Despite the declining incidence, gastric cancer (GC) remains the second leading cause of cancer death worldwide. In France, it is the second digestive cancer with 7,000 new cases per year. It is now well demonstrated that patients with H. pylori infection, atrophic gastritis and intestinal metaplasia, have a high risk of developing GC. It is therefore important to detect these pre-neoplastic lesions at an early stage to improve patients prognosis. Thus, the aim of this p...
This will be a pilot study investigating the feasibility of using pressurized irrigation of the stomach mucosa to obtain gastric aspirate cell samples for analysis and identification of premalignant lesions of the stomach.
Aim: To investigate the glucagonostatic effect of glucagon-like peptide-1 (GLP-1) independent of the gastric emptying rate.
Without high diagnostic efficacy of endoscopic forceps biopsy (EFB) and with low diagnostic efficacy of narrow band imaging (NBI) in novice endoscopists and endoscopists of community hospitals in China, it is urgent to improve diagnostic efficacy for gastric cancerous lesions.The investigators will conduct a study to develop and validate a diagnostic model based on NBI for early gastric cancerous lesions under endoscopic observation.
Gastric GISTs are rare neoplasms that require excision for cure. Although the feasibility of laparoscopic resection of gastric GIST less than 2cms has been established, the feasibility, safety and long-term efficacy of these techniques for larger lesions are unclear. Investigators hypothesized that laparoscopic resection of gastric GISTs even for larger lesions is feasible & results in low perioperative morbidity and an effective long-term control of the disease.
To explore the effects of bile reflux on gastric cancer and its precancerous lesions, so as to better prevent the occurrence and development of gastric cancer.
A clinical study of the efficacy of oral alpha-difluoromethylornithine (eflornithine or DFMO) in male and female subjects ages 30-60 with gastric premalignant lesions in two high risk regions of Latin America.
The purpose of study is to examine whether raised blood glucose enhances lipid particle production independent of effects on gastric emptying and pancreatic/ gastrointestinal hormone production.
Background: Long-term success of organ transplantation is limited by the inexorable loss of graft function due to rejection. Prevalent dogma defends that allograft rejection is exclusively mediated by the adaptive immune system: T cells are responsible for cellular rejections and B cells producing donor specific antibodies (DSA) are responsible for humoral rejection. Recently, we demonstrated that innate NK cells could be implicated in the generation of chronic vascular ...
This trial is to evaluate the safety and effectiveness of activated and expanded in vitro autologous NK cells following trastuzumab treatment for patients Human Epidermal Receptor-2 overexpressing advanced gastric cancer.
Endothelin-1 (ET-1) is a powerful vasoconstricting peptide produced predominantly by vascular endothelial cells, that exerts its effect through the interaction with specific receptors, ETA and ETB, on the underlying smooth muscle cells. Previous studies in normal subjects have demonstrated an increase in forearm blood flow after ET-1 antagonism, suggesting a physiologic role of ET-1 in the regulation of basal vascular tone. However, whether ET-1-mediated tone is increased in ...
Helicobacter pylori (H. pylori) is associated with gastric cancer in epidemiological studies.Gastric atrophy and intestinal metaplasia caused by H. pylori are considered as precancerous lesions, but whether H. pylori eradication improves these lesions is controversial.The primary objective of this study is to evaluate whether Helicobacter pylori eradication improves glandular atrophy and intestinal metaplasia which are known to be precancerous condition in patients undergoing s...
Research purpose To elucidate the effect mechanism and clinical effective of weifuchun in the prevention and treatment of chronic atrophic gastritis and precancerous lesions of gastric cancer. From genes related to cell differentiation, proliferation, apoptosis, tumor invasion and metastasis, genes related to immune inflammation and immune escape and other possible aspects to elucidate the effective and mechanism of weifuchun's treatment on chronic atrophic gastritis, reversing...
