Active clinical trials for "Stomach Neoplasms"

Subepithelial lesions (SEL) are incidentally observed in the stomach of about 0.3% of middle-aged men and women; half of these are neoplastic. The incidence of subepithelial tumors (SET) of gastrointestinal (GI) origin has risen twofold to fivefold within the past 30 years.The etiology of most SMTs cannot easily be determined by endoscopy. So, we aim to estimate the prevalence and types of sub-epithelial lesions among patients undergoing EGDs in Egypt.

A prospective study of the results of laparoscopic approach of gastric carcinoma in western patients is designed. The working hypothesis proposes obtaining similar results to those obtained in the series reported by eastern hospitals (Japan and Korea) and, at least, equivalent to those recorded in conventional surgery.

In this study, the investigators aimed to identify independent prognostic factors for early postoperative complications and survival in elderly patients (aged ≥65 years) with gastric cancer.

Background. Gastric cancer surgery is associated with high risk for postoperative morbidity and mortality. Anastomotic leak (AL) is one of the worst complications associated with relevant short and long-term sequelae. Procalcitonin (PCT) is a biomarker used to monitor bacterial infections and guide antibiotic therapy and has been shown to have better predictive value of AL after colorectal surgery than C-reactive protein (CRP) and white blood cell count (WBC). Purpose. Investigators designed a monocentric pilot study to test if PCT might be a sensitive and reliable marker of AL after gastric surgery

The aim of this study was to investigate the expression of ZEB1 in CTCs for gastric cancer, its correlation with the clinicopathology of gastric cancer, and the role of ZEB1 in invasion and metastasis in gastric cancer.

Considering the development of gastric cancer surgery using da Vinci Robotic Surgical System, the development of educational program needs to be achieved in Korea and this institute. Moreover, because of the large number of gastrectomy including robotic surgery for gastric cancer treatment, the investigators can provide high quality of educational program using da Vinci System. Therefore, the investigators wanted to create an innovative real-time training module, which can provide an intraoperative step-by-step guide to robotic surgical procedures. This technological project was named as Advanced Robotic Multi-display Educational System (ARMES).

Find A Cure Panel is looking for people with Stage 4 stomach/gastric cancer or the caregivers of people with Stage 4 stomach/gastric cancer to participate in anonymous and qualitative research that will take an estimated 60 minutes of your time. This is opinion based, experiential research and is NOT a drug trial. Note that Stage IV is also known as "advance disease" or metastatic stomach/gastric cancer. If you are interested in participating, please email FACP at: info@findacurepanel.com

The objective of this study is to investigate the proportion of HER2 overexpression in gastric cancer patients group, to evaluate the relation of HER2 overexpression with prognosis, and to analyze the proportion of herceptin applied to patients in clinical field. Furthermore, the investigators are going to reevaluate the clinical benefit of Herceptin for survival prolongation compared to chemotherapy only.

Background: Atrophic gastritis (AG) is the single most important precursor condition for gastric cancer (GC) known so far. H. pylori infection is the most important causative agent of gastritis, and subsequent AG. The GastroPanel test (Biohit HealthCare, Helsinki, Finland), a blood test evaluating the four biomarkers specific for the gastric mucosa pepsinogen I (P-PGI), pepsinogen II (P-PGII), gastrin-17 (P-G-17) and H. pylori antibody (P-HpAb), is the first non-invasive diagnostic tool providing possibilities for detecting the patients at risk for GC and peptic ulcer as well as malabsorption of vitamin B12, iron, magnesium, calcium and some drugs. A well designed clinical study is warranted to fully assess the performance of GastroPanel examination in detecting the gastric lesions which can lead to GC. The investigators aim to perform a clinical study in an adult population in United Kingdom in order to determine the diagnostic accuracy of the GastroPanel test in evaluating AG and other specific gastric conditions associated with an increased risk for GC. Methods: Two hundred and fifty patients (45 years and older, both genders) will be enrolled among the patients with dyspepsia referred for gastroscopy at Homerton University Hospital (London, United Kingdom). During the same visit, all patients are subjected to gastroscopy examination, with directed biopsies from the antrum and corpus, following the protocol of the operative link on gastritis assessment (OLGA) classification for chronic gastritis and Sydney Classification. Biopsies are examined at the Pathology laboratory of Homerton University Hospital and interpreted using the OLGA staging system as well as the Sydney system for classification of gastritis. Specific aims: The principal goal of this clinical trial is to establish the performance of the GastroPanel examination in detecting AG and other specific gastric conditions associated with an increased risk for GC. In particular, the investigators will evaluate AG in the antrum, AG in the corpus, AG in both antrum and corpus (=atrophic pangastritis), biopsy-confirmed dysplasia (intestinal metaplasia) of the gastric mucosa. For all these conditions, the investigators will calculate the diagnostic accuracy of the GastroPanel test.

The MET oncogene encodes the receptor tyrosine kinase (RTK) for hepatocyte growth factor (HGF) and controls genetic programs leading to cell growth, invasion and protec¬tion from apoptosis. Although the definitive role of MET oncogene is yet to be determined in carcinogenesis of gastric cancer, overexpression and amplification of c-Met has been demonstrated in gastric cancer cell lines. In addition, approximately 10-20% of gastric cancer tissues and up to 40% of the scirrhous histological subtype were shown to harbor increased MET gene copy numbers. Importantly, PHA-665,752, a selective c-Met kinase inhibitor showed significant reduction of established tumor mass in mouse xenografts with GTL16, a gastric cancer cell line with >10-fold MET amplification. Another pivotal study showed that gastric cancer cells with MET amplification were extremely sensitive to PHA-665,752 and implicated a potential role of c-Met protein in developing theranostics in gastric cancer. More and more data indicated that c-Met was an important prognostic factor in gastric cancer. Gastric cancer is a heterogeneous disease. Does the expression and amplification of c-Met in the primary lesion differ from the metastatic disease? Does the expression and amplification of c-Met in the early disease differ from advanced disease? Till now there is no related report. Purposes: Compare the expression and amplification of c-Met between primary lesion and metastatic lesion together with clinical characteristic, to explore the relationship of c-Met expression and metastatic pattern Compare the expression and amplification of c-Met between early stage and metastatic stage, and to explore the role of c-MET in the development of carcinoma
