A study published in May in The Lancet journal eClinicalMedicine reports that breathomics testing is one step closer to becoming a reality as a lung cancer screening tool.

The tool was successfully used to identify, in 84 patients, 16 lung cancer–related carcinogenic volatile compounds (VOCs), such as aldehydes, hydrocarbons, ketones, carboxylic acids, and furan – some of which are compounds used in the production of common household goods, such as furniture, carpeting, and wood floors.

“The test is anticipated to be highlighted for primary screening of lung cancer but not the final diagnosis,” according to study authors who were led by Peiyu Wang, MD, PhD, chair of social medicine and health at Peking (China) University.

While early diagnosis and treatment are critical for improving lung cancer survival, early detection of lung cancer is challenging because of the lack of clinical manifestations and specific biomarkers. Annual CT scans are costly and include radiation exposure, Dr. Wang and his associates wrote.

Breathomics testing is considered a promising method for detection and screening for lung cancer. It has been under study for years and in 2014, researchers from Belgium published a review in Cancer Epidemiology Biomarkers and Prevention documenting the use of VOCs as early diagnostic or prognostic biomarkers for mesothelioma.

Lung cancer breath biomarkers identified in various studies have been highly heterogeneous because of differing sample collection methods, varying patient conditions, testing environments, and analysis methods. As a result, there currently is no breathomics test for lung cancer screening, Dr. Wang said in an interview.

In terms of its potential as a lung cancer screening tool, “Clinicians may introduce this test for people with high risk for lung cancer, such as elderly smokers, or people with suspected symptoms. It may also be introduced for young populations with subjective or objective needs to screen for lung cancer. As the proportion of lung adenocarcinoma in nonsmoking young women is increasing, the test may be a good method for lung cancer screening in this population,” Dr. Wang said.

After adjusting for age, sex, smoking, and comorbidities, researchers found elevated levels for 16 VOCs in patients with lung cancer. A diagnostic model including the 16 VOCs achieved an area under the curve of 0.952, sensitivity of 89.2%, specificity of 89.1%, and accuracy of 89.1% in lung cancer diagnosis. A model including the top eight VOCs achieved an area under the curve of 0.931, sensitivity of 86.0%, specificity of 87.2%, and accuracy of 86.9%.

After selecting 28 VOCs as candidates through a literature review, Dr. Wang and associates conducted a prospective discovery study from Sept. 1 to Dec. 31, 2020, using high-pressure photon ionization time-of-flight mass spectrometry to evaluate their performance for lung cancer diagnosis. The validation study included 157 lung cancer patients (mean age 57.0 years; 54.1 percent female) and 368 volunteers (mean age 44.5 years; 31.3% female).

“The external validation confirmed good performance of these biomarkers in lung cancer detection,” the researchers stated. It helped, they added, to solve the heterogeneity among published studies, establishing both 16 VOCs and 8 VOCS for lung cancer screening.

The authors stated that a large gap exists between breathomics research and clinical practices in lung cancer detection and screening. While the validated 16 VOCs, mainly aldehydes and hydrocarbon, showed potential for promoting this lung cancer screening strategy, more scientific studies are warranted to investigate the underlying mechanisms of identified lung cancer VOCs.

Dr. Wang declared no competing interests.

Immunotherapy with nivolumab (Opdivo) is now approved in the United States for first-line use in the treatment of unresectable advanced or metastatic esophageal squamous cell carcinoma (ESCC).

The new approval for the drug, a programmed cell death–ligand-1 inhibitor, is for use in this patient population regardless of PD-L1 status.

The indication also specifies that nivolumab is to be used together with chemotherapy (with a fluoropyrimidine- and platinum-containing regimen) or in combination with ipilimumab (Yervoy), an immunotherapy with a different mechanism of action.

“Today’s approvals bring two first-line immunotherapy-based treatment options at once ... to newly diagnosed patients with unresectable advanced or metastatic ESCC,” commented Adam Lenkowsky, a senior vice president at Bristol-Myers Squibb, which makes both nivolumab and ipilimumab.

The approval of the new indication by the Food and Drug Administration was based on improved survival shown in the phase 3 CheckMate-648 trial, which involved nearly 1,000 patients. The trial had three arms and compared nivolumab plus chemotherapy (n = 321) and nivolumab plus ipilimumab (n = 324) with chemotherapy alone (n = 324).

The results showed improved survival with both nivolumab combinations compared with chemotherapy (fluorouracil and cisplatin) alone. Overall survival was improved both in all randomized patients (a secondary endpoint) and in patients whose tumors expressed PD-L1 (≥ 1%), the primary endpoint.

For the combination of nivolumab plus chemotherapy, median overall survival was 13.2 versus 10.7 months, compared with chemotherapy alone in all randomized patients, and 15.4 versus 9.1 months in patients whose tumors express PD-L1 (≥ 1%).

