Abstract

Bevacizumab when combined with carboplatin and paclitaxel improves response rates (RRs) and overall survival in patients with advanced non-small cell lung cancer. Paclitaxel has single-agent activity in relapsed small cell lung cancer (SCLC). Angiogenesis seems to play an important role in the pathogenesis of SCLC. This study evaluated the safety and efficacy of paclitaxel plus bevacizumab in patients with chemosensitive relapsed SCLC. Methods: Patients with relapsed chemosensitive SCLC with an Eastern Cooperative Oncology Group performance status of 0 to 1 were eligible. They received paclitaxel 90 mg/m2 intravenously on days 1, 8, and 15. Bevacizumab was administered at 10 mg/kg intravenously on days 1 and 15. Cycles were every 28 days. The primary endpoint was progression-free survival (PFS). Secondary endpoints included RRs, toxicity, and overall survival. Correlative studies evaluated vascular endothelial growth factor polymorphisms. Results: Thirty-four patients were enrolled in the study. Median age was 66.5 (range, 38-88) years, male:female: 61.8%:38.2%, Eastern Cooperative Oncology Group performance status 0:1 47.1%:52.9%. Median progression-free survival was 14.7 weeks (equivalent to historical controls). Median survival time was 30 weeks. The overall RR was 18.1%. Stable disease rate was 39.3%, and 45.4% of patients had progressive disease. No unexpected toxicities were noted, and grade 3/4 toxicities were limited to neutropenia, fatigue, and dyspnea. None of the vascular endothelial growth factor polymorphisms evaluated were significantly associated with response. Conclusions: The addition of bevacizumab to paclitaxel does not improve outcomes in relapsed chemosensitive SCLC.
