A simple, two-ingredient gel may boost the fighting power of a groundbreaking cancer treatment, say Stanford University engineers.

The gel – made from water and a plant-based polymer – delivers targeted T cells adjacent to a cancer growth, taking aim at solid tumors.

It’s the latest development in CAR T-cell therapy, a type of immunotherapy that involves collecting the patient’s T cells, reengineering them to be stronger, and returning them to the patient’s body.

Results have been promising in blood cancers, such as leukemia and lymphoma, but less so in solid tumors, such as brain, breast, or kidney cancer, according to the National Cancer Institute.

The gel “is a really exciting step forward,” says Abigail Grosskopf, a PhD candidate at Stanford (Calif.) University, who is the lead study author, “because it can change the delivery of these cells and expand this kind of treatment to other cancers.”
 

CAR T-cell therapy: Limits in solid tumors

Currently available CAR T-cell therapies are administered by intravenous infusion. But that doesn’t do much against tumors in specific locations because the cells enter the bloodstream and flow throughout the body. The cancer-fighting effort exhausts the T cells, weakening their ability to infiltrate dense tumors.

CAR T cells need cytokines to tell them when to attack, Ms. Grosskopf explains. If delivered through an IV drip, the number of cytokines required to destroy a solid tumor would be toxic to other, healthy parts of the body.

So Ms. Grosskopf and her colleagues created a hydrogel that can temporarily hold the T cells and cytokines and that can be injected near a tumor, bombarding the cancerous growth.

In their study, which was published in Science Advances, the injections wiped out mouse tumors in 12 days. The gel degraded harmlessly a few weeks later.
 

A “leaky pen” that fights cancer

The reason a gel works better than a liquid is because of its staying power, says Ms. Grosskopf, who compares the method to a leaky pen.

The gel acts as the “pen,” releasing activated CAR T cells at regular intervals to attack the cancerous growth. Whereas liquid dissipates quickly, the gel’s structure is strong enough to stay in place for weeks, Ms. Grosskopf says. Plus, it’s biocompatible and harmless within the body, she adds.

More preclinical studies are needed before human clinical trials can occur, Ms. Grosskopf says.

“Not only could this be a way to deliver T cells and cytokines,” Ms. Grosskopf says, “but it may be used for other targeted therapy cancer drugs that are in development. So we see this as running parallel to those efforts.”

Taking an even broader view, the gel could have applications across medical specialties, such as slow-release delivery of vaccines.

New research suggests that chemotherapy treatments for recurrent high-grade gliomas indicated by an assay-guided tool called ChemoID can boost median survival, compared with physician choice.

The randomized, phase 3 trial results were presented at the annual meeting of the American Association for Cancer Research.

Over a median follow-up of 9 months, median overall survival in the ChemoID group was 12.5 months (95% confidence interval, 10.2-14.7), compared with 9 months (95% CI, 4.2-13.8) in the group whose treatments were chosen by physicians (P = .010).

“While the prognosis is very dismal, we’re still providing a 3.5-month benefit in the guided arm versus physician choice,” said study coauthor Jagan Valluri, PhD, professor of cellular biology and integrative medicine at Marshall University, Huntington, W. Va.

As Dr. Valluri noted, patients with recurrent high-grade gliomas typically have failed radiation and are left with poor prognoses. Fewer than one in four patients respond to chemotherapy at this point, he said, and the response is inconsistent from patient to patient.

“We developed ChemoID since cancer is very unique,” he said, “and any kind of chemotherapy should be tailored to each individual patient on a case-by-case basis.”

The ChemoID tool, a proprietary assay, tests the response of patient cells to various chemotherapy treatments. A test costs $3,500, and some insurers cover it, Dr. Valluri said.

For the new study, researchers randomly assigned 50 patients with grade III/IV recurrent glioma to be treated with chemotherapy chosen by physicians or chemotherapy recommended by the ChemoID tool.

Risk of death in the ChemoID group was lower than in the physician-guided group (hazard ratio, 0.44; 95% CI, 0.24-0.81; P = .008), and median progression-free survival was higher in the ChemoID group (10.1 months vs. 3.5 months; 95% CI, 4.8-15.4 vs. 1.9-5.1; HR, 0.25; 95% CI, 0.14-0.44; P < .001).

