The incorporation of medical scribes into an outpatient oncology setting may lower physician burnout and improve patient care, according to a retrospective study.

“The objective of this study was to determine the effect of scribe integration on clinic workflow efficiency and physician satisfaction and quality of life in outpatient oncology clinics,” wrote Rebecca W. Gao, MD, of Stanford (Calif.) Medicine, and colleagues in the Journal of Oncology Practice.

The researchers retrospectively analyzed patient and survey data from 129 physicians connected with a tertiary care academic medical center during 2017-2019. In the study, 33 physicians were paired with a scribe, while 96 others were not.

During each patient encounter, visit duration times were recorded into an electronic medical record by a medical scribe. The scribes also performed a variety of other tasks, including collating lab results, documenting medical history, and completing postvisit summaries.

In the analysis, the team compared average visit duration times between physicians with and without a scribe. The effects of scribe integration on individual physician’s visit times were also assessed.

After analysis, the researchers found that physicians with a scribe experienced a 12.1% reduction in overall average patient visit duration, compared with visit times before scribe integration (P less than .0001). They also reported that less time was spent charting at the end of the day (P = .04).

“Compared with their peers, oncologists with scribes showed a 10%-20% decrease in the duration of all patient visits,” they explained.

With respect to patient care, survey results revealed that 90% of physicians strongly agreed they spent additional time with patients, and less time at the computer. “100% of physicians surveyed ‘strongly agreed’ that scribes improved their quality of life,” they added.

The researchers acknowledged that a key limitation of the study was the single-center design. As a result, these findings may not be applicable to physicians practicing in community-based settings.

Further studies could include financial analyses to evaluate the cost-effectiveness of medical scribe use in oncology practices, they noted.

“Our study suggests that scribes can be successfully integrated into oncology clinics and may benefit physician quality of life, clinic workflow efficiency, and the quality of physician-patient interactions,” they concluded.

The study was funded by the Stanford Cancer Center. One study author reported financial affiliations with SurgVision, Vergent Biotechnology, Novadaq Technologies, and LI-COR Biosciences.

A combination of the tyrosine kinase inhibitor lenvatinib (Lenvima) and the immune checkpoint inhibitor pembrolizumab (Keytruda) was safe and showed promising activity against advanced renal cell carcinoma and other solid tumors in a phase 1b/2 study.

Overall response rates (ORR) at 24 weeks ranged from 63% for patients with advanced renal cell carcinomas (RCC) to 25% for patients with urothelial cancers, reported Matthew H. Taylor, MD, of Knight Cancer Institute at Oregon Health & Science University in Portland, and colleagues.

The findings from this study sparked additional clinical trials for patients with gastric cancer, gastroesophageal cancer, and differentiated thyroid cancer, and set the stage for larger phase 3 trials in patients with advanced RCC, endometrial cancer, malignant melanoma, and non–small cell lung cancer (NSCLC).

“In the future, we also plan to study lenvatinib plus pembrolizumab in patients with RCC who have had disease progression after treatment with immune checkpoint inhibitors,” they wrote. The report was published in Journal of Clinical Oncology.

Lenvatinib is a multitargeted tyrosine kinase inhibitor (TKI) with action against vascular endothelial growth factor (VEGF) receptors 1-3, fibroblast growth factor (FGF) receptors 1-4, platelet-derived growth factor receptors alpha and the RET and KIT kinases.

“Preclinical and clinical studies suggest that modulation of VEGF-mediated immune suppression via angiogenesis inhibition could potentially augment the immunotherapeutic activity of immune checkpoint inhibitors,” the investigators wrote.

They reported results from the dose finding (1b) phase including 13 patients and initial phase 2 expansion cohorts with a total of 124 patients.

The maximum tolerated dose of lenvatinib in combination with pembrolizumab was established as 20 mg/day.

At 24 weeks of follow-up, the ORR for 30 patients with RCC was 63%; two additional patients had responses after week 24, for a total ORR at study cutoff in this cohort of 70%. The median duration of response for these patients was 20 months, and the median progression-free survival (PFS) was 19.8 months. At the time of data cutoff for this analysis, 9 of the 30 patients with RCC were still on treatment.

For 23 patients with endometrial cancer, the 24-week and overall ORR were 52%, with a median duration of response not reached, and a median PFS of 9.7 months. Seven patients were still on treatment at data cutoff.

For 21 patients with melanoma, the 24-week and overall ORR were 48%, median duration of response was 12.5 months, and median PFS was 5.5 months. Two of the patients were still on treatment at data cutoff.

For the 22 patients with squamous cell cancer of the head and neck, the 24-week ORR was 36%, with two patients having a response after week 24 for a total ORR at data cutoff of 46%. The median duration of response was 8.2 months and the median PFS was 4.7 months. Three patients remained on treatment at data cutoff.

For 21 patients with NSCLC, the 24-week and overall ORR were 33%, the median duration of response was 10.9 months, and median PFS was 5.9 months. Six of the patients were still receiving treatment at data cutoff.

