126 Background: Rising obesity rates have been documented in the United States population since the 1980s. Several studies have shown links between obesity and the incidence of – and the outcomes of – specific cancer types. Few studies have examined the prevalence of obesity among cancer patients at the time of diagnosis or among those who participate in clinical trials. We examined the prevalence of obesity over a 35-year period among patients enrolled in clinical treatment trials conducted by the SWOG Cancer Research Network. Methods: We analyzed body mass index (BMI) at registration among patients enrolled in phase II or III clinical trials conducted by SWOG. Adult patients (age≥18) participating in trials in obesity-related cancers between 1985 and 2020 were included. Obesity was classified as BMI ≥ 30 kg/m2. Multivariable logistic regression was used to examine time trends, adjusting for age, sex, race, and treatment type. Time was defined as year of enrollment and examined in separate models as continuous years and as 5-year intervals. We examined trends among patient subgroups by sex and by treatment type (chemotherapy, immunotherapy, and targeted therapy). Results: 16,374 patients enrolled in SWOG clinical trials conducted between 1985 and 2020 were analyzed. Patients were most commonly enrolled in trials for breast cancer (n = 6,327, 38.6%), colon cancer (n = 2,408, 14.7%), multiple myeloma (n = 2,112, 12.9%), and rectal cancer (n = 1,785, 10.9%). Overall, 32% of patients were obese (n = 5,252). Unadjusted obesity rates among trial participants increased from 18% in 1985-1990 to 42% in 2016-2020, compared to an increase from 23% to 42% among US adults over a similar period. Obesity prevalence rates increased over time for all sex, age, and race subgroups. Overall, there was an increasing linear trend in obesity (OR = 1.36 for each 5-year increase, 95% CI: 1.33-1.39, p < .0001). These trends persisted with adjustments for age, sex, race, and treatment type (OR = 1.35 per 5-year increase, 95% CI: 1.31-1.39, p < .0001). Positive linear trends in obesity prevalence were observed for all subgroups by sex and treatment type. There was no evidence of difference in trends between males and females or between the three treatment types. Conclusions: We observed an increasing trend in obesity among patients participating in clinical trials for obesity-related cancers, mirroring US adult obesity rates. Our findings indicate good representation of obese patients in clinical treatment trials, which has favorable implications for the applicability of trial findings to this group of patients.

AbstractThis study provides trends in obesity prevalence in adults from 2013 to 2016 in France. 63,582 men and women from independent samples upon inclusion from the Constances cohort were included. Anthropometrics were measured at Health Screening Centers and obesity defined as a Body mass index (BMI) ≥ 30 kg/m2; obesity classes according to BMI are as follows: class 1 [30–34.9]; class 2 [35–39.9]; class 3 [≥ 40 kg/m2]. Linear trends across obesity classes by sex and age groups were examined in regression models and percentage point change from 2013 to 2016 for each age category calculated. All analyses accounted for sample weights for non-response, age and sex-calibrated to the French population. Prevalence of obesity ranged from 14.2 to 15.2% and from 14 to 15.3% in women and men respectively from 2013 to 2016. Class 1 obesity category prevalence was the only one to increase significantly across survey years in both men and women (p for linear trend = 0.04 and 0.01 in women and men respectively). The only significant increase for obesity was observed in the age group 18–29 y in both women and men (+ 2.71% and + 3.26% point increase respectively, equivalent to an approximate rise of 50% in women and 93% in men, p = 0.03 and 0.02 respectively). After adjustment for survey non-response and for age and sex distribution, the results show that class 1 obesity prevalence has significantly increased in both women and men from 2013 to 2016, and only in young adults in a representative sample of the French population aged 18–69 years old.

