文摘

CD105 is an ancillary receptor of transforming growth factor beta (TGF-β), which has been suggested as a suitable biomarker for cancer-related angiogenesis and neovascularization (Nassiri et al. in Anticancer Res 31:2283–2290, 2011). However, the clinical significance of CD105 in WHO grade was rarely reported and the effects of CD105 signal transduction pathway on gliomas remain controversial and unclear. To get a convincing conclusion, performing a meta-analysis is essential. Relevant literature studies were included via careful evaluation, and standard mean difference (SMD) and hazard ratio (HR) with 95 % confidence intervals (95 % CIs) was calculated. We also made funnel plots to test the heterogeneity. In the present meta-analysis, a total of 11 eligible literatures involving 796 patients were incorporated. They were all conducted in China, revealing that CD105 overexpression in glioma tissues was strongly linked to high WHO grading (III+IV) (SMD −1.785, 95 % CI −2.133, −1.437; p = 0.000). No significant associations between CD105 and age (SMD −0.505, 95 % CI −1.054, 0.043; p = 0. 071), CD105 and gender (SMD 0.101, 95 % CI −0.103, 0.305; p = 0.333), and CD105 and tumor size (SMD −0.433, 95 % CI −1.326, 0.459; p = 0. 341) were detected. Besides, CD105 expression was closely associated with glioma patients’ 3-year overall survival (OS; n = 2; HR = 4.357, 95 % CI 1.412, 7.303; p = 0.004). On the basis of Begg’s and Egger’s test or funnel plot, no publication bias was detected. In a nutshell, this meta-analysis demonstrated that CD105 overexpression correlates to higher WHO grade and poor survival and could be indicated as a helpful prognostic and diagnostic marker, or a useful therapy target.KeywordsCD105GradeGliomaPrognosisMeta-analysis