For 20 patients with urothelial cancer, the 24-week and overall ORR were 25%, with a median duration of response not reached, and a median PFS of 5.4 months. Three patients were still receiving the combination at the time of data cutoff.

Treatment related adverse events (TRAEs) occurred in 133 of all 137 patients enrolled in the two study phases. The adverse events were similar across all cohorts, with any grade of events including fatigue in 58%, diarrhea in 52%, hypertension in 47%, hypothyroidism in 42%, and decreased appetite in 39%.

The most frequent grade 3 or 4 TRAEs were hypertension in 20%, fatigue in 12%, diarrhea in 9%, proteinuria in 8%, and increased lipase levels in 7%.

In all, 85% of patients had a TRAE leading to lenvatinib dose reduction and/or interruption, and 13% required lenvatinib discontinuation.

Events leading to pembrolizumab dose interruption occurred in 45% of patients, and pembrolizumab discontinuation in 15%.

The study was sponsored by Eisai with collaboration from Merck Sharp & Dohme. Dr. Taylor disclosed a consulting or advisory role for Bristol-Myers Squibb, Eisai, Array BioPharma, Loxo, Bayer, ArQule, Blueprint Medicines, Novartis, and Sanofi/Genzyme, and speakers bureau activities for BMS and Eisai.

CT scan screening of older people with heavy smoking histories – using lesion volume, not diameter, as a trigger for further work-up – reduced lung cancer deaths by about 30% in a randomized trial from the Netherlands and Belgium with almost 16,000 current and former smokers, investigators reported in the New England Journal of Medicine.

The Dutch-Belgian lung-cancer screening trial (Nederlands-Leuvens Longkanker Screenings Onderzoek [NELSON]) is “arguably the only adequately powered trial other than the” National Lung Screening Trial (NLST) in the United States to assess the role of CT scan screening among smokers, wrote University of London cancer epidemiologist Stephen Duffy, MSc, and University of Liverpool molecular oncology professor John Field, PhD, in an accompanying editorial.

NLST, which used lesion diameter, found an approximately 20% lower lung cancer mortality than screening with chest x-rays among 53,454 heavy smokers after a median follow-up of 6.5 years. The trial ultimately led the U.S. Preventive Services Task Force to recommend annual screening for people aged 55-80 years with a history of at least 30 pack-years.

European countries have considered similar programs but have hesitated “partly due to doubts fostered by the early publication of inconclusive results of a number of smaller trials in Europe. These doubts should be laid to rest,” Mr. Duffy and Dr. Field wrote.

“With the NELSON results, the efficacy of low-dose CT screening for lung cancer is confirmed. Our job is no longer to assess whether low-dose CT screening for lung cancer works; it does. Our job is to identify the target population in which it will be acceptable and cost effective,” they added.

The 15,789 NELSON participants (84% men, with a median age of 58 years and 38 pack-year history) were randomized about 1:1 to either low-dose CT scan screening at baseline and 1, 3, and 5.5 years, or to no screening.

At 10 years follow-up, there were 5.58 lung cancer cases and 2.5 deaths per 1,000 person-years in the screened group versus 4.91 cases and 3.3 deaths per 1,000 person-years among controls. Lung-cancer mortality was 24% lower among screened subjects overall, and 33% lower among screened women. The team estimated that screening prevented about 60 lung cancer deaths.

Using volume instead of diameter “resulted in low[er] referral rates” – 2.1% with a positive predictive value of 43.5% versus 24% with a positive predictive value of 3.8% in NLST – for additional work-up, explained investigators led by H.J. de Koning, MD, PhD, of the department of public health at Erasmus University Medical Center in Rotterdam, the Netherlands.

The upper limit of overdiagnosis risk – a major concern with any screening program – was 18.5% with NLST versus 8.9% with NELSON, they wrote.

In short: “Volume CT screening enabled a significant reduction of harms (e.g., false positive tests and unnecessary work-up procedures) without jeopardizing favorable outcomes,” the investigators wrote. Indeed, an ad hoc analysis suggested “more-favorable effects on lung-cancer mortality than in the NLST, despite lower referral rates for suspicious lesions” and the fact that NLST used annual screening.

“Recently,” Mr. Duffy and Dr. Field explained in their editorial, “the NELSON investigators evaluated both diameter and volume measurement to estimate lung-nodule size as an imaging biomarker for nodule management; this provided evidence that using mean or maximum axial diameter to assess nodule volume led to a substantial overestimation of nodule volume.” Direct measurement of volume “resulted in a substantial number of early-stage cancers identified at the time of diagnosis and avoided false positives from the overestimation incurred by management based on diameter.”

“The lung-nodule management system used in the NELSON trial has been advocated in the European position statement on lung-cancer screening. This will improve the acceptability of the intervention, because the rate of further investigation has been a major concern in lung cancer screening,” they wrote.