“We want the treating physician to have actionable tools in front of them before they treat the patient,” Dr. Valluri said. “We want this assay to become mainstream and part of the standard care workup.”

The study is funded by Cordgenics, where Dr. Valluri serves as chief operating officer.

Clinicians are not following guidelines that recommend a de-escalation in surveillance for patients with low-risk non–muscle-invasive bladder cancer (NMIBC), a new study concludes.  

These cancers are associated with low rates of recurrence, progression, and bladder cancer–specific death, so current clinical practice guidelines recommend against frequent monitoring and testing.

However, the study authors found that patients with a low grade Ta NMIBC diagnosis underwent a median of three cystoscopies per year, and many also received a median of two imagine scans (CT or MRI) as well as 2-3 urine-based tests.

“These data suggest a need for ongoing efforts to limit overuse of treatment and surveillance, which may in turn mitigate associated increases in the costs of care,” write the authors, led by Kelly K. Bree, MD, from the department of urology, University of Texas MD Anderson Cancer Center, Houston. Bladder cancer has the highest lifetime treatment cost of all malignancies, they point out.

The study was published online in JAMA Network Open.
 

Higher value and more evidence-based

The impact of increased surveillance of this patient cohort has broad implications for patients and the health care system in general, say experts writing in an accompanying editorial.

“It has been well established that workup for NMIBC can have negative consequences for the physical and psychological health of patients,” note Grayden S. Cook, BS, and Jeffrey M. Howard, MD, PhD, both from University of Texas Southwestern Medical Center, Dallas.

“Many of these patients undergo frequent CT imaging of the urinary tract, which carries a high dose of radiation as well as the potential for financial toxic effects (that is, detrimental consequences to the patient because of health care costs),” they write.

Additionally, patient distress is a factor, as they may experience preprocedural anxiety, physical discomfort during procedures, and worry about disease progression, they point out.

“The impact of these patterns is substantial and may have negative consequences for both patients and the health care system,” they conclude. “Thus, it is imperative to move forward with initiatives that provide higher value and are more evidence-based and patient-centered.”
 

Study finds frequent surveillance

The American Urological Association (AUA)/Society of Urologic Oncologists (SUO), the European Association of Urology, and the International Bladder Cancer Group have made an effort to de-escalate surveillance and treatment for patients with low-grade Ta disease, while at the same time maintaining appropriate surveillance for high-grade aggressive disease.

However, the new study found that in practice, such patients undergo frequent testing.

The study involved 13,054 patients with low-grade Ta NMIBC. Most of the participants were male (73.5%), with a median age of 76 years, and had no or few comorbidities (71.2%).

Most patients had undergone cystoscopy, and rates increased over time: from 79.3% of patients in 2004 to 81.5% of patients in 2013 (P = .007). Patients underwent a median of 3.0 cystoscopies per year following their diagnosis, and upper-tract imaging was performed in most patients.

The use of kidney ultrasonography also rose from 19% of patients in 2004 to 23.2% in 2013, as did retrograde pyelography (20.9% in 2004 vs. 24.2% in 2013). Conversely, the use of intravenous pyelography declined (from 14.5% in 2004 to 1.7% in 2012), but there was an increase in CT and MRI in all years except 2010 (from 30.4% of patients in 2004 to 47% of patients in 2013; P < .001). The rate of urine-based testing also significantly increased during the study period (from 44.8% in 2004 to 54.9% in 2013; P < .001), with patients undergoing between two to three tests per year.

Adherence to current guidelines remained similar during the study time frame. For example, 55.2% of patients received two cystoscopies per year in 2004-2008, compared with 53.8% in 2009-2013 (P = .11), suggesting that there was an overuse of all surveillance testing modalities.

As for treatment, 17.2% received intravesical immunotherapy with bacillus Calmette-Guérin, 6.1% were treated with intravesical chemotherapy (excluding receipt of a single perioperative dose). Disease recurrence within this cohort was 1.7%, and only 0.4% experienced disease progression.

