The incidence of synchronous or metachronous peritoneal metastases (PM) in patients with locally advanced gastric cancer is high, and associated with a poor prognosis. The recommended therapeutic option for these patients is systemic chemotherapy and leads to a median of 7-8 months. However, new approaches like cytoreductive surgery and hyperthermic intraperitoneal chemotherapy might help to improve the median survival in selected patients.
Indications, patient selection and the choice of the chemotherapeutic agent are described in this manuscript, as well as an overview of the most recent literature about this topic.