Baseline characteristics did not differ significantly between the screened and unscreened in NELSON, except for a slightly longer duration of smoking in the screened group.

The work was funded by the Netherlands Organization of Health Research and Development, among others. Mr. Duffy and Dr. de Koning didn’t report any disclosures. Dr. Field is an advisor for AstraZeneca, Epigenomics, and Nucleix, and has a research grant to his university from Janssen.

“Recently,” Mr. Duffy and Dr. Field explained in their editorial, “the NELSON investigators evaluated both diameter and volume measurement to estimate lung-nodule size as an imaging biomarker for nodule management; this provided evidence that using mean or maximum axial diameter to assess nodule volume led to a substantial overestimation of nodule volume.” Direct measurement of volume “resulted in a substantial number of early-stage cancers identified at the time of diagnosis and avoided false positives from the overestimation incurred by management based on diameter.”

“The lung-nodule management system used in the NELSON trial has been advocated in the European position statement on lung-cancer screening. This will improve the acceptability of the intervention, because the rate of further investigation has been a major concern in lung cancer screening,” they wrote.

Baseline characteristics did not differ significantly between the screened and unscreened in NELSON, except for a slightly longer duration of smoking in the screened group.

The work was funded by the Netherlands Organization of Health Research and Development, among others. Mr. Duffy and Dr. de Koning didn’t report any disclosures. Dr. Field is an advisor for AstraZeneca, Epigenomics, and Nucleix, and has a research grant to his university from Janssen.

SAN FRANCISCO – Young adults with colorectal cancer who live in neighborhoods with higher levels of disadvantage differ on health measures, present with more advanced disease, and have poorer survival. These were among key findings of a retrospective cohort study reported at the 2020 GI Cancers Symposium.

MDedge/Susan London

The incidence of colorectal cancer has risen sharply – 51% – since 1994 among individuals aged younger than age 50 years, with the greatest uptick seen among those aged 20-29 years (J Natl Cancer Inst. 2017;109[8]. doi: 10.1093/jnci/djw322).

“Sociodemographic disparities have been linked to inferior survival. However, their impact and association with outcome in young adults is not well described,” said lead investigator Ashley Matusz-Fisher, MD, of the Levine Cancer Institute in Charlotte, N.C.

The investigators analyzed data from the National Cancer Database for the years 2004-2016, identifying 26,768 patients who received a colorectal cancer diagnosis when aged 18-40 years.

Results showed that those living in areas with low income (less than $38,000 annually) and low educational attainment (high school graduation rate less than 79%), and those living in urban or rural areas (versus metropolitan areas) had 24% and 10% higher risks of death, respectively.

Patients in the low-income, low-education group were more than six times as likely to be black and to lack private health insurance, had greater comorbidity, had larger tumors and more nodal involvement at diagnosis, and were less likely to undergo surgery.

Several factors may be at play for the low-income, low-education group, Dr. Matusz-Fisher speculated: limited access to care, lack of awareness of important symptoms, and inability to afford treatment when it is needed. “That could very well be contributing to them presenting at later stages and then maybe not getting the treatment that other people who have insurance would be getting.

“To try to eliminate these disparities, the first step is recognition, which is what we are doing – recognizing there are disparities – and then making people aware of these disparities,” she commented. “More efforts are needed to increase access and remove barriers to care, with the hope of eliminating disparities and achieving health equity.”

Mitigating disparities

Several studies have looked at mitigating sociodemographic-related disparities in colorectal cancer outcomes, according to session cochair John M. Carethers, MD, AGAF, professor and chair of the department of internal medicine at the University of Michigan, Ann Arbor.

A large Delaware initiative tackled the problem via screening (J Clin Oncol. 2013;31:1928-30). “Now this was over 50 – we don’t typically screen under 50 – but over 50, you can essentially eliminate this disparity with navigation services and screening. How do you do that under 50? I’m not quite sure,” he said in an interview, adding that some organizations are recommending lowering the screening age to 45 or even 40 years in light of rising incidence among young adults.

However, accumulating evidence suggests that there may be inherent biological differences that are harder to overcome. “There is a lot of data … showing that polyps happen earlier and they are bigger in certain racial groups, particularly African Americans and American Indians,” Dr. Carethers elaborated. What is driving the biology is unknown, but the microbiome has come under scrutiny.

“So you are a victim of your circumstances,” he summarized. “You are living in a low-income area, you are eating more proinflammatory-type foods, you are getting your polyps earlier, and then you are getting your cancers earlier.”

Study details

Rural, urban, or metropolitan status was ascertained for 25,861 patients in the study, and area income and education were ascertained for 7,743 patients, according to data reported at the symposium, sponsored by the American Gastroenterological Association, the American Society of Clinical Oncology, the American Society for Radiation Oncology, and the Society of Surgical Oncology.

