disease increasingly come under study in node-negative melanoma, it will be critical to identify the high-risk node-negative subgroup for whom such therapies should be targeted.
“While T4 tumors and ulcerated melanomas are clearly high risk, they’re not going to capture every patient who has a very high risk of distant metastases and death. I think mitotic rate is another pathway to identify patients who very well might benefit and should be candidates for inclusion in those adjuvant therapy trials as we’re moving more into node-negative patients,” according to Dr. Kashani-Sabet.
He reported having no financial conflicts of interest regarding his presentation.

Dr. Kashani-Sabet, a dermatologist, director of the melanoma research program, and senior scientist at the California Pacific Medical Center Research Institute, San Francisco, was first author of a large recently published study that made a strong case for reincorporation of mitotic index into the American Joint Cancer Committee (AJCC) melanoma staging system.
Mitotic index was included in the 7th edition of the AJCC classification system, but was dropped from the current 8th edition in part because of concern it could potentially lead to overtreatment of patients with very thin melanomas of less than 0.5-mm thickness.
However, mitotic rate, like tumor thickness, is a continuous variable. And like tumor thickness, mitotic rate has a nonlinear relationship with survival. That’s why the AJCC staging system utilizes unequally spaced tumor thickness cut points of 1, 2, and 4 mm to define T1-T4 disease. But until the study led by Dr. Kashani-Sabet, optimal cut points for mitotic rate hadn’t been defined.
He and his coinvestigators at Melanoma Institute Australia collected a dataset comprising 5,050 patients with primary cutaneous melanoma in Australia and Northern California, all of whom either died of metastatic melanoma or remained distant metastasis–free for at least 8 years of follow-up. Median follow-up of the cohort was 9.5 years.
The investigators developed computer-generated cut points for mitotic rate and its impact on survival for each melanoma T category, then assessed their value in randomly split training and validation sets from their large cohort. For T1 melanoma, the optimal cut point proved to be 2 mitoses/mm2; more than two was independently associated with increased mortality risk. For T2 disease, the optimal cut point was 4, for T3 it was 6, and for T4 it was 7 mitoses/mm2.
A key study finding: In a multivariate regression analysis, tumor thickness was associated with survival, with an odds ratio of 1.58, ulceration had an odds ratio of 1.55, and mitotic rate by cut point had an odds ratio of 5.38. Each of these three characteristics was independently associated with survival (P < .00005). Dr. Kashani-Sabet said that, despite the more than threefold greater odds ratio for mitotic rate, compared with ulceration, in a Kaplan-Meier analysis, the survival impact of ulceration being present was “virtually identical” to an elevated mitotic rate in each T category.

Harnessing the HIV care continuum model to improve HCV treatment success
Better linkage to care with providers who are familiar with both the HCV and HIV treatment cascade may not only improve access to HCV treatment, but it may also support patient retention, treatment adherence, and achievement of sustained virologic response (SVR) and viral suppression, said Stephanie LaMoy, CAN Community Health, North Point, Florida. She presented the results of a pilot study at the virtual Association of Nurses in AIDS Care 2020 Annual Meeting.
In an effort to identify strategies most important for improving care access among their patients with HCV, LaMoy and her colleagues assessed 12-month patient data collected from three of their clinics. These data were evaluated for HCV treatment access, engagement, and outcomes.
The pilot study included 126 patients who were reactive and another 24 HCV-positive patients who were referred from other sources. Active HCV infections requiring treatment were reported in 144 patients.
A total of 59 patients were linked to care but did not initiate treatment for their active infection. LaMoy said there were multiple causes, including homelessness, substance abuse, and inability to maintain contact.
In contrast, 85 patients with HCV infection started treatment, but 35 of these patients did not complete their regimen. Out of the 50 patients who reported completing treatment, 30 did not return to the clinic to confirm sustained viral suppression.
According to LaMoy, this raised a red flag, causing the investigators to consider a different approach to care.
HIV care continuum model and its role in HCV
To improve the rate at which patients with HCV infection complete treatment within their clinics, the researchers formed a panel to determine necessary interventions that could reduce barriers to care.
The HIV care continuum came into play. They chose this model based on knowledge that HCV and HIV share the same care continuum with similar goals in diagnosis, linkage to care, retention, and suppression.
