Magnetic dye trial aims to spot hidden stomach cancer spread
NCT ID NCT05038098
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This early-stage study tests whether a magnetic tracer and a fluorescent dye can safely help doctors find lymph nodes where stomach cancer may have spread. About 20 adults with early stomach cancer will receive the injection before surgery. The goal is to see if this method is safe and could improve detection of cancer spread.
