[Autoantibodies to steroid-producing ovarian cells in cancer patients]

Our investigation included 158 women, aged 23-73: patients with tumors of the ovary, breast and endometrium--117 and subjects without oncological pathology--41. Autoantibodies to microsomal fraction of follicular ovarian cells (> 500 Unit/ml) in healthy subjects were revealed 8.3% while in patients with ovarian, breast and endometrial malignancies (without significant differences between benign and malignant tumors) in 33.30%, 45.60% and 25.0%, respectively. Higher level of anti-ovarian autoantibodies involved an inverse correlation between blood levels of FSH and estradiol in ovarian and endometrial carcinoma patients. It also co-occurred with a tendency of increasing levels of autoantibodies to thyroglobulin. Whatever apparent predictive accuracy in oncological clinic, high concentrations of anti-ovarian autoantibodies point to certain shifts taking place in the formation of reproductive system pathology. Besides, they may have considerable prognostic significance.
