C-Met Inhibitor AMG 337, Oxaliplatin, Leucovorin Calcium, and Fluorouracil in Treating Patients...

Adenocarcinoma of the EsophagusAdenocarcinoma of the Gastroesophageal Junction12 more

This partially randomized phase I/II trial studies the side effects and best dose of c-Met inhibitor AMG 337 when given together with oxaliplatin, leucovorin calcium, and fluorouracil and to see how well they work in treating patients with stomach or esophageal cancer that has spread to other places in the body and usually cannot be cured or controlled with treatment. C-Met inhibitor AMG 337 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as, oxaliplatin, leucovorin calcium, 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 spreading. Giving c-Met inhibitor AMG 337 with oxaliplatin, leucovorin calcium, and fluorouracil may kill more tumor cells.

Pain After Endoscopic Submucosal Dissection

Gastric Neoplasm

Endoscopic submucosal dissection (ESD) is widely used for local treatment of gastric neoplasms. Although ESD-related complications such as bleeding and perforation have been reported, data is currently lacking on the development of pain, which is one of the most common adverse events after ESD. Therefore, in the present study, we investigated the incidence and clinicopathologic risk factors of pain after ESD.

Necessity Assessment of ME-NBI Targeted Biopsy Compared With EFB

Early Gastric Cancer

The aim of the present study was to assess whether it was necessary to conduct magnifying endoscopy with narrow band imaging (ME-NBI) targeted biopsy compared with endoscopic forceps biopsy (EFB) from white light endoscopy in diagnosing early gastric cancer (EGC). Meanwhile, the investigators proposed the most cost-effective way to diagnose EGC.

Tumor Markers Study in Gastric Cancer for Cancer Immunotherapy (ONCO-RD 010 CRT)

Stomach Neoplasms

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.

Phenylbutyrate and Valganciclovir in Treating Patients With Relapsed or Refractory Epstein-Barr...

Gastric CancerHead and Neck Cancer2 more

RATIONALE: The Epstein-Barr virus can cause cancer and lymphoproliferative disorders. Valganciclovir is an antiviral drug that acts against the Epstein-Barr virus. Phenylbutyrate may make cells infected with Epstein-Barr virus more sensitive to valganciclovir. Giving phenylbutyrate together with valganciclovir may block the growth of Epstein-Barr virus-infected cells and kill more cancer cells. PURPOSE: This phase II trial is studying how well giving phenylbutyrate together with valganciclovir works in treating patients with relapsed or refractory Epstein-Barr virus-positive cancer.

Combining Tongue and Gastric Cancer Cascade With Artificial Intelligence

Artificial IntelligenceTongue1 more

This study combines artificial intelligence with tongue images, by collating and collecting tongue images and diagnostic and pathological results of gastroscopic diseases, mining and analysing the correlation between tongue images and OLGA, OLGIM stages, Correa sequences and constructing prediction models, to deeply investigate the relationship between tongue images and precancerous diseases, precancerous lesions and gastric cancer.

Gastric In Vivo Study

Gastric Cancer

The overall objective of this pilot study is to determine whether multispectral imaging increases the diagnostic accuracy of the current standard of high-definition white-light endoscopy for the detection of gastric neoplasia (high grade dysplasia or cancer). As part of an NCI-funded RO1, the investigators goal is to develop a multispectral endoscopic platform that can be used to survey a large surface area and, potentially, serve as a "red flag" for microendoscopic imaging of small areas. In prior ex vivo evaluations of surgical and endoscopic specimens, the investigators have identified the optical settings and illumination wavelengths that are complementary to white-light imaging and enhance superficial mucosal and vascular changes associated with neoplasia. Based on this initial testing, vital-dye enhanced fluorescence imaging (VFI) and imaging with High Resolution Microendoscope (HRME) have been identified as modalities that may be complementary to white-light imaging. The goal of this pilot study is to preliminarily determine the accuracy of these modalities during the endoscopic surveillance and detection of gastric neoplasia.

Comparison Study for Bile Reflux and Gastric Stasis in Patients After Distal Gastrectomy

Stomach CancerGastrectomy

The purpose of this study is to evaluate the degree of bile reflux and gastric stasis according the reconstruction methods after distal subtotal gastrectomy for gastric cancer, and to find out the proper method. We collect ninety patients who undergo distal gastrectomy for gastric cancers for this study from 5 institutions and randomly divide into 3 groups according to reconstruction methods: 1) Billroth-II (B-II), 2) Roux en Y gastrojejunostomy (RY-GJ) and 3) uncut Roux en Y gastrojejunostomy (uncut RY-GJ).

Prevalence of Helicobacter Pylori Infection and Gastric Cancer in the West Indies

Stomach NeoplasmsGastric Neoplasms1 more

Estimating the prevalence of Helicobacter Pylori infection in newly diagnosed stomach cancers in the West-Indies will help to understand the epidemiology of this cancer, which is over-incident in the West Indies compared to France. In addition, the constitution of a biobank (tumor tissues, healthy tissues and serum) will allow to set up in a second time etiological studies to identify other risk factors in particular in connection with the exposure to environmental pollutants to adapt the prevention measures.
