Phase angle, body mass index and KRAS status of metastatic colorectal cancer in response to chemotherapy with and without target therapy: clinical impact and survival.

Purpose: KRAS mutations are associated with colorectal cancer survival whereas the role of body mass index (BMI) is less defined. Phase angle, which is more an indicator of cell integrity also has not been studied as prognostic and predictive factor. We evaluated the association between BMI, phase angle and colorectal cancer overall survival (OS), by KRAS mutation status and other prognostic for metastatic colorectal cancer.
