Active clinical trials for "Stomach Neoplasms"

A Japanese study showed that the additional use of an "Extensive Intraperitoneal Lavage" (EIPL), i.e. an extensive washing of the abdominal cavity with water, during surgery for gastric cancer can lead to a significant increase in survival. However, the study was confined to patients in whom upon commencing surgery, free peritoneal tumor cells were detected, which is only a small fraction of patients. The primary objective of our study is to assess in all patients undergoing removal of the stomach and adjacent lymph nodes for stomach cancer, if EIPL can eliminate free peritoneal tumor cells which have been present at the beginning of the surgery or after the stomach and lymph node removal. Secondary objectives are to assess how often free peritoneal tumor cells occur in patients with stomach cancer, how often surgical resection itself leads to a release of tumor cells, the safety of the EIPL procedure, and disease-free and overall survival of patients undergoing EIPL. Based on the outcome of this japanese study we want to test with special laboratory methods why this lavage leads to a better outcome. Specifically, the trial will test the hypotheses that a) lymph node dissection causes a release of tumor cells in the abdominal cavity, and b) EIPL eliminates free peritoneal tumor cells.

RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy together with radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. PURPOSE: This phase II trial is studying how well giving oxaliplatin and capecitabine together with radiation therapy works in treating patients with stomach cancer that can be removed by surgery.

RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. PURPOSE: Randomized phase II trial to compare the effectiveness of two different vaccines in treating patients who have cancer of the gastrointestinal tract.

RATIONALE: Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bortezomib together with fluorouracil and leucovorin may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving bortezomib together with fluorouracil and leucovorin works in treating patients with metastatic or unresectable stomach cancer.

The purpose of this study is to find out whether treatment with trastuzumab combined with pembrolizumab will improve the clearance of tumor DNA from participants' bodies after surgery.

Randomized Controlled Trial to Prevent Peritoneal Seeding in Gastric Cancer

The choice of surgical strategy for patients with proximal gastric cancer is controversial mainly because proximal gastrectomy is infamous for high rates of reflux symptoms and anastomotic stricture. but there are no prospective randomized trials until now. The primary end point of this study is whether the rate of reflux esophagitis is different or not between LAPG and LATG. Through this study, we

The aim of this study is to demonstrate the influence of peri-operative nutrition on the post-operative complications, preservation of lean body mass and length of stay after gastrectomy or oesophagectomy.

There are still some unsolved questions regarding population-based screening program for H. pylori infection to prevent gastric cancer, such as how to perform the optimal screening strategies. A prospective, randomized trial will be conducted to compare the acceptability, compliance (/adherence), and accuracy of diagnostic tests in a population-based H. pylori screening and gastric cancer prevention program. The investigators will recruit 10,000 adults with age of ≥20 years who have not received H. pylori screening or treatment. Eligible patients will be randomly 1:1:1:1 allocated to four groups with different combination tests.

The purpose of this study is to assess the dosimetric properties of the positron emission tomography (PET) imaging probe 68Ga labeled HER2 Affibody analogues and preliminarily evaluate its diagnosis value in patients with breast or gastric tumors.