When looking at the cost, the total median expenditures at 1 year after diagnosis increased by 60% during the study period, from $34,792 in 2004 to $53,986 in 2013. Higher costs were seen among patients who experienced a recurrence versus no recurrence ($76,669 vs. $53,909).

The study was supported by a grant from the U.S. Department of Defense Peer Reviewed Cancer Research Program. Several of the authors have disclosed relationships with industry, as noted in the original article. Editorialists Mr. Cook and Dr. Howard have disclosed no relevant financial relationships.

Metformin use, regardless of dose, was associated with increased overall survival in older adults with advanced cancer, according to results of a retrospective study of patients with type 2 diabetes and stage IV cancer.

The analysis included 7,725 patients with lung, breast, colorectal, prostate, or pancreatic cancer identified through a search of a Surveillance, Epidemiology, and End Results (SEER)-Medicare dataset from 2007 to 2016.

Out of the full dataset, 2,981 patients (38.5%) had been prescribed metformin, and use was highest among patients with prostate cancer (46%).

Patients who took metformin versus those who did not had significantly better overall survival in both unadjusted (unadjusted hazard ratio [HR], 0.73; 95% confidence interval [CI], 0.69-0.76; P < .001) and adjusted models (adjusted HR, 0.77; 95% CI, 0.73-0.81; P < .001).

Lead author Lisa Scarton, PhD, RN, assistant professor, University of Florida College of Nursing, Gainesville, said that the “underlying mechanisms of metformin related to cancer are still not completely understood,” but many studies have shown metformin is associated with a reduction in the incidence of cancer, a reduction in cancer mortality, and an improvement in overall survival.

“As more evidence of anticancer benefit of metformin is emerging, it is important to explore optimal dosages that significantly improve cancer outcomes to boost anticancer effect,” she said in an interview.  

Dr. Scarton presented the new data in a poster at the annual meeting of the American Association for Cancer Research.  

The analysis found no significant difference in overall survival between patients who took metformin with average daily doses ≥ 1,000 mg or < 1,000 mg (aHR, 1.00; 95% CI, 0.93-1.08; P = .90).

Although the improvement in overall survival was seen in cancer subgroups, regardless of dose, Dr. Scarton noted the benefit was greatest among patients with breast cancer (aHR, 0.67; 95% CI, 0.56-0.82; P < .001). Hazard ratios among those who received metformin were 0.78 (95% CI, 0.69-0.88; P < .001) for colorectal cancer, 0.77 (95% CI, 0.72-0.82; P < .001) for lung cancer, 0.82 (95% CI, 0.72-0.93; P < .001) for pancreatic cancer, and 0.74 (95% CI, 0.62-0.88; P = .002) for prostate cancer. Also, she noted that race/ethnicity did not play a role as a significant factor for predicting better overall survival.

Among study limitations, Dr. Scarton said, was the advanced age of patients. “Our study population was 66 and older. It would be interesting to investigate this relationship among younger adults. We would also explore explicit benefits of metformin use in different racial and ethnic groups.”

The study was funded by the University of Florida. Dr. Scarton has reported no relevant financial relationships.

Globally, diagnoses and deaths from colorectal cancer (CRC) more than doubled over the past 30 years, according to a new analysis of 204 countries.

However, trends in CRC incidence and deaths varied by age, region, and sex. Investigators expressed particular concern over the rising incidence rates among people younger than 50 and those living in low and middle sociodemographic index countries in Asia and Africa.

“These results provide comprehensive and comparable estimates that can inform efforts for equitable colorectal cancer control worldwide,” the authors write. However, “further research is required to understand the causes of the colorectal cancer burden in younger adults (aged less than 50 years) and the main risk factors, including obesity, physical inactivity, alcohol consumption, smoking, and an altered gut microbiome, that might have led to the rise in the colorectal cancer burden.”

The study was published online in the Lancet Gastroenterology and Hepatology.

CRC is the third leading cause of cancer deaths worldwide, but data on incidence and mortality by location, age, and sex remain less clear.

