Background: This randomized phase II trial evaluated the efficacy and toxicity of oral topotecan compared with intravenous docetaxel in the second-line treatment of patients with non-small-cell lung cancer (NSCLC).
Patients and methods: Eighty patients were randomized to receive topotecan (2 mg per day or 2.5 mg per day fixed dose for 5 of 7 days for 2 weeks) or docetaxel (75 mg/m2) every 21 days. Thirty-nine patients received 138 cycles of topotecan.
Results: The overall response rate (RR; ORR) was 8%, median time to progression (TTP) was 1.6 months, median survival was 8.4 months, and the 1- and 2-year survival rates were 36% and 13%, respectively, for patients receiving topotecan. Forty-one patients were randomized, but only 38 patients were actually treated with 136 cycles of docetaxel. The ORR was 8% (7% intent to treat RR), median TTP was 1.4 months, median survival was 7.6 months, and the 1- and 2-year survival rates were 29% and 13%, respectively, for patients receiving docetaxel.
Conclusion: Oral topotecan appears to be active and well tolerated when administered as a fixed dose daily for 5 of every 7 days for 2 weeks every 21 days and might provide another treatment alternative for patients with advanced-stage NSCLC.
