Abstract

Background: Controlled ovarian hyperstimulation (COH) followed by oocyte retrieval is a leading option for fertility preservation before chemotherapy, yet this procedure causes excessive serum levels of estradiol (E2), which are often detrimental for cancer patients. Aromatase inhibitors are often used in breast cancer patients during COH to prevent elevated levels of E2. Objectives: To describe our experience with COH for oocyte cryopreservation in non-breast cancer patients using aromatase inhibitors. Methods: Of the five patients treated, two had an aggressive abdominal desmoid tumor, one had endometrial carcinoma, one had uterine sarcoma, and one patient had a brain oligoden-droglioma. In all cases the treating oncologist suggested an association between estrogen and possible tumor progression. All patients were treated with a standard in vitro fertilization antagonist protocol combined with aromatase inhibitors, similar to the protocol used for breast cancer patients. Results: The average duration of treatment was 10.5 days, mean peak E2 was 2348 pmol/L, mean number of oocytes aspirated was 17.3, and a mean of 14.6 embryos/oocytes were cryop-reserved. Conclusions: COH with aromatase inhibitors is apparently effective in non-breast cancer patients and spares exposure to high E2 levels.
