The Advantages and Disadvantages Between Uncut Roux-en-Y Reconstruction and Billroth II Reconstruction After Laparoscopy-assisted Distal Gastrectomy for Gastric.
This main purpose of this clinical study is to learn about the safety and activity of margetuximab and pembrolizumab combination treatment in patients with HER2+ gastric and gastroesophageal junction cancer.
Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Despite advances in therapeutic intervention, the mortality from this disease remains high. As a result, most patients are now offered varying combinations of surgery, chemotherapy, and radiation therapy in order to derive benefits from a multidisciplinary approach. Unfortunately, therapies are often toxic or debilitating and therapeutic responses can vary. Thus new therapeutic strategy is required for the treatment of gastric cancer. In the early 1980s, the discovery of cytolytic T cells (cytolytic T lymphocytes, CTLs) directed against an antigen presented on tumor cells was published. They can kill many invasive cells by recognizing the tumor specific antigens on the major histocompatibility complex (MHC) molecules. It is now generally agreed that although tumors express tumor antigens, they usually lack immunogenicity because of their inability to activate the immune response. The current view is that tumor cells are antigenic, but not immunogenic. If we can artificially activate the immune system against the tumor, it may be possible to eradicate the tumor. This approach is the basis of cancer immunotherapy. Many tumor antigens have been defined in terms of multiple solid tumors: MART-1/Melan-A, gp100, carcinoembryonic antigen (CEA), HER-2, mucins (i.e., MUC-1), prostate-specific antigen (PSA), and prostatic acid phosphatase (PAP) are just a short list. Some immune-based therapies targeting these tumor antigens are in phase III trials assessing whether immunizing against these antigens affects overall survival. In gastric cancer, some tumor antigens such as MAGE-A3, NY-ESO-1, and WT-1 have been reported to be expressed in substantial proportion of cases. They have the potential to be the targeting molecules for immunotherapy in the future. In this study, we aim to explore the expression levels of the four tumor markers (MAGE-A3, NY-ESO-1, WT-1 and PRAME) in gastric cancers of Korean patients and to examine the correlations of the expression levels of the four markers to clinic-patholoical factors.
After endoscopic resection of early gastric cancer (EGC), there remained concerned about the development of the metachronous gastric neoplasm (MGN). The aim of this study was to evaluate the role of H. pylori eradication for reducing MGN after ESD and the efficacy of serum pepsinogen (PG) for predicting development of MGN after endoscopic submucosal dissection (ESD) for EGC and to evaluate other risk factors for the incidence of MGN. The investigators enrolled the participants who were tested serum PG I and II at the time of ESD for EGC, from January 2007 to May 2013 in single tertiary center, retrospectively. The baseline characteristics of the participants, H. pylori status, and serum pepsinogen were analyzed for the development of the MGN.
The purpose of this study is to determine whether positive lifestyle interventions (diet modification and smoking cessation) are effective in the prevention of gastric pre-cancer and cancer occurrences and reccurence of gastric cancer after endoscopic resection.
The evaluation of the chemotherapy efficacy for gastric cancer patients is usually evaluated by computer tomography scans with RECIST criteria that are performed every two months during the treatment. The management of treatment for gastric cancer needs the development of early biomarkers to evaluate the efficacy in order to avoid unnecessary toxicity in case of early chemotherapy resistance. In this prospective study, we will compare the monitoring of circulating tumor DNA with the results of CT scan according the RECIST criteria and the blood level of CEA and CA 19-9 tumor markers. Thus, the objective of this study is to identify a prognostic and/or predictive biomarker of tumor response according to the tumor DNA circulating assessment in gastric cancer treatment, in order (i) to avoid an unnecessary toxicity of an ineffective treatment that it would be continued uselessly, (ii) and to allow a early changing to an alternative chemotherapy regimen.
The purpose of this study is to determine safety and feasibility of adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) with mitomycin and cisplatin in patients with locally advanced gastric cancer undergoing standard surgical resection. Patients will be treated with HIPEC using a single dose of mitomycin 15mg/m2 and cisplatin 50mg/m2 at 41-42 C for 90 minutes, during the definitive surgical resection for gastric cancer. HIPEC will be performed after resection but before anastomosis.
This is an Open Label, Prospective, Multicentre, Non-interventional Study of Apatinib for Chemotherapy-Refractory Advanced Metastatic Gastric Cancer, the investigators opted to give patients for apatinib 850 mg once daily, 28 days for a cycle. To evaluate the safety and efficacy of apatinib for Advanced Metastatic Gastric Cancer in the real world.
