enzalutamide in metastatic or advanced non-resectable granulosa cell ovarian tumors: greko iii study

Conditions: Ovarian Cancer

Summary: the good tolerability profile of enzalutamide, the fact that the administration of steroids is not necessary and the impressive results achieved in prostate cancer, make this drug an ideal candidate to be tested in ovarian granulosa cancer, a tumor that could somehow be considered as "female prostate cancer".
