Fortunately current survival rates of BC are significant which makes future fertility very important for quality of life of BC survivors. Chemotherapy carries a significant risk of infertility in BC patients so it is important to support fertility preservation decisions in premenopausal women. Amenorrhea has long been used as a surrogate marker of infertility in cancer patients but more reliable ovarian reserve (OR) markers are available. This study aimed to prospectively measure levels of OR in a cohort of young women with breast cancer exposed to chemotherapy, to identify adverse reproductive health outcomes in this population and to assess the influence of patient and treatment-related factors in those outcomes. Methods: This prospective observational study included premenopausal women with breast cancer aged 18–40 years at diagnosis and proposed for (neo) adjuvant chemotherapy. Patients were evaluated before, during and a minimum of 9 months after the end of chemotherapy. Reproductive health outcomes: menses, hormonal and ultrasound OR markers, recovery of ovarian function and Premature Ovarian Insufficiency (POI). Results: A total of 38 patients were included (mean age 32.9 ± 3.5 years). Levels of OR significantly decreased during the study. At the last follow up, 35 patients had AMH below the expected values for age; eight presented postmenopausal FSH; ten had not recovered their ovarian function and five met the defined criteria for POI. Age and baseline AMH were positively correlated with AMH at the last follow-up. AMH levels were higher in the group of patients treated with trastuzumab and lower in those under hormonal therapy, at the last follow-up. Conclusions: Significant effects of systemic treatments on several reproductive outcomes and a strong relation of those outcomes with patient’s age and baseline level of AMH were observed. Our results point to a possible lower gonadotoxicity when treatment includes targeted therapy with trastuzumab. Also, this investigation highlights the lack of reliable OR markers in women under hormonal therapy. | URI: | https://hdl.handle.net/10316/107129 | ISSN: | 1757-2215 | DOI: | 10.1186/s13048-019-0581-6 | Direitos: | openAccess |
