Predictors of long-term survival after pancreaticoduodenectomy for peri-ampullary adenocarcinoma: A retrospective study of 5-year survivors

Pancreaticoduodenectomy (PD) is the standard curative treatment for periampullary tumors. The aim of this study is to report the incidence and predictors of long-term survival (≥ 5 years) after PD. This study included patients who underwent PD for pathologically proven periampullary adenocarcinomas. Patients were divided into 2 groups: group (I) patients who survived less than 5 years and group (II) patients who survived ≥ 5 years. There were 47 (20.6%) long-term survivors (≥ 5 years) among 228 patients underwent PD for periampullary adenocarcinoma. Patients with ampullary adenocarcinoma represented 31 (66.0%) of the long-term survivors. Primary analysis showed that favourable factors for long-term survival include age
