Clinicopathologic study of the putative precursor lesions of epithelial ovarian cancer in low-risk women.
Possible precursor lesions for epithelial ovarian cancer (EOC) have been defined in the ovaries of women with contralateral EOC, with breast cancer susceptibility gene (BRCA)-1 mutations, or with positive family history. We aimed to investigate the prevalence of these lesions in women without any recognizable risk and to correlate these lesions with clinical ovulatory markers. The study group consisted of 184 women who were operated for benign gynecological conditions. Patients were requested to fill a questionnaire about anthropometric characteristics and medical and reproductive history. Oophorectomy specimens were examined for presence of epithelial inclusion cysts (EIC), cortical invaginations (CI), stromal hyperplasia (SHPP), epithelial pseudostratification (EPS), and surface papillomatosis (SP). Women with EIC were older, had lower age at menarche, and had higher menarche-to-pregnancy and menarche-to-operation time. SHPP was found to be related with age, menarche-to-operation time, history, and the duration of oral contraceptive use. Women with SP had lower age at menarche, lower menopausal age, and longer duration of hormone replacement therapy. No significant correlations were established between CI and any clinical parameters. Only one patient had EPS. Our findings suggest that these lesions correlate closely with reproductive features. Exact mechanisms that lead to development of these lesions should be clarified before implying them as precursor lesions of EOC.
