Abstract 4158
Background
Ovarian functions in premenopausal breast cancer patients are frequently affected due to the applied chemotherapy regimen. In this study, we aimed to evaluate the ovarian functions after chemotherapy by assessing the AMH, the number of antral follicle and the volume of ovaries in the premenopausal patients with breast cancer.
Methods
Fifty-one premenopausal operable breast cancer patients who were given adjuvant and neoadjuvant chemotherapy were included in our study. We planned to evaluate the change of serum AMH levels throughout the timeline of the study and ovarian volume-antral follicle numbers measured by transvaginal ultrasonography. First measurements were performed before chemotherapy and repeated in every following 3 months for one-year follow-up period.
Results
Interim third month and initial results of 31 patients were evaluated. Median age: 39 (range: 23-48). The results of 31 patients' 3rd AMH results and the measurements of ovarian volumes and antral follicle numbers of 28 patients were recorded prospectively from database. Initial AMH levels and 3rd follow-up AMH levels were compared revealing statistically significant decrease (p = 0.000). When pre- and post-chemotherapy measurements were compared right and left ovary volumes and antral follicle numbers demonstrated statistically significant decrease after chemotherapy (p = 0.000).
Conclusions
Preliminary data of this study showed that 3rd month AMH levels, antral follicle numbers and ovarian volumes were significantly lower in contrast to pretreatment measurements. By the end of study period we aimed to evaluate the effects of different chemotherapy regimens on ovarian function and predictive strength of utilized markers for evaluation of ovarian function.
