Abstract/Text
PURPOSE: To compare the efficacy and toxicities of irinotecan/ platinum (IP) with etoposide/platinum (EP) in patients with previously untreated extensive-stage small cell lung cancer (E-SCLC).
METHODS: The PubMed database, the Cochrane Library, conference proceedings, databases of ongoing trials, and references of published trials and review articles were searched. Two reviewers independently assessed the quality of the trials and extracted data. The relative risk for overall response to treatment, hazard ratios (HRs) for overall survival (OS) and progression-free survival (PFS), and odds ratios for the different types of toxicity were pooled by STATA package.
RESULTS: Six trials involving 1476 patients with previously untreated E-SCLC were ultimately analyzed. The intention-to-treatment analysis indicated that IP regimens could acquire more overall response than EP regimens (relative risk = 1.10, 95% confidence interval [CI]: 1.00 -1.21, p = 0.043). The pooled HR showed that IP could prolong OS (HR = 0.81, 95% CI: 0.66 -0.99, p = 0.044). Nevertheless, the pooled HR failed to show a favorable PFS in IP regimens (HR = 0.82, 95% CI: 0.64 -1.06, p = 0.139). IP regimens led to less grade 3 to 4 anemia, neutropenia, and thrombocytopenia but more grade 3 to 4 vomiting and diarrhea than EP regimens. Treatment-related deaths were comparable between the two groups.
CONCLUSION: Although the PFS was similar from this meta-analysis, our results suggest that IP might have an advantage in overall response and OS compared with EP with less hematological toxicities. The IP regimens may be an alternative of EP regimens in the first-line treatment of E-SCLC.