In the current Global Burden of Diseases, Injuries and Risk Factors Study, researchers evaluated age, sex, and geography-level estimates of CRC incidence, deaths, and disability-adjusted life-years (DALYs) from 204 countries between 1990 and 2019.

The authors found that cases of CRC increased by almost 2.6-fold over the 30-year study period, from 842,098 to 2.17 million. Deaths from CRC increased at a similar but slightly lower rate – rising 2.1-fold over the same period, from 518,126 to 1.09 million. DALYs also nearly doubled, going from 12.4 million in 1990 to 24.3 million in 2019.

In addition, the global age-standardized incidence rate increased from 22.2 to 26.7 per 100,000.

Overall, the age-standardized mortality rate decreased slightly, from 14.3 to 13.7 per 100,000; however, only high-middle and high sociodemographic index regions experienced a decrease; low and middle sociodemographic index regions experienced an increase. The age-standardized DALY rate also declined overall, from 308.5 per 100,000 in 1900 to 295.5 per 100,000 in 2019.

The authors further broke down CRC incidence and deaths by age, region, and sex.

Over the study period, males demonstrated greater increases in CRC incidence, deaths, and DALYs, compared with females. In 2019, the age-standardized CRC incidence rate was 1.5 times higher in males (33.1 vs 21.2 per 100,000), as was the age-standardized mortality rate (16.6 vs. 11.2 per 100,000). The age-standardized DALY rate showed a similar trend by sex – 360 versus 238 per 100,000 in males versus females.

Trends varied by age as well. CRC incidence rates increased the most in people aged 85 and older, followed by those between 20 and 49 years, while rates decreased for those between 50 and 80 years in high sociodemographic index countries.

Geography mattered too. China, the United States, and Japan demonstrated the highest number of new CRC cases across all ages and for both sexes in 2019 – 607,900 in China, 227,242 in the United States, and 160,211 in Japan.

In terms of mortality, China, the United States, and India had the highest CRC death counts: 261,777 in China, 84,026 in the United States, and 79,098 in India.

When it comes to age-standardized incidence rates, Taiwan, Monaco, and Andorra were at the top: Taiwan with 62 per 100,000 cases, Monaco with 60.7 per 100,000, and Andorra with 56.6 per 100,000.

On the other hand, Somalia, Niger, and Bangladesh had the lowest age-standardized incidence rates, 5 per 100,000 in Somalia and 5.6 per 100,000 in Niger and Bangladesh.

The highest age-standardized mortality rates occurred in Greenland, Brunei, and Hungary: 31.4 per 100,000 in Greenland, 30.3 per 100,000 in Brunei, and 28.6 per 100,000 in Hungary.

The relative contribution of different risk factors also varied by region. For example, in sub-Saharan Africa and lower-income countries in Asia, diets low in calcium and milk were the main CRC risk factors. In contrast, smoking and alcohol consumption were the main risk factors driving CRC in high-income regions.

Still, the reasons underlying some of these trends – such as the increasing incidence of CRC in patients under the age of 50 – remain uncertain. One possible explanation for this trend, the researchers point out, is the birth cohort effect, which suggests that those born in the second half of the 20th century are increasingly exposed to potentially modifiable risk factors, such as an unhealthy diet, obesity, and sedentary lifestyles.

Overall, the authors note that the data generated in this study provide an important resource for both patients and oncologists about current trends in incidence and mortality and where gaps in preventive measures may exist.

In particular, the authors conclude that “public health interventions for colorectal cancer awareness, screening, and prevention through containment of modifiable risk factors such as alcohol, smoking, unhealthy diet ... and obesity are key to stemming the tide of colorectal cancer worldwide.”

The study was funded by the Bill & Melinda Gates Foundation. The authors have disclosed no relevant financial relationships.

Geography mattered too. China, the United States, and Japan demonstrated the highest number of new CRC cases across all ages and for both sexes in 2019 – 607,900 in China, 227,242 in the United States, and 160,211 in Japan.

In terms of mortality, China, the United States, and India had the highest CRC death counts: 261,777 in China, 84,026 in the United States, and 79,098 in India.

