AIM: To conduct a phase II study of single intraperitoneal (i.p.) administration of paclitaxel followed by paclitaxel, cisplatin, and S-1 (PCS) chemotherapy for patients with gastric cancer with peritoneal metastasis (PM). PATIENTS AND METHODS: Staging laparotomy was performed to confirm PM. Initially, patients received i.p. paclitaxel. Beginning 7 days later, PCS was given every 3 weeks followed by second-look laparoscopy. Primary and secondary endpoints were the overall survival (OS) rate, and response rate and patient safety, respectively. RESULTS: Seventeen patients were enrolled. The overall response rate was 70.5% (12/17). Grade 3/4 toxic effects included neutropenia and leukopenia. After chemotherapy, PM disappearance was confirmed in 11 patients. Gastrectomy was eventually performed in 11 patients. The 1-year OS rate was 82.4% and the median survival time was 23.9 months considering the overall cohort. CONCLUSION: Combination chemotherapy with i.p. paclitaxel and PCS is well tolerated and effective in patients with gastric cancer with PM. Copyright
