Abstract

Objective To evaluate the association of tumor-derived matrix metalloproteinase 2 (MMP-2) and stromal-derived MMP-2 expression with the prognosis of patients with ovarian cancer, a meta-analysis study was performed, which was aimed to comprehensively review the evidence of MMP-2 as prognostic biomarkers in ovarian cancers.

Methods All relevant studies were searched in PubMed and Web of Science until May 30, 2014. Hazard ratios (HRs) with their 95% confidence intervals (CIs) were used to assess the association between MMP-2 expression (tumor-derived or stromal-derived) and prognosis of patients with ovarian cancer. Pooled odds ratios (ORs) and their 95% CIs were used to assess the correlation of MMP-2 expression with the clinicopathological features of patients with ovarian cancer.

Results A total of 965 patients in 8 studies were included in this analysis. Among them, tumor-derived and stromal-derived MMP-2 expression was detected in 7 and 5 articles, respectively. The results revealed that ovarian cancer patients with positive tumor-derived MMP-2 expression showed a worse prognosis than did the ones with negative tumor-derived MMP-2 expression (HR, 1.52; 95% CI, 1.06–2.20). However, ovarian cancer patients with positive stromal-derived MMP-2 expression had not. In addition, we also found that tumor-derived MMP-2 expression was associated with distant metastasis (absent vs present; pooled OR, 4.52; 95% CI, 1.56–13.09; P = 0.001).

Conclusions These results suggested that positive tumor-derived MMP-2 expression could predict a lower overall survival rate and could be an independent dangerous prognostic factor in patients with ovarian cancer.