Abstract BACKGROUND Patients in rural communities have less access to optimal cancer care and clinical trials. For GBM, access to experimental therapies, and consideration of a clinical trial is embedded in national guidelines. Still, the availability of clinical trials to rural communities, representing 20% of the US population, has not been described. METHODS We queried ClinicalTrials.gov for glioblastoma interventional treatment trials opened between 1/2010 and 1/2020 in the United States. We created a Structured Query Language database and leveraged Google application programming interfaces (API) Places to find name and street addresses for the sites, and Google’s Geocode API to determine the county location. Counties were classified by US Department of Agriculture Rural-Urban Continuum Codes (RUCC 1–3 = urban and RUCC 4–9 = rural). We used z-ratios for rural-urban statistical comparisons. RESULTS We identified 406 interventional treatment trials for GBM at 1491 unique sites. 8.7% of unique sites were in rural settings. Rural sites opened an average of 1.7 trials/site and urban sites 2.8 trials/site from 1/2010–1/2020. Rural sites offered more phase II trials (63% vs 57%, p= 0.03) and fewer phase I trials (22% vs 28%, p= 0.01) than urban sites. Rural locations were more likely to offer federally-sponsored trials (p&lt; 0.002). There were no investigator-initiated or single-institution trials offered at rural locations, and only 1% of industry trials were offered rurally. DISCUSSION Clinical trials for GBM were rarely open in rural areas, and were more dependent on federal funding. Clinical trials are likely difficult to access for rural patients, and this has important implications for the generalizability of research as well as how we engage the field of neuro-oncology and patient advocacy groups in improving patient access to trials. Increasing the number of clinical trials in rural locations may enable more rural patients to access and enroll in GBM studies.

Purpose A prior analysis by the Southwest Oncology Group (SWOG) showed that women and African American patients were adequately represented on cancer clinical treatment trials but that older patients were substantially underrepresented. Twenty-five percent of patients ≥ 65 years old were enrolled onto SWOG trials from 1993 to 1996, whereas 63% of all patients with cancer were ≥ 65 years old. Recognition of this under-representation led to a change in Medicare policy in 2000 to include coverage of routine patient care costs of clinical trials. We conducted an updated analysis of accrual trends. Methods The proportions of enrollment onto SWOG treatment trials by sex, race/ethnicity, and age (≥ 65 years) were computed for the years 1997 to 2000; corresponding rates in the United States were derived from US Census and National Cancer Institute Surveillance, Epidemiology, and End Results data. Additionally, method of payment data were analyzed over time (1993 to 2003) to assess whether patterns in method of payment changed with the new Year 2000 Medicare policy on clinical trials coverage. Results The results showed continued adequate representation by sex and race/ethnicity. Older patient accrual on SWOG trials increased significantly since 2000, with 31% of patients ≥ 65 years old enrolled from 1997 to 2000 and 38% enrolled from 2001 to 2003 (v 25% from 1993 to 1996). The percentage of patients using Medicare plus supplemental insurance also increased beginning in 2000, whereas the percentage of patients using Medicare alone remained the same. Conclusion Method of payment analyses provided evidence that the Year 2000 Medicare policy change had a positive impact, but only for those patients with supplemental private coverage of coinsurance costs. Improvements in the Medicare payment structure could further increase older patient participation in clinical trials.

10514 Background: Colorectal cancer (CRC) affects approximately 104,000 patients (pts) annually in the United States, up to 45% of which are estimated to be genetic and/or familial. Aligned with clinical guidelines, in 2020, a large U.S. insurer established Medical Policy allowing for and reimbursing germline genetic testing (GGT) for all CRC pts. This study reports overall uptake of GGT in CRC pts under this inclusive policy, actionable findings and treatment implications for pts tested, stratified by self-reported ancestry/ethnicity. Methods: Two independent de-identified datasets were reviewed, including administrative claims data of commercially insured and Medicare Advantage enrollees, aged 18+ with CRC (≥1 claim with ICD10 C18, C19 or C20 in the first position) who were continuously enrolled (CE) in the health plan from 1/2019-10/2020. Evidence of genetic testing based on CPT codes, was examined during 2020. A second de-identified dataset of CRC pts whose GGT was billed to the insurer under the Medical Policy, was also reviewed. Patient demographics, clinical information and GGT results were descriptively analyzed. Results: Of the >18,000,000 CE enrollees, 55,595 were identified as CRC pts, of whom 1,675 (3%) received GGT. From the GGT dataset, 788 pts had test results available for review. 143 (18%) pts had pathogenic/likely pathogenic (P/LP) variants in genes including MSH2, MLH1, PMS2, MSH6, CHEK2, APC, BRCA2, ATM, MUTYH (biallelic). Of pts with P/LP variants, 96 (67%) were potentially eligible for precision therapy and/or clinical treatment trials. Overall, 133 (93%) had P/LP variants in genes with precision therapy, clinical trial and/or published management implications. In a subset of pts (n=674) with ethnicity data; Asian, Black/African-American and Hispanic pts showed lower relative uptake of germline testing than Caucasians (Table). Conclusions: Despite Medical Policy allowing for GGT for all pts with CRC, only 3% of eligible pts received testing. If all CRC pts had been tested, these data suggest up to 6,705 pts with P/LP variants conferring potential eligibility for precision therapy (PD-1/PD-L1 inhibitors) or clinical treatment trials (PARP inhibitors), and an additional 2,602 pts with mutations in genes with published management recommendations, could have been identified, but were missed. Additional research is needed to identify obstacles to systematic implementation of this Medical Policy, the best timing of GGT to prevent CRC and improve access to underrepresented populations.

