The standard treatment for brain metastases is whole brain radiation, but the medium survival is about 3-10 months and hadn't be improved for years. This study was to evaluate the effect of antineoplastic therapy combined with whole brain radiation for brain metastases. We searched PubMed, EMBASE, Cochrane Library, Chinese Biomedical Literature Database, China Journal Full Text Database and references of the included studies up to May 2011. Randomized controlled trials involving antineoplastic combined with whole brain radiation compare with whole brain radiation alone for brain metastases were analysed. Study selection, data collection and quality assessment of studies were performed by two individual reviewers according to the Cochrane Handbook for systematic reviews of interventions 5.0.2. Statistic analyses were calculated using RevMan5.0.17 software. 9 randomized controlled trails, a total of 1582 patients were included. There were no significant differences in overall survival, six to twenty-four months survival rate and death from central nervous system (CNS) cause, only the objective response rate was statistically higher in the combined group. (RR = 1.47, 95% CI: 1.10, 1.97; p = 0.009) Subgroup analysis of lung cancer got the same result, except that death from central nervous system (CNS) cause was higher in the combined therapy group, it was statistical significant (RR = 0.70, 95% CI: 0.53, 0.93; p = 0.01). The benefit of antineoplastic combined with whole brain radiation for brain metastases was not concerned, either in the brain metastases from unselected primary tumors or lung cancer.
