Filter by:Lymph node positive patients after D2 radical surgery for gastric cancer, who started to be treated at Yixing people's Hospital in April 2021, were selected and enrolled into the study group according to the patients' wishes: immune (tirelizumab) combined with chemotherapy (XELOX regimen) or control group: chemotherapy alone (XELOX regimen). Each enrolled patient signed an informed consent form approved by the ethics committee, signed, and dated. Efficacy and adverse effects were assessed in both groups.
The goal of this study is to evaluate the consistency between in vitro tumor organoid drug sensitivity and the therapeutic efficacy of in vivo drug treatment. Participants are required to provide one of fresh tumor tissues (including ascites, pleural effusion, biopsy tissues, palliative surgery specimens, etc.) for the purpose of culturing tumor organoids.
This phase II trial compares atezolizumab in combination with chemotherapy (docetaxel, oxaliplatin, leucovorin calcium, fluorouracil, capecitabine) to atezolizumab alone for controlling the growth and/or spreading of the disease in patients with gastric or gastroesophageal junction (JEG) cancer that has not spread from where it first started (local) or only has spread to nearby lymph nodes or tissue (locoregional) and has high microsatellite instability (MSI-H) and mismatch repair deficiency (dMMR). The mismatch repair (MMR) system in the body corrects errors made during the copying of DNA and serves as a proofreading function. If this system isn't working correctly, mutations (changes) in DNA occur which can allow the cancer to grow or spread. This is called dMMR (deficient mismatch repair) . MSI-H describes cancer cells that have a high number of mutations within microsatellites. For example, microsatellite testing that shows mutations in 30% or more microsatellites is called microsatellite instability-high (MSI-H). Microsatellites are short, repeated sequences of DNA. There is evidence that MSI-H/ dMMR gastric or GEJ tumors respond well to immunotherapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Oxaliplatin is in a class of medications called platinum-containing antineoplastic agents. It damages the cell's DNA and may kill tumor cells. Capecitabine is in a class of medications called antimetabolites. It is taken up by tumor cells and breaks down into fluorouracil, a substance that kills tumor cells. Chemotherapy drugs such as leucovorin calcium and fluorouracil work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Using atezolizumab as immunotherapy with and following chemotherapy versus atezolizumab alone prior to and after surgery may shrink or stabilize the tumor in patients with MSI-H/dMMR localized gastric or GEJ cancer and may increase the length of time after treatment that cancer does not come back or get worse.
Gastric cancer patients after total gastrectomy will be randomized to oral nutritional supplement group or control group at discharge. Patients will receive 6 months of oral nutritional supplement or normal diet after discharge. The primary and secondary outcomes will be collected.
The goal of this cross-sectional study is to evaluate epigenetic modifications in gastric carcinogenesis, mainly in H. pylori gastritis vs gastric carcinoma. The main question[s] it aims to answer are: - How does H. pylori infection cause gastric cancer? - Can DNA methylation and other epigenetic changes predict and affect the development of gastric cancer? Formalin-fixed-paraffin-embedded tissue specimens will be obtained and reviewed for comparison between epigenetic changes in H. pylori gastritis and gastric adenocarcinoma.
This trial is an open-label, multicenter, first-in-human dose-escalation and cohort expansion Phase I/II clinical study to evaluate the safety, tolerability and preliminary efficacy of IMM2902 in the treatment of HER2-expressing advanced solid tumors
To determine the long term outcomes of Endoscopic Submucosal Dissection (ESD), Endoscopic Full Thickness Resection (EFTR) and Submucosal-Tunnelling Endoscopic Resection (STER) for upper gastrointestinal neoplastic lesions
This phase Ib trial test effects of aldesleukin in combination with nivolumab and standard chemotherapy in treating patients with gastric cancer that has spread to the tissue lining of the abdomen (peritoneal metastasis). Aldesleukin is similar to a protein that naturally exists in the body that stimulates the immune system to fight infections. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as leucovorin calcium, fluorouracil, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving aldesleukin in combination with nivolumab and standard chemotherapy may work better in treating patients with gastric cancer with peritoneal metastasis.
In this study, the investigators evaluate the effect of total intravenous anesthesia using sufentanil-remimazolam and remifentanil-remimazolam on postoperative pain in patients undergoing laparoscopic gastrectomy.
The purpose of this early proof-of-concept study to evaluate the safety and immunologic efficacy of AST-301 in gastric cancer patients with HER2 expression (including both HER2 low expression and overexpression) who have completed the standard adjuvant treatment (including those who discontinued the standard adjuvant treatment due to intolerance). Participants will be randomized 1:1 to either Arm 1 (Q3W, 3 cycles), or Arm 2 (Q3W, 6 cycles) of the study. Safety Monitoring Committee (SMC) will oversee safety of study at 25% (6 participants), 50% (12 participants), and 75% (18 participants) of participants receive at least 1 dose of AST-301 and survival follow up will be performed to determine disease-free survival (DFS).
