Premenopausal advanced breast cancer patients who failed tamoxifen treatment are possible good candidates for ovarian ablation/suppression and aromatase inhibitors.Fulvestrant has been studied little in premenopausal women despite of its attractive mechanism of actions. Based on this rationale, we introduced high-dose of fulvestrant with LHRH agonist as a randomized trial comparing with AI plus LHRH agonist.~To assess efficacy of goserelin plus fulvestrant 500mg comparing with goserelin plus anastrozole as first line endocrine therapy for pre- and perimenopausal HR+ advanced breast cancer in terms of progression-free survival(PFS)
The purpose of this study is to assess the efficacy of goserelin plus fulvestrant 500mg comparing with goserelin plus anastrozole as first line endocrine therapy for pre- and perimenopausal HR+ advanced breast cancer.
