Active clinical trials for "Stomach Neoplasms"

The goal of the study is to understand whether blood levels of hormones produced or metabolized in the stomach reflect the health of the stomach lining. Specifically the study will determine whether the concentration of ghrelin, gastrin, pepsinogens and vitamin B12 reflect the condition of the stomach lining. Hormone concentrations for people with normal/mild gastritis will be compared to people with long-term inflammation of the stomach (chronic atrophic gastritis), and people with pre-cancerous cellular changes (intestinal metaplasia).

Neoadjuvant chemotherapy has become the mainstream recommended treatment for advanced gastric cancer. However, due to the heterogeneity of gastric cancer, part of some patients fail to benefit from the treatment. This project aims to compare the clinical efficacy of individualized neoadjuvant therapy based on patient-derived organoid drug sensitivity assay and traditional regimen, exploring the advantages and disadvantages of these two treatments. And access the safety and clinical value of the personalized neoadjuvant therapy based on patient-derived organoid drug sensitivity assay in advanced gastric cancer.

This CLASS02-01 trial is a prospective, multicenter trial for laparoscopic total gastrectomy (LTG) and open total gastrectomy (OTG) in patients with clinical stage I (T1N0M0、T1N1M0、T2N0M0) gastric cancer. The primary purpose of this study is to evaluate the early operative morbidity and mortality and determine the safety of LTG compared with OTG for clinical stage I gastric adenocarcinoma. The second purpose is to evaluate the recovery course and compare the postoperative hospital stay of the patients enrolled in this study.

The investigators compared the perioperative, oncological, functional and immunological outcomes of endoscopic submucosal dissection against laparoscopic assisted gastrectomy for treatment of early gastric cancer. With virtually no abdominal incisions and minimal pain induced, endoscopic submucosal dissection is expected to be less invasive when compared to laparoscopic assisted gastrectomy for treatment of early gastric cancer. This study will show that endoscopic submucosal dissection is associated with a significantly better perioperative recovery and less immunological disturbance. Moreover, it will also induce a better long term outcomes as the stomach can be preserved, hence the digestive function is maintained to prevent long term functional morbidities of the gastrointestinal tract. This study will be the unique first study in the literature to show that intramucosal early gastric cancer can be adequately treated by endoscopic submucosal dissection with better perioperative, functional and quality of life outcomes when compared to laparoscopic assisted gastrectomy.

In this randomized controlled trial, we investigate the effect of 10-day bismuth quadruple therapy in comparison with that of 7-day PPI-based standard triple as 1st line treatment for H. pylori.

This is a Phase 1b study evaluating a combination of PEGPH20 and pembrolizumab in hyaluronan-high (HA-high) participants with relapsed/refractory non-small cell lung cancer (NSCLC) and HA-high participants with relapsed/refractory gastric adenocarcinoma (GAC).

The efficacy of HIPEC in prevention of local recurrence, distant metastasis or peritoneal metastasis in locally advanced gastric cancer is not definite. The hypothesis of the trial is that radical gastrectomy plus HIPEC is superior to only radical gastrectomy in terms of overall survival.

RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. PURPOSE: This phase II trial is studying how well everolimus works in treating patients with previously treated unresectable or metastatic esophageal cancer or stomach cancer.

This randomized phase II trial studies how well docetaxel, oxaliplatin, capecitabine, fluorouracil, and radiation therapy works compared with fluorouracil when given together with oxaliplatin and radiation therapy in treating patients with cancer of the esophagus or gastroesophageal junction that has spread from where it started to nearby tissue or lymph nodes. Drugs used in chemotherapy, such as docetaxel, oxaliplatin, capecitabine, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving more than one drug (combination chemotherapy) together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

Apatinib is a tyrosin-inhibitor agent targeting at vascular endothelial growth factor receptor (VEGFR), and it's anti-angiogenesis effect has been viewed in preclinical tests. The investigators' phase I study has shown that the drug's toxicity is manageable and the maximum tolerable daily dose is 850 mg. The purpose of this study is to determine whether apatinib can improve progression free survival compared with placebo in patients with metastatic gastric carcinoma who failed two lines of chemotherapy.