Objectives 1. To determine the increase in VZV-specific cell-mediated immune response from pre-zoster vaccination to 3 weeks post-vaccination in nursing home residents after 4 months of high dose vs. standard dose vitamin D3 supplementation. 2. In the same participants as Aim 1, to measure the association between pre-zoster vaccination 25-hydroxyvitamin D [25(OH)D] levels and the increase in VZV-specific cell-mediated immune response from pre- va...
Gastric cancer is one of the most common malignancies in China. Early detection is critical for gastric cancer management. However, the diagnosis rate of patients with early gastric cancer is still low. Therefore, we design this study to access whether pre-endoscopic screening risk assessment of genetic and environmental risk factors could improve early gastric cancer diagnosis rate.
Gastric cancer is the third most common cause of cancer-related death worldwide (1). Upper endoscopy is necessary to detect neoplastic macroscopic features at an early stage, but subtle abnormalities in the gastric mucosa are often missed or misdiagnosed (1). Helicobacter pylori (Hp) is involved in the pathogenesis of gastric diseases, such as, peptic ulcers, gastric lymphoma, and gastric cancer. Therefore, the necessity to recognize malignant gastric lesions at an early stage ...
This clinical trial evaluated the gastroprotection obtained by the use of rebamipide 300 mg (2x daily) and rabeprazole 20 mg/day (1x daily) associated or not in the prevention of gastric lesions induced by naproxen 1100 mg/day) for 7 days to healthy volunteers of both sexes. This trial also assessed drugs safety and tolerability, the prostaglandin levels (PGE2) in biopsy specimens before and after treatment of each group and the histopathological changes induced by the treatmen...
Gastric cancer is the second leading cause of cancer deaths in the World. In China, gastric cancer exceeds all other cancer mortality except lung cancer. Helicobacter pylori infection is an important cause of gastric cancer. We have previously started a randomized placebo-controlled chemoprevention trial in Changle in 1994 to address the issue of whether eradication of H. pylori alone is able to prevent or reduce the risk of gastric cancer. The project involved 1600 subjects an...
Gastric cancer is the second most common neoplasm in the world. Early diagnosis and surgical resection improve the survival and the chance of cure. Unfortunately, majority of cases are diagnosed at advanced stage, with only 20% of the patients presenting with localized disease. The five-year survival for gastric cancer of all stages remains at a dismal 8%. Chemotherapy has been used for advanced gastric cancer but with unsatisfactory results. Therefore, new approaches are ...

Methods: This study designs a novel therapy using PIK-HER2 cells. 40 Her2 positive patients with liver metastasis from gastric cancer will be enrolled. They are randomly divided into dendritic cell-precision multiple antigen T cells (DC-PMAT) group and PIK-HER2 cells group. B...
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.
Treatment by association of complete surgical excision of the lesions and intraperitoneal immunotherapy using Catumaxomab for patients with gastric peritoneal carcinomatosis
We are undertaking a study of patients with gastric or pancreatic cancer. A common place for cancer to return after surgery for gastric or pancreatic cancer is the inside lining of the abdomen, called "peritoneal metastasis". At the time of surgery, washing the abdomen with a mild salt solution may reveal free cancer cells in the abdomen which could develop into peritoneal metastasis. Recently, surgeons here at Memorial Sloan-Kettering have found that patients who have these ce...
The purpose of this study was to compare the outcomes of medical augmented reality glasses and general monitors when distinguishing mucosal lesions from submucosal lesions in endoscopic diagnosis for early gastric cancer.
Videoendoscopy is the standard tool for examination of gastrointestinal tract. However, precancerous lesions and early gastric cancer can be easily missed by routine videoendoscopy. Autofluorescence Imaging (AFI) and Narrow band imaging (NBI) are 2 new imaging systems used in endoscopy which are recently developed. AFI based on the presence of natural tissue fluorescence on the gastrointestinal tract. By computation of the difference in the reflecting images, the system can re...
