Association of Diet Quality With Survival Among People With Metastatic Colorectal Cancer in the Cancer and Leukemia B and Southwest Oncology Group 80405 Trial

Key Points Question Is diet quality at initiation of first-line treatment for metastatic colorectal cancer associated with overall survival? Findings In this cohort study including 1284 people with metastatic colorectal cancer enrolled between 2005 and 2012, diet quality (assessed by the Alternative Healthy Eating Index, Alternate Mediterranean Diet score, Dietary Approaches to Stop Hypertension diet score, a Western dietary pattern, and a prudent dietary pattern) was not associated with overall survival after a median follow-up of 73 months. Meaning The results of this study suggest that overall diet quality assessed at initiation of first-line treatment for metastatic colorectal cancer was not associated with overall survival.
