QL1706-SOX vs SOX Alone as Neoadjuvant Therapy for Resectable Diffuse-Type Gastric Cancer

The goal of this randomized, open-label, phase II clinical trial is to determine whether adding the PD-1/CTLA-4 bispecific antibody QL1706 to standard SOX chemotherapy increases the pathological complete response rate in adults aged 18-75 years with resectable, locally advanced, diffuse-type, HER2-negative gastric adenocarcinoma (cT3-4aNxM0). Participants will be randomly assigned (1:1) to receive 3-4 neoadjuvant cycles of QL1706 plus SOX or SOX alone every 3 weeks, followed by curative-intent gastrectomy with D2 lymphadenectomy, and will be monitored post-operatively every 3 months for 2 years and every 6 months thereafter for recurrence, survival, and safety.

A Randomized Controlled Study of Serplulimab Combined With Chemotherapy for Locally Advanced Gastric Adenocarcinoma

The goal of this clinical trial is to learn if FLOT chemotherapy combined with serplulimab can improve the pathological complete response (pCR) rate in patients with stage III gastric cancer. The main question it aims to answer is: Can FLOT chemotherapy combined with serplulimab improve the pathological complete response (pCR) rate in patients with stage III gastric cancer? Researchers will compare serplulimab with a blank control group to see if it can improve the pathological complete response (pCR) rate in patients with stage III gastric cancer. Participants will : Receive serplulimab combined with FLOT chemotherapy or FLOT chemotherapy alone every 2 weeks Undergo imaging assessments at 4 weeks and 8 weeks Undergo surgery based on imaging results after 8 weeks Receive postoperative serplulimab combined with adjuvant chemotherapy or adjuvant chemotherapy alone

Omega-3 Supplementation and Immunotherapy in Gastric Cancer: A Phase II Trial

The goal of this clinical trial is to learn if Omega-3 fatty acids supplementation can enhance the efficacy of neoadjuvant immunotherapy in patients with locally advanced gastric and gastroesophageal junction adenocarcinoma. The main questions it aims to answer are: does Omega-3 supplementation improve the pathologic complete response (pCR) rate compared to standard neoadjuvant immunotherapy alone, and is there an increase in the major pathological response (MPR) rate with Omega-3 supplementation? Researchers will compare the group receiving Omega-3 supplementation with the control group receiving standard neoadjuvant immunotherapy to see if Omega-3 supplementation leads to better treatment outcomes. Participants will receive Omega-3 fatty acids supplements in conjunction with their prescribed neoadjuvant immunotherapy, undergo regular assessments of their pathologic response to treatment, and provide information on their nutritional status and quality of life throughout the study.

Using ctDNA to Guide Treatment Decisions for Stage III Gastric Cancer

The goal of this randomized, controlled phase III clinical trial is to evaluate whether combining Tislelizumab with standard SOX chemotherapy improves disease-free survival (DFS) compared to chemotherapy alone in patients with stage III gastric or gastroesophageal junction adenocarcinoma who are ctDNA-MRD positive after surgery. The study will enroll 416 patients across multiple centers and will compare outcomes between two groups: patients receiving tislelizumab plus SOX chemotherapy and those receiving standard SOX chemotherapy alone. The primary questions to be addressed are whether the combination therapy improves 1-year DFS rates and whether it demonstrates an acceptable safety profile. Participants will provide tissue and blood samples for ctDNA-MRD testing, undergo postoperative adjuvant therapy (chemotherapy ± immunotherapy), and complete regular follow-up visits to monitor treatment response and safety. The trial will assess key outcomes, including DFS, overall survival (OS), and ctDNA clearance rates, to determine the clinical benefit and safety of tislelizumab in this population.

Investigation of Impact of Indocyanine Green on Volume of Lymphadenectomy in Resectable Gastric Cancer

The study aims to evaluate the safety and benefits of using indocyanine green in lymph node dissection for gastric cancer surgery. The primary endpoint is the average number of lymph nodes removed. Secondary study points are the average number of ICG-positive lymph nodes; the average number of metastatic ICG-positive lymph nodes; the number of postoperative complications and complications associated with the administration of ICG. Patients who meet the inclusion criteria for this study will be enrolled in the study after reviewing and signing an informed consent form. All patients will be included in one group and will receive surgical treatment in the amount of total or subtotal gastrectomy with lymphadenectomy D1, D1+, D2 or D2+. ICG is injected by the patient by endoscopic submucosal injection into 4 points around the tumor 24-12 hours before the start of the surgical intervention. Assessment of the number of fluorescent lymph nodes will be performed intraoperatively with their subsequent removal and mapping. The incidence of postoperative complications will be assessed by Clavien-Dindo.

Adjuvant Chemotherapy in Combination With Camrelizumab for Stage III Gastric Cancer (FOCUS-02)

This study is a prospective, single arm, multi-center phase II clinical trial. The primary study objective is to evaluate the safety of tegafur gimeracil oteracil potassium capsule plus oxaliplatin and Camrelizumab as adjuvant therapy in stage III gastric cancer, including the incidences and types of adverse events. The secondary study objective is to observe and evaluate the disease-free survival (DFS), overall survival (OS) and treatment completion rate.

A Multicenter, RCT Study of the Clinical Efficacy of Robotic and Laparoscopic Gastrectomy in Neoadjuvant Gastric Cancer

To evaluate the clinical efficacy of robot radical Gastrectomy and laparoscopic radical Gastrectomy, patients with gastric adenocarcinoma (cT2N+M0 or cT3-4a/N+M0, phase II and III) undergoing neoadjuvant treatment were selected as subjects.
