Background: Racial/ethnic disparities in pancreatic adenocarcinoma (PDAC) outcomes may relate to receipt of National Comprehensive Cancer Network (NCCN) guideline-compliant care. We assessed the association between treatment at minority-serving hospitals (MSH) and receipt of NCCN-compliant care.
Patients and methods: Patients who underwent resection of early-stage PDAC between 2006 and 2019 were identified from the National Cancer Database (NCDB). MSH was defined as the top decile of facilities treating minority ethnicities (Black and/or Hispanic). Factors associated with receipt of NCCN-compliant care and its impact on overall survival (OS) were assessed.
Results: Among 44,873 patients who underwent resection of PDAC, most were treated at non-MSH (n = 42,571, 94.9%), while a smaller subset were treated at MSH (n = 2302, 5.1%). Patients treated at MSH were more likely to be at a younger median age (MSH 66 years versus non-MSH 67 years), Black or Hispanic (MSH 58.4% versus non-MSH 12.0%), and not insured (MSH 7.8% versus non-MSH 1.6%). While 71.7% (n = 31,182) of patients were compliant with NCCN care, guideline-compliant care was lower at MSH (MSH 62.5% versus non-MSH 72.2%). On multivariable analysis, receiving care at MSH was associated with not receiving guideline-compliant care [odds ratio (OR) 0.63, 95% confidence interval (CI) 0.53-0.74]. At non-MSH, non-white patients had lower odds of receiving guideline-compliant PDCA care (OR 0.85, 95% CI 0.78-0.91). Failure to comply was associated with worse overall survival (OS) [hazard ratio (HR) 1.50, 95% CI 1.46-1.54, all p < 0.001].
Conclusions: Patients with PDAC treated at MSH and minorities treated at non-MSH were less likely to receive NCCN-compliant care. Failure to comply with guideline-based PDAC treatment was associated with worse OS.
