BACKGROUND: The purpose of this study was to evaluate the toxicity and antitumor effect of cisplatin, irinotecan and etoposide combinations on two schedules, arms A and B, for previously untreated extensive small-cell lung cancer (E-SCLC), and to select the right arm for phase III trials. PATIENTS AND METHODS: Sixty patients were randomized to receive either arm A (cisplatin 25 mg/m(2) day 1, weekly for 9 weeks, irinotecan 90 mg/m(2) day 1, on weeks 1, 3, 5, 7 and 9, and etoposide 60 mg/m(2) days 1-3, on weeks 2, 4, 6, 8), or arm B (cisplatin 60 mg/m(2) day 1, irinotecan 60 mg/m(2) days 1, 8, 15, and etoposide 50 mg/m(2) days 1-3, every 4 weeks for four cycles). Prophylactic granulocyte colony-stimulating factor support was provided in both arms. RESULTS: Full cycles were delivered to 73% and 70% of patients in arms A and B, respectively. Incidences of grade 3-4 neutropenia, anemia, thrombocytopenia, infection and diarrhea were 57, 43, 27, 7 and 7%, respectively, in arm A, and 87, 47, 10, 13 and 10%, respectively, in arm B. A treatment-related death developed in one patient in arm A. Complete and partial response rates were 7% and 77%, respectively, in arm A, and 17% and 60%, respectively, in arm B. Median survival time was 8.9 months in arm A, and 12.9 months in arm B. CONCLUSIONS: Arm B showed a promising complete response rate and median survival with acceptable toxicity in patients with E-SCLC, and should be selected for the investigational arm in phase III trials.
