Etoposide and split-dose cisplatin in small-cell lung cancer.
Forty-seven untreated patients with small-cell lung cancer (SCLC) were treated with a combination of etoposide (170 mg/m2 intravenously, i.v., days 3-5) and cisplatin (50 mg/m2 i.v., days 1 and 7). Responding patients with limited disease received four cycles followed by irradiation (delivered to the primary site, mediastinum, and supraclavicular region) with 50 Gy. Prophylactic cranial irradiation (PCI) with 30 Gy was performed in patients who achieved complete remission. Responding patients with extensive disease received four to six cycles of chemotherapy. The overall objective response rate (complete response plus partial response, CR + PR) was 94% (44 of 47). CR rate (all patients) was 57% (27 of 47), 51% (19 of 37) in extensive disease and 80% (8 of 10) in limited disease. The median remission duration is 13 months (12 months in extensive disease and 26 months in limited disease). The median survival is 16 months for all patients (15 months in extensive disease, 28 months in limited disease). Mean follow-up is 13 months. Toxicity was primarily hematologic. Twelve of 47 patients had leukopenia of WHO grade 4, 30 of 47 of grade 3. Thrombocytopenia of WHO grade 3 and 4 occurred in 6 of 47 and 2 of 47 patients, respectively. There were four severe infections in neutropenic patients, but no chemotherapy-related lethal complications. The only treatment-related death was that of one patient who died in CR of progressive neurologic dysfunction 11 months after PCI. This schedule of etoposide and cisplatin induces high CR rates and a prolonged survival, especially in patients with extensive disease.
