Geographic disparities in surgical treatment recommendation patterns and survival for pancreatic adenocarcinoma.
BACKGROUND: Previous studies have described pessimistic attitudes of physicians toward recommending surgery for early-stage pancreatic adenocarcinoma. However, the impact of geographic region on recommendation patterns of surgical treatment for potentially resectable pancreatic cancer is unknown.
METHODS: The SEER registry was used to identify patients with early-stage pancreatic adenocarcinoma (AJCC I-II) [2004-2013]. The exposure of interest was geographic region of diagnosis: Midwest, West, Southeast or Northeast. The endpoints of interest were recommendation of no surgery, and overall survival.
RESULTS: A total of 24,408 patients were identified [Midwest - 10.6%, West - 50.1%, Southeast - 21.7% and Northeast - 17.6%]. Overall, 38% of patients had a recommendation of no surgery by their provider. On univariate analysis, the likelihood of having a recommendation of no surgery was lowest in the NE [OR: Northeast (0.8), West (1.6), Southeast (1.3), and Midwest (Ref); p < 0.05 for all]. This association persisted following risk adjustment. Geographic region was an independent predictor of mortality, irrespective of resection status.
CONCLUSION: Significant disparities in surgical treatment recommendation patterns and survival for early-stage pancreatic cancer exist based on geographic location. Improved adherence to guideline-driven treatment recommendations, standardization of care processes, and regionalization may help stem the existing variability in care and outcomes.
