Malnutrition risk and overall survival at solid tumour diagnosis.

Purpose: Malnutrition severely impacts tolerance to anticancer therapies, but any relationship with overall survival (OS) at the time of solid tumour diagnosis in outpatients in the USA remains unclear.

Methods: This retrospective study evaluated 3562 patients who completed the Malnutrition Screening Tool (MST) at diagnosis, identifying the relationship between MST risk, a validated tool evaluating anorexia and weight loss, and OS. MST score of ≥2 of 5 was classified as high malnutrition risk (H-MST).