Based on the consensus of the panel and consideration of the HIV care continuum model, they identified a number of interventions needed to mitigate HCV treatment barriers. These included the incorporation of peer navigators or linkage-to-care (LCC) coordinators, use of the mobile medical unit, greater implementation of onsite lab visits, and medication-assisted treatment.
The LCC coordinators proved to be particularly important, as these team members helped assist patients with social and financial support to address challenges with access to treatment. These coordinators can also help patients gain access to specialized providers, ultimately improving the chance of successful HCV management.
Additionally, LCC coordinators may help identify and reduce barriers associated with housing, transportation, and nutrition. Frequent patient contact by the LCC coordinators can encourage adherence and promote risk reduction education, such as providing referrals to needle exchange services.
“Linking individuals to care with providers who are familiar with the treatment cascade could help improve retention and should be a top priority for those involved in HCV screening and treatment,” said LaMoy. “An environment with knowledge, lack of judgment, and a tenacious need to heal the community that welcomes those with barriers to care is exactly what is needed for the patients in our program.”
National, community challenges fuel barriers to HCV treatment access
Substance use, trauma histories, and mental health problems can negatively affect care engagement and must be addressed before the benefits of HCV therapy can be realized.
Addressing these issues isn’t always easy, said Kathleen Bernock, FNP-BC, AACRN, AAHIVS, of the Bedford-Stuyvesant Family Health Center in New York City, in an email to Medscape Medical News. She pointed out that several states have harsh restrictions on who is able to access HCV treatment, and some states will not approve certain medications for people who actively use drugs.
“Even for states without these restrictions, many health systems are difficult to navigate and may not be welcoming to persons actively using,” said Bernock. Trauma-informed care can also be difficult to translate into clinics, she added.
“Decentralizing care to the communities most affected would greatly help mitigate these barriers,” suggested Bernock. Decentralization, she explained, might include co-locating services such as syringe exchanges, utilizing community health workers and patient navigators, and expanding capacity-to-treat to community-based providers.
“[And] with the expansion of telehealth services in the US,” said Bernock, “we now have even more avenues to reach people that we never had before.”
LaMoy and Bernock have disclosed no relevant financial relationships.

Abnormal anal paps in people with HIV can go more than a year without follow-up
That delay “revealed missed opportunities for a better experience on the patient, clinic, and provider level,” Jessica Wells, PhD, research assistant professor at the Nell Hodgson Woodruff School of Nursing at Emory University, Atlanta, said in an interview. After all, “a lot can happen in that 1 year,” including early development of human papillomavirus (HPV)–associated anal cancer.
Although it’s too soon to say how significant that delay is with respect to the natural history of anal cancer, Dr. Wells said the data are a potential signal of disparities.
“The findings from my study may foreshadow potential disparities if we don’t have the necessary resources in place to promote follow-up care after an abnormal Pap test, similar to the disparities that we see in cervical cancer,” she said during the virtual Association of Nurses in AIDS Care 2020 Annual Meeting.
Single-center study
In the United States, people living with HIV are 19 times more likely to develop anal cancer than the general population, according to a 2018 article in the Journal of Clinical Oncology. Another single-center study from Yale University found that, in minority communities, anal cancer rates were 75% higher than in White communities. Anal cancer rates were 72% higher in communities with greater poverty. As a result, many clinics are beginning to administer Pap tests to determine early signs of HPV infection and associated changes.
In Dr. Wells’ study, which was conducted from 2012 to 2015, 150 adults with HIV who were aged 21 and older were recruited from Grady Ponce De Leon Center in Atlanta. According to a 2018 study from that center, a large minority of participants had late-stage HIV and suppressed immune systems.
All participants had been referred for HRA after a recent abnormal anal Pap test. Participants filled out questionnaires on sociodemographics, internalized HIV-related stigma, depression, risk behaviors, social support, and knowledge about HPV and anal cancer.
Participants were disproportionately older (mean age, 50.9 years); cisgender (86.7%), Black (78%); and gay, lesbian, or bisexual (84.3%). Slightly more than 1 in 10 participants (11.3%) were transgender women.
Although for 6% of participants, Pap test results indicated high-grade squamous intraepithelial lesions (HSIL), an additional 8% had atypical Pap findings that couldn’t exclude HSIL – the kinds of results that are one step away from a cancer diagnosis. More than 80% of participants had low-grade or inconclusive results. Nearly half (44%) of participants’ Pap tests revealed low-grade squamous cell intraepithelial cell lesions (LSIL); 42% indicated atypical squamous cells of undetermined significance.