For the combination of nivolumab plus ipilimumab, median overall survival was 12.8 versus 10.7 months with chemotherapy alone in all randomized patients and 13.7 versus 9.1 months in patients whose tumors express PD-L1 (≥ 1%).

However, progression-free survival did not reach statistical significance in any group.

“Unresectable advanced or metastatic ESCC is a challenging disease, and there’s a need for additional treatment options that may extend survival in the first-line setting,” commented Jaffer A. Ajani, MD, professor of gastrointestinal medical oncology at the University of Texas MD Anderson Cancer Center, Houston. He was also the lead U.S. investigator for CheckMate-648 and, in a company press release, said the “two nivolumab-based combinations showed a survival benefit compared to chemotherapy alone, offering new treatment options regardless of PD-L1 status.”

Results from the trial were presented at the 2021 annual meeting of the American Society of Clinical Oncology. At that time, trial investigator Ian Chau, MD, a consultant medical oncologist at the Royal Marsden Hospital in Sutton, England, told attendees that “nivolumab plus chemotherapy and nivolumab plus ipilimumab each represent a new potential first-line standard of care for patients with advanced ESCC.”

Commenting on that presentation, Samuel J. Klempner, MD, a gastrointestinal medical oncologist at the Massachusetts General Hospital Cancer Center, Boston, noted that the “prospect of a chemo-free regimen for advanced ESCC with the well-studied combination of ipilimumab and nivolumab would represent a welcome addition to our treatment armamentarium.”
 

No new safety signals

Dr. Chau noted there were no new safety signals with either of the immunotherapies.

Nivolumab and/or chemotherapy were discontinued in 39% of patients and delayed in 71% of patients for an adverse reaction.

Nivolumab and/or ipilimumab were discontinued in 23% of patients and delayed in 46% of patients for an adverse reaction.

The manufacturer cautioned that immunotherapy with nivolumab with or without ipilimumab has been associated with severe and fatal immune-mediated adverse reactions including pneumonitis, colitis, hepatitis and hepatotoxicity, endocrinopathies, nephritis and renal dysfunction, dermatologic adverse reactions, and infusion-related reactions.

Learning that a family member has cancer can be devastating enough. Waiting to find out whether a loved one can afford their treatment takes the concern to another level.

That was the case for health policy expert Stacie B. Dusetzina, PhD, when her mother was diagnosed with metastatic breast cancer.

“There is this period where you are waiting to learn more about the cancer type and treatment options, and, of course, what might be covered by your health plan,” Dr. Dusetzina, an associate professor at Vanderbilt University Medical Center, Nashville, Tenn., said in an interview. “Knowing as much as I do about coverage for prescription drugs in Medicare Part D, I was worried we would be in a situation where my mom had to spend over $15,000 out-of-pocket every year for one of these drugs.”

That $15,000 would have taken a large chunk of her retirement income and could make treatment unaffordable down the line.

This situation is hardly unique.

Many patients with cancer who rely on Medicare Part D face an impossible choice: “Your money or your life,” Dr. Dusetzina said.

In a recent perspective in the New England Journal of Medicine, Dr. Dusetzina detailed how subtle variations in people’s cancer type can have major implications for their out-of-pocket drug costs.

The difference in cost comes down to whether drugs are delivered as pills or infusions. Oral agents are almost always covered under a health plan’s pharmacy benefit (Medicare Part D), while physician-administered drugs are covered under the medical benefit (Medicare Part B).

According to Dr. Dusetzina, Medicare beneficiaries can face substantial, possibly “unlimited,” out-of-pocket costs for drugs covered under Part D if they don’t qualify for low-income subsidies. On the other hand, most beneficiaries receiving physician-administered drugs covered under Part B have supplemental coverage, which reduces or eliminates out-of-pocket costs.

Dr. Dusetzina broke down the expected first fill and yearly out-of-pocket costs associated with 10 oral cancer drugs covered under Part D. These costs ranged from $3,100 to $3,392 for a first fill and $10,592 to $14,067 for one year.

In a candid Twitter thread, Dr. Dusetzina opened up more about the issues highlighted in her piece: “This paper is about #PartD and Cancer. It is also about #pharmacoequity ... This is about how screwed you are if you need cancer treatment and your treatment happens to be covered by #PartD and not #PartB.”

“This is ARBITRARY and INEQUITABLE,” she added.

What’s “arbitrary,” Dr. Dusetzina explains, is that a rather small, chance distinction in cancer type or subtype can be the difference between affording and not affording treatment – and potentially between life and death.

Take the drug costs for two similar patients with breast cancer.

Patient A has hormone receptor–positive, human epidermal growth factor receptor type 2 (HER2)–negative breast cancer and thus would likely receive first-line therapy with two oral agents: an aromatase inhibitor and cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitor, most often palbociclib (Ibrance).

