[Is body mass index a prognostic factor of survival in colonic cancer? A multivariate analysis].

Introduction: The long-term survival of patients operated on for colonic cancer depends on many factors. Obesity decreases the life expectancy of the general population who suffer from it, but it is not clear whether obesity, measured by the Body Mass Index (BMI), is a prognostic factor of survival for patients operated on for colonic cancer.

Material And Methods: The patients included in this study had TNM stage I, II y III, and were subjected to elective surgery for cancer of the colon in the Girona University Hospital between 1990 and 2001.
