Clinical trials

Gastric cancer is one of the cancers with a high mortality rate globally, and its treatment outcomes urgently need to be improved. The emergence of immunotherapy has broken through the bottleneck of chemotherapy for gastric cancer. However, the therapeutic efficacy of immunotherapy varies significantly among patients and still needs to be enhanced. Extensive research has demonstrated that the efficacy of immunotherapy for gastric cancer is significantly influenced by the tumor microenvironment (TME) and epigenetic modifications. The dynamic changes in tumor-infiltrating lymphocytes (TILs) and histone H3K4me3 may reshape the TME, thereby affecting the efficacy of immunotherapy. Based on these findings, this study proposes the scientific hypothesis that the density and spatial distribution of TILs in the TME, as well as the level of H3K4me3 modification, may serve as key biomarkers for predicting the response of gastric cancer patients to immunotherapy. This project aims to delve into the potential mechanisms by which TILs and H3K4me3 enhance the efficacy of immune checkpoint inhibitors (ICIs) and to construct a predictive model for the response to immunotherapy in gastric cancer based on TILs and H3K4me3. The establishment of this model will help identify the patient population most likely to benefit from immunotherapy, facilitate personalized treatment, provide new ideas and approaches for the treatment of gastric cancer, and advance the field of gastric cancer immunotherapy.

This study is a multicenter, open-label, prospective, randomized parallel-controlled trial. The purpose is to explore whether the incidence rate of reflux esophagitis (RE) within 12 months after surgery is non-inferior for the DFT group compared to the DTR group.

The purpose of this observational study is to evaluate the safety and efficacy of camrelizumab and apatinib in patients with advanced gastric cancer under real-life conditions, particularly in various subgroups of gastric cancer patients, with a view to providing information about the treatment modalities and efficacy of the treatment in real-life gastric cancer patients and to explore the possible predictive biomarkers of prognosis.Patients, who had both decided to be treated with camrelizumab or apatinib prior to enrollment, were entered into one of the following three cohorts at the discretion of the investigator, based on their disease stage and prior treatment

The efficacy of three different reconstruction methods after proximal gastrectomy will be investigated in this study through a prospective, multicenter, randomized controlled trial.