When Dr. Wells looked at how long participants had waited to undergo HRA, she found something that surprised her: although some participants underwent follow-up assessment in 17 days, for many, it took much longer. The longest wait was 2,350 days – more than 6 years.
“There were quite a few patients who had follow-up beyond 1,000-plus days,” Dr. Wells said in an interview. “I didn›t think the delays were that long — at most, I would say that patients will get scheduled and come back within a few weeks or months.”
What’s more, she discovered through the HPV knowledge questionnaire that many participants did not understand why they were having a follow-up appointment. Anecdotally, some confused HPV with HIV.
“There’s education to be done to inform this target population that those living with HIV are more prone or at increased risk of this virus causing cancer later,” she said. “There are a lot of campaigns around women living with HIV, that they need to do cervical cancer screening. I think we need to really expand this campaign to include that HPV can also cause anal cancer.”
Dr. Wells had planned to primarily investigate the impact of psychosocial factors on wait time to follow-up, but none of those factors were associated with longer wait times.
Systems-level factors
That led Ann Gakumo, PhD, chair of nursing at the College of Nursing and Health Sciences of the University of Massachusetts, Boston, to ask what other factors could account for the delay.
There were several, Dr. Wells said. Precarious housing, for example, could have influenced this lag in follow-up. About one in four participants were in transient housing, and one participant reported having been incarcerated. She gathered street addresses and plans to analyze that data to see whether the cases occurred in clusters in specific neighborhoods, as the Yale data indicated.
In addition, the anoscopy clinic was only available to receive patients one day a week and was staffed with only one clinician who was trained to perform HRA. Wait times could stretch for hours. Sometimes, participants had to leave the clinic to attend to other business, and their appointments needed to be rescheduled, Wells said.
In addition to the sometimes poor understanding of the importance of the follow-up test, Dr. Wells said, “we start to see a layering of these barriers. That’s where we start seeing breakdowns. So I’m hoping in a larger study I can address some of these barriers on a multilevel approach.”
This resonated with Dr. Gakumo.
“Oftentimes, we put so much of the responsibility for this on the part of the client and not enough on the part of the provider or on the systems level,” she said.
Guiding guidelines
Guidelines on follow-up for abnormal anal Pap test results are scarce, mostly because, unlike cervical cancer, the natural history of HPV-related anal cancers hasn’t been established. The HIV Medical Association does recommend anal Pap tests, but only in cases in which “access to appropriate referral for follow-up, including high-resolution anoscopy, is available.”
In an interview, Cecile Lahiri, MD, assistant professor of infectious disease at Emory University, said that, at Ponce De Leon Center, they recommend an anal Pap for women with HIV who have a history of cervical dysplasia.
There is a reliable association between high-grade abnormal Pap tests and cervical cancer, although low-grade changes can resolve on their own. In the case of anal cancer, especially in patients with HIV, low-grade cell changes are predictive; moreover, for such patients, anal cancer is more likely to recur and is harder to treat, Dr. Lahiri said.
“The cervical environment and the anal environment are very different,” said Dr. Lahiri, who works at the Grady Ponce De Leon Center but was not involved in Dr. Wells’ study. Dr. Lahiri is also a coinvestigator of the multisite, randomized, controlled Anal Cancer HSIL Outcomes Research (ANCHOR) study, which seeks to establish whether early treatment of high-grade anal Pap changes is better than a watch-and-wait approach.
Dr. Lahiri said that when the results of that trial become available, they are more likely to know how important early anoscopy and treatment are. The findings should inform guidelines and insurance coverage of anal Pap tests and anoscopy.
In the meantime, she said, she suspected that, with the ANCHOR trial in 2015, many sites’ capacity for anoscopy may have increased, and the wait times may have gone down.
“One of the most important pieces of the study is actually the time period in which it was conducted,” said Dr. Lahiri, who in 2015 became the clinic’s second physician trained in anoscopy. Currently, more than 200 people at the Ponce De Leon Center are enrolled in the ANCHOR trial. In addition, the general capacity for performing anoscopies has gone up nationwide as a result of the trial, which required that more providers learn how to properly perform an HRA. Many clinicians are not routinely trained in performing HRA, including gastroenterologists and surgeons, Dr. Lahiri said.