When it comes to age-standardized incidence rates, Taiwan, Monaco, and Andorra were at the top: Taiwan with 62 per 100,000 cases, Monaco with 60.7 per 100,000, and Andorra with 56.6 per 100,000.

On the other hand, Somalia, Niger, and Bangladesh had the lowest age-standardized incidence rates, 5 per 100,000 in Somalia and 5.6 per 100,000 in Niger and Bangladesh.

The highest age-standardized mortality rates occurred in Greenland, Brunei, and Hungary: 31.4 per 100,000 in Greenland, 30.3 per 100,000 in Brunei, and 28.6 per 100,000 in Hungary.

The relative contribution of different risk factors also varied by region. For example, in sub-Saharan Africa and lower-income countries in Asia, diets low in calcium and milk were the main CRC risk factors. In contrast, smoking and alcohol consumption were the main risk factors driving CRC in high-income regions.

Still, the reasons underlying some of these trends – such as the increasing incidence of CRC in patients under the age of 50 – remain uncertain. One possible explanation for this trend, the researchers point out, is the birth cohort effect, which suggests that those born in the second half of the 20th century are increasingly exposed to potentially modifiable risk factors, such as an unhealthy diet, obesity, and sedentary lifestyles.

Overall, the authors note that the data generated in this study provide an important resource for both patients and oncologists about current trends in incidence and mortality and where gaps in preventive measures may exist.

In particular, the authors conclude that “public health interventions for colorectal cancer awareness, screening, and prevention through containment of modifiable risk factors such as alcohol, smoking, unhealthy diet ... and obesity are key to stemming the tide of colorectal cancer worldwide.”

The study was funded by the Bill & Melinda Gates Foundation. The authors have disclosed no relevant financial relationships.

Vaccinated patients with cancer are more likely than those without cancer to contract a breakthrough COVID-19 infection, which puts them at a much higher risk for hospitalization and death, according to a study published in JAMA Oncology.

The risks were highest among patients who had certain cancers and those who had received cancer treatment within the past year.

“These results emphasize the need for patients with cancer to maintain mitigation practice, especially with the emergence of different virus variants and the waning immunity of vaccines,” the study authors wrote.

Researchers at Case Western Reserve University in Cleveland analyzed electronic health record data for more than 636,000 vaccinated patients, including more than 45,000 vaccinated patients with cancer. They looked for the time trends, risks, and outcomes of breakthrough COVID-19 infections for vaccinated cancer patients in the United States between December 2020 and November 2021.

Overall, the cumulative risk of breakthrough infections in vaccinated cancer patients was 13.6%, with the highest risk for pancreatic (24.7%), liver (22.8%), lung (20.4%), and colorectal (17.5%) cancers and the lowest risk for thyroid (10.3%), endometrial (11.9%), and breast (11.9%) cancers, versus 4.9% in vaccinated patients without cancer.

Patients who had medical encounters for their cancer within the past year had a higher risk for a breakthrough infection, particularly those with breast cancer, blood cancers, colorectal cancer, bladder cancer, and pancreatic cancer.

Among patients with cancer, the overall risk for hospitalization after a breakthrough infection was 31.6%, as compared with 3.9% in those without a breakthrough infection. In addition, the risk of death was 6.7% after a breakthrough infection, as compared with 1.3% in those without a breakthrough infection.

Among patients who didn’t have cancer, the overall hospitalization risk was 25.9% in patients with a breakthrough infection, as compared with 3% in those without a breakthrough infection. The overall risk of death was 2.7% after a breakthrough infection, as compared with 0.5% in those without a breakthrough infection.

In addition, breakthrough infections continuously increased for all patients from December 2020 to November 2021, with the numbers consistently higher among patients with cancer.

“This increasing time trend may reflect waning immunity of vaccines, the emergence of different virus variants, and varied measures taken by individuals and communities over time during the pandemic,” the study authors wrote.

Vaccines are likely less protective against coronavirus infection in cancer patients, and in turn, cancer patients may be more susceptible to COVID-19 infections, the researchers wrote. As breakthrough infections continue to increase for everyone, patients with cancer will face increased risks for severe breakthroughs, hospitalization, and death, they concluded.

