OBJECTIVES: The aim of this work was to determine gonadotropin (LH, FSH) levels in serum and cyst fluid in various type of ovarian epithelial neoplasms (benign, borderline, malignant) and to compare them with levels in benign cysts. Additionally we decided to estimate if there were some significant correlations between serum and ovarian cyst fluid in gonadotropin levels in all investigated groups. MATERIALS AND METHODS: The study group included 74 patients before (n=36) and after (n=38) menopause, divided into four groups depending on the histopathologic diagnosis. Serum and cyst fluid levels of LH and FSH were determined in all patients. RESULTS: We found statistically significant differences concerning LH and FSH levels in serum and cyst fluid between malignant and borderline tumors, between malignant tumors and benign cystadenomas and between malignant tumors and non-neoplastic cysts. We also found statistically significant correlations between serum and cyst fluid as to FSH and LH levels in patients with borderline tumors. There were no statistically significant correlations between serum and cyst fluid as to FSH and LH levels in patients with malignant epithelial tumors (group 1) and in patients with benign cystadenomas (group 3). CONCLUSIONS: High FSH and LH levels in cyst fluid of malignant epithelial tumors of the ovary are in line with the gonadotropin theory of tumor growth. Simultaneous determination of various types inhibin levels appears to be an interesting topic for our future research.