“It would be interesting to look at the differences, with the start of ANCHOR being the time point for before and after,” she said.

When Dr. Wells looked at how long participants had waited to undergo HRA, she found something that surprised her: although some participants underwent follow-up assessment in 17 days, for many, it took much longer. The longest wait was 2,350 days – more than 6 years.
“There were quite a few patients who had follow-up beyond 1,000-plus days,” Dr. Wells said in an interview. “I didn›t think the delays were that long — at most, I would say that patients will get scheduled and come back within a few weeks or months.”
What’s more, she discovered through the HPV knowledge questionnaire that many participants did not understand why they were having a follow-up appointment. Anecdotally, some confused HPV with HIV.
“There’s education to be done to inform this target population that those living with HIV are more prone or at increased risk of this virus causing cancer later,” she said. “There are a lot of campaigns around women living with HIV, that they need to do cervical cancer screening. I think we need to really expand this campaign to include that HPV can also cause anal cancer.”
Dr. Wells had planned to primarily investigate the impact of psychosocial factors on wait time to follow-up, but none of those factors were associated with longer wait times.
Systems-level factors
That led Ann Gakumo, PhD, chair of nursing at the College of Nursing and Health Sciences of the University of Massachusetts, Boston, to ask what other factors could account for the delay.
There were several, Dr. Wells said. Precarious housing, for example, could have influenced this lag in follow-up. About one in four participants were in transient housing, and one participant reported having been incarcerated. She gathered street addresses and plans to analyze that data to see whether the cases occurred in clusters in specific neighborhoods, as the Yale data indicated.
In addition, the anoscopy clinic was only available to receive patients one day a week and was staffed with only one clinician who was trained to perform HRA. Wait times could stretch for hours. Sometimes, participants had to leave the clinic to attend to other business, and their appointments needed to be rescheduled, Wells said.
In addition to the sometimes poor understanding of the importance of the follow-up test, Dr. Wells said, “we start to see a layering of these barriers. That’s where we start seeing breakdowns. So I’m hoping in a larger study I can address some of these barriers on a multilevel approach.”
This resonated with Dr. Gakumo.
“Oftentimes, we put so much of the responsibility for this on the part of the client and not enough on the part of the provider or on the systems level,” she said.
Guiding guidelines
Guidelines on follow-up for abnormal anal Pap test results are scarce, mostly because, unlike cervical cancer, the natural history of HPV-related anal cancers hasn’t been established. The HIV Medical Association does recommend anal Pap tests, but only in cases in which “access to appropriate referral for follow-up, including high-resolution anoscopy, is available.”
In an interview, Cecile Lahiri, MD, assistant professor of infectious disease at Emory University, said that, at Ponce De Leon Center, they recommend an anal Pap for women with HIV who have a history of cervical dysplasia.
There is a reliable association between high-grade abnormal Pap tests and cervical cancer, although low-grade changes can resolve on their own. In the case of anal cancer, especially in patients with HIV, low-grade cell changes are predictive; moreover, for such patients, anal cancer is more likely to recur and is harder to treat, Dr. Lahiri said.
“The cervical environment and the anal environment are very different,” said Dr. Lahiri, who works at the Grady Ponce De Leon Center but was not involved in Dr. Wells’ study. Dr. Lahiri is also a coinvestigator of the multisite, randomized, controlled Anal Cancer HSIL Outcomes Research (ANCHOR) study, which seeks to establish whether early treatment of high-grade anal Pap changes is better than a watch-and-wait approach.
Dr. Lahiri said that when the results of that trial become available, they are more likely to know how important early anoscopy and treatment are. The findings should inform guidelines and insurance coverage of anal Pap tests and anoscopy.
In the meantime, she said, she suspected that, with the ANCHOR trial in 2015, many sites’ capacity for anoscopy may have increased, and the wait times may have gone down.
“One of the most important pieces of the study is actually the time period in which it was conducted,” said Dr. Lahiri, who in 2015 became the clinic’s second physician trained in anoscopy. Currently, more than 200 people at the Ponce De Leon Center are enrolled in the ANCHOR trial. In addition, the general capacity for performing anoscopies has gone up nationwide as a result of the trial, which required that more providers learn how to properly perform an HRA. Many clinicians are not routinely trained in performing HRA, including gastroenterologists and surgeons, Dr. Lahiri said.