For palbociclib alone, out-of-pocket costs would come to $3,100 for the first fill and nearly $10,600 over a year for a Part D beneficiary who doesn’t qualify for low-income subsidies.

Now take patient B who has HER2–positive metastatic breast cancer. This person would likely receive first-line treatment with trastuzumab (Herceptin), pertuzumab (Perjeta), and a taxane – a combination covered under Part B, which would be subject to an out-of-pocket cap or covered with limited or no cost sharing.

This difference in cancer subtype leaves some patients “paying substantially more for their cancer treatment than others, despite the same goal of extending or improving their lives,” Dr. Dusetzina writes.

Time-restricted eating reduced cardiovascular risk among older breast cancer survivors, a single-group feasibility study suggests.

The results show a 15% relative decline in cardiovascular risk, measured using the Framingham Risk Score, among at-risk breast cancer survivors (BCS) after only 8 weeks of following a time-restricted eating regimen, reported Amy A. Kirkham, PhD, assistant professor of kinesiology and physical education, University of Toronto, and colleagues.

“Time-restricted eating also significantly decreased visceral adipose tissue (VAT), which our team has previously found to accumulate rapidly with cardiotoxic treatment and predict later cardiac events among BCS,” the researchers add.

The findings were published online in the Journal of the American College of Cardiology: Cardiac Onco.

Physical activity is one of the main modalities for lowering cardiovascular risk, but it is not feasible for everyone because of physical limitations and other factors, noted Dr. Kirkham.

“I became interested in time-restricted eating when I came across the literature, which has really exploded in the last 5 years, showing that it can reduce the number of cardiovascular risk factors,” she said in an interview.

“However, most of these populations studied have had cardiometabolic conditions, like obesity, type 2 diabetes, prediabetes, and metabolic syndrome, and no one has looked at this” in either the population specifically at high risk for cardiovascular disease or in patients with overt cardiovascular disease, she said.

This approach is easy for patients to follow and is much simpler than many of the other dietary patterns, noted Dr. Kirkham. “It simply consists of having a start time or end time to your eating, so it is easy to prescribe,” she said. “You can see how that is much easier for a doctor to explain to a patient than trying to explain how to meet the physical activity guidelines each week.”

“This particular study definitely shows that time-restricted eating can decrease the calorie intake, and I think by decreasing the calorie intake you definitely would improve the body weight, which has numerous benefits irrespective of how we arrive at the end goal which is including the cardiovascular risk factors,” said Ajay Vallakati, MBBS, physician and clinical assistant professor of internal medicine, the Ohio State University, Columbus, commenting on the study.

“I think time-restricted eating is a tool we should look at, and a bigger study would help us to recommend this for our patients,” Dr. Vallakati told this news organization.

The study involved 22 participants. Mean age was 66 years. Mean body mass index was 31 ± 5 kg/m². In the cohort, 91% of participants were taking aromatase inhibitors and tamoxifen at the time of the study, and 50% underwent left-sided radiation.

The study group included breast cancer survivors who had risk factors for cardiovascular disease mortality, including completion of cardiotoxic therapy, like anthracyclines, within 1-6 years, obesity/overweight, and older age, defined as 60 years of age or older.

Participants were allowed to eat freely between 12 PM and 8 PM on weekdays and any time during weekends. Outside of the allotted hours, they could only drink black coffee, water, or black tea for the 8-week study period. They were not under any other physical activity or dietary restrictions.

All were provided with behavioral support, such as check-in phone calls with the research team at 1-, 3-, and 6-week follow-up and pre-interventional calls from a registered dietitian. During weekdays, they also received automated text messages twice a day asking what time they started and stopped eating.

Irritability and headaches were among the transient, minor symptoms reported, the researchers say. The study group responded to nearly all of the text messages that they received from the researchers. The participants also followed through with the fast for a median 98% of the prescribed days by fasting for 16 or more hours.

The results showed that after 8 weeks, median Framingham cardiovascular risk declined from 10.9% to 8.6%, a 15% relative reduction (P = .037). Modifiable aspects of Framingham, such as systolic blood pressure, total cholesterol, and high-density lipoprotein, remained relatively consistent overall, however, suggesting variation between individuals in the etiology of the risk decline.

Caloric intake fell by a median of 450 kcal, representing a relative reduction of about 22% (P < .001), they note.

The findings also showed a decline in median derived whole-body fat mass (–0.9 kg; P = .046), body mass (–1.0 kg; P = .025), and mean MRI-derived VAT (–5%; P = .009).

Other data showed that the average BMI remained the same (P = .10).