Compared with counterparts living in areas with both high annual income (greater than $68,000) and education (greater than 93% high school graduation rate), patients living in areas with both low annual income (less than $38,000) and education ( less than 79% high school graduation rate) were significantly more likely to be black (odds ratio, 6.4), not have private insurance (odds ratio, 6.3), have pathologic T3/T4 stage (OR, 1.4), have positive nodes (OR, 1.2), and have a Charlson-Deyo comorbidity score of 1 or greater (OR, 1.6). They also were less likely to undergo surgery (OR, 0.63) and more likely to be rehospitalized within 30 days (OR, 1.3).

After adjusting for race, insurance status, T/N stage, and comorbidity score, relative to counterparts in the high-income, high-education group, patients in the low-income, low-education group had an increased risk of death (hazard ratio, 1.24; P = .004). And relative to counterparts living in metropolitan areas, patients living in urban or rural areas had an increased risk of death (HR, 1.10; P = .02).

Among patients with stage IV disease, median overall survival was 26.1 months for those from high-income, high-education areas, but 20.7 months for those from low-income, low-education areas (P less than .001).

Dr. Matusz-Fisher did not report any conflicts of interest. The study did not receive any funding.

A new and simple nomogram for predicting the risk of bladder cancer in patients with microscopic hematuria could optimize the diagnostic work up process, according to a recent study.

The tool may help improve patient understanding about their risk of bladder cancer, as well as alleviate unnecessary diagnostic evaluations for some patients.

“The goal of this study was to identify objective clinical factors associated with a bladder cancer diagnosis and to use these factors to create a nomogram that accurately predicts risk of bladder cancer,” wrote Richard S. Matulewicz, MD, MS, of Northwestern University, Chicago, and colleagues in Urologic Oncology.

Researchers identified 4,178 patients with a new diagnosis of microscopic hematuria from 2007 to 2015. Data was collected from an enterprise data repository of the Northwestern Medicine healthcare system. Study participants who underwent a full microhematuria evaluation were randomized to either a training or validation subgroup. In the training cohort, logistic regression analysis was used to detect factors linked to the diagnosis of bladder cancer. In the model, receiver operating curves were built to predict a diagnosis of bladder cancer among participants. In addition, calibration plots were computed for both subgroups to evaluate the discriminative ability of the model. After analysis, the researchers found significant differences in urinalysis results and demographics among patients with and without a diagnosis of bladder cancer. Patients with bladder cancer had a higher amount of microhematuria (RBC/hpf) on urinalysis (P less than .0001), were more likely previous or current smokers (P = .001), were more often male (68.2% vs. 49.7%; P = .0002), and were older (69.1 vs. 58.2 years; P less than .0001).

With respect to the predictive ability of the model, the area under the curve (AUC) in the training and validation set was 0.79 (95% confidence interval, 0.75-0.83) and 0.74 (95% CI, 0.67-0.80), respectively.

In addition, calibration plots demonstrated that the tool was able to predict the risk of bladder cancer diagnosis for patients with a probability of 0.3 or below.

“These results indicate that the model works best for a range of probabilities of (0-0.30), which is the vast majority of patients clinically and in our data,” the researchers explained.

The team acknowledged that characterizing risk beyond these levels should be done with caution given poor calibration beyond this threshold.

“External validation [of the model] and continued evolution of risk stratification models are needed,” they concluded.

The study was funded by the National Institutes of Health and the American Association of Medical Colleges. The authors reported having no conflicts of interest.

ORLANDO – There’s now mature data surrounding the use of chimeric antigen receptor (CAR) T-cell therapy in lymphoma, and the annual meeting of the American Society of Hematology brought forth additional information from real-world studies, insights about what is driving relapse, and promising data on mantle cell lymphoma.

Vidyard Video

During a video roundtable at the meeting, experts discussed some of the CAR T-cell studies presented at ASH and what those findings mean in practice. The roundtable participants included Brian Hill, MD, of the Cleveland Clinic Taussig Cancer Center; Frederick L. Locke, MD, of the Moffit Cancer Center in Tampa, Fla.; and Peter Riedell, MD, of the University of Chicago.

Among the studies highlighted by the panel was the Transcend NHL 001 study (Abstract 241), which looked at third-line use of lisocabtagene maraleucel (liso-cel) in patients with diffuse large B-cell lymphoma, transformed follicular lymphoma, and other indolent non-Hodgkin lymphoma subtypes. More than 300 patients were enrolled, and liso-cel met all primary and secondary efficacy endpoints, with an overall response rate of more than 70%. The notable take-home point from the study was the safety profile, Dr. Riedell noted. Liso-cel was associated with a lower rate of cytokine release syndrome and neurologic toxicity, compared with the currently approved products.

Since patients in the study had a lower incidence and later onset of cytokine release syndrome, liso-cel could be a candidate for outpatient administration, Dr. Locke said. However, doing that would require “significant infrastructure” in hospitals and clinics to properly support patients, especially given that the treatment-related mortality on the study was similar to approved CAR T-cell products at about 3%. “You have to be ready to admit the patient to the hospital very rapidly, and you have to have the providers and the nurses who are vigilant when the patient is not in the hospital,” he said.

