| Abstract: | PURPOSE: The aim of this phase II trial was to evaluate the efficacy and safety of a combination chemotherapy containing irinotecan (CPT-11) and carboplatin as first-line treatment of patients with small cell lung cancer (SCLC). PATIENTS AND METHODS: From December 2002 to May 2004 61 patients with limited disease (IASLC classification) were enrolled who were not suitable for concurrent chemo-radiotherapy. Eighteen of the 61 patients (29.5%) had malignant pleural or pericardial effusion and 4 patients (6.6%) had involved supra- or infraclavicular lymph nodes. Patients received irinotecan 50mg/m(2) on days 1, 8 and 15 and carboplatin AUC 5 on day 1, every 4 weeks. RESULTS: A total of 233 chemotherapy cycles were administered. The median number of cycles per patient was 4. The overall response rate to chemotherapy on an intention-to-treat basis was 64%. The median overall survival was 13.8 months, the median disease-free survival 8.0 months, the 1-year survival rate 53.5%, and the 2-year survival rate 17.9%. Haematological and non-hematogical toxicities were low (CTC-grade 3 neutropenia 14.8%, grade 3 thrombocytopenia 5.2%, grade 3/4 anemia 5.1%, grade 3 nausea/vomiting 5.1%, grade 3 diarrhea 3.6%, grade 3 alopecia 3.6% of pts). CONCLUSION: The results suggest that the combination of irinotecan (CPT-11) and carboplatin is active and well tolerable in patients with limited disease SCLC who were not suitable for concurrent chemotherapy. |
