Core Tip

Core tip: We present a retrospective review of the clinical course and treatment outcomes of patients with gastric peritoneal carcinomatosis. It carries a poor prognosis with a clinical course fraught with disease-related complications which disrupts planned systemic palliative chemotherapy in the majority of patients. Such disruptions attenuate the benefits of systemic chemotherapy and decrease overall survival. Patients with isolated peritoneal disease may as such benefit from investigational loco-regional therapies pending further studies and validation.
