[Meta-analysis on elemene injection combined with cisplatin chemotherapeutics in treatment of non-small cell lung cancer].

To research databases of Cochrane library, Web of Science, PubMed, FMJS, CBM, VIP, CNKI and Wanfang Data Konwledge Service Platform by computers as at July 5, 2012, which was supplemented with other search results. The findings were included into randomized controlled trials (RCTs) of elemene injection combined with cisplatin chemotherapeuties in treating small cell lung cancer (NSCLC). Data was separately collected by two researchers for literature quality evaluation, and a Meta analysis was made with RevMan 5. 2 software, in order to assess the efficacy and safety of elemene injection combined with cisplatin chemotherapeutics in treating NSCLC. Totally 11 RCTs or 844 cases were included. Meta analysis results suggested that compared with cisplatin chemotherapy alone, the combination of elemene injection and cisplatin chemotherapeutics showed a higher clinical benefit rate ( OR = 2. 03, 95% CI:1.43-2. 88, P <0. 000 1) and a better quality of life (OR = 3.23, 95% CI:2. 20-4. 74, P <0. 000 01). Besides,the combination could also reduce leucopenia (OR =0. 50, 95% CI:0. 33-0. 76, P <0. 001) , and thrombocytopenia (OR =0. 38, 95% CI:0. 16-0. 85, P <0. 02), increase CD4 (MD = 3.32, 95% C1:2. 94-3.70, P <0. 000 01), and CD4/CD8 (MD = 0. 36, 95% CI:0. 28-0. 44, P < 0. 000 01) , and relieve gastrointestinal reactions such as nausea and vomiting (OR = 0. 37, 95% CI: 0. 19-0. 71, P = 0. 003). The analysis indicates that elemene can enhance the chemotherapeutic effect on NSCLC, improve the quality of life, and reduce adverse effect of platinum-contained chemotherapeutics, thereby being worth promoting in clinic.