Another notable study presented at ASH examined the characteristics and outcomes of patients receiving bridging therapy while awaiting treatment with axicabtagene ciloleucel (Abstract 245). This real-world study adds interesting information to the field because, in some of the studies that were pivotal to the approval of CAR T-cell therapy, bridging therapy was not allowed, Dr. Locke said.

In this analysis, researchers found that the overall survival was worse among patients who received bridging. This finding suggests that patients who received bridging therapy had a different biology or that the therapy itself may have had an effect on the host or tumor microenvironment that affected the efficacy of the CAR T-cell therapy, the researchers reported.

The panel also highlighted the Zuma-2 study, which looked at KTE-X19, an anti-CD19 CAR T-cell therapy, among more than 70 patients with relapsed/refractory mantle cell lymphoma who had failed treatment with a Bruton’s tyrosine kinase inhibitor (Abstract 754). “This was, I thought, kind of a sleeper study at ASH,” said Dr. Hill, who was one of the authors of the study.

The overall response rate was 93% with about two-thirds of patients achieving a complete response. Researchers found that the response was consistent across subgroups, including Ki-67 and patients with prior use of steroids or bridging therapy. Dr. Locke, who was also a study author, said the results are a “game changer.”

“I’m very excited about it,” Dr. Riedell said, noting that these are patients without a lot of treatment options.

The panel also discussed other studies from ASH, including an analysis of tumor tissue samples from patients in the ZUMA-1 trial who had responded and subsequently relapsed (Abstract 203); a multicenter prospective analysis of circulating tumor DNA in diffuse large B-cell lymphoma patients who had relapsed after treatment with axicabtagene ciloleucel (Abstract 884); and the early use of corticosteroids to prevent toxicities in patients in cohort 4 of the ZUMA-1 trial (Abstract 243).

Dr. Hill reported consulting with Juno/Celgene/BMS and Novartis and research and consulting for Kite/Gilead. Dr. Locke reported consulting for Cellular Biomedicine Group and being a scientific adviser to Kite/Gilead, Novartis, Celgene/BMS, GammaDelta Therapeutics, Calibr, and Allogene. Dr. Riedell reported consulting for Bayer and Verastem, consulting for and research funding from Novartis and BMS/Celgene, and consulting for, research funding from, and speaking for Kite.

ORLANDO – There’s now mature data surrounding the use of chimeric antigen receptor (CAR) T-cell therapy in lymphoma, and the annual meeting of the American Society of Hematology brought forth additional information from real-world studies, insights about what is driving relapse, and promising data on mantle cell lymphoma.

During a video roundtable at the meeting, experts discussed some of the CAR T-cell studies presented at ASH and what those findings mean in practice. The roundtable participants included Brian Hill, MD, of the Cleveland Clinic Taussig Cancer Center; Frederick L. Locke, MD, of the Moffit Cancer Center in Tampa, Fla.; and Peter Riedell, MD, of the University of Chicago.

Among the studies highlighted by the panel was the Transcend NHL 001 study (Abstract 241), which looked at third-line use of lisocabtagene maraleucel (liso-cel) in patients with diffuse large B-cell lymphoma, transformed follicular lymphoma, and other indolent non-Hodgkin lymphoma subtypes. More than 300 patients were enrolled, and liso-cel met all primary and secondary efficacy endpoints, with an overall response rate of more than 70%. The notable take-home point from the study was the safety profile, Dr. Riedell noted. Liso-cel was associated with a lower rate of cytokine release syndrome and neurologic toxicity, compared with the currently approved products.

Since patients in the study had a lower incidence and later onset of cytokine release syndrome, liso-cel could be a candidate for outpatient administration, Dr. Locke said. However, doing that would require “significant infrastructure” in hospitals and clinics to properly support patients, especially given that the treatment-related mortality on the study was similar to approved CAR T-cell products at about 3%. “You have to be ready to admit the patient to the hospital very rapidly, and you have to have the providers and the nurses who are vigilant when the patient is not in the hospital,” he said.

Another notable study presented at ASH examined the characteristics and outcomes of patients receiving bridging therapy while awaiting treatment with axicabtagene ciloleucel (Abstract 245). This real-world study adds interesting information to the field because, in some of the studies that were pivotal to the approval of CAR T-cell therapy, bridging therapy was not allowed, Dr. Locke said.

In this analysis, researchers found that the overall survival was worse among patients who received bridging. This finding suggests that patients who received bridging therapy had a different biology or that the therapy itself may have had an effect on the host or tumor microenvironment that affected the efficacy of the CAR T-cell therapy, the researchers reported.

The panel also highlighted the Zuma-2 study, which looked at KTE-X19, an anti-CD19 CAR T-cell therapy, among more than 70 patients with relapsed/refractory mantle cell lymphoma who had failed treatment with a Bruton’s tyrosine kinase inhibitor (Abstract 754). “This was, I thought, kind of a sleeper study at ASH,” said Dr. Hill, who was one of the authors of the study.

