BACKGROUND: To reduce technical variation in cancer surgery, the Commission on Cancer (CoC) recently implemented 6 operative standards as part of its national cancer center accreditation process. CoC sites are evaluated for compliance with these standards through scheduled visits conducted by trained site reviewers. We characterized site reviewers’ perspectives on the implementation of the operative standards. STUDY DESIGN: Twenty interviews were conducted with CoC site reviewers using a semistructured interview guide based on the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework. Themes were identified using thematic analysis mapped to the updated Consolidated Framework for Implementation Research. RESULTS: Site reviewers viewed the operative standards as an effective starting point for improving technical quality and were optimistic the standards would lead to positive change. Compliance was associated with supportive site leadership, effective interdisciplinary communication, and the availability of adequate personnel and institutional resources. In contrast, resistance from surgeons was identified as a key barrier. CoC site reviewers interpret their role as extending beyond assessing compliance, viewing themselves as advocates, educators, and partners to the sites. CONCLUSIONS: Overall, CoC site reviewers perceive the operative standards favorably. To enhance implementation of the operative standards, efforts should focus on modifiable institutional and individual-level factors, such as leadership support and surgeon engagement. Additionally, the multifaceted role of the site reviewers presents a valuable opportunity to improve compliance by formalizing the supportive relationship between reviewers and sites.

Background: Prospective, randomized trials are needed to determine optimal treatment approaches for palliative care problems such as malignant bowel obstruction (MBO). Randomization poses unique issues for such studies, especially with divergent treatment approaches and varying levels of equipoise. We report our experience accruing randomized patients to the Prospective Comparative Effectiveness Trial for Malignant Bowel Obstruction (SWOG S1316) study, comparing surgical and nonsurgical management of MBO. Methods: Patients with MBO who were surgical candidates and had treatment equipoise were accrued and offered randomization to surgical or nonsurgical management. Patients choosing nonrandomization were offered prospective observation. Trial details are listed on www.clinicaltrials.gov (NCT #02270450). An accrual algorithm was developed to enhance enrollment. Results: Accrual is ongoing with 176 patients enrolled. Most (89%) patients chose nonrandomization, opting for nonsurgical management. Of 25 sites that have accrued to this study, 6 enrolled patients on the randomization arm. Approximately 59% (20/34) of the randomization accrual goal has been achieved. Patient-related factors and clinician bias have been the most prevalent reasons for lack of randomization. An algorithm was developed from clinician experience to aid randomization. Using principles in this tool, repeated physician conversations discussing treatment options and goals of care, and a supportive team–approach has helped increase accrual. Conclusions: Experience gained from the S1316 study can aid future palliative care trials. Although difficult, it is possible to randomize patients to palliative studies by giving clinicians clear recommendations utilizing an algorithm of conversation, allotment of necessary time to discuss the trial, and encouragement to overcome internal bias.

BACKGROUND Individuals from disadvantaged communities are among the millions of uninsured Americans gaining insurance under the Affordable Care Act. The extent to which health insurance can mitigate the effects of the social determinants of health on cancer care is unknown. METHODS This study linked the Surveillance, Epidemiology, and End Results registries to US Census data to study patients diagnosed with the 4 leading causes of cancer deaths between 2007 and 2011. A county‐level social determinant score was developed with 5 measures of wealth, education, and employment. Patients were stratified into quintiles, with the lowest quintile representing the most disadvantaged communities. Logistic regression and Cox proportional hazards models were used to estimate associations and cancer‐specific survival. RESULTS A total of 364,507 patients aged 18 to 64 years were identified (134,105 with breast cancer, 106,914 with prostate cancer, 62,606 with lung cancer, and 60,882 with colorectal cancer). Overall, patients from the most disadvantaged communities (median household income, $42,885; patients below the poverty level, 22%; patients completing college, 17%) were more likely to present with distant disease (odds ratio, 1.6; P < .001) and were less likely to receive cancer‐directed surgery (odds ratio, 0.8; P < .001) than the least disadvantaged communities (median income, $78,249; patients below the poverty level, 9%; patients completing college, 42%). The differences persisted across quintiles regardless of the insurance status. The effect of having insurance on cancer‐specific survival was more pronounced in disadvantaged communities (relative benefit at 3 years, 40% vs 31%). However, it did not fully mitigate the effect of social determinants on mortality (hazard ratio, 0.75 vs 0.68; P < .001). CONCLUSIONS Cancer patients from disadvantaged communities benefit most from health insurance, and there is a reduction in disparities in outcome. However, the gap produced by social determinants of health cannot be bridged by insurance alone. Cancer 2017;123:1219–1227. © 2016 American Cancer Society .

BACKGROUNDAlthough colorectal cancer (CRC) screening guidelines recommend initiating screening at age 50 years, the percentage of cancer cases in younger patients is increasing. To the authors' knowledge, the national treatment patterns and outcomes of these patients are largely unknown.METHODSThe current study was a population‐based, retrospective cohort study of the nationally representative Surveillance, Epidemiology, and End Results registry for patients diagnosed with CRC from 1998 through 2011. Patients were categorized as being younger or older than the recommended screening age. Differences with regard to stage of disease at diagnosis, patterns of therapy, and disease‐specific survival were compared between age groups using multinomial regression, multiple regression, Cox proportional hazards regression, and Weibull survival analysis.RESULTSOf 258,024 patients with CRC, 37,847 (15%) were aged <50 years. Young patients were more likely to present with regional (relative risk ratio, 1.3; P<.001) or distant (relative risk ratio, 1.5; P<.001) disease. Patients with CRC with distant metastasis in the younger age group were more likely to receive surgical therapy for their primary tumor (adjusted probability: 72% vs 63%; P<.001), and radiotherapy also was more likely in younger patients with CRC (adjusted probability: 53% vs 48%; P<.001). Patients younger than the recommended screening age had better overall disease‐specific survival (hazards ratio, 0.77; P<.001), despite a larger percentage of these individuals presenting with advanced disease.CONCLUSIONSPatients with CRC diagnosed at age <50 years are more likely to present with advanced‐stage disease. However, they receive more aggressive therapy and achieve longer disease‐specific survival, despite the greater percentage of patients with advanced‐stage disease. These findings suggest the need for improved risk assessment and screening decisions for younger adults. Cancer 2016;122:929–34. © 2016 American Cancer Society.
