TLDR
Fulvestrant has recently gained US Food and Drug Administration approval for the treatment of hormone receptor-positive metastatic breast cancer in postmenopausal women with disease progression following antiestrogen therapy and these new hormonal treatments expand the choice of endocrine therapy for women with advanced breast cancer.Abstract:
Since its introduction more than 30 years ago, tamoxifen has been the most widely used endocrine therapy for the treatment of women with advanced breast cancer. More recently, a number of alternative endocrine treatments have been developed, including several selective estrogen receptor modulators (SERMs), aromatase inhibitors (AIs) and, most recently, fulvestrant ('Faslodex'). Fulvestrant is an estrogen receptor (ER) antagonist, which, unlike the SERMs, has no known agonist (estrogenic) effect and downregulates the ER protein. Tamoxifen is effective and well tolerated, although the non-steroidal AIs, anastrozole and letrozole, are more effective treatments for advanced disease than tamoxifen. Fulvestrant has recently gained US Food and Drug Administration approval for the treatment of hormone receptor-positive metastatic breast cancer in postmenopausal women with disease progression following antiestrogen therapy. In two global phase III clinical trials fulvestrant was at least as effective and as equally well tolerated as anastrozole for the treatment of postmenopausal women with advanced and metastatic breast cancer. In a retrospective analysis of the combined data from these trials, mean duration of response was significantly greater for fulvestrant compared with anastrozole. These new hormonal treatments expand the choice of endocrine therapy for women with advanced breast cancer and offer new options for sequencing and combining treatments.read more

TL;DR: In this paper, the role of importin-4 in governing the nuclear transport of human epididymis protein 4 (HE4) was found to interact with estrogen receptor-a (ER-a).

Anastrozole alone or in combination with tamoxifen versus tamoxifen alone for adjuvant treatment of postmenopausal women with early breast cancer: first results of the ATAC randomised trial.
TL;DR: Anastrozole is an effective and well tolerated endocrine option for the treatment of postmenopausal patients with hormone-sensitive early breast cancer and longer follow-up is required before a final benefit:risk assessment can be made.

A potent specific pure antiestrogen with clinical potential.
TL;DR: The properties of ICI 182,780 identify this pure antiestrogen as a prime candidate with which to evaluate the potential therapeutic benefits of complete estrogen withdrawal in endocrine-responsive human breast cancer.

TL;DR: Risk of endometrial cancer increases following tamoxifen therapy for invasive breast cancer; however, net benefit greatly outweighs risk, and tamoxIFen treatment for breast cancer should continue.

TL;DR: Letrozole was significantly superior to tamoxifen in TTP, TTF, ORR, and clinical benefit rate, and its results support its use as first-line endocrine therapy in postmenopausal women with advanced breast cancer.
