Neutropenic fever and neoadjuvant intraperitoneal and systemic chemotherapy (DCF-like) in gastric cancer with peritoneal dissemination.

144 Background: Neoadjuvant intraperitoneal and systemic chemotherapy (NIPS) is a new treatment modality in gastric cancer with peritoneal seeding. Several phase I-II clinical trials with NIPS and cytoreductive surgery have shown an increase in overall survival in Japanese patients (pts) with acceptable toxicity. We report the toxicity related to neutropenia and granulocyte colony stimulating factor (G-CSF) use of the first experience in Spain with NIPS (DCF-like) in gastric cancer with peritoneal carcinomatosis. Methods: Ten consecutive pts have been enrolled in this protocol in a compassionate use program in our center from 2009 to 2011. Chemotherapy (DCF-like) was delivered through an implantable peritoneal catheter. Primary prophylaxis with GCS-F was not used as described in the phase II studies, except in one pt. Clinical characteristics (Table). Results: The incidence of grade 3–4 neutropenia was 70% and any grade neutropenia 80%. Febrile neutropenia was described in 50% of the pts. All pts received...