The overall response rate was 93% with about two-thirds of patients achieving a complete response. Researchers found that the response was consistent across subgroups, including Ki-67 and patients with prior use of steroids or bridging therapy. Dr. Locke, who was also a study author, said the results are a “game changer.”

“I’m very excited about it,” Dr. Riedell said, noting that these are patients without a lot of treatment options.

Chimeric antigen receptor (CAR) T-cell therapy is generally associated with good long-term neuropsychiatric status, based on a recent patient-reported outcomes study.

But almost one out of five patients may have notably worse cognitive and psychiatric outcomes within 1-5 years of therapy, reported Julia Ruark, MD, of the University of Washington, Seattle, and colleagues. According to Dr. Ruark and associates, this latter finding suggests that CAR T-cell therapy may negatively impact mental health in a subset of patients.

These findings provide clinical insight into a minimally researched patient population.

“At this time, only limited data are available regarding the long-term effects of CAR T-cell therapy,” the investigators wrote in Biology of Blood and Marrow Transplantation. “Thus, it is important to evaluate the late neuropsychiatric effects of CAR T and evaluate their effect on survivors’ quality of life.”

The study involved 40 patients with relapsed or refractory chronic lymphocytic leukemia, non-Hodgkin lymphoma, or acute lymphoblastic leukemia. Before undergoing CAR T-cell therapy, patients underwent standardized mental health screening with validated instruments such as the 7-item Generalized Anxiety Disorder scale. At least 1 year after CAR T-cell therapy, patients completed a questionnaire consisting of the Patient-Reported Outcomes Measurement Information System (PROMIS) Scale v1.2 Global Health and the PROMIS-29 Profile v2.1, and 30 additional questions, 4 of which evaluated cognitive function. These data were converted to T scores for comparative purposes.

Patients who underwent CAR T-cell therapy had statistically similar T scores to the general population mean, suggesting comparable overall neuropsychiatric status. However, a closer look at the data showed that almost one out of five patients who underwent CAR T-cell therapy had global mental health scores that were at least 1 standard deviation lower than the mean for the general population and patients with cancer.

Almost half of the patients (47.5%) who underwent CAR T-cell therapy reported at least one clinically meaningful negative neuropsychiatric outcome. Specifically, 20% reported cognitive difficulties and depression or anxiety, 17.5% reported cognitive difficulties without depression or anxiety, and 10% reported depression or anxiety without cognitive difficulties. One-quarter (25%) of patients reported taking a medication for depression, 20% reported use of anxiolytics, and 15% reported use of sleep medications. Multivariate analysis revealed an association between younger age and depression (P = .01), anxiety (P = .001), and worse long-term global mental health (P = .02). Cognitive difficulties were significantly more common among patients with worse physical and/or mental health.

“[A] subset of patients may experience psychiatric symptoms or cognitive impairment [which may be related to CAR T-cell therapy or other treatments patients have been exposed to], and it is important to identify those patients to assist with intervention strategies,” the investigators concluded.The study was funded by the National Institutes of Health, Life Science Discovery Fund, Juno Therapeutics/Celgene, and others. The investigators reported additional relationships with Nektar Therapeutics, Allogene Therapeutics, T-CURX, and others.

Declines in death rates for lung cancer and melanoma have gained momentum in recent years, fueling a record drop in cancer mortality, the American Cancer Society says.

Lung cancer death rates, which were falling by 3% in men and 2% in women annually in 2008 through 2013, dropped by 5% in men and nearly 4% per year in women annually from 2013 to 2017, according to the society’s 2020 statistical report.

Those accelerating reductions in death rates helped fuel the biggest-ever single year decline in overall cancer mortality, of 2.2%, from 2016 to 2017, their report shows.

According to the investigators, the decline in melanoma death rates escalated to 6.9% per year among 20- to 49-year-olds over 2013-2017, compared with a decline of just 2.9% per year during 2006-2010. Likewise, the melanoma death rate decline was 7.2% annually for the more recent time period, compared with just 1.3% annually in the earlier time period. The finding was even more remarkable for those 65 years of age and older, according to investigators, since the declines in melanoma death rates reached 6.2% annually, compared with a 0.9% annual increase in the years before immunotherapy.

Smoking cessation has been the main driver of progress in cutting lung cancer death rates, according to the report, while in melanoma, death rates have dropped after the introduction of immune checkpoint inhibitors and targeted therapies.

By contrast, reductions in death rates have slowed for colorectal cancers and female breast cancers, and have stabilized for prostate cancer, Ms. Siegel and coauthors stated, adding that racial and geographic disparities persist in preventable cancers, including those of the lung and cervix.

“Increased investment in both the equitable application of existing cancer control interventions and basic and clinical research to further advance treatment options would undoubtedly accelerate progress against cancer,” said the investigators. The report appears in CA: A Cancer Journal for Clinicians.