“It would be interesting to look at the differences, with the start of ANCHOR being the time point for before and after,” she said.

That delay “revealed missed opportunities for a better experience on the patient, clinic, and provider level,” Jessica Wells, PhD, research assistant professor at the Nell Hodgson Woodruff School of Nursing at Emory University, Atlanta, said in an interview. After all, “a lot can happen in that 1 year,” including early development of human papillomavirus (HPV)–associated anal cancer.
Although it’s too soon to say how significant that delay is with respect to the natural history of anal cancer, Dr. Wells said the data are a potential signal of disparities.
“The findings from my study may foreshadow potential disparities if we don’t have the necessary resources in place to promote follow-up care after an abnormal Pap test, similar to the disparities that we see in cervical cancer,” she said during the virtual Association of Nurses in AIDS Care 2020 Annual Meeting.
Single-center study
In the United States, people living with HIV are 19 times more likely to develop anal cancer than the general population, according to a 2018 article in the Journal of Clinical Oncology. Another single-center study from Yale University found that, in minority communities, anal cancer rates were 75% higher than in White communities. Anal cancer rates were 72% higher in communities with greater poverty. As a result, many clinics are beginning to administer Pap tests to determine early signs of HPV infection and associated changes.
In Dr. Wells’ study, which was conducted from 2012 to 2015, 150 adults with HIV who were aged 21 and older were recruited from Grady Ponce De Leon Center in Atlanta. According to a 2018 study from that center, a large minority of participants had late-stage HIV and suppressed immune systems.
All participants had been referred for HRA after a recent abnormal anal Pap test. Participants filled out questionnaires on sociodemographics, internalized HIV-related stigma, depression, risk behaviors, social support, and knowledge about HPV and anal cancer.
Participants were disproportionately older (mean age, 50.9 years); cisgender (86.7%), Black (78%); and gay, lesbian, or bisexual (84.3%). Slightly more than 1 in 10 participants (11.3%) were transgender women.
Although for 6% of participants, Pap test results indicated high-grade squamous intraepithelial lesions (HSIL), an additional 8% had atypical Pap findings that couldn’t exclude HSIL – the kinds of results that are one step away from a cancer diagnosis. More than 80% of participants had low-grade or inconclusive results. Nearly half (44%) of participants’ Pap tests revealed low-grade squamous cell intraepithelial cell lesions (LSIL); 42% indicated atypical squamous cells of undetermined significance.
When Dr. Wells looked at how long participants had waited to undergo HRA, she found something that surprised her: although some participants underwent follow-up assessment in 17 days, for many, it took much longer. The longest wait was 2,350 days – more than 6 years.

‘Uptake is only the first step’ for effective HIV PrEP protection
To Amanda Allmacher, DNP, RN, nurse practitioner at the Detroit Public Health STD Clinic, that means that same-day PrEP prescribing works and is acceptable. But there’s more work to do on the clinic and pharmacy side to make HIV protection a reality for most of her patients. Allmacher presented her data at the Association of Nurses in AIDS Care 2020 virtual annual meeting.
Dawn K. Smith, MD, epidemiologist and medical officer in the Division of HIV/AIDS Prevention at the Centers for Disease Control and Prevention’s National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention, said this adds to other data to show that we’re now entering the next phase of PrEP implementation.
“Our original focus was on uptake — informing folks what PrEP is, why they might benefit from its use, and then prescribing it if accepted,” Smith told Medscape Medical News via email. “Whether standard or same-day [PrEP prescribing], it is clear that uptake is only the first step.”
Nurses help navigate
Patients who attended the Detroit Public Health STD Clinic are more likely to be younger, have no insurance, and otherwise “have little to no contact with the healthcare system,” Allmacher said in her presentation. They also tend to come from communities that bear the greatest burden of HIV in the US — in other words, they are often the people most missed in PrEP rollouts thus far.
In response, the clinic implemented a same-day PrEP protocol, in which registered nurses trained in HIV risk assessment identify clients who might most benefit from PrEP. Criteria often include the presence of other STIs. Once the nurse explains what PrEP is and how it works, if the patient is interested, clients meet with a nurse practitioner right then to get the prescription for PrEP. The clinic also does labs to rule out current HIV infection, hepatitis B, metabolic issues, and other STI screening.
