[Evaluation of gonadal hormone function in adolescent girls after antineoplastic therapy].

In 17 girls after the complex anti-neoplasm therapy we estimated the state of genital organs and the course of menorrhagia cycle together with plasma levels of beta-estradiol, progesterone and prolactin assessed by RIA. We found the secondary lack of menorrhagia together with lowered progesterone and beta-estradiol levels in 3 girls, in whom the abdominal cavity was irradiated. In other 3 girls the transient lack of menorrhagia was stated in the course of chemotherapy.
