To the Editor: Dr Meyerhardt and colleagues1 presented data from the Cancer and Leukemia Group B (CALGB) chemotherapy trial (CALGB 89803) indicating that dietary patterns were associated with differences in recurrence and survival in patients with colon cancer. Body mass, a rough integration of diet and activity, is a simpler end point to measure and is associated with increased incidence of colorectal adenomas and cancer.2,3 Body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) is also associated with prognosis after adjuvant treatment.4
