Abstract
Cytovillin plays structural and regulatory roles in the assembly and stabilization of specialized plasma membrane domains and in the tumor angiogenesis. Cytovillin expression has been proposed to be an effective biomarker of prognosis in patients with osteosarcoma, and many studies have been performed to assess the prognostic role of cytovillin expression in patients with osteosarcoma. We performed this meta-analysis to provide a comprehensive evaluation of the role of cytovillin expression on the overall survival rate by calculating the pooled risk ratio (RR) with corresponding 95% confidence interval (95% CI). Finally, eight studies with a total of 415 patients with osteosarcoma were included into the meta-analysis. Meta-analysis of total eight studies showed that cytovillin expression was obviously associated with lower overall survival rate in patients with osteosarcoma (RR = 0.41, 95% CI 0.28–0.58, P < 0.001). Meta-analysis of five studies with large sample still showed that cytovillin expression was obviously associated with lower overall survival rate (RR = 0.48, 95% CI 0.38–0.60, P < 0.001). In conclusion, the meta-analysis shows that cytovillin expression is obviously associated with lower overall survival rate in patients with osteosarcoma, and it is an effective biomarker of prognosis.
