ObjectiveTo systematically review the predictive value of ezrin expression in bone and soft tissue sarcomas.MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 2, 2016), CNKI, CBM, VIP, and WanFang Data were searched to collect cohort studies about the prognostic value of ezrin expression in bone and soft tissue sarcomas from inception to May 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software.ResultsFinally, a total of 17 cohort studies, involving 1 460 patients were included. The results of meta-analysis showed that: the overall survival (HR=1.90, 95%CI 1.70 to 2.13, P<0.000 01), event-free survival (HR=2.42, 95%CI 1.53 to 3.84, P=0.0002), metastasis-free survival (HR=2.09, 95%CI 1.10 to 3.97, P=0.02) in the bone and soft tissue sarcomas patients with ezrin high expression were lower than patients with lower expression. The same results were also observed in subgroup analysis according to histologica type and ethnicity in overall survival.ConclusionEzrin high expression may be used as a predictive maker for poor prognosis in bone and soft tissue sarcomas. For the quantity and quality limitation of the included studies, this conclusion still needs to be further proved by performing more high quality studies.
