Filter by:Approximately 5% to 10% of gastric cancers have MSI-H/dMMR. According to the results of retrospective analysis of CLASSIC and MAGIC, MSI-H/dMMR was a good prognosis and potential negative predictor of adjuvant chemotherapy for resectable gastric cancer. GC patients with MSI-H/dMMR were relatively insensitive to chemotherapy. The prognosis of these patients receiving routine postoperative adjuvant chemotherapy was worse than that with surgery alone. However, these patients were sensitive to immunotherapy. MSI-H/dMMR is one of the most important biomarkers to predict the efficacy of immunotherapy for GC. In this study, patients with MSI-H locally advanced gastric adenocarcinoma after radical surgery with D2 dissection would be randomly treated with conventional adjuvant chemotherapy, PD-1 monoclonal antibody immunotherapy or follow-up observation. We intend to demonstrate that the prognosis of MSI-H GC patients after D2 radical gastrectomy receiving PD-1 monoclonal antibody immunotherapy would be better than that with standard postoperative adjuvant chemotherapy and follow-up observation.
To observe and determine the safety, tolerability, cellular pharmacokinetics and efficacy of TCRx T cells in patients with advanced or recurrent gastric/gastroesophageal junction cancer after failure of first chemotherapy.
In this study, patients with traditional neoadjuvant gastric cancer were used as controls to explore whether the triple pre-rehabilitation interventions of exercise, nutrition and psychology during the neoadjuvant period before surgery could improve the functional reserve of neoadjuvant gastric cancer patients and accelerate postoperative recovery.
Early gastric cancer(AGC)has no effective characteristic symptoms and signs according to clinical statistics. Neoadjuvant chemotherapy (NAC) significantly reduces the size of AGC tumors so that it has become the recommended treatment for AGC in major guidelines. However, Some patients miss the best time for surgical treatment and may have irreversible chemotherapy side effects due to NAC lacks the guidance of new indicators for precise treatment such as molecular biomarkers. Tumor organoids are highly consistent with the clinical drug sensitivities of patients which could be used as clinical treatment prediction models thus providing guidance for individualized medicine. Therefore, the project is the first to carry out the prospective study by screening the potential benefit populations of NAC based on tumor organoids drug susceptibility experiment. The following hypothesis are put forward:the potential benefit population of NAC screened by tumor organoid drugs susceptibility technology will have better clinical efficacy, better treatment tolerance and higher adverse reaction rate.
The purpose of this study was to evaluate the efficacy of camrelizumab combined with nab-paclitaxel intraperitoneal infusion, intravenous chemotherapy and S-1 in the treatment of advanced gastric cancer with peritoneal metastasis, so as to preliminarily explore the feasibility of the three-drug combination regimen in patients with gastric cancer with peritoneal metastasis and safety, and strive to maximize the benefits of different groups of people.
The purpose of this study is to assess the dosimetric properties of the positron emission tomography (PET) imaging probe 68Ga labeled HER2 Affibody analogues and preliminarily evaluate its diagnosis value in patients with breast or gastric tumors.
The purpose of this study is to investigate the efficacy and safety of intraperitoneal and intravenous nab-paclitaxel plus Camrelizumab and S-1 conversion therapy for gastric cancer with positive exfoliative cancer cells.
This is a prospective pilot study to evaluate the safety and feasibility of neoadjuvant transcatheter infusion and embolism (TACiE) in patients with locally advanced adenocarcinoma of stomach and gastroesophageal junction. The TACiE protocol includes four cycles. Transcatheter oxaliplatin and concurrent embolism on day 1 and oral S-1 on day 1-14 will be administrated in the first and third cycles. Intra-venous oxaliplatin on day 1 and oral S-1 on day 1-14 (SOX) will be administrated in the second and fourth cycles.
There are still some unsolved questions regarding population-based screening program for H. pylori infection to prevent gastric cancer, such as how to perform the optimal screening strategies. A prospective, randomized trial will be conducted to compare the acceptability, compliance (/adherence), and accuracy of diagnostic tests in a population-based H. pylori screening and gastric cancer prevention program. The investigators will recruit 10,000 adults with age of ≥20 years who have not received H. pylori screening or treatment. Eligible patients will be randomly 1:1:1:1 allocated to four groups with different combination tests.
An exploratory study of pembrolizumab combined with anlotinib and chemotherapy in the perioperative treatment of locally advanced gastric cancer
