Can a simple biopsy replace surgery for gastric cancer testing?
NCT ID NCT04809025
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether a small tissue sample taken during an endoscopy (biopsy) can give the same information about gastric cancer as a larger sample taken during surgery. Researchers will compare results from 510 patients to see if the biopsy is just as accurate for key cancer markers. If it is, patients might avoid more invasive procedures.

What this could lead to
If successful, this could show that a simple biopsy is as reliable as surgery for key gastric cancer tests, potentially reducing the need for invasive procedures.
What could go wrong
This is an observational comparison, not a treatment trial. Results may not apply to all patients or change current practice.