At the beginning of the study, 68% of the cohort was considered cardiometabolically unhealthy, given the benchmarks for pharmacologic preventive therapy of cardiovascular risk or metabolic syndrome based on Canadian Cardiovascular Society recommendations.

Notably, 53% of the cohort was no longer classified as meeting the criteria for metabolic syndrome or for the therapeutic treatment of cardiovascular risk after the intervention.

The study’s limitations include its short duration, selection bias, and that it did not involve a control group, the researchers acknowledge.

“Randomized controlled trials are needed to confirm these findings and to evaluate the health benefits, including potential health care cost savings and safety of longer-term time-restricted eating,” the researchers conclude.

Dr. Vallakati and Dr. Kirkham report no relevant conflicts of interest.

A cohort study has found increases in mortality rates among women with non-endometrioid uterine carcinoma, despite incident rates that have stabilized. After correction with hysterectomy, mortality risk was about doubled for Black women, compared with White women, and these results could not be explained by differences in cancer subtype or cancer stage at diagnosis. Non-endometroid uterine carcinoma represents 15%-20% of uterine cancers diagnosed and carries a worse prognosis.

“We do not know why non-endometrioid subtypes are disproportionately increasing among all women, nor do we understand why they are so much more common among non-Hispanic Black women. We need more research to identify risk factors and exposures more specifically associated with non-endometrioid cancers to better understand the strong increases in this subtype among all women and the particularly high rates and recent increases in non-Hispanic black women,” said lead author Megan Clarke, PhD, MHS, the study’s lead author and a cancer epidemiologist with the National Cancer Institute.

The study was published online in JAMA Oncology.

“Physicians should be aware that both incidence and mortality rates of non-endometrioid cancers are on the rise. Because these subtypes are rarer than endometrioid uterine cancers, physicians may be less familiar with diagnosing and treating these aggressive types of cancers. Increasing awareness among clinicians and patients regarding the signs and symptoms of uterine cancer (such as postmenopausal bleeding) and the differences in histologic subtypes among racial and ethnic groups may promote earlier diagnosis and timely referral to appropriate treatment,” Dr. Clarke said.

Previous studies based on death certificates found increased mortality, especially in Black women, but they were limited by an inability to link mortality to tumor characteristics. To address this, the researchers linked mortality data to records of 208,587 women diagnosed with uterine cancer between 2000 and 2017, drawn from the U.S. Surveillance, Epidemiology, and End Results (SEER) Program.

Black women represented 9.7% of cases, but they suffered 17.7% of uterine cancer deaths. Overall, mortality from uterine corpus cancer increased by 1.8% per year (95% confidence interval, 1.5%-2.9%). Non-endometroid cancers increased at 2.7% per year (95% CI, 1.8%-3.6%), and this was higher in Asian (3.4%; 95% CI, 0.3%-6.6%), Black (3.5%; 95% CI, 2.2%-4.9%), Hispanic (6.7%; 95% CI, 1.9%-11.8%), and White women (1.5%; 95% CI, 0.6%-2.4%).

Mortality increased 1.8% per year overall for uterine cancer and 2.7% per year for non-endometrioid uterine cancer. There was no increase in mortality seen in endometrioid cancers.

“The concerning rise in deaths from non-endometrioid cancers warrants clinical attention. Our findings suggest that there may be several factors contributing to racial disparities in uterine cancer mortality. Higher mortality rates among non-Hispanic Black women are partly attributable to higher incidence of tumors with aggressive subtypes and advanced stages. However, non-Hispanic Black women in our study who were diagnosed with less aggressive subtypes and early-stage disease also had the highest mortality rates,” said Dr. Clarke.

That suggests that inequities of treatment and high-quality care may be at least partly to blame, since those factors are known to contribute to differences in uterine cancer outcomes. “Other factors including comorbidities, health care facility characteristics, treatment preferences and adherence, patient and provider communication, provider bias, discrimination and structural racism, and potential biologic differences in response to treatment need to be better understood in terms of how they influence racial disparities,” Dr. Clarke said.

Dr. Clarke reported no relevant disclosures.

In the largest investigation into the issue to date, metformin did not improve survival of patients with high-risk, operable breast cancer when added to standard adjuvant treatments.

Metformin, a common option for patients with type 2 diabetes, had previously been shown in observational studies to be associated with improved survival of cancer patients. Those studies mostly involved older patients with cancer who also had diabetes.

These findings have led to trials of the use of metformin for patients with cancer who do not have diabetes, but two lung cancer trials found no effect on survival.

Now this latest trial in breast cancer, which included 3,649 patients with hormone receptor–positive or –negative disease – who did not have diabetes – also found that metformin had no effect on survival.

These results “tell us that metformin is not effective against the most common types of breast cancer and any off-label use [of] this drug for the treatment of these common types of breast cancer should be stopped,” lead investigator and medical oncologist Pamela Goodwin, MD, a breast cancer researcher at the Lunenfeld-Tanenbaum Research Institute in Toronto, said in a press release.

