It was previously used in the treatment of breast cancer, but has been replaced by more effective and less toxic agents. Estrace is an estrogen which was also formerly used for antiandrogen therapy of prostate cancer. [2] Polyestradiol phosphate is a long-acting derivative of estradiol that is applied as an intramuscular injection.
Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
Estrogen deprivation therapy, also known as endocrine therapy, is a form of hormone therapy that is used in the treatment of breast cancer.Modalities include antiestrogens or estrogen blockers such as selective estrogen receptor modulators (SERMs) like tamoxifen, selective estrogen receptor degraders like fulvestrant, and aromatase inhibitors like anastrozole and ovariectomy.
Aldosterone is the main mineralocorticoid steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. [ 4 ] [ 5 ] It is essential for sodium conservation in the kidney, salivary glands, sweat glands, and colon. [ 6 ]
It is used as endocrine therapy for women with estrogen or progesterone receptor-positive, stage 4 or recurrent metastatic breast cancer [9] and has demonstrated similar efficacy compared to tamoxifen as adjuvant treatment of breast cancer and in the treatment of metastatic breast cancer. [8]
Moreover, breast cancer risk is heightened following use of the combined oral contraceptive pill and combined hormone replacement therapy. [4] Armed with this evidence that endogenous and exogenous changes in estrogen and progesterone levels modulate the risk of breast cancer, it is apparent that hormones can play a key role in breast cancer.
A gonadotropin-releasing hormone agonist (GnRH agonist) is a type of medication which affects gonadotropins and sex hormones. [1] They are used for a variety of indications including in fertility medicine and to lower sex hormone levels in the treatment of hormone-sensitive cancers such as prostate cancer and breast cancer, certain gynecological disorders like heavy periods and endometriosis ...
Androsterone, or 3α-hydroxy-5α-androstan-17-one, is an endogenous steroid hormone, neurosteroid, and putative pheromone. [1] It is a weak androgen with a potency that is approximately 1/7 that of testosterone. [2] Androsterone is a metabolite of testosterone and dihydrotestosterone (DHT).
