Filter by:It is very significant that assessing staging in gastric cancer patients before surgery, furthermore, determining the optimize surgical strategy ,predict the the efficacy of neoadjuvant therapy for patients. For patients who are ineffective in neoadjuvant therapy, surgery will be more meaningful. It has been reported that the application of CT(computed tomography,CT) and MR(magnetic resonance,MR) in staging of gastric cancer, but not in predicting clinical response to neoadjuvant therapy for gastric cancer. Only a few studies focused on T staging using conventional MRI in gastric cancer, however , relatively new sequences in the chest deserve widely used. To develop a pre-treatment evaluation methods for TN staging in patient with gastric cancer by utilization of the new imaging methods (T2-TSE-BLADE,T2 maps, StarVIBE, iShim-DWI and high resolution CT). By analysing the relationship between TN staging and imaging features to find the imaging characteristics for TN staging, and to find the indicators of new technology and reference values for facilitate pre-treatment diagnosis of TN staging, optimize surgical strategy , predict the the efficacy of adjunctive therapy , and OS and define the range of lymph node for radiotherapy , as making personal treatment planning for gastric cancer .
The study is aimed to determine the potential of volatile marker testing for gastric cancer screening. The study will be addressing the role of confounding factors, including lifestyle factors, diet, smoking as well as addressing the potential role of microbiota in the composition of exhaled volatile markers.
This phase I trial studies the best dose of sonidegib when given together with pembrolizumab and to see how well they work in treating patients with solid tumor that has spread to other places in the body (advanced). Sonidegib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving sonidegib and pembrolizumab may work better than standard treatment in treating patients with advanced solid tumors.
At the cellular and animal level, we found that propranolol can inhibit the proliferation and invasion of gastric cancer cells. Further, we want to explore the efficacy and safety of propranolol in the treatment of gastric cancer patients.
AZD8186 is an orally-dosed, selective Phosphatidylinositol 3-kinase (PI3K) β/δ inhibitor that binds to PI3Kβ and PI3Kδ, and inhibits kinase activity and downstream pathways in vitro and in vivo. AZD8186 has shown significant anti-tumor activity in PTEN-deficient preclinical models, including prostate, triple negative breast cancer, squamous lung and germinal center diffuse large B-cell lymphoma models. PTEN deficiency is reported in approximately 20% of patients with gastric cancer and in 35-48% of those with human epidermal growth factor receptor 2(HER2)-positive gastric cancer. To date, there have been no clinical trials with AZD8186 alone or in combination with paclitaxel in advanced gastric cancer. Therefore, it is very important to conduct clinical trials of combination therapy of AZD8186 and paclitaxel in patients with metastatic/recurrent gastric cancer who have failed previous therapy, and to identify the clinical factors and biomarkers that predict effects of the combination therapy. The purpose of the study is to define the maximal tolerated dose (MTD) and recommended phase 2 dose (RP2D) of paclitaxel and AZD8186 combination therapy in patients with advanced tumors and to evaluate the efficacy of paclitaxel and AZD8186 combination therapy as a second-line therapy in patients with advanced gastric cancer with PTEN aberrations. This study is divided into Phase 1b and Phase 2.
This study is designed to evaluate the potential clinical utility of ctDNA in the field of gastric cancer treatment,especially the usage of an indicator of MRD(minimal residual disease) in post radical gastrectomy patients. The primary purpose of this trial is to demonstrate if the postoperative ctDNA analysis could be used as an indicator of MRD or adjuvant chemotherapy response in advanced gastric cancer after radical gastrectomy.The second purpose is to describe the profile of ctDNA in gastric cancer.
The purposes of this study are to collect and store samples including blood, normal and tumor tissue from patients with colorectal cancer or gastric cancer, to collect and store samples including blood and/or normal gastrointestinal tissue (if available) from patients with non-malignant disease (including, but not limited to, inflammatory bowel disease (IBD), gastric ulcer, hemorrhoids or hernia), and to create a database for the collected samples and allow access to relevant clinical information for current and future protocols.
S-1 plus oxaliplatin has been proved better than S-1 alone for stage II or III gastric cancer. Docetaxel also showed excellent efficacy with S-1 in the postoperative setting for stage III gastric cancer. This trial is designed to investigate the efficacy and safety of S-1 plus docetaxel versus S-1 plus oxalipltin as adjuvant chemotherapy after D2 resection in stage II / III gastric cancer.
In this study the patients with histological evidence of adenocarcinoma of the stomach will be screened and, if eligible, submitted to neo-adjuvant chemotherapy (NAC). After conclusions of NAC and obtaining informed consent, they will be registered and randomized to receive surgical D2 vs. D2plus lymphadenectomy.
To explore the clinical value of dynamic detection of circulating tumor cells(CTCs), circulating tumor DNA(ctDNA) and cell-free DNA(cfDNA) in neoadjuvant chemotherapy and operation of resectable or locally advanced gastric or gastro-oesophageal junction cancer.
