Analysis of pancreatic adenocarcinoma tumor staging and resection according to previous body mass index and diabetes duration.

Background/aims: Obesity and diabetes mellitus (DM) are associated with pancreatic cancer. The present study evaluated tumor staging and resection of pancreatic adenocarcinoma (PaC) according to previous Body Mass Index (BMI), BMI on admission and DM duration.

Methods: A retrospective analysis of 151 consecutive patients with PaC was performed: 73 were evaluated according to BMI preceding tumor-related weight loss and BMI on admission; 118 according to DM diagnosis; and 38 were assessed according to DM duration (less than 1 year [recent-onset] versus more than 2 years [long-standing]).
