Brief summary

The goal of this clinical trial is to investigate the effects of a perioperative multimodal rehabilitation program on the incidence of postoperative complications and perioperative clinical indexes including functional capacity, nutritional and psychological status in patients with gastric cancer undergoing neoadjuvant therapy. Besides the investigators also develop a smart phone based digital platform aiming to evaluate its effectiveness in improving patient adherence, compared with the conventional telephone supervision approach. The main questions it aims to answer are: * Can the perioperative multimodal rehabilitation program reduce postoperative complications in patients with gastric cancer undergoing neoadjuvant therapy? * Can the smart phone based digital platform improve patients' adherence compared to traditional telephone supervision? * Can the perioperative multimodal rehabilitation program improve the perioperative clinical indicators of patients with gastric cancer undergoing neoadjuvant therapy, including functional capacity, nutritional status and psychological condition? The investigators will compare the perioperative multimodal rehabilitation program with the standard treatment alone to determine whether this program has the effects mentioned above. Participants will follow the perioperative multimodal rehabilitation program from neoadjuvant therapy through to four weeks after discharge.

Interventions

BEHAVIORALperioperative multimodal rehabilitation program with telephone supervision

The perioperative rehabilitation program in this study constitutes a multimodal intervention that integrates exercise, nutrition, and psychological support. The exercise component consists of aerobic training five times per week, elastic band-based resistance training twice per week, daily respiratory muscle exercises, and post-exercise stretching routines. For nutrition, daily targets are set at 25-30 kcal/kg for energy and 1.5 g/kg for protein intake based on ideal body weight, supported by standardized meal plans and nutritional reference materials. The psychological intervention includes weekly motivational videos and psychoeducational content, supplemented by regular assessment of emotional and cognitive status using validated scales. Patients independently follow the program, and record all activities in a rehabilitation diary, which will be returned post-trial.Additionally, patients will receive a weekly telephone call, to assess adherence to the program.

PROCEDUREUsual Care

Patients receive usual care throughout their cancer pathway. Besides, we will provide verbal exercise, dietary, and psychological advice to patients but did not provide written advice and supervision.

Nutritional status--(2)skeletal muscle index(SMI)From enrollment to 1 year postoperativelyAs part of standard care, patients undergo CT imaging at baseline, following neoadjuvant therapy, and during postoperative follow-up. Sarcopenia is measured at these time points using ImageJ software. At the L3 level, total skeletal muscle, subcutaneous fat and visceral fat will be measured. SMI will be calculated as follows: skeletal muscle /height(m)2. Measurements will be recorded by two individuals, one of whom will be external to the trial group.
Nutritional status--(3)mid-upper arm circumference(MUAC)From enrollment to 1 year postoperativelyPatients stand upright with shoulders relaxed and the right arm hanging naturally. The assessor, positions to the participant's right, wraps a measuring tape around the midpoint between the acromion and olecranon processes, ensuring it remains perpendicular to the long axis of the arm. The tape is held snug but without compressing the underlying soft tissue. The measurement is taken on the lateral aspect of the arm, with the zero end of the tape aligned under the measurement mark.
Nutritional status--(4)triceps skinfold thickness(TSF)From enrollment to 1 year postoperativelyTSF is measured at the same marked midpoint on the right upper arm as MUAC. With the patients standing, a vertical skinfold parallel to the arm is gently grasped above the mark. A caliper is applied perpendicular to the fold, and the thickness is recorded to the nearest 0.1 mm before release.
Nutritional status--(5)insulin resistance(IR)From enrollment to 1 year postoperativelyIR will be measured using the homeostasis model assessment(HOMA) calculation. HOMA-IR = (fasting glucose × fasting insulin) / 22.5.

Psychological scale scores--(1)Hospital Anxiety and Depression Scale (HADS)From enrollment to 1 year postoperativelyIt is a 14 item self report instrument comprising two 7 item subscales designed to screen for symptoms of anxiety and depression in non psychiatric medical settings. Each subscale is scored separately, providing independent measures of anxiety and depressive symptomatology while minimizing confounding from physical illness. Each item is scored from 0 to 3, with subscale scores ranging from 0 to 21. Higher scores indicate greater levels of anxiety or depression. The scale has been validated and demonstrates good reliability in clinical populations.
Psychological scale scores--(2)Life Orientation Test Revised (LOT-R)From enrollment to 1 year postoperativelyIt comprises 10 items evaluating an individual's expectancies for positive versus negative future experiences. Each item is scored on a 5-point scale (0-4). After reverse-scoring pessimism items, total scores range from 0 to 24, with higher scores indicating greater optimism.
Psychological scale scores--(3)General Self Efficacy Scale (GSE)From enrollment to 1 year postoperativelyIt is a 10-item psychometric instrument designed to assess optimistic self-beliefs in one's ability to cope with a wide range of difficult life demands. It is a well-validated and highly reliable measure of generalized self-efficacy. Each item is scored on a 4-point scale (1-4). Total scores range from 10 to 40, with higher scores indicating greater self-efficacy.
Psychological scale scores--(4)EuroQol 5 Dimension 5 Level (EQ-5D-5L)From enrollment to 1 year postoperativelyIt is a standardized, generic instrument developed by the EuroQoL Group to measure health status. It provides a concise profile of health outcomes designed for use in both clinical studies and health economic evaluations. It includes five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension comprises five levels of perceived problems, ranging from no problems to extreme problems. Responses are summarized as a five-digit health profile, which can be converted into a utility index score, typically ranging from 0 to 1, with higher scores indicating better health status.
Psychological scale scores--(5)Pearlin Mastery Scale (PMS)From enrollment to 1 year postoperativelyIt is a 7-item scale developed to measure psychological coping resources, specifically an individual's sense of mastery or perceived control over life circumstances. It is also a validated and reliable tool. Each item is scored on a 4-point scale (1-4). Total scores range from 7 to 28, with higher scores indicating greater perceived mastery or sense of control.
Psychological scale scores--(6)Surgical Fear Questionnaire (SFQ)From enrollment to the day before surgery, assessed up to 100 daysIt is an eight-item instrument designed to assess fear related to surgery. It consists of two subscales measuring fear of short-term and long-term surgical consequences, and has been validated as a reliable index of surgical fear. Each item is scored on an 11-point scale (0-10). Subscale scores range from 0 to 40, and total scores range from 0 to 80. Higher scores indicate greater surgical fear.
Gastric emptying functionFrom the time of surgery to 90-day postoperativeIt is evaluated by gastric emptying half-time (GET₁/₂) measured via radionuclide scintigraphy.
