Abstract
BACKGROUND: Racial/ethnic disparities in cancer outcomes may relate to variations in receipt of National Comprehensive Cancer Network (NCCN) guideline compliant care. PATIENTS AND METHODS: Patients undergoing resection of cholangiocarcinoma (CCA) between 2004 and 2015 were identified using the National Cancer Database (NCDB). Institutions treating Black and Hispanic patients within the top decile were categorized as minority-serving hospitals (MSH). Factors associated with receipt of NCCN-compliant care, and the impact of NCCN compliance on overall survival (OS), were evaluated. RESULTS: Among 16,108 patients who underwent resection of CCA, the majority of patients were treated at non-MSH (n = 14,779, 91.8%), while a smaller subset underwent resection of CCA at MSH (n = 1329, 8.2%). Patients treated at MSH facilities tended to be younger (MSH: 65 years versus non-MSH: 67 years), Black or Hispanic (MSH: 59.9% versus non-MSH: 13.4%), and uninsured (MSH: 11.6% versus non-MSH: 2.2%). While overall compliance with NCCN care was 73.0% (n = 11,762), guideline-compliant care was less common at MSH (MSH: 68.8% versus non-MSH: 73.4%; p < 0.001). On multivariable analyses, the odds of receiving non-NCCN compliant care remained lower at MSH (OR 0.76, 95% CI 0.65-0.88). While white patients had similar odds of NCCN-compliant care with minority patients when treated at MSH (OR 0.98, 95% CI 0.75-1.28), minority patients had lower odds of receiving guideline-compliant care when treated at non-MSH (OR 0.85, 95% CI 0.75-0.96). Failure to comply with NCCN guidelines was associated with worse long-term outcomes (HR 1.60, 95% CI 1.52-1.69). CONCLUSIONS: Patients treated at MSH had decreased odds to receive NCCN-compliant care following resection of CCA. Failure to comply with guideline-based cancer care was associated with worse long-term outcomes.