BOSTON – Among dermatology residents and attending dermatologists, rates of diagnostic accuracy and appropriate biopsy recommendations were significantly lower for patients with skin of color, compared with White patients, new research shows.

“Our findings suggest diagnostic biases based on skin color exist in dermatology practice,” lead author Loren Krueger, MD, assistant professor in the department of dermatology, Emory University School of Medicine, Atlanta, said at the Annual Skin of Color Society Scientific Symposium. “A lower likelihood of biopsy of malignancy in darker skin types could contribute to disparities in cutaneous malignancies,” she added.

Dr. Loren Krueger

The findings underscore that “for skin of color patients, you’re more likely to have a benign neoplasm biopsied, you’re less likely to have a malignant neoplasm biopsied, and more often, your etiology may be missed,” Dr. Krueger said at the meeting.

Of note, while 45% of respondents were dermatology residents or fellows, 20.4% had 1-5 years of experience, and about 28% had 10 to more than 25 years of experience.

And while 75% of the dermatology residents, fellows, and attendings were White, there was no difference in the probability of correctly identifying the underlying etiology in dark or light skin types based on the provider’s self-identified race.

Importantly, the patterns in the study of diagnostic discrepancies are reflected in broader dermatologic outcomes. The 5-year melanoma survival rate is 74.1% among Black patients and 92.9% among White patients. Dr. Krueger referred to data showing that only 52.6% of Black patients have stage I melanoma at diagnosis, whereas among White patients, the rate is much higher, at 75.9%.

“We know skin malignancy can be more aggressive and late-stage in skin of color populations, leading to increased morbidity and later stage at initial diagnosis,” Dr. Krueger told this news organization. “We routinely attribute this to limited access to care and lack of awareness on skin malignancy. However, we have no evidence on how we, as dermatologists, may be playing a role.”

Furthermore, the decision to perform biopsy or not can affect the size and stage at diagnosis of a cutaneous malignancy, she noted.

Key changes needed to prevent the disparities – and their implications – should start at the training level, she emphasized. “I would love to see increased photo representation in training materials – this is a great place to start,” Dr. Krueger said.

In addition, “encouraging medical students, residents, and dermatologists to learn from skin of color experts is vital,” she said. “We should also provide hands-on experience and training with diverse patient populations.”

The first step to addressing biases “is to acknowledge they exist,” Dr. Krueger added. “I am hopeful this inspires others to continue to investigate these biases, as well as how we can eliminate them.”

The study was funded by the Rudin Resident Research Award. The authors have disclosed no relevant financial relationships.

In recent years, patients with advanced lung cancer have benefited from the advent of immune therapies and genotype-directed therapies –both of which have led to improved survival rates. But what will lung cancer look like in 2030?

Pasi A. Janne, MD, PhD, of the Dana-Farber Cancer Institute, Boston, hopes to see improved access to tumor and blood-based genotyping.

Dr. Janne, who serves as director of the Lowe Center for Thoracic Oncology at Dana-Farber, gave a keynote presentation at the 2022 European Lung Cancer Congress, where he highlighted the need to broaden the scope of targeted therapies, make “great drugs work even better,” improve the ability to treat patients based on risk level, and expand the use of targeted therapies in the adjuvant and neoadjuvant setting to make significant progress in the treatment lung cancer treatment in coming years.

Genotyping is underutilized, he said. A 2019 multicenter study reported at the annual meeting of the American Society of Clinical Oncology showed that only 54% of 1,203 patients underwent testing for EGFR mutations, 22% were tested for EGFR, ALK, ROS1, and BRAF mutations, and only 7% were tested for all biomarkers recommended by National Comprehensive Cancer Network guidelines at the time.

That study also showed that only 45% of patients received biomarker-driven treatment, even when driver mutations were detected.

“Immunotherapy was often prescribed instead of targeted therapy, even when molecular results were available,” Dr. Janne said.

