Peritoneal metastasis is the most common pattern of synchronous and metachronous dissemination in gastric cancer (GC) and is associated with a poor prognosis. Even though systemic chemotherapy is the standard of care, the optimal therapeutic approach to peritoneal disease in this setting is yet to be defined. We present a case of a 26-year-old female diagnosed with locally advanced GC who developed peritoneal carcinomatosis (PC). The patient underwent cytoreductive surgery (CRS) along with hyperthermic intraperitoneal chemotherapy (HIPEC) with complete remission. She remained disease-free after six years, presenting with peritoneal recurrence 70 months after the procedure. This report describes a rare case of long-term survival following a controversial therapeutic approach.