The negative results “underscore the need for well-conducted randomized trials” before observational studies are put into practice, Dr. Goodwin and her team said.

However, the investigators cautioned against extrapolating their results to patients with diabetes, noting that “because metformin is effective in type 2 diabetes, the results ... should not affect the use of metformin” in breast cancer patients who have diabetes.

The study was published online in JAMA.

Patients were enrolled from 2010 to 2013 while undergoing adjuvant treatment – chemotherapy, radiotherapy, hormone therapy, and/or others – following complete resection of T1-3, N0-3 tumors. They were almost exclusively women (mean age, 52.4 years), and almost 90% were non-Hispanic White. They were primarily from the United States and Canada, with some patients from the United Kingdom and Switzerland.

Patients were randomly assigned equally to receive either metformin 850 mg twice daily or placebo for 5 years. Median follow-up was about 8 years.

Among 2,533 patients with estrogen receptor– and/or progesterone receptor–positive disease, the incidence of invasive disease–free survival events was 2.78 per 100 patient-years in the metformin group, vs. 2.74 per 100 patient-years in the placebo arm (hazard ratio [HR], 1.01, P = .93). There were 1.46 deaths per 100 patient-years with metformin, vs. 1.32 with placebo (HR, 1.10, P = .47).

Metformin was stopped early at about 3 years for the 1,116 hormone receptor–negative patients after futility was declared on interim analysis. The incidence of invasive disease–free survival events was 3.58 with metformin, vs. 3.60 with placebo per 100 patient-years (HR, 1.01, P = .92). There were 1.91 deaths per 100 patient-years in the metformin arm, vs. 2.15 in the group that received placebo (HR, 0.89, P = .46).

However, the findings were different and suggested a signal among the small subset of patients (17% of the total) who had HER2-positive disease. There were 1.93 disease-free survival events with metformin per 100 patient-years, vs. 3.05 events with placebo (HR, 0.64, P = .03), and 0.78 deaths in the metformin arm, vs. 1.43 deaths per 100 patient-years in the placebo arm (HR, 0.54, P = .04).

The benefit seen in this HER2-postive subgroup was limited to patients with any C allele of the rs11212617 single-nucleotide variant.

This was an exploratory analysis, so the results need to be confirmed in a randomized trial, but it’s possible that metformin “could provide an additional treatment option for HER2-positive breast cancer,” Dr. Goodwin said.

Grade 3 or higher adverse events were more common with metformin (21.5% vs. 17.5%). The most common such events were hypertension (2.4% vs. 1.9%), irregular menses (1.5% vs. 1.4%), and diarrhea (1.9% vs. 0.8%).

The study was conducted by the Canadian Cancer Trials Group and was funded by the Canadian Cancer Society, the National Cancer Institute, and others. Dr. Goodwin has disclosed no relevant financial relationships. Several coauthors reported ties to Pfizer, Eli Lilly, Roche, and a number of other companies. One coauthor is an AstraZeneca employee.

There were 1.91 deaths per 100 patient-years in the metformin arm, vs. 2.15 in the group that received placebo (HR, 0.89, P = .46).

However, the findings were different and suggested a signal among the small subset of patients (17% of the total) who had HER2-positive disease. There were 1.93 disease-free survival events with metformin per 100 patient-years, vs. 3.05 events with placebo (HR, 0.64, P = .03), and 0.78 deaths in the metformin arm, vs. 1.43 deaths per 100 patient-years in the placebo arm (HR, 0.54, P = .04).

The benefit seen in this HER2-postive subgroup was limited to patients with any C allele of the rs11212617 single-nucleotide variant.

This was an exploratory analysis, so the results need to be confirmed in a randomized trial, but it’s possible that metformin “could provide an additional treatment option for HER2-positive breast cancer,” Dr. Goodwin said.

Grade 3 or higher adverse events were more common with metformin (21.5% vs. 17.5%). The most common such events were hypertension (2.4% vs. 1.9%), irregular menses (1.5% vs. 1.4%), and diarrhea (1.9% vs. 0.8%).

The study was conducted by the Canadian Cancer Trials Group and was funded by the Canadian Cancer Society, the National Cancer Institute, and others.

In the largest investigation into the issue to date, metformin did not improve survival of patients with high-risk, operable breast cancer when added to standard adjuvant treatments.

Metformin, a common option for patients with type 2 diabetes, had previously been shown in observational studies to be associated with improved survival of cancer patients. Those studies mostly involved older patients with cancer who also had diabetes.

These findings have led to trials of the use of metformin for patients with cancer who do not have diabetes, but two lung cancer trials found no effect on survival.

