Many groups advocate performing these resections at high-volume hospitals (HVHs), given their complexity. We therefore sought to explore whether RPS surgery has indeed begun to regionalize to HVHs in the same manner as pancreatic cancer (PC) surgery during the last decade.Abstract: METHODS:: We identified 70,763 patients who underwent surgical resection for RPS or PC using the National Cancer Database (2004 to 2015). Patients were stratified by hospital surgical volume. We performed an adjusted time trend analysis to compare trends in performance of surgery at HVHs for RPS versus PC. Multivariable logistic analyses were then performed, controlling for covariables, to elucidate relationships between patient-, hospital-, and treatment-related variables that may contribute to these observed trends.Abstract: RESULTS:: Only 9.6% of patients underwent RPS surgery at HVHs. During this time period, the odds ratio of undergoing RPS compared with pancreatectomy at HVHs was 0.65 ( P < .05). Time trend analysis estimated that whereas both procedures are regionalizing, the rate of RPS regionalization grew at 30.5% of the rate of PC (1.017 v 1.056; P < .001) and remained consistent after using several hospital volume thresholds and hospital volume as a continuous variable.Abstract: CONCLUSION:: Results from this retrospective multi-institutional analysis uncovered a lag in the regionalization of surgery for RPS compared with PC surgery. These findings reinforce the call to regionalize surgery for RPS to HVHs in a manner that is similar to that of other procedures in complex cancer surgery.