Another study, reported at the 2021 ASCO annual meeting, showed some improvement in testing rates, but still, only 37% of patients were tested for all biomarkers as recommended.

Racial disparities in testing have also been observed. Bruno and colleagues found that any next-generation sequencing was performed in 50.1% of White patients, compared with 39.8% of black patients, and NGS prior to first-line therapy was performed in 35.5% and 25.8%, respectively.

The study, also reported at ASCO in 2021, showed that trial participation was observed among 3.9% of White patients and 1.9% of Black patients.

“The studies really highlight the need for increased testing rates and appropriate utilization of testing results to deliver optimal care to our patients with advanced lung cancer. We have a long way to go. To live the promise and appreciate the promise of precision therapy ... we need to be able to offer this testing to all of our patients with lung cancer,” he said.

Dr. Janne reported relationships with numerous pharmaceutical companies, including consulting, research support and stock ownership. He also receives postmarketing royalties from Dana-Farber Cancer Institute–owned intellectual property on EGFR mutations.

Pathological response has emerged as a valuable endpoint and surrogate marker for overall survival in lung cancer studies, but much work remains to be done, said William D. Travis, MD, director of thoracic pathology at Memorial Sloan Kettering Cancer Center, New York.

In a keynote address at the 2022 European Lung Cancer Conference, Dr. Travis highlighted advances in the use of pathological response in this setting and outlined areas that need refinement. “Pathologic response after preoperative therapy is important because the extent of pathologic response strongly correlates with improved overall survival, and it is reflective of neoadjuvant therapy. The degree of response is associated with the degree of benefit in survival, and it’s being used as a surrogate for survival in phase 2 and 3 neoadjuvant clinical trials.”

In fact, multiple studies have demonstrated that non–small cell lung cancer patients with 10% or less viable residual tumor after treatment have improved overall survival and disease-free survival, compared with patients who have more residual tumor, he explained.

Recent studies have demonstrated the value of pathological response as an endpoint in the neoadjuvant therapy and molecular targeted therapy setting, he said, citing a study published in the Journal of Clinical Oncology that showed major pathological response rates of 14%-45% and pathological complete response rates up to 29% in patients treated with single-agent checkpoint inhibition.

In the CheckMate 816 trial, both major pathologic response and pathological complete response were significantly higher in patients treated with combination nivolumab and chemotherapy, compared with those treated with chemotherapy alone (37% vs. 8.9% and 24% vs. 2%, respectively).

“This high rate of responses with combined immunotherapy and chemotherapy is quite exciting,” he said.

Dr. Travis also stressed the importance of consulting the current International Association for the Study of Lung Cancer Recommendations for Pathologic Assessment of Lung Cancer Resection Specimens After Neoadjuvant Therapy.

He highlighted several key points regarding pathological response in lung cancer:

• Major pathological response (MPR) is calculated as the estimated size of viable tumor divided by the size of the tumor bed.
• Optimal cutoffs for determining MPR is currently 10%, but recent data suggest that in the conventional chemotherapy setting this may vary by tumor histology, with much higher cutoffs of about 65% for adenocarcinoma.
• Estimating the amount of viable tumor is “quite complicated and requires quite a number of steps,” and one the most important steps is “for the surgeon to the pathologist know that given specimen is from a patient who received neoadjuvant therapy.”
• Determining the border of the tumor bed can be challenging, therefore “resection specimens after neoadjuvant therapy should be sampled to optimize comprehensive gross and histologic assessment of the lung tumor bed for pathologic response ... as outlined in the guidelines.”
• The IASLC panel determined that having a single approach for estimating treatment effect would be best, despite the different therapy types and combinations used, but “it is recognized that there may be certain types of features that need to be addressed,” such as immune cell infiltrates in pats who received immunotherapy.
• The recommendations provide specific guidance for measuring tumor size for staging, including for special circumstances.

As for future direction, Dr. Travis said, “one question is how to assess treatment effect in lymph node samples.

“This is done for lymph nodes in breast cancer but not in lung cancer. We need system[s] for lung cancer.”

