    Abstract:
    INTRODUCTION: The current standard of care for good performance status patients with locally advanced non-small cell lung carcinoma is concurrent chemoradiation, although a clearly superior regimen has not been identified. Docetaxel has been shown to possess good single-agent activity against non-small cell lung cancer (NSCLC) and radiosensitizing properties, both alone and synergistically with carboplatin. We undertook this phase II study to determine the safety and efficacy of weekly docetaxel-carboplatin and concurrent radiation therapy followed by docetaxel-carboplatin consolidation for the treatment of locally advanced NSCLC. METHODS: Sixty-seven patients having previously untreated stage IIIA or IIIB unresectable NSCLC were enrolled, with 61 patients evaluated for endpoints. Docetaxel 20 mg/m IV infusion over 30 minutes followed by carboplatin area under the curve = 2 over 30 minutes was administered weekly during concurrent thoracic radiotherapy. After 3 week rest, consolidation docetaxel 75 mg/m(2) IV infusion over 60 minutes and carboplatin area under the curve = 6 over 30 minutes was administered every 3 weeks for two cycles. Concurrent thoracic radiation consisted of 45 Gy (1.8 Gy fractions 5 d/wk for first 5 weeks) followed by 18 Gy boost (2.0 Gy fractions 5 d/wk for 2 weeks) for a total dose of 63 Gy. RESULTS: One and 2 years overall survival rates were 45 and 20%, respectively. Progression free survival at 1 year was 27%. Median survival time was 12 months. Median time to progression was 8 months. The primary hematologic toxicity was leukopenia. The primary nonhematologic toxicity was esophagitis. CONCLUSION: The administered regimen of weekly docetaxel-carboplatin and concurrent radiation therapy followed by docetaxel-carboplatin consolidation has acceptable toxicity profile. However, the overall survivals at 1 and 2 years are somewhat disappointing.