But it doesn’t stop there. The clinic used grant funding to offer PrEP navigation and financial counseling services, which help clients navigate the sometimes-thorny process of paying for PrEP. Payment comes either through Medicaid, which in Michigan charges $3 a month for a PrEP prescription, through patient assistance programs, or through private insurance. With clients under age 18 who are interested in PrEP, the clinic works to find a way to access PrEP without having to inform their parents. These same navigators schedule follow-up appointments, offer appointment reminders, and contact clients when they miss an appointment.
“Our navigators and financial counselors are a huge support for our same-day PrEP starts, helping with financial assistance, prior authorization, navigating different plans, and helping patients apply for Medicaid when appropriate,” she said.
The clinic also offers community outreach and incentives, which can include gift cards, bus passes, and pill containers, among other things.
This was a key lesson in setting up the program, Allmacher told Medscape Medical News.
“Starting PrEP at that initial visit allows for clinicians to meet patients where they are and administer care in a more equitable manner,” Allmacher said via email. “Use all available resources and funding sources. We have a versatile team working together to increase access for patients and promote HIV prevention and risk reduction.”
Script vs. follow-up
This approach is common, used in places like New York City and San Francisco. So once it was set up Allmacher sat back and waited to see how the program helped clients protect themselves from HIV.
Of the 451 clients eligible for PrEP in 2019, 336 were gay and bisexual men, 6 were transgender women, 61 were heterosexual, cisgender men, and 48 were cisgender women. One transgender man also screened as eligible. Allmacher did not break down data by race.
Uptake was high: 70% of all eligible clients did receive a prescription for PrEP, either generic tenofovir disoproxil fumarate/emtricitabine (Truvada) or tenofovir alafenamide/emtricitabine (Descovy). And uptake was high among people most at risk: 80% of gay and bisexual men who were eligible got a prescription, 60% of eligible cisgender women, 50% of the small number of transgender women, and 32.7% of heterosexual cisgender men did as well. The 1 transgender man also received a prescription.
This is a higher rate than found in a recent PrEP demonstration project, which found that despite gay and bisexual men, transgender adults, and Black people having the highest risk for HIV in the US, state health departments were more likely to refer heterosexual adults for PrEP.
That high uptake rate is encouraging, but follow-up? Not so much. After initial intake, clients are meant to return in a month to double-check their labs, ask about side effects, and start their 90-day supply of the medication. But just 40% showed up for their 30-day appointment, Allmacher said. And only one third of those showed up for the follow-up in 90 days.
By the end of 2019, just 73 of the original 451 clients screened were still taking PrEP.
“It was surprising to see just how significant the follow-up dropped off after that first visit, when the patient initially accepted the prescription,” Allmacher said.
And while it’s possible that some clients get their follow-up care from their primary care providers, “our clinic serves individuals regardless of insurance status and many do not identify having access to primary care for any type of service, PrEP or otherwise,” she said.
5 HIV acquisitions
In addition, the program review identified five clients who had been offered PrEP or had taken PrEP briefly who later acquired HIV. Those clients were offered same-day antiretroviral treatment, Allmacher said.
“So we’re finding people who are at high risk for HIV and we can prevent them, but we’re still not quite doing enough,” Allmacher said of those acquisitions. “Clearly we have a lot of work to do to focus on HIV prevention, and we are looking to create a more formal follow-up process” from the clinic’s side.
For instance, clinic staff call clients 1 week after their initial visit to share lab results. “This was identified as a missed opportunity for us to ask about their status, whether they filled their prescription, or if they need further assistance,” she said. “This is an area where our registered nurses are going to be taking on a greater role moving forward.”
Allmacher and team also discovered that, despite PrEP navigators arranging insurance coverage for clients on the day they receive their prescription, sometimes there were still barriers when the client showed up at the pharmacy to pick up their meds. The clinic does not have an in-house pharmacy and does not currently have the funding that would allow them to hand patients a bottle of the appropriate medication when they leave the clinic.
“Navigating the copays and the insurance coverage and using financial assistance through the drug manufacturer — even though we have the support in the clinic, it seems like there’s a disconnect between our clinic and getting to the pharmacy. Not every pharmacy is super familiar with navigating those,” she said. “So we have started to identify some area pharmacies near our clinic that are great at navigating these, and we really try to get our patients to go to places we know can give them assistance.”
