Abstract

Objective: The aim of the study was to determine the clinicopathological features that influence survival in patients with resected pancreatic ductal adenocarcinoma (PDA). Methods: The study used a single institution retrospective review of patients undergoing pancreaticoduodenectomy (PD) for PDA from 1993 to 2010. Results: Two hundred forty-six consecutive cases of resected PDA were identified: 128 males (52 %), median age 68 years. Median hospital length of stay was 8 days and 30-day mortality rate was 2.4 %. There were 101 (41.1 %) postoperative complications, 77 % of which were Dindo-Clavien Grade 3 or less. Overall survival was 85, 63, 25, and 15 % at 6 months, 1 year, 3 years, and 5 years, respectively, with a median survival of 17 months. Multivariate Cox proportional hazard modeling demonstrated lymph node ratio was negatively correlated with survival at all time points. Preoperative hypertension was a poor prognostic factor at 6 months, 3 years, and 5 years. The absence of postoperative complications was protective at 6 months whereas pancreatic leaks were associated with worse survival at 6 months. Abdominal pain on presentation, operative time, and estimated blood loss were also associated with decreased survival at various time points. Conclusion: The strongest prognostic variable for short- and long-term survival after PD for PDA is lymph node ratio. Short-term survival is influenced by the postoperative course.
