Correlations of Ezrin Expression with Pathological Characteristics and Prognosis of Osteosarcoma: A Meta-Analysis

Abstract EN

We conducted a meta-analysis to comprehensively evaluate the correlations of ezrin expression with pathological characteristics and the prognosis of osteosarcoma.

The MEDLINE (1966–2013), the Cochrane Library Database, EMBASE, CINAHL, Web of Science (1945–2013), and the Chinese Biomedical Database were searched without language restrictions.

Meta-analyses conducted using STATA software were calculated.

Ten studies met the inclusion criteria, including 459 patients with osteosarcoma.

Meta-analysis results illustrated that ezrin expression may be closely associated with the recurrence of osteosarcoma or metastasis in osteosarcoma.

Our findings also demonstrated that patients with grade III-IV osteosarcoma showed a higher frequency of ezrin expression than those with histological grade I-II osteosarcoma.

Furthermore, we found that patients with positive expression of ezrin exhibited a shorter overall survival than those with negative ezrin expression.

The results also indicated that positive ezrin expression was strongly correlated with poorer metastasis-free survival.

Nevertheless, no significant relationships were observed between ezrin expression and clinical variables (age and gender).

In the current meta-analysis, our results illustrated significant relationships of ezrin expression with pathological characteristics and prognosis of osteosarcoma.

Thus, ezrin expression could be a promising marker in predicting the clinical outcome of patients with osteosarcoma.