Now this latest trial in breast cancer, which included 3,649 patients with hormone receptor–positive or –negative disease – who did not have diabetes – also found that metformin had no effect on survival.

These results “tell us that metformin is not effective against the most common types of breast cancer and any off-label use [of] this drug for the treatment of these common types of breast cancer should be stopped,” lead investigator and medical oncologist Pamela Goodwin, MD, a breast cancer researcher at the Lunenfeld-Tanenbaum Research Institute in Toronto, said in a press release.

The negative results “underscore the need for well-conducted randomized trials” before observational studies are put into practice, Dr. Goodwin and her team said.

However, the investigators cautioned against extrapolating their results to patients with diabetes, noting that “because metformin is effective in type 2 diabetes, the results ... should not affect the use of metformin” in breast cancer patients who have diabetes.

The study was published online in JAMA.

Patients were enrolled from 2010 to 2013 while undergoing adjuvant treatment – chemotherapy, radiotherapy, hormone therapy, and/or others – following complete resection of T1-3, N0-3 tumors. They were almost exclusively women (mean age, 52.4 years), and almost 90% were non-Hispanic White. They were primarily from the United States and Canada, with some patients from the United Kingdom and Switzerland.

Patients were randomly assigned equally to receive either metformin 850 mg twice daily or placebo for 5 years. Median follow-up was about 8 years.

Among 2,533 patients with estrogen receptor– and/or progesterone receptor–positive disease, the incidence of invasive disease–free survival events was 2.78 per 100 patient-years in the metformin group, vs. 2.74 per 100 patient-years in the placebo arm (hazard ratio [HR], 1.01, P = .93). There were 1.46 deaths per 100 patient-years with metformin, vs. 1.32 with placebo (HR, 1.10, P = .47).

Metformin was stopped early at about 3 years for the 1,116 hormone receptor–negative patients after futility was declared on interim analysis.

The first prospective study to evaluate the accuracy of a blood test for people being screened for colorectal cancer (CRC) revealed a high sensitivity and specificity.

At 90% specificity, the blood assay (Guardant Health) was 100% sensitive for detecting CRC. At 95% specificity, sensitivity was 88%.

The blood assay detects circulating tumor DNA from cancer in the bloodstream, which is then analyzed for multiple factors, including cancer genetics and methylation.

Lead author Paloma Peinado, MD, a medical oncologist at HM Hospitales, Madrid, and colleagues, called the results similar to those seen with noninvasive, stool-based testing, noting that the “sensitivity and specificity of the blood-based test reached clinically significant thresholds.”

“The reported performance, combined with a more acceptable mode of testing, suggests that this blood-based test may be a viable CRC screening option,” they added.

The study was presented at Digestive Disease Week^® (DDW) 2022, held virtually and in San Diego.

Dr. Peinado and colleagues studied 557 people who agreed to have blood drawn at the time of their colonoscopy. They enrolled participants at four hospitals in Spain.

One-third of participants (33%) who sought CRC screening were at average risk. Of the remainder, 49% were symptomatic, 11% had a positive family history of CRC, 6% had a positive stool-based test result, and 1% presented for colonoscopy for other reasons.

The prospective observational study included people age 45-84 years. The median age of participants was 55 years, and just over half (52%) were women.

The prevalence rate of colorectal adenocarcinoma was 2.6%. Eight patients had stage I cancer, three had stage II cancer, two had stage III cancer, and two had stage IV cancer.

The study was designed to follow patients for 1 year after screening. To date, 14% of participants have reached this point.

Not a general population screening study

“We definitely we need more studies like this,” said Barbara H. Jung, MD, chair of the department of medicine at the University of Washington, Seattle, when asked to comment on the study.

“We need to find other ways to detect colorectal cancer early, to enhance the screening, and to broaden it to a larger population who may not be amenable to the other techniques.”

Dr. Jung added a caveat that the study population included people at a higher risk for CRC. Therefore, she said, it was a screening study but not a general population, average-risk screening study.

However, she said, “that does not mean that this could not be optimized in the future.”  

Ideally, we need tests for every application, including people who are asymptomatic, Dr. Jung said.

Some smokers might not get lung cancer because of their DNA, researchers report in a new study.

These people have genes that help limit mutations to DNA that would turn cells malignant and make them grow into tumors, the researchers say.

Scientists have long suspected that smoking leads to lung cancer by triggering DNA mutations in healthy cells. But it was hard for them to identify the mutations in healthy cells that might help predict future cancer risk, Jan Vijg, PhD, a senior author of the study and researcher at the University School of Medicine, Shanghai, China, said in a statement.

His team used a process called single-cell whole genome sequencing to examine cells lining the lungs of 19 smokers and 14 nonsmokers ranging in age from their pre-teens to their mid-80s. The cells came from patients who had tissue samples collected from their lungs during diagnostic testing unrelated to cancer. The scientists reported their findings in Nature Genetics.

