The Impact of Body Mass Index on the Surgical Outcomes of Patients With Gastric Cancer A 10-Year, Single-Institution Cohort Study

摘要

This study aimed to investigate the impact of body mass index (BMI) on the short-term and long-term results of a large cohort of gastric cancer (GC) patients undergoing gastrectomy. Recently, the "obesity paradox" has been proposed, referring to the paradoxically "better" outcomes of overweight and obese patients compared with nonoverweight patients. The associations between BMI and surgical outcomes among patients with GC remain controversial.