While the decline in lung cancer death rates is good news, the disease remains a major killer, responsible for more deaths than breast, colorectal, and ovarian cancer combined, said Jacques P. Fontaine, MD, a thoracic surgeon at Moffitt Cancer Center in Tampa, Fla.

“Five-year survival rates are still around the 18%-20% range, which is much lower than breast and prostate cancer,” Dr. Fontaine said in an interview. “Nonetheless, we’ve made a little dent in that, and we’re improving.”

Two other factors that have helped spur that improvement, according to Dr. Fontaine, are the reduced incidence of squamous cell carcinomas, which are linked to smoking, and the increased use of lung cancer screening with low-dose computed tomography.

Squamous cell carcinomas tend to be a central rather than peripheral, which makes the tumors harder to resect: “Surgery is sometimes not an option, and even to this day in 2020, the single most effective treatment for lung cancer remains surgical resection,” said Dr. Fontaine.

Likewise, centrally located tumors may preclude giving high-dose radiation and may result in more “collateral damage” to healthy tissue, he added.

Landmark studies show that low-dose CT scans reduce lung cancer deaths by 20% or more; however, screening can have false-positive results that lead to unnecessary biopsies and other harms, suggesting that the procedures should be done in centers of excellence that provide high-quality, responsible screening for early lung cancer, Dr. Fontaine said.

While the drop in melanoma death rates is encouraging and, not surprising in light of new cutting-edge therapies, an ongoing unmet treatment need still exists, according to Vishal Anil Patel, MD, director of cutaneous oncology at the George Washington Cancer Center in Washington.

“We still have a lot to learn, and a way to go, because we’ve really just made the first breakthrough,” Dr. Patel said in an interview.

PHILADELPHIA – Testosterone gel for treatment of hypogonadism in older men boosted their left ventricular mass by 3.5% in a single year in the multicenter, double-blind, placebo-controlled Testosterone Cardiovascular Trial, although the clinical implications of this impressive increase remain unclear, Elizabeth Hutchins, MD, reported at the American Heart Association scientific sessions.

Bruce Jancin/MDedge News

“I do think these results should be considered as part of the safety profile for testosterone gel and also represent an interesting and understudied area for future research,” said Dr. Hutchins, a hospitalist affiliated with the Los Angeles Biomedical Research Center at Harbor-UCLA Medical Center.

The Testosterone Cardiovascular Trial was one of seven coordinated placebo-controlled, double-blind clinical trials of the impact of raising serum testosterone levels in older men with low testosterone. Some results of what are known as the TTrials have previously been reported (Endocr Rev. 2018 Jun 1;39[3]:369-86).

Dr. Hutchins presented new findings on the effect of treatment with 1% topical testosterone gel on body surface area–indexed left ventricular mass. The trial utilized a widely prescribed, commercially available product known as AndroGel. The study included 123 men over age 65 with low serum testosterone and coronary CT angiography images obtained at baseline and again after 1 year of double-blind testosterone gel or placebo. More than 80% of the men were above age 75, half were obese, more than two-thirds had hypertension, and 30% had diabetes.

The men initially applied 5 g of the testosterone gel daily, providing 15 mg/day of testosterone, with subsequent dosing adjustments as needed based on serum testosterone levels measured at a central laboratory. Participants were evaluated in office visits with serum testosterone measurements every 3 months. Testosterone levels in the men assigned to active treatment quickly rose to normal range and stayed there for the full 12 months, while the placebo-treated controls continued to have below-normal testosterone throughout the trial.

The key study finding was that LV mass indexed to body surface area rose significantly in the testosterone gel group, from an average of 71.5 g/m² at baseline to 74.8 g/m² at 1 year. That’s a statistically significant 3.5% increase. In contrast, LV mass remained flat across the year in controls: 73.8 g/m² at baseline and 73.3 g/m² at 12 months.

There was, however, no change over time in left or right atrial or ventricular chamber volumes in the testosterone gel recipients, nor in the controls.

Session comoderator Eric D. Peterson, MD, professor of medicine and a cardiologist at Duke University in Durham, N.C., said that “this is a very important topic,” then posed a provocative question to Dr. Hutchins: “If the intervention had been running instead of testosterone gel, would the results have looked similar, and would you be concluding that there should be a warning around the use of running?”

Dr. Hutchins replied that she’s given that question much thought.

“Of course, exercise leads to LV hypertrophy and we consider that to be good muscle, and high blood pressure leads to LV hypertrophy and we consider that bad muscle. So which one is it in this case? From what I can find in the literature, it seems that incremental increases in LV mass in the absence of being an athlete are deleterious. But I think we would need outcomes-based research to really answer that question,” she said.

Dr. Hutchins noted that this was the first-ever randomized controlled trial to measure the effect of testosterone therapy on LV mass in humans. The documented increase achieved with 1 year of testosterone gel doesn’t come close to reaching the threshold of LV hypertrophy, which is about 125 g/m² for men. But evidence from animal and observational human studies suggests that even in the absence of LV hypertrophy, increases in LV mass are associated with increased mortality, she added.

