Core Tip

Core tip: It remains controversial whether body mass index (BMI) influences the prognosis of pancreatic cancer. The strengths of this study included a large quantity of patients and the accurate BMI categorization according the Asian criterion. To the best of our knowledge, it is the largest study in Asia to evaluate the prognostic role of BMI on the overall survival of pancreatic cancer patients. Our results showed no significant influence of BMI on the overall survival of pancreatic ductal adenocarcinoma patients and are consistent with those of many other studies.
