Stomach cancer study seeks clues in gene silencing
NCT ID NCT06982768
First seen Jun 27, 2026 · Last updated Jul 24, 2026 · Updated 2 times
Summary
This study looks at how a specific gene change (called hMLH1 hypermethylation) affects stomach cancer. Researchers will study 245 patients who had stomach cancer surgery to find links between lifestyle, genetics, and how the cancer behaves. The goal is to better understand why some stomach cancers resist standard chemotherapy and to develop a tool that predicts which treatments will work best for each patient.
