The Influence of Body Mass Index on Overall Survival Following Surgical Resection of Non–Small Cell Lung Cancer

This retrospective study of the association of BMI to long-term survival after resection of NSCLC identified BMI > 30kg/m2 as an independent predictor of survival.  In a propensity score matched set, patients with BMI >30 had better survival than those with a BMI of 25 (p=0.003).   The reason for this relationship remains to be elucidated.
