Fragmented care in localized pancreatic cancer: Is commission on cancer accreditation associated with improved overall survival?

Background: Prior studies of fragmentation of care in pancreatic cancer have not adjusted for indicators of hospital quality such as Commission on Cancer accreditation. The effect of fragmentation of care has not been well defined. Methods: We queried the National Cancer Database to identify patients undergoing pancreaticoduodenectomy and distal pancreatectomy with perioperative systemic therapy for clinical stages I -III pancreatic cancer between 2006 and 2019. Patients who received systemic therapy at a center different than the center performing surgery were categorized as having fragmentation of care. Patients having fragmentation of care were further categorized on the basis of whether (fragmentation of care Commission on Cancer) or not (fragmentation of care non -Commission on Cancer) systemic therapy was administered at a facility accredited by the Commission on Cancer. Results: A total of 11,732 patients met inclusion criteria; 5,668 (48.3%) underwent fragmentation of care, and 3,426 (29.2%) fragmentation of care non -Commission on Cancer. Patients undergoing fragmentation of care non -Commission on Cancer were less likely to receive neoadjuvant systemic therapy than those undergoing fragmentation of care Commission on Cancer or non -fragmented care (27.7% vs 40.1% vs 36.8%, P < .001). On Cox analysis, advanced age, comorbid disease, node -positive disease, and facility type were associated with risk of overall survival. Fragmentation of care was not (adjusted hazard ratio = 0.99, 95% confidence interval [0.94-1.06], P = .8). On Kaplan -Meier analysis, there were no significant differences in 5 -year overall survival between treatment cohorts. Conclusion: In patients undergoing fragmentation of care for localized pancreatic cancer, those treated with systemic therapy in Commission on Cancer accredited facilities are more likely to be given neoadjuvant therapy but demonstrate no significant improvement in survival relative to those undergoing non -fragmented care or those undergoing fragmentation of care but receiving systemic therapy in nonaccredited facilities.
