Abstract

We investigated the expression and prognostic significance of matrix metalloproteinase (MMP) -7, its relation to β-catenin expression and clinicopathological factors in epithelial ovarian cancer. The expression of MMP-7 was analyzed immunohistochemically in a series of 284 primary epithelial ovarian cancers, their 36 metastases and 8 normal ovaries. In cancers with endometrioid histology, a high percentage area of MMP-7 expression and an intense MMP-7 signal was significantly associated with nuclear positivity of β-catenin in cancer cells (p = 0.003, χ2 = 8.853 and p = 0.030, χ2 = 4.713, respectively). In all tumors and nonendometrioid subgroup, a low percentage area of MMP-7 positive tumor cells was significantly correlated with a high histological grade of the tumor (p = 0.003 and 0.005, respectively), in all tumors also with advanced stage of the tumor (p = 0.002) and large primary residual tumor (p = 0.005). A 10-year disease-related survival (DRS) was significantly better when the percentage area of MMP-7 expression in cancer cells was high, when compared to low (p = 0.0008). A high percentage area of intense MMP-7 signal in cancer cells predicted a significantly more favorable DRS and recurrence-free survival (RFS) (p = 0.0003 and 0.0052, respectively). In multivariate analysis, a high percentage area of intense MMP-7 signal in tumor cells was an independent prognostic factor, predicting favorable DRS and RFS. The present study showed that intense MMP-7 signal in tumor cells is an independent prognostic factor predicting better survival in epithelial ovarian cancer. © 2006 Wiley-Liss, Inc.
