Strategies and results of oncofertility counseling in young breast cancer patients

14 (21%) were childless at the moment of diagnosis. After being informed about the therapy, prognosis, side effects and oncofertility, 12 patients (18%) decided to have a consultation with a specialist in reproductive medicine; 5 of them (7%) already had children. In 2 women (3%), hormonal stimulation in combination with tamoxifen was used; then, oocytes were collected and cryopreserved. In 19 (28%), gonadotropine analogues were added to (neo-)adjuvant chemotherapy. In 17 patients (25%) pathogenic mutations in BRCA1/2 genes were found. Conclusions. Oncofertility counseling in young BC patients should be one of the fundamental elements of complex patient care.
