Your doctor checks your cancer cells for these receptors when you are diagnosed. Aromatase inhibitors also keep ER-positive breast cancer from recurring, or coming back, after breast cancer surgery. If you have an increased risk of developing ER-positive breast cancer, taking an aromatase inhibitor may reduce your risk.
The androgenic structure of type I steroidal AIs may give rise to hormonal effects apart from the decrease in estrogen production caused by inhibition of aromatase. The androgenic properties of exemestane make it distinct from the nonsteroidal AIs letrozole and anastrozole. The principal metabolite of exemestane, 17-hydroexemestane (17β-hydroxy-6-methylenandrosta-1,4-diene-3,17-dione), binds with high affinity to the androgen receptor (AR) (Table 1) [6, 30, 31]. When exemestane is given to postmenopausal women at the approved dose of 25 mg daily, the circulating levels of 17-hydroexemestane are approximately 15% that of unchanged exemestane [32]. Anastrozole is a medication used in the management and treatment of breast cancer.
Treatment with aromatase inhibitors can be started at the same time with radiation therapy. Hormone therapy works by either lowering the amount of hormones in the body or by blocking them from getting to breast cancer cells. Like tamoxifen, these drugs are more often used to treat hormone receptor-positive breast cancer than to lower breast cancer risk. Aromatase inhibitors are medicines that reduce the amount of estrogen in the body. This medicine deprives breast cancer cells of the hormones they need to grow. Studies have found that exemestane and anastrozole may reduce the risk of breast cancer in women who have already gone through menopause and may be at high risk of breast cancer.
Because of this, doctors often recommend checking bone density before starting one of these drugs. A 2015 study in the New England Journal of Medicine reported that the use of Aromasin in women on ovary suppression therapy was just as effective in preventing recurrence after five years as tamoxifen. After five years of use, an estimated one of out of every 10 women on aromatase inhibitors will experience a fracture due to drug-induced osteoporosis.
Aromatase inhibitors don’t stop the ovaries from making estrogen. If your ovaries are still functioning, aromatase inhibitors will have no effect. Ovarian ablation can be done surgically in an operation to remove the ovaries (called oophorectomy) or by treatment with radiation. All the treatments that stop your ovaries working give you an early menopause, but this might be temporary with goserelin. You are likely to have menopausal symptoms that start very suddenly. LHRH drugs work by blocking a hormone made in the pituitary gland that stimulates your ovaries to make and release oestrogen.
You’ll get a baseline measure of your bone density so changes in your bone density can be monitored. Interestingly, corresponding data on the crossresistance of AI classes in experimental systems are lacking. However, a recent study using MCF-7aro cells made resistant to AIs indicates that differential patterns of gene expression are found according to different AIs, again suggesting that mechanisms of resistance are different [60, 61].
Aromatase inhibitors are a class of medicines that work by blocking the enzyme aromatase, the enzyme that converts androgens into estrogen. Aromatase inhibitors are used in the treatment of breast cancer to reduce levels of circulating estrogen. This means that less estrogen is available to stimulate the growth of estrogen receptor (ER) positive breast cancer cells, slowing or inhibiting the progression of these cancers. Hormone therapy following surgery, radiation or chemotherapy has been shown to reduce the risk of https://authorbecca.com/the-ultimate-guide-to-drostanolone-enanthate-2/ breast cancer recurrence in people with early-stage hormone-sensitive breast cancers. It also can effectively reduce the risk of metastatic breast cancer growth and progression in people with hormone-sensitive cancers. Most breast cancers are ER positive, and clinical trials have tested whether hormone therapy can be used to prevent breast cancer in women who are at increased risk of developing the disease.
They provided assistance in researching and ordering reference articles and rationalizing authors’ input into an initial manuscript draft, including development of the EndNote library and copyediting. Our team is made up of doctors and oncology certified nurses with deep knowledge of cancer care as well as editors and translators with extensive experience in medical writing.

All three aromatase inhibitors work the same way and reduce the production of estrogen in the body. If your cancer has spread to other parts of your body, hormone therapy for breast cancer may help control it. Aromatase inhibitors bind to aromatase and stop the process of conversion to estrogen. This keeps estrogen levels down and helps prevent cancer cells from getting the estrogen they can use to grow and spread. A 2018 study in the Journal of Clinical Oncology also noted that the risk of diabetes was 240% greater in women on aromatase inhibitors than in the general population. Although the risk was far lower with tamoxifen, aromatase inhibitors do not pose the risk of thromboembolism (blood clots) or endometrial cancer that tamoxifen does.
