Effect of Pre-habilitation Combined With Enhanced Recovery After Surgery (ERAS) Versus ERAS Perioperative Management on Clinical Outcomes of Laparoscopic (Robotic) Gastrectomy in Patients With Gastric Cancer Receiving Neoadjuvant Chemotherapy: A Single-center Randomized Controlled Trial

The study is designed as a prospective, single-center, randomized, open-label, controlled clinical trial to compare the effects of pre-habilitation combined with ERAS versus ERAS alone in patients undergoing laparoscopic (robotic) gastrectomy after neoadjuvant chemotherapy for gastric cancer. The study will enroll patients aged 18-75 years who are scheduled for laparoscopic (robotic) gastrectomy following neoadjuvant chemotherapy. Participants will be randomly assigned in a 1:1 ratio to either the pre-habilitation plus ERAS group or the ERAS group. The pre-habilitation program will include a 4-week intervention involving exercise, nutrition, and psychological support prior to surgery. The primary endpoint is the incidence of postoperative complications within 30 days, assessed using the Clavien-Dindo classification. Secondary endpoints include pathological characteristics, surgical outcomes, patient-reported outcomes, and long-term survival rates. Data will be collected from patient records and follow-up visits. Statistical analysis will be performed using SPSS 26.0 or later versions, with significance level set at α=0.05.
