Nutrition impact symptom monitoring and weight loss outcomes: a longitudinal radiotherapy study.

Objectives: Nutrition impact symptoms (NIS) are associated with weight loss (WL), and decreased energy intake in cross-sectional studies. We aimed to ascertain associations between changes in NIS burden, energy intake and WL over time in patients with advanced cancer.

Methods: Adult patients from an observational radiotherapy study for painful bone metastases self-reported NIS and WL using the Patient-Generated Subjective Global Assessment tool (PG-SGA) at baseline and week eight (W8).