Background: The growing epidemic of obesity in the United States (US) is associated with cardiovascular (CV) morbidity and mortality. We evaluated the impact of the increasing obesity prevalence on the CV health of young American adults. Methods: The age-adjusted weighted prevalence of hypertension, diabetes, and hypercholesterolemia was estimated from the 2008-2018 National Health and Nutrition Examination Survey (NHANES) in American adults aged 18-44 years, stratified by the presence of obesity. The trends were evaluated using a piecewise linear regression approach. The odds for CV risk factors were estimated using multivariable-adjusted logistic regression models. Results: Among 14,919 young adults, the prevalence of obesity was 33.9% (95% CI: 32.6-35.3%). Obese young adults were more likely to be non-Hispanic Blacks and in lower socioeconomic and educational attainment strata (p<0.05 for all). Obese young adults had a greater risk of having hypertension (adjusted odds ratio [aOR]: 3.0 [95% CI: 2.7-3.4]), diabetes (aOR: 4.3 [95% CI: 3.3-5.6]), and hyperlipidemia (aOR: 1.47 [95% CI: 1.3-1.7]). Among obese, hypertension increased from 36.5% (33.9-39.1%) in 2007-2010 to 39.4% (35.6-43.1%) in 2015-2018 (p= 0.07) and diabetes increased from 4.7% (3.6-5.8%) in 2007-2010 to 7.1% (5.3-9.0%) in 2015-2018 (p=0.11). A modest increase in diabetes was seen in non-obese individuals ( Table ). Hypercholesterolemia prevalence remained unchanged from 12.6% (95% CI: 10.6-14.7%) 2007-2010 to 10.9% (95% CI: 9.0-12.8%) in 2015-2018 (p=0.27) among obese young adults. Non-obese young adults showed a decline in hypercholesterolemia from 9.5% (95% CI: 8.0-11.0%) in 2007- 2010 to 7.1% (95% CI: 5.8-8.4%) in 2015-2018 (p=0.002). Conclusions: Nearly one-in-every three young American adults have obesity, which is accompanied by a two-fold higher prevalence of CV risk factors. The CV morbidity in young adults is expected to increase with an increasing prevalence of obesity..

Background: Obesity has become a national epidemic, and is associated with increased risk for comorbid diseases including end-stage renal disease (ESRD). Among ESRD patients, obesity may improve dialysis-survival but decreases likelihood of transplantation, and as such, obesity prevalence may directly impact growth of the incident dialysis population. Methods: Incident adult ESRD patients with complete body mass index (BMI, kg/m 2 ) data were identified from the United States Renal Data System from 01/01/1995-12/31/2010 (n=1,822,598). Data from the Behavioral Risk Factor Surveillance System of the Centers for Disease Control and Prevention (n=4,303,471) represented the US population when weighted. Trends in BMI and obesity classes I (BMI of 30-34.9), II (BMI of 35-39.9), and III (BMI ≥40) were examined by year of dialysis initiation. Trends in median BMI slope were compared between the ESRD and US populations using linear regression. Results: Median BMI of ESRD patients in 1995 was 24.2 as compared to 28.0 in 2010, a 15.7% increase, while the US population’s median BMI increased from 24.2 in 1995 to 25.6 in 2010, a 5.8% increase. Comparable trends were noted with respect to prevalence of obesity classes I, II, and III (Table). BMI increase among the ESRD population was significantly more rapid than among the US population (β: 0.15, 95% CI: 0.14-0.17, p<0.001) (Figure). Conclusion: The median BMI of ESRD patients and prevalence of obesity among ESRD patients is increasing more rapidly than the US population. Given the increased dialysis-survival and decreased likelihood of transplantation associated with obesity, healthcare costs will likely increase, and thus, future research should be directed at examining medical expenditures.

