Docetaxel and carboplatin as second-line chemotherapy for metastatic non-small cell lung cancer

The aim of this pilot study was to evaluate the activity and toxicity of docetaxel plus carboplatin as second-line treatment in patients with metastatic non-small cell lung cancer (NSCLC). Patients received docetaxel 75 mg/m(2) followed by carboplatin AUC 5 on day 1 every 3 weeks in an out-patient setting. Twenty-six patients were enrolled; 23 patients were diagnosed stage IV disease and three patients had a IIIB disease with malignant pleural effusion. The median interval from first to second-line treatment was 3.5 months (range 1-13). Patients received a total of 101 cycles with a median number of four cycles per patient (range 1-6). Five patients achieved a partial remission (19.23%; 95% confidence interval (CI) 6.55-39.35%), 11 had stable disease (42.31%) and ten progressed (38.46%) after initiation of second-line therapy. Median survival was 243 days (95% CI 182-336 days), the median progression-free survival was 118 days (95% CI 89-170 days), and the 1-year survival rate was 25.98% (95% CI 6.33-45.63%). Moderate haematological and mild nonhaematological toxicities were observed. No treatment-related death occurred. In conclusion, docetaxel plus carboplatin as second-line regimen has a reasonable activity with good tolerance and encouraging survival data.
