Abstract

The fallopian tubes and ovaries samples from 5 breast cancer patients and 12 practically healthy women considered to be at high risk for developing ovarian cancer underwent evaluation for morphological features and immunohistochemical expression of Ki-67 and p53. In high-risk patients the multiple follicular, serous, epithelial inclusion cysts (often with epithelial hyperplasia), surface papillomatosis, fibromatosis, cortical stromal hyperplasia in ovaries and fibres' sclerosis, paratubal cysts in fallopian tubes were discovered. Immunohistochemical study revealed strong expression of Ki-67 (LI 16-53,6%) in epithelial cells of follicular and inclusion cysts in 25% (3/12) of practically healthy women of reproductive age. P53 expression was determined in epithelium of inclusion cysts with high proliferative activity in 16,6% (2/12) of practically healthy women with BRCA1/2 mutation. The current results suggest histological evidence for the existent of pre-neoplastic phenotype defined by above-described histologic features in the high-risk ovaries, especially in carriers of BRCA1/2 mutations. P53 and Ki-67 expression in epithelium of inclusion cysts in women with BRCA1/2 mutations indicates the early genetic alterations in these cells and high risk of malignant transformation.
