Background:
Numerous studies examining the relationship between CD44 expression and prognostic impact in patients with osteosarcoma have yielded inconclusive results. The aim of this meta-analysis was carried out to investigate the relationship between CD44 expression and the survival in patients with osteosarcoma.
Methods:
We therefore conducted a meta-analysis to provide a comprehensive evaluation of the prognostic role of CD44 expression on the overall survival rate and metastasis, which compared the positive and negative expression of CD44 in patients of the available studies.
Results:
A detailed search was made in MEDLINE and EMBASE for relevant original articles published in English. Finally, a total of six studies with 329 osteosarcoma patients were involved to estimate the relationship between CD44 expression and metastasis of tumor and overall survival. Positive expressions of CD44 did not predict neoplasm metastasis (RR = 1.36, 95% CI: 1.00-1.84, P = 0.50), and the results indicated that higher expression of CD44 could not predict poorer survival in osteosarcoma with the pooled HR of 0.55 (95% CI: 0.27-1.13, P = 0.47).
Conclusions:
The findings from this present meta-analysis suggest that CD44 expression is not associated with overall survival rate and metastasis in osteosarcoma.
