Perirenal Fat Surface Area and Oncologic Outcome in Elective Colon Cancer Surgery.

Background: Central obesity is associated with surgical difficulties, but few studies explore the relationship with long-term results after colon cancer surgery.

Objective: The purpose of this study was to investigate the association between perirenal fat surface area, a proxy for total visceral fat, and oncologic outcome after intestinal resection for colon cancer.

Design: We investigated the association between perirenal fat surface area (exposure) on recurrence and death (outcome) in patients undergoing surgery with curative intent for colon cancer.
