Background: Amrubicin (AMR), a third-generation anthracycline and potent topoisomerase II inhibitor, has been known to be effective treatment for previously treated Extensive-Disease Small-Cell Lung Cancer (ED-SCLC). However, the efficacy and toxicityof amrubicin remainsconflicting . Thus,this meta-analysis was designed to evaluate amrubicin effectiveness in refractory ED-SCLC patients. Methods: Pubmed, Embase, Cochrane library databases were searched for the relevant articles. After rigorous evaluation on quality, the data extraction process was carried from eligible randomized controlled trials (RCTs). Meta-analysis Revman 5.3 software was used for statistical analysis. Results: A total of 7 RCTs were included in our analysis. The regimen of AMR was associate with better progression-free survival (PFS)(OR=0.81,95%CI=0.71-0.92, P=0.001), and the objective response rate (ORR) (OR=1.83,95%CI=1.37-2.45, P<0.0001=. While, there was no statistical significance was found in terms of the overall survival (OS) (OR=0.90,95%CI=0.79-1.03, P=0.12). The frequencies of the most common toxicities were more commonly occurred in the AMR group compared with the control group were neutropenia (OR=1.67, 95%CI=1.10-2.54, P= 0.02) and anemia (OR=0.47,95%CI=0.34-0.66, P<0.0001= , respectively. Conclusion: AMR was associated with better efficacy and acceptable side effects for the treatment-refractory ED-SCLC. The findings revealed that amrubicin may be used as second-line chemotherapy for patients with sensitive-relapse ED-SCLC.
