Abstract

Background: Esophageal adenocarcinoma is often associated with obesity, and a 5 Kg m-2 increase in body mass index (BMI) has, in fact, been found to be strongly associated with the risk of this type of cancer (RR, 1.52; p <0.0001). Esophagectomy with lymphoadenectomy is the mainstay of therapy for these patients. The aim of this study was to assess and compare the surgical and oncological outcomes as well as the survival rates of underweight, normal weight, overweight, and obese patients following esophagectomy for esophageal cancer. Patients and Methods: Data relative to 1,127 patients with esophageal adenocarcinoma presenting at a specialized tertiary hospital (the Center of Esophageal Diseases for the Veneto Region) between 2000 and 2008 were prospectively collected. The 278 subjects whose BMI values before disease onset were available and underwent esophagectomy were enrolled in the study. Sixty-one of the 278 patients were classified as obese (BMI >30), 121 were classified as overweight (BMI, 25-29.9), 81 were classified as normal weight (BMI
