Filter by:Currently no ideal preventive modalities are available for reducing gastric-cancer caused mortality in organized population-based application. The primary objective of the study is to determine if H.pylori screening followed by eradication of positive subjects and endoscopic follow-up of those with serological evidence of atrophic gastritis reduces mortality from gastric cancer in middle-aged people in high-risk areas. The GISTAR study is a multicenter randomized study of H.pylori eradication and pepsinogen testing for prevention of gastric cancer mortality. Altogether 30.000 individuals aged 40-64 years will be enrolled, providing 90% study power to detect at least 35% reduction in gastric cancer mortality at 15 years of follow-up. Participants will be randomly allocated to one of two groups. In the active investigation/management group those positive for H.pylori will be offered eradication therapy and individuals with decreased pepsinogen I/II ratio will be invited for endoscopy. The control group will receive standard health care. The primary endpoint for this trial will be the mortality difference from gastric cancer between the two groups at 15 years or when enough cases accumulate to demonstrate a statistical difference. The study is expected to provide valuable information on the utility for reduction in gastric cancer mortality of: 1) H.pylori eradication in adults on a population-basis, including subjects who may already have pre-malignant lesions; and 2) pepsinogen testing in screening settings. A pilot study of 3,455 individuals prior to the main trial was conducted from October 2013 to December 2016.
Investigators have a plan to conduct nested case-control study to investigate the association between serum cholesterol levels including TC, HDL-C, LDL-C, triglyceride (TG), apolipoproteins and gastric neoplasm. In addition, further analyses were performed to evaluate the possible role of the serum cholesterol as a predictor for the differentiation and prognosis of gastric neoplasm.
Besides major ESD-related complications, minor adverse events after ESD are also commonly noticed. Pain is one of minor ESD-related complications. . The causes of pain associated with ESD or gastric polypectomy are thought to be associated with transmural burn or transmural air leak. How control localized pain for patients who suffered from pain after ESD is appearing as new medical interests. There are few studies about management strategy for pain after ESD. Glucocorticoids are used to reduce inflammation and tissue damage in various clinical settings including inflammatory disease, rheumatic disease, and so on. The efficacy of glucocorticoids for reducing pain after surgery has recently been investigated. Glucocorticoids are thought to locally inhibit collagen deposition and fibrosis and finally reduce scar-tissue formation. Especially systemic steroids are easy to achieve a continuous effect through stable serum concentrations. If pain was partially associated with acute inflammation, we assumed intravenous dexamethasone could be helpful to relieve pain after ESD based on previous studies. we aimed to assess the efficacy of single dose postoperative intravenous dexamethasone for pain relief after ESD.
This study will determine the safety and efficacy of expanded activated autologous NK cells administered after Trastuzumab in patients with HER2-positive breast or gastric cancer. It will also provide valuable insights of the role of NK cell infusions in adult solid tumors.
For gastric patients of Karnofsky scores between 60-80 scores, mFolfox6 is an option for chemotherapy. Neutropenia and oxaliplatin-induced neurotoxicity are the most common adverse effects which even result in discontinue of chemotherapy, especially for patients suffered from heavily acute neurotoxicity. Monosialotetrahexosylganglioside is a component of membrane of nerve cells. Previous phase II clinical trial showed, it can reduce oxaliplatin-induced neurotoxicity(OIN). But it did not certificated by phase III trial. A phase III trial is needed to investigate the effect and safety of monosialotetrahexosylganglioside Sodium Injection for prevention OIN at gastric cancer.
To investigate the feasibility, safety and tolerability of Preoperative Chemoradiation in Patients With Localized Gastric Cancer. Primary endpoint: R0 resection rate. Secondary endpoint: resection rate, pathological complete regression (pCR), effectiveness and safety of regime, disease free survival(DFS) and overall survival(OS).
Second-line chemotherapy represents an option in gastric cancer, especially for patients with adequate performance status. Two randomized phase III trials comparing 2nd-line docetaxel with best-supportive care have reported a benefit in favor of chemotherapy. Capecitabine is a fluoropyrimidine carbamate, which has a broader spectrum of antitumor activity than other fluoropyrimidines. In gastric cancer xenografts. metronomic capecitabine inhibited angiogenesis, growth of gastric cancer and improved survival with less toxicity. Given its potential low toxicity, the combination of docetaxel and metronomic capecitabine needs to be evaluated to assess efficacy and tolerability in patients with advanced gastric cancer previously treated with a fluoropyrimidine-based and platinum-based chemotherapy.
Gastroenterologists often follow up second look endoscopy after endoscopic submucosal dissection(ESD) of gastric neoplasms because they want to prevent bleeding of procedure sites. But Goto suggested in his retrospective analysis that a second-look endoscopy after endoscopic submucosal dissection for gastric epithelial neoplasm may be unnecessary. So, the investigators try to identify the hypothesis prospectively in this study.
Elderly patients are generally underrepresented in the study populations of combination chemotherapy trials. In gastric cancer patients, oxaliplatin has shown a more favorable toxicity profile than cisplatin. A combination chemotherapy of 5-fluorouracil (5-FU) with oxaliplatin, mainly FOLFOX regimens, has been investigated in numerous phase II studies, using different doses and schedules, and has shown considerable antitumor activity. Insofar as toxicity is concerned, significant toxicities, including myelo-suppression and peripheral neuropathy, are a major issue for elderly patients. A modified FOLFOX regimen by omitting the administration of bolus 5-fluorouracil have shown a good profile of activity and tolerability in the elder population. This study evaluates the efficacy and safety of a modified FOLFOX (m FOLFOX) regimen for up to 8 cycles followed by capecitabine maintenance in elderly patients with metastatic gastric cancer and presenting associated disease(s)
The purpose of this study is to find out whether the nutritional status of patients undergoing Functional Jejunal Interposition is better than those with Roux-en-Y After Total Gastrectomy for Gastric Cancer. To find a better reconstruction for patients who received total gastrectomy.