Trends in clinical trials for pancreatic cancer between 2011-2020 were tracked in the Pancreatic Cancer Action Network database originally designed to assist in identifying open trials for eligible patients. More than 125 trials specific for pancreatic cancer or including no more than one additional cancer type have been open each year, the majority for patients with a diagnosis of pancreatic adenocarcinoma (PAC). The trends indicate an active and progressive pancreatic cancer research community and include an increasing number of trials for previously treated patients, the emergence of trials for post-adjuvant or maintenance therapy, an increasing number of research-intensive phase 0 trials, increasing seamless phase I/II and II/III trials to improve efficiency, and an increasing number of phase III trials despite historical failures. Trials were analyzed by treatment type and included trials to optimize standard chemotherapy or radiation therapy, trials targeting tumor pathways, the stroma, or the immune system, biomarker-specified trials, and a miscellaneous category of trials testing tumor metabolism, complementary medicine approaches, or alternate energy sources. There was a dramatic increase in immunotherapy trials over this time. Several biomarker-specified trials were initiated, and FDA approval was obtained for biomarker-specified targeted agents, many in a tissue-agnostic setting, indicating an increase in a precision medicine approach to pancreatic cancer treatment. An increasing number of trials tested non-standard approaches, many which progressed to phase III. The trends suggest an encouraging trajectory of pancreatic cancer clinical research.

The prevalence of obesity has been persistent amongst Hispanics over the last 20 years. Socioeconomic inequities have led to delayed diagnosis and treatment of chronic medical conditions related to obesity. Factors contributing include lack of insurance and insufficient health education. It is well-documented that obesity amongst Hispanics is higher in comparison to non-Hispanics, but it is not well-understood how the socioeconomic context along with Hispanic ethnic concentration impact the prevalence of obesity within a community. Specifically studying obesity within Hispanic dominant regions of the United States, along the Texas–Mexico border will aid in understanding this relationship. El Paso, Texas is predominantly Mexican-origin Hispanic, making up 83% of the county’s total population. Through the use of electronic medical records, BMI averages along with obesity prevalence were analyzed for 161 census tracts in the El Paso County. Geographic weighted regression and Hot Spot technology were used to analyze the data. This study did identify a positive association between Hispanic ethnic concentration and obesity prevalence within the El Paso County. Median income did have a direct effect on obesity prevalence while evidence demonstrates that higher education is protective for health.

Adult obesity is a growing problem. From 1962 to 2006, obesity prevalence nearly tripled to 35.1 percent of adults. The rising prevalence of obesity is not limited to a particular socioeconomic group and is not unique to the United States. Should this widespread obesity epidemic be a cause for alarm? From a personal health perspective, the answer is an emphatic “yes.” But when it comes to justifications of public policy for reducing obesity, the analysis becomes more complex. A common starting point is the assertion that those who are obese impose higher health costs on the rest of the population—a statement which is then taken to justify public policy interventions. But the question of who pays for obesity is an empirical one, and it involves analysis of how obese people fare in labor markets and health insurance markets. We will argue that the existing literature on these topics suggests that obese people on average do bear the costs and benefits of their eating and exercise habits. We begin by estimating the lifetime costs of obesity. We then discuss the extent to which private health insurance pools together obese and thin, whether health insurance causes obesity, and whether being fat might actually cause positive externalities for those who are not obese. If public policy to reduce obesity is not justified on the grounds of external costs imposed on others, then the remaining potential justification would need to be on the basis of helping people to address problems of ignorance or self-control that lead to obesity. In the conclusion, we offer a few thoughts about some complexities of such a justification.

AbstractEighty-seven percent of cervix cancer occurs in less-developed regions of the world, and there is up to an 18-fold difference in mortality rate for cervix cancer depending on the region of the world. The Cervix Cancer Research Network (CCRN) was founded through the Gynecologic Cancer InterGroup with the aim of improving access to clinical trials in cervix cancer worldwide, and in so doing improving standards of care. The CCRN recently held its first international educational symposium in Bangkok. Sixty-two participants attended from 16 different countries including Pakistan, India, Bangladesh, Thailand, Malaysia, Singapore, Philippines, Taiwan, China, Vietnam, Korea, Japan, Columbia, Brazil, Canada, and the United States. The focus of this symposium was to evaluate progress, to promote new clinical trials for the CCRN, and to provide education regarding the role of brachytherapy in the treatment of cervical cancer.
