Next-Generation Sequencing to Evaluate Transcriptomic Changes Associated With H. Pylori Infection and Gastric Cancer Carcinogenesis
Weill Medical College of Cornell University
Summary
This is a research study for patients who currently have or previously had an H. pylori infection or who have gastric or esophageal cancer and who plan to undergo an endoscopy as part of their care. The purpose of this study is to find out how and why H. pylori infections can cause progression to gastric cancer and if it's possible for intervention prior to this progression.
Description
H. pylori infection is a prevalent environmental cause of gastric cancer. The molecular mechanisms of carcinogenesis due to H. pylori remain unexplained and consequences of infection are variable and unpredictable. The aim of this research is to examine the RNA transcriptome of gastric cancer mucosa (gastric mucosa is the mucus membrane of the stomach), in patients with H. pylori infection and examine the spectrum of disease associated with infection. We will also examine bacterial content of samples to pinpoint the specific H. pylori strain(s) and the stomach microbial profile to correlate wi…

Inclusion Criteria: * Patient must be 18 years or older * Patient must have active or prior H. pylori infection, or have been treated for H.pylori infection in the past, as assessed by ELISA (not applicable for the subset of patient controls) or have gastric or esophageal cancer or have Barrett's Esophagus * Patients must be eligible for and are planning to undergo a routine upper endoscopy and tissue biopsy * Patients must sign informed consent Exclusion Criteria: * Prior history of upper GI bleed (within 3 months) * Bleeding disorder or coagulopathy * Recent stroke or myocardial infarctio…
Interventions
- ProcedureEndoscopy tissue collection
The investigational part of this study is the requirement for an additional biopsy from a site that is already being biopsied at the time of a routine endoscopy. Any patients who develop bleeding following their routine clinical biopsies will not undergo any additional research biopsies.
