[Hormonal therapy of advanced or relapsed ovarian granulosa cell tumor]

Ovarian granulosa cell tumor is a rare gynecologic malignancy with hormonal activity. Surgical excision is the standard treatment for this disease. Most patients present excellent short term prognosis, however, late relapse often occurs, even after many years. Viable treatments of advanced or relapsed granulosa cell tumor are still limited, and the optimal therapy method has not been established. Compared with chemotherapy and radiotherapy, hormonal therapy is a well-tolerated treatment which can be administrated over a long period of time without serious side effects, and the combined application of hormones may achieve a better outcome. Therefore, hormonal therapy has been suggested as a potential treatment option for patients with advanced or relapsed granulosa cell tumor, and to extend the tumor-free interval and attenuate the disease progression. Future researches should be focused on the identification of the hormonal therapy which may provide the greatest clinical benefit, comparing and analyzing the effects of different combined therapeutic regimens of hormone drugs, and on the synthesis of drugs highly activating estrogen receptor β expressed in the granulosa cell tumor cells.
