Overview
Cancer patients undergoing surgery are at high risk of malnutrition due to the effects of the tumor and surgical stress, which can lead to worse clinical outcomes. This study aims to evaluate the impact of beta-hydroxy-beta-methylbutyrate (HMB) supplementation on inflammatory markers and clinical outcomes in patients with malignant tumors of the upper airways and digestive tract undergoing surgery.
This is a randomized, double-blind clinical trial. Participants will be randomly assigned to one of two groups: intervention (3 g/day of HMB) or control (3 g/day of maltodextrin) for 30 days prior to surgery. Initial assessments will include nutritional status, muscle strength, quadriceps muscle thickness by ultrasound, and laboratory tests. Postoperative clinical outcomes will be monitored through electronic medical records.
