Chemotherapy delivered straight to the belly: new hope for stomach cancer patients
NCT ID NCT07133490
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new treatment for stomach cancer that has spread to the lining of the belly (peritoneal metastases). About 55 patients will receive chemotherapy directly into the abdomen along with standard intravenous chemotherapy, and possibly immunotherapy or targeted therapy based on their tumor markers. The goal is to see if this combination is feasible and can help control the disease.
