Nutrition intervention: Initially, a nutritionist will perform a medical and biological examination of the nutritional status to provide individualized care to each patient. Individual protein requirements will be calculated as 1.2 g of protein per kilogram of body weight (adjusted body weight was used for obese patients), as per European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines, regarding surgical patients (12). Patients will be asked to consume the protein supplement within one hour of their exercise regimen to capitalize on postexercise muscle protein synthesis (13). Then, a dietician will assess the compliance of the nutritional support at each cycle of chemotherapy and will adjust it if necessary. After the preoperative chemotherapy, a second evaluation by a nutritionist will be performed.
