AIM:To establish the prognosis and feasibility of en-bloc vascular resection of stage pancreatic adenocarcinoma of the head and uncinate process.METHODS:We retrospectively analyzed 87 patients with stage pancreatic adenocarcinoma,who were subjected to pancreaticoduodenectomy (PD) and pylo-rus-preserving PD (PPPD) between 1996 and 2006 in Chang Gung Memorial Hospital,Taiwan. Twelve and 75 patients underwent PD/PPPD with and without resection of portal vein/superior mesenteric vein (PV/SMV),respectively.RESULTS:The overall 1-and 3-year survival rates of patients undergoing PD/PPPD with and without vas-cular resection were 50.0% and 16.7%,and 44.4% and 12.2%,respectively. Morbidity and mortality rates in the PV/SMV resection vs non-resection group were 50.0% and 0.0%,and 40.0% and 2.7%,respectively. In multivariate analysis,serum bilirubin,histological differentiation and adjuvant chemotherapy were independent prognostic factors that influenced survival.CONCLUSION:In stage adenocarcinoma of the pancreatic head and uncinate process,serum bilirubin,histological differentiation and adjuvant chemotherapy were independent prognostic factors,and en-bloc vascular resection is a feasible option in carefully selected patients.