The researchers specifically looked at cells lining the lungs because these cells can survive for years and build up mutations over time that are linked to aging and smoking.

“Of all the lung’s cell types, these are among the most likely to become cancerous,” says Simon Spivack, MD, a senior author of the study and professor at the Albert Einstein College of Medicine, New York.

Smokers had far more gene mutations that can cause lung cancer than nonsmokers, the analysis found.

“This experimentally confirms that smoking increases lung cancer risk by increasing the frequency of mutations, as previously hypothesized,” says Dr. Spivack. “This is likely one reason why so few nonsmokers get lung cancer, while 10 to 20 percent of lifelong smokers do.”

Among the smokers, people had smoked a maximum of 116 pack-years. A pack-year is the equivalent of smoking one pack a day for a year. The number of mutations detected in smokers’ lung cells increased in direct proportion to the number of pack-years they smoked.

But after 23 pack-years, the lung cells in smokers didn’t appear to add more mutations, the researchers report, suggesting that some people’s genes might make them more likely to fight mutations.

“The heaviest smokers did not have the highest mutation burden,” says Dr. Spivack. “Our data suggest that these individuals may have survived for so long in spite of their heavy smoking because they managed to suppress further mutation accumulation.”

While it’s possible these findings could one day help doctors come up with better ways to screen for lung cancer and treat the disease, that’s still a long way off. Many more lab tests and larger studies will be needed to better pinpoint which smokers might be more prone to lung cancer and why.

In states that adopted Medicaid expansion following the implementation of the Affordable Care Act (ACA), patients with cancer have improved 2-year overall survival rates, compared with patients in states that did not adopt the expansion.

The finding comes from an American Cancer Society study of more than 2 million patients with newly diagnosed cancer, published online in the Journal of the National Cancer Institute.

The analysis also showed that the evidence was strongest for malignancies with poor prognosis such as lung, pancreatic, and liver cancer, and also for colorectal cancer.

Importantly, improvements in survival were larger in non-Hispanic Black patients and individuals residing in rural areas, suggesting there was a narrowing of disparities in cancer survival by race and rurality.

“Our findings provide further evidence of the importance of expanding Medicaid eligibility in all states, particularly considering the economic crisis and health care disruptions caused by the COVID-19 pandemic,” said lead author Xuesong Han, PhD, scientific director of health services research at the American Cancer Society, in a statement. “What’s encouraging is the American Rescue Plan Act of 2021 provides new incentives for Medicaid expansion in states that have yet to increase eligibility.”

The ACA provided states with incentives to expand Medicaid eligibility to all low-income adults under 138% federal poverty level, regardless of parental status.

As of last month, just 12 states have not yet opted for Medicaid expansion, even though the American Rescue Plan Act of 2021 provides new incentives for those remaining jurisdictions. But to date, none of the remaining states have taken advantage of these new incentives.

An interactive map showing the status of Medicare expansion by state is available here. The 12 states that have not adopted Medicare expansion (as of April) are Alabama, Florida, Georgia, Kansas, Mississippi, North Carolina, South Carolina, South Dakota, Tennessee, Texas, Wisconsin, and Wyoming.  

The benefit of Medicaid expansion on cancer outcomes has already been observed in other studies. The first study to show a survival benefit was presented at the 2020 American Society of Clinical Oncology annual meeting. That analysis showed that cancer mortality declined by 29% in states that expanded Medicaid and by 25% in those that did not. The authors also noted that the greatest mortality benefit was observed in Hispanic patients.
 

Improved survival with expansion

In the current paper, Dr. Han and colleagues used population-based cancer registries from 42 states and compared data on patients aged 18-62 years who were diagnosed with cancer in a period of 2 years before (2010-2012) and after (2014-2016) ACA Medicaid expansion. They were followed through Sept. 30, 2013, and Dec. 31, 2017, respectively.

The analysis involved a total of 2.5 million patients, of whom 1.52 million lived in states that adopted Medicaid expansion and compared with 1 million patients were in states that did not.

Patients with grouped by sex, race and ethnicity, census tract-level poverty, and rurality. The authors note that non-Hispanic Black patients and those from high poverty areas and nonmetropolitan areas were disproportionately represented in nonexpansion states. 

During the 2-year follow-up period, a total of 453,487 deaths occurred (257,950 in expansion states and 195,537 in nonexpansion states).

Overall, patients in expansion states generally had better survival versus those in nonexpansion states, the authors comment. However, for most cancer types, overall survival improved after the ACA for both groups of states.

The 2-year overall survival increased from 80.6% before the ACA to 82.2% post ACA in expansion states and from 78.7% to 80% in nonexpansion states.

