Randomised, multicentre phase II study assessing two doses of docetaxel (75 or 100 mg/m2) as second-line monotherapy for non-small-cell lung cancer
2004
Background: The survival benefit associated with first-line chemotherapy in advanced lung cancer led to the need for second-line chemotherapy. Docetaxel (Taxotere®) has proven efficacy in both settings. This study evaluated the safety and efficacy of two doses of docetaxel in patients with non-small-cell lung cancer who had failed first-line platinum-based chemotherapy. Patients and methods: In total, 182 patients from 24 French centres were randomised and treated with either docetaxel 75 mg/m 2 (arm A) or 100 mg/m 2 (arm B) every 3 weeks. Baseline characteristics were well balanced, except more patients in arm A had metastatic disease (91.4% versus 78.7%) and therefore the median number of sites involved for arm A was three compared with two for arm B. Results: Median time to treatment failure was 1.34 months [95% confidence interval (CI) 1.28-1.64] for arm A and 1.64 months (95% CI 1.34-2.62) for arm B. Median overall survival was 4.7 months (95% Cl 3.8-5.9) for arm A versus 6.7 months (95% CI 4.8-7.1) for arm B. According to a blinded expert panel, disease control was achieved in 35 (43.8%) patients in arm A and 39 (49.4%) patients in arm B. More patients in arm B experienced grade 3-4 neutropenia (B: 72.7% versus A: 44.0%), asthenia (B: 20.2% versus A: 10.8%) and infection (B: 6.7% versus A: 2.2%). Three treatment-related deaths were reported in each arm. Conclusions: The optimal docetaxel dosage in this second-line setting is 75 mg/m 2 , as it has a more favourable safety profile and on balance a similar efficacy to the 100 mg/m 2 dose.
