Effects of Protein on Muscle, Gut Microbiota and Clinical Outcome in Patients With Lung Cancer-related Sarcopenia

Sarcopenia is common in lung cancer patients. It is one of the significant factors affecting the overall survival, radiotherapy and chemotherapy efficacy, and quality of life of patients with lung cancer. Previous studies have shown that increased protein intake can stimulate postprandial muscle synthesis, and improve muscle mass, strength, function, and overall survival. However, most previous studies have focused on the intervention of whey protein, while the protective effect of soybean protein on lung cancer-related sarcopenia (LCRS) has not yet been fully explored and reached an agreement. So, this study aims to explore the effects of soy and whey protein on muscle, gut microbiota, and clinical outcomes among patients with lung cancer-related sarcopenia, to provide a reference for further nutrition treatment.
