Abstract

Background/Aim: S-1, cisplatin, and docetaxel (DCS) constitute an effective regimen for gastric cancer. We conducted a retrospective cohort study of systemic DCS and a prospective phase I trial of intraperitoneal DCS in the preoperative setting for marginally resectable gastric cancer. Patients and Methods: Under the systemic regimen, patients received cisplatin (60 mg/m2) plus docetaxel (40 mg/m2) intravenously on day 1 and S-1 (80 mg/m2) on days 1-14, of a 28-day cycle. With the intraperitoneal regimen, the schedule for S-1 and cisplatin was the same. Dose escalation for docetaxel started at 30 mg/m2 (level 1). Results: Between August 2010 and July 2013, 26 consecutive patients were treated with the systemic regimen. Grade 3-4 neutropenia occurred in 81% but the toxicity profile was very tolerable. The response rate based on the Response Evaluation Criteria in Solid Tumors (RECIST) was 89%. Between April 2012 and April 2014, 5 patients with linitis plastica, large ulcero-invasive type tumors, positive washing cytology or peritoneal metastasis were enrolled in the phase I trial of the intraper itoneal regimen. Grade 3-4 elevations in aspartate/alanine aminotransferase (AST/ALT) occurred in the first 2 patients. The next 3 patients, who received docetaxel (20 mg/m2) on days 1 and 15 (level 0), had no dose-limiting toxicity. Four patients, including 3 with peritoneal metastasis and/or positive cytology before treatment, underwent R0 resection after intraperitoneal chemotherapy. Conclusion: Our studies revealed the efficacy of the systemic regimen and the safety of the intraperitoneal regimen. Further investigation of these two types of preoperative DCS chemotherapy is warranted.
