OBJECTIVE: Docetaxel and carboplatin (DC) have demonstrated activity as radiation sensitizers in pre-clinical studies. The aim of this phase II study was to evaluate the efficacy and toxicity of DC with concurrent thoracic radiation therapy (TRT) followed by consolidation chemotherapy with DC for stage III unresectable non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Thirty-three previously untreated patients with inoperable, locally advanced (LA) NSCLC received docetaxel 30 mg/m2 over 1 h and carboplatin at an AUC of 3 every 2 weeks for six courses--four courses during concurrent chemoradiotherapy and two courses following completion of radiotherapy. Concurrent TRT was performed in 2-Gy daily fractions to a total dose of 60 Gy. RESULTS: Among 32 evaluable patients, the overall response rate was 91%, with two complete responses (CR) and 27 partial responses (PR). Median survival time by intention-to-treat analysis was 27 months, with survival rates of 76% at 1 year and 61% at 2 years. Serious side effects were generally limited to grade 3 neutropenia in 6%, grades 3 and 4 pulmonary toxicity in 6 and 3%, respectively, and grade 3 esophagitis in 3% of patients. CONCLUSIONS: DC with concurrent TRT followed by consolidation chemotherapy was highly active with manageable toxicity in patients with stage III unresectable NSCLC.
