Survival after pancreatic cancer surgery is extremely unfavorable even after curative resection. Prognostic factors have been explored but remain largely undefined. The present study was to identify the role of clinical and laboratory variables in the prognostic significance of resectable pancreatic adenocarcinoma. A total of 96 patients who underwent curative resection for pancreatic cancer were included. Survival was evaluated based on complete follow-up visits and was associated with potential prognostic factors using the Kaplan-Meier method and Cox proportional hazard model survival analyses. The results showed that prognostic variables significantly reduced survival, including old age, poorly differentiated tumors, elevated tumor markers and positive lymph node metastasis (LNM). Age of older than 60 years (HR=1.83, P=0.04), LNM (HR=2.22, P=0.01), lymph node ratio (0<LNR≤0.2, HR=1.38, P=0.042; LNR>0.2, HR=1.92, P=0.017), initial CA199 (HR=4.80, P=0.004), and CEA level (HR=2.59, P=0.019) were identified as independent prognostic factors by multivariate analysis. It was concluded that LNR may be potent predictor of survival and suggests that surgeons and the pathologists should thoroughly assess lymph nodes prior to surgery.
