Abstract: | OBJECTIVE: The enzyme matrix metalloproteinase (MMP)-1 is involved in ovarian carcinogenesis. A common guanine insertion-deletion promoter polymorphism within the gene encoding MMP-1 (MMP1) has been suggested to be a candidate gene for ovarian cancer. We investigated whether this common polymorphism can also serve as independent prognostic parameter in a large series of affected women. METHODS: The MMP1 promoter polymorphism was examined in 151 Caucasian patients with epithelial ovarian cancer using polymerase chain reaction. Results were correlated with clinical data. RESULTS: No associations were ascertained between the MMP1 polymorphism and tumor stage (P = 1.0, odds ratio [OR] 1.08), lymph node involvement (P = 1.0, OR 0.8), tumor grading (P = 0.2, OR 0.5), and patient's age at diagnosis (P = 1.0, OR 1.04). Besides the clinically established prognosticators, tumor stage and histological grade, presence of the MMP1 polymorphism was associated with a shortened disease-free and overall survival in a univariate Kaplan-Meier analysis (P = 0.01) and a multivariate Cox regression model (P = 0.04). CONCLUSION: Presence of the MMP1 gene promoter polymorphisms was found to be a negative prognostic parameter in patients with ovarian cancer. |
