[Cisplatin etoposide versus cisplatin/etoposide/ifosfamide combination chemotherapy in small-cell lung cancer: a multicenter randomized controlled study. Hokkaido Study Group of Treatment for Small-Cell Lung Cancer].
Ninety-two patients with small-cell lung cancer (SCLC) were randomized to receive cisplatin (80 mg/m2, day 1)/etoposide (100 mg/m2, day 1, 3, 5) (PE) or cisplatin (80 mg/m2, day 1)/etoposide (100 mg/m2 1, 3, 5)/ifosfamide (2 g/m2, day 1, 2, 3) (PEI) combination chemotherapy. After 2 courses of chemotherapy, patients with limited disease (LD) received chest irradiation with 40-50 Gr. Of the 89 patients evaluable, the overall response rate was 77.8% in PE therapy, and 73.7% in PEI therapy (NS). The complete response rate (CR) of PE v PEI was 13.9% v 21.2% for all patients (NS), 22.2% v 30.4% for LD. Median survival times of PE v PEI for all patients were 55 weeks v 56 weeks (NS). The 2-year survival rate of PE v PEI was 15.4% v 16.5% for all patients (NS). There was no difference of the duration of response in cases with CR or PR between PE and PEI therapy. Leucopenia occurred more often after PEI than after PE therapy (p less than 0.01). These results suggest that PEI is not superior to PE chemotherapy in SCLC.
