Material/Methods: From July-2023 to Octubre- 2024 we conducted a prospective study in 100p with ECOG≤2 admitted to our ORTW. Patient characteristics are shown in Figure 1. Tumor stages: I (13%), II (12%), III (27%) and IV (48%). Mean age: 68y (33-90). Average hospital stay: 8d (1-43). Most frequent cause-of-admission: poor-pain-control (24%), respiratory infections (21%) and neurological symptoms (7%). QoL: EORTC QLQ-C30 questionnaire. NS assessment: MUST scale. Statistics: t-test, chi-square, Kaplan-Meier. Results: Mean hospital stay: 8,69 days (1-43). Median weight: 70kg (46-130). Low-risk malnutrition (MUST<2) was observed in 89% and high- risk (MUST ≥ 2) in 11%. At hospital discharge, nutritional supplements and exercise were prescribed in 25% of patients. No significant differences were registered in length of hospital stay between patients with MUST≥2 and MUST<2 (38 days vs 13 days pNS). There was an improvement in Global-Health-Status score from 29 at admission to 41 at discharge, with statistical significance (p<0.01). NS did not influence QoL (global health score of 28 vs 34 for patients with MUST < 2 and MUST ≥ 2, p=0.94) (Figure 2).
