Increasing regionalization for esophagectomy for cancer may lead patients to travel for surgery at one institution and receive chemotherapy at another closer to home. We explore the effects on survival for care fragmentation, the Commission on Cancer status of secondary institutions providing chemotherapy, and the type of institution performing surgery.
We queried the National Cancer Database to identify all patients who underwent esophagectomy for esophageal cancer and received perioperative chemotherapy between 2006 and 2019. Patients were divided into single-center care, fragmented-to-Commission on Cancer care, or fragmented-to-non-Commission on Cancer care. We identified associations using multivariable logistic regression, Kaplan-Meier survival analyses, and Cox proportional hazards models.
A total of 18,502 patients met the criteria for inclusion: 8,290 (44.8%) received single-center care; 3,414 (18.5%) fragmented-to-Commission on Cancer care; and 6,798 (36.4%) fragmented-to-non-Commission on Cancer care. Fragmented care was more likely in White patients (adjusted odds ratio = 1.25; P < .001) and in patients nonadjacent to a metropolitan area (adjusted odds ratio = 1.36; P < .001). Overall survival was equivalent between single-center and fragmented care, but undergoing an esophagectomy at an academic center was associated with improved survival (adjusted hazard ratio = 0.82; P = .016). In patients with an esophagectomy at a nonacademic center, overall survival was best if perioperative chemotherapy was administered at Commission on Cancer-accredited facilities compared with chemotherapy at fragmented-to-non-Commission on Cancer centers (P = .022).
Most of the esophageal cancer care in the US is fragmented at multiple institutions. When care is fragmented, it is most commonly at non-Commission on Cancer centers for perioperative chemotherapy. Overall survival is best when esophagectomy is performed at an academic center, and perioperative therapy is administered at Commission on Cancer-accredited facilities.