Good “infrastructure for pathology departments” is needed to support clinical trials, he said, noting that the team at Memorial Sloan Kettering Cancer Center includes physician assistants, tissue procurement staff, frozen section techs, research fellows, and research assistants.

Future work should also aim to standardize pathology assessment for clinical trials, improve the current recommendations, make use of new technology like artificial intelligence, optimize banking protocols and special techniques, and identify radiologic-pathological correlations, he said.

He added that “IASLC is promoting the design and implementation of an international database to collect uniformly clinical and pathologic information with the ultimate goal of fostering collaboration and to facilitate the identification of surrogate endpoints of long-term survival.”

Dr. Travis is a nonpaid pathology consultant for the LCMC3 and LCMC4 trials.

Future work should also aim to standardize pathology assessment for clinical trials, improve the current recommendations, make use of new technology like artificial intelligence, optimize banking protocols and special techniques, and identify radiologic-pathological correlations, he said.

He added that “IASLC is promoting the design and implementation of an international database to collect uniformly clinical and pathologic information with the ultimate goal of fostering collaboration and to facilitate the identification of surrogate endpoints of long-term survival.”

Pathological response has emerged as a valuable endpoint and surrogate marker for overall survival in lung cancer studies, but much work remains to be done, said William D. Travis, MD, director of thoracic pathology at Memorial Sloan Kettering Cancer Center, New York.

In a keynote address at the 2022 European Lung Cancer Conference, Dr. Travis highlighted advances in the use of pathological response in this setting and outlined areas that need refinement. “Pathologic response after preoperative therapy is important because the extent of pathologic response strongly correlates with improved overall survival, and it is reflective of neoadjuvant therapy. The degree of response is associated with the degree of benefit in survival, and it’s being used as a surrogate for survival in phase 2 and 3 neoadjuvant clinical trials.”

In fact, multiple studies have demonstrated that non–small cell lung cancer patients with 10% or less viable residual tumor after treatment have improved overall survival and disease-free survival, compared with patients who have more residual tumor, he explained.

Recent studies have demonstrated the value of pathological response as an endpoint in the neoadjuvant therapy and molecular targeted therapy setting, he said, citing a study published in the Journal of Clinical Oncology that showed major pathological response rates of 14%-45% and pathological complete response rates up to 29% in patients treated with single-agent checkpoint inhibition.

In the CheckMate 816 trial, both major pathologic response and pathological complete response were significantly higher in patients treated with combination nivolumab and chemotherapy, compared with those treated with chemotherapy alone (37% vs. 8.9% and 24% vs. 2%, respectively).

“This high rate of responses with combined immunotherapy and chemotherapy is quite exciting,” he said.

Dr. Travis also stressed the importance of consulting the current International Association for the Study of Lung Cancer Recommendations for Pathologic Assessment of Lung Cancer Resection Specimens After Neoadjuvant Therapy.

He highlighted several key points regarding pathological response in lung cancer:

• Major pathological response (MPR) is calculated as the estimated size of viable tumor divided by the size of the tumor bed.
• Optimal cutoffs for determining MPR is currently 10%, but recent data suggest that in the conventional chemotherapy setting this may vary by tumor histology, with much higher cutoffs of about 65% for adenocarcinoma.
• Estimating the amount of viable tumor is “quite complicated and requires quite a number of steps,” and one the most important steps is “for the surgeon to the pathologist know that given specimen is from a patient who received neoadjuvant therapy.”
• Determining the border of the tumor bed can be challenging, therefore “resection specimens after neoadjuvant therapy should be sampled to optimize comprehensive gross and histologic assessment of the lung tumor bed for pathologic response ... as outlined in the guidelines.”
• The IASLC panel determined that having a single approach for estimating treatment effect would be best, despite the different therapy types and combinations used, but “it is recognized that there may be certain types of features that need to be addressed,” such as immune cell infiltrates in pats who received immunotherapy.
• The recommendations provide specific guidance for measuring tumor size for staging, including for special circumstances.

As for future direction, Dr. Travis said, “one question is how to assess treatment effect in lymph node samples.

“This is done for lymph nodes in breast cancer but not in lung cancer. We need system[s] for lung cancer.”
