Summary Introduction: One of the most commonly assessed angiogenesis markers is microvessel density which is determined on the bases of specific endothelial antigen expression (CD34, CD105). Angiogenesis modulators include growth factors and their receptors (EGFR), proteases and their inhibitors, oncogenes and suppressor genes (p53). Objective: The aim of the study was to evaluate whether there are any differences in selected angiogenesis markers and modulators expressions in ovarian cancer patients with different menopause status. Material and methods: The study included 100 women, age 30-70, who underwent surgical treatment due to ovarian cancer. As far as their menopause status was concerned, the women were divided into three groups: pre-, peri-, and postmenopausal. Microvessel density was assessed on the basis of CD34 (MVDCD34) and CD105 (MVDCD105) expression. Additionally, tumor tissue p53 protein and EGFR expression were investigated. Active EGFR form in blood serum samples of cancer patients was assessed before the surgery. Results: Microvessel density, assessed on the basis of CD34 and CD105 expression, as well as p53 and EGFR expression were similar in all three groups of patients. Active EGFR serum concentration in women with ovarian cancer did not prove to be significantly different and did not depend on the menopause status. Conclusion: Intensity of the angiogenesis process does not depend on the menopausal status of women and is similar in pre-, peri- and postmenopausal patients.