She reported having no financial conflicts regarding her study, sponsored by the National Institutes of Health.

But evidence from animal and observational human studies suggests that even in the absence of LV hypertrophy, increases in LV mass are associated with increased mortality, she added.

She reported having no financial conflicts regarding her study, sponsored by the National Institutes of Health.

PHILADELPHIA – Testosterone gel for treatment of hypogonadism in older men boosted their left ventricular mass by 3.5% in a single year in the multicenter, double-blind, placebo-controlled Testosterone Cardiovascular Trial, although the clinical implications of this impressive increase remain unclear, Elizabeth Hutchins, MD, reported at the American Heart Association scientific sessions.

“I do think these results should be considered as part of the safety profile for testosterone gel and also represent an interesting and understudied area for future research,” said Dr. Hutchins, a hospitalist affiliated with the Los Angeles Biomedical Research Center at Harbor-UCLA Medical Center.

The Testosterone Cardiovascular Trial was one of seven coordinated placebo-controlled, double-blind clinical trials of the impact of raising serum testosterone levels in older men with low testosterone. Some results of what are known as the TTrials have previously been reported (Endocr Rev. 2018 Jun 1;39[3]:369-86).

Dr. Hutchins presented new findings on the effect of treatment with 1% topical testosterone gel on body surface area–indexed left ventricular mass. The trial utilized a widely prescribed, commercially available product known as AndroGel. The study included 123 men over age 65 with low serum testosterone and coronary CT angiography images obtained at baseline and again after 1 year of double-blind testosterone gel or placebo. More than 80% of the men were above age 75, half were obese, more than two-thirds had hypertension, and 30% had diabetes.

The men initially applied 5 g of the testosterone gel daily, providing 15 mg/day of testosterone, with subsequent dosing adjustments as needed based on serum testosterone levels measured at a central laboratory. Participants were evaluated in office visits with serum testosterone measurements every 3 months. Testosterone levels in the men assigned to active treatment quickly rose to normal range and stayed there for the full 12 months, while the placebo-treated controls continued to have below-normal testosterone throughout the trial.

The key study finding was that LV mass indexed to body surface area rose significantly in the testosterone gel group, from an average of 71.5 g/m² at baseline to 74.8 g/m² at 1 year. That’s a statistically significant 3.5% increase. In contrast, LV mass remained flat across the year in controls: 73.8 g/m² at baseline and 73.3 g/m² at 12 months.

There was, however, no change over time in left or right atrial or ventricular chamber volumes in the testosterone gel recipients, nor in the controls.

Session comoderator Eric D. Peterson, MD, professor of medicine and a cardiologist at Duke University in Durham, N.C., said that “this is a very important topic,” then posed a provocative question to Dr. Hutchins: “If the intervention had been running instead of testosterone gel, would the results have looked similar, and would you be concluding that there should be a warning around the use of running?”

Dr. Hutchins replied that she’s given that question much thought.

“Of course, exercise leads to LV hypertrophy and we consider that to be good muscle, and high blood pressure leads to LV hypertrophy and we consider that bad muscle. So which one is it in this case? From what I can find in the literature, it seems that incremental increases in LV mass in the absence of being an athlete are deleterious. But I think we would need outcomes-based research to really answer that question,” she said.

Dr. Hutchins noted that this was the first-ever randomized controlled trial to measure the effect of testosterone therapy on LV mass in humans. The documented increase achieved with 1 year of testosterone gel doesn’t come close to reaching the threshold of LV hypertrophy, which is about 125 g/m² for men.

The Food and Drug Administration has issued a Safety Alert regarding the weight-management medication lorcaserin (Belviq, Belviq XR) after results from a clinical trial assessing the drug’s safety showed a possible increased risk of cancer.

“At this time, the cause of the cancer is uncertain, and we cannot conclude that lorcaserin contributes to the cancer risk. However, we wanted to make the public aware of this potential risk,” the agency said in a press release.

The agency advised that health care providers consider whether the benefits of taking lorcaserin outweighed the potential cancer risk, and that patients currently taking the medication should talk to their providers about the risks.

“We are continuing to evaluate the clinical trial results and will communicate our final conclusions and recommendations when we have completed our review,” the FDA noted in the statement.

Lorcaserin, a serotonin 2C receptor agonist, was approved by the FDA in 2012 at a dosage of 20 mg once daily for use with a reduced-calorie diet and increased physical activity as a means to improve weight loss in adults who are obese or overweight and have at least one weight-related medical problem, such as such as hypertension, type 2 diabetes, or dyslipidemia. In July 2016, the agency approved a New Drug Application for an extended-release, once-daily formulation.

Headache, dizziness, fatigue, nausea, dry mouth, and constipation are the more common adverse effects in patients without diabetes, whereas hypoglycemia, headache, back pain, cough, and fatigue are more common in patients with diabetes. The treatment is contraindicated for pregnancy.
