Investigating how H. pylori infections may lead to gastric cancer

Next-Generation Sequencing to Evaluate Transcriptomic Changes Associated With H. Pylori Infection and Gastric Cancer Carcinogenesis

Observational Weill Medical College of Cornell University · NCT02164409

This study is trying to understand how H. pylori infections might lead to stomach cancer by looking at tissue samples from patients who have had these infections or have stomach or esophageal cancer.

What this trial studies

This research focuses on patients with current or past H. pylori infections, as well as those with gastric or esophageal cancer, who are scheduled for an endoscopy. The study aims to explore the molecular mechanisms by which H. pylori may contribute to gastric cancer development by analyzing RNA transcriptomes and bacterial content from gastric mucosa samples. Up to four additional biopsies will be collected for next-generation sequencing and bioinformatics analysis to identify genetic factors influencing cancer progression. The research is conducted at Weill Cornell Medical College under the supervision of experienced researchers.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with active or prior H. pylori infections or those diagnosed with gastric or esophageal cancer who are undergoing endoscopy.

Not a fit: Patients with recent upper GI bleeding, bleeding disorders, or recent strokes or heart attacks may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into the genetic factors that influence the progression of gastric cancer, potentially leading to preventive interventions.

How similar studies have performed: While the investigation of H. pylori's role in gastric cancer is established, the specific molecular analysis approach in this study may provide novel insights, making it a potentially unique contribution to the field.
