BACKGROUND: Efficacy and safety of irinotecan and cisplatin administration every 2 weeks (biweekly regimen) or 4 weeks (4-weekly regimen) in patients with pretreated unresectable or recurrent gastric cancer was retrospectively evaluated. METHODS: Study patients comprised two cohorts: cohort 1, consisting of 31 patients received chemotherapy on a 4-weekly regimen; and cohort 2, consisting of 32 patients received chemotherapy on a biweekly regimen. In cohort 1, patients received irinotecan (70 mg/m(2)) on days 1 and 15 and cisplatin (80 mg/m(2)) on day 1 every 4 weeks; in cohort 2, patients received irinotecan (60 mg/m(2)) on day 1 and cisplatin (30 mg/m(2)) on day 1 every 2 weeks. RESULTS: Response rates were for cohorts 1 and 2 were 26% (7/27) and 28% (7/25) in patients with measurable lesions, median progression-free survivals were 3.5 and 4.3 months, and median survival times after irinotecan and cisplatin initiation were 9.5 and 10.1 months, respectively. The incidence of grades 3 and 4 hematological toxicities in cohorts 1 and 2 were 74% and 44% for leukopenia, 81% and 53% for neutropenia, and 45% and 28% for anemia, respectively. Incidences of grades 3 and 4 nonhematological toxicities were 23% and 12% for nausea, 23% and 9% for vomiting, 19% and 12% for anorexia, and 6% and 6% for febrile neutropenia, respectively. CONCLUSION: Irinotecan plus cisplatin chemotherapy administered on a biweekly regimen was comparable in efficacy to a 4-weekly regimen and might be more feasible than the 4-weekly regimen.
