TEAS Timing for Gastrectomy Recovery (TEAS-TIME Trial)

The goal of this clinical trial is to learn if transcutaneous electrical acupoint stimulation (TEAS) works to help people recover faster after laparoscopic surgery for stomach cancer. TEAS is a treatment that uses small electrical pulses through sticky pads on the skin. It does not use needles. The main questions it aims to answer are: Does TEAS help people pass gas (a sign that the digestive system is waking up) sooner after surgery? Does TEAS help lower pain after surgery? Does TEAS reduce the need for extra pain medication after surgery? Researchers will compare three groups to see if TEAS works better when given before, during, and after surgery compared with only after surgery. Group 1 receives TEAS before, during, and after surgery. Group 2 receives a sham (inactive) treatment before and during surgery, and real TEAS after surgery. Group 3 receives sham treatment at all time points. All participants will receive the same standard pain relief and recovery care after surgery. Participants will: Be randomly assigned (like flipping a coin) to one of the three groups Receive TEAS or sham treatment for 30 minutes before surgery, during surgery, and for 30 minutes each day on the first 3 days after surgery Rate their pain on a 0-10 scale at 6, 12, 24, 48, and 72 hours after surgery Complete quality-of-life questionnaires before surgery, on day 4 after surgery, and 30 days after surgery Have a follow-up visit or phone call 30 days after leaving the hospital This study includes 300 adults aged 18 to 80 years who are scheduled to have laparoscopic surgery for stomach cancer at 13 hospitals in Shandong Province, China.

Longitudinal Geriatric Vulnerability, Chemotherapy Toxicity, and Functional Outcomes in Older Adults With Gastrointestinal Cancer

Older adults with gastrointestinal cancers may be more likely to experience side effects from chemotherapy and difficulties with everyday activities. These problems are not always explained by age alone. Changes in nutrition, physical strength, general health, and independence may also affect how well a person tolerates cancer treatment. The purpose of the VITAL-GI study is to better understand how health-related vulnerability in older adults is associated with chemotherapy side effects and changes in daily functioning over time. This is an observational study involving adults aged 65 years or older with gastrointestinal cancer that has not spread to distant parts of the body. Participants receive chemotherapy as part of their usual medical care, either before or after surgery, according to their treatment plan. The study does not assign chemotherapy treatments or change routine care. Researchers use questionnaires and clinical information to assess general health, nutrition, physical abilities, independence, and the risk of chemotherapy side effects. Assessments are performed when chemotherapy begins and approximately 3 and 6 months later. The study examines whether initial health assessments can help identify people who are more likely to experience serious chemotherapy side effects. It also examines how health, daily activities, symptoms, and quality of life change during treatment. The findings may help researchers better understand the supportive care needs of older adults receiving chemotherapy for gastrointestinal cancer.

Multimodal Prehabilitation in Gastric Cancer Patients

This single-arm phase II trial investigates whether a multimodal prehabilitation program can attenuate the postoperative inflammatory response in patients undergoing curative gastric cancer surgery. Major abdominal surgery induces a pronounced systemic inflammatory reaction that contributes to postoperative complications, delayed recovery, impaired functional status, and reduced tolerance to adjuvant therapy. Elevated postoperative C-reactive protein (CRP) trajectories have been associated with infectious complications, whereas a timely decline in CRP may reflect a more adequate immune response. Interventions that improve nutritional status, physical fitness, and psychological resilience before surgery may modulate these inflammatory processes. The PING-P intervention combines three components starting two weeks before surgery and continuing for three weeks postoperatively: (1) structured exercise including resistance, aerobic and respiratory training supported by pulsed electromagnetic field (PEMF) therapy to both thighs twice weekly; (2) individualized nutritional therapy with counseling and provision of omega-3-enriched high-protein oral nutritional supplements twice daily to achieve ≥1.2 g/kg/day protein intake; and (3) psychological support using coaching and digital relaxation tools. The program is delivered in hospital and at home using a mobile application with regular monitoring and feedback. The primary objective is to evaluate whether this multimodal approach reduces the proportion of patients with a poor postoperative immune response, defined as either a CRP peak ≥166 mg/L or a decrease from peak CRP to two days later of \<35%. CRP will be measured from postoperative day (POD) 1 to POD7 or until discharge. Secondary objectives include assessment of feasibility (recruitment, retention, and adherence to ONS intake, PEMF sessions, and exercises), postoperative infectious and overall complications, intervention-related adverse events, functional recovery, nutritional status, body composition, and quality of life. Adults with histologically proven gastric or esophagogastric junction cancer (Siewert II-III) scheduled for minimally-invasive curative gastrectomy at National University Hospital and Ng Teng Fong General Hospital, Singapore, will be enrolled. Exclusion criteria include distant metastases, emergency surgery, need for preoperative tube or parenteral feeding, inability to follow the program, or contraindications to oral nutrition. A total of 25 participants will be recruited. The study will provide first data on whether targeted multimodal prehabilitation can favorably modify perioperative inflammation and inform the design of a future randomized trial.
