The American Cancer Society (ACS) has guidelines on nutrition and physical activity for cancer survivors that focus on healthy body weight, physical activity, and a diet high in vegetables, fruits, and whole grains. To assess how adherence to those guidelines impacts disease-free survival (DFS), relapse-free survival (RFS), or overall survival (OS), researchers conducted a prospective study of 992 patients with stage III colon cancer who enrolled in an adjuvant chemotherapy clinical trial between 1991 and 2001. The researchers presented the study at the ASCO Annual Meeting.
