Family-Supervised Prehabilitation to Reduce Postoperative Complications After Neoadjuvant Chemotherapy in Gastric Cancer

"A comprehensive prehabilitation program initiated at the start of neoadjuvant chemotherapy and continued until the day before surgery. The intervention includes:~1. Nutritional support: individualized dietary counseling and supplementation plans supervised by clinical nutritionists;~2. Exercise training: home-based aerobic and resistance exercises monitored via wearable devices and weekly video/phone follow-ups;~3. Psychological support: structured counseling sessions to reduce anxiety, improve treatment adherence, and enhance quality of life.~Family members are trained to assist with supervision and compliance. The total duration is approximately 10-16 weeks, depending on the chemotherapy schedule."

Standard neoadjuvant chemotherapy followed by radical gastrectomy with standard ERAS-based perioperative management, without any additional prehabilitation intervention. Participants receive routine nutritional, nursing and medical care according to hospital guidelines. The aim is to maintain current clinical practice as the control condition for comparison with the experimental prehabilitation program.