This extrapolated to net increase of 0.44 percentage points in expansion states after adjusting for sociodemographic factors. By cancer site, the net increase was greater for colorectal cancer, lung cancer, non-Hodgkin’s lymphoma, pancreatic cancer, and liver cancer.

For Hispanic patients, 2-year survival also increased but was similar in expansion and nonexpansion states, and little net change was associated with Medicaid expansion.

“Our study shows that the increase was largely driven by improvements in survival for cancer types with poor prognosis, suggesting improved access to timely and effective treatments,” said Dr. Han. “It adds to accumulating evidence of the multiple benefits of Medicaid expansion.”

The analysis involved a total of 2.5 million patients, of whom 1.52 million lived in states that adopted Medicaid expansion and compared with 1 million patients were in states that did not.

Patients with grouped by sex, race and ethnicity, census tract-level poverty, and rurality. The authors note that non-Hispanic Black patients and those from high poverty areas and nonmetropolitan areas were disproportionately represented in nonexpansion states. 

During the 2-year follow-up period, a total of 453,487 deaths occurred (257,950 in expansion states and 195,537 in nonexpansion states).

Overall, patients in expansion states generally had better survival versus those in nonexpansion states, the authors comment. However, for most cancer types, overall survival improved after the ACA for both groups of states.

The 2-year overall survival increased from 80.6% before the ACA to 82.2% post ACA in expansion states and from 78.7% to 80% in nonexpansion states.

This extrapolated to net increase of 0.44 percentage points in expansion states after adjusting for sociodemographic factors. By cancer site, the net increase was greater for colorectal cancer, lung cancer, non-Hodgkin’s lymphoma, pancreatic cancer, and liver cancer.

For Hispanic patients, 2-year survival also increased but was similar in expansion and nonexpansion states, and little net change was associated with Medicaid expansion.

“Our study shows that the increase was largely driven by improvements in survival for cancer types with poor prognosis, suggesting improved access to timely and effective treatments,” said Dr. Han. “It adds to accumulating evidence of the multiple benefits of Medicaid expansion.”

Laparoscopic surgery can improve long-term overall survival (OS) compared with open surgery for patients with rectal cancer, according to findings from a large meta-analysis.

The estimated 5-year OS rate for patients who underwent laparoscopic surgery was 76.2%, vs. 72.7% for those who had open surgery.

“The survival benefit of laparoscopic surgery is encouraging and supports the routine use of laparoscopic surgery for adult patients with rectal cancer in the era of minimally invasive surgery,” wrote the authors, led by Leping Li, MD, of the department of gastrointestinal surgery, Shandong (China) Provincial Hospital.

The article was published online in JAMA Network Open.

Surgery is an essential component in treating rectal cancer, but the benefits of laparoscopic vs. open surgery are not clear. Over the past 15 years, randomized clinical trials (RCTs) have shown comparable long-term outcomes for laparoscopic and open surgery. However, in most meta-analyses that assessed the evidence more broadly, researchers used an “inappropriate” method for the pooled analysis. Dr. Li and colleagues wanted to perform their own meta-analysis to more definitively understand whether the evidence on long-term outcomes supports or opposes the use of laparoscopic surgery for rectal cancer.

In the current study, the authors conducted an individual participant data meta-analysis using time-to-event data and focused on the long-term survival outcomes after laparoscopic or open surgery for adult patients with rectal cancer.

Ten articles involving 12 RCTs and 3,709 participants were included. In these, 2,097 patients were randomly assigned to undergo laparoscopic surgery, and 1,612 were randomly assigned to undergo open surgery. The studies covered a global population, with participants from Europe, North America, and East Asia.

In a one-stage analysis, the authors found that disease-free survival was slightly better among patients who underwent laparoscopic surgery, but the results were statistically similar (hazard ratio [HR], 0.92; P = .26).

However, when it came to OS, those who had undergone laparoscopic surgery fared significantly better (HR, 0.85; P = .02).

These results held up in the two-stage analysis for both disease-free survival (HR, 0.92; P = .25) and OS (HR, 0.85; P = .02). A sensitivity analyses conducted with large RCTs yielded similar pooled effect sizes for disease-free survival (HR, 0.91; P = .20) and OS (HR, 0.84; P = .03).

The authors highlighted several reasons why laparoscopic surgery may be associated with better survival. First, the faster recovery from the minimally invasive procedure could allow patients to begin adjuvant therapy earlier. In addition, the reduced stress responses and higher levels of immune function among patients undergoing minimally invasive surgery may contribute to a long-term survival advantage.

“These findings address concerns regarding the effectiveness of laparoscopic surgery,” the authors wrote. However, “further studies are necessary to explore the specific mechanisms underlying the positive effect of laparoscopic surgery on OS.”

No outside funding source was noted. The authors have disclosed no relevant financial relationships.
