About this trial
This is a phase II study conducted in three hospitals in the Netherlands (Erasmus MC in Rotterdam, Catharina Hospital in Eindhoven, and the Netherlands Cancer Institute in Amsterdam). A total of 55 patients will take part. The aim is to test whether a new combination treatment is feasible for patients with gastric peritoneal metastases (PM). The treatment includes chemotherapy (intraperitoneal irinotecan and standard systemic therapy such as CAPOX or FOLFOX), and may also include nivolumab or trastuzumab, depending on biomarker results.
