Irinotecan compared with etoposide in combination with platinum in previously untreated extensive stage small cell lung cancer: An updated systemic review

摘要

Objective: To compare the therapeutic effect of irinotecan/platinum (IP) and etoposide/platinum (EP) in treatment-na?ve extensive small cell lung cancer patients. Methods: Systematic computerized searches of PubMed database and Chinese National Knowledge Infrastructure were performed. Summary odds ratio (OR) or hazard ratio (HR), and 95% confidence intervals (95% CI) were used to compare IP with EP in previously untreated small cell lung cancer patients. Results: A total of 10 randomized trials were included in the analyses. The result showed the patients treated with irinotecan combinations experienced longer overall survival than epotoside, the pooled HR was 0.85 (95% CI = 0.78-0.92). The pooled OR revealed that IP stated better objective overall response than EP regimens (OR = 1.10, 95% CI = 0.92-1.32). Treatment-related deaths were similar between the two groups. Conclusion: IP regimens could be used as first-line treatment for extensive stage small cell lung cancer patients.
