Aromatase inhibitors in men: effects and therapeutic options Reproductive Biology and Endocrinology Full Text

In 2021, Ceccato and colleagues described four male patients with cabergoline-resistant prolactinoma who were treated with anastrozole (1 mg daily) combined with the maximum tolerated dose of cabergoline. This combination resulted in a decline in prolactin levels and decreased tumor sizes in all patients. At 1 year, the mean decline in prolactin secretion was 70% (ranging from −44% to −97%), and one patient achieved normal prolactin levels. The mean tumor volume shrinkage was 47% (ranging from −25% to −69%) [21]. These case reports illustrate the important contribution of estrogens to male health and identify the possible indications and risks of aromatase-inhibitor treatment in men.

• Tamoxifen was much more effective, however, in the prevention of gynecomastia in these men [69,70].
• Patients should also have a baseline bone mineral density test (DEXA scan) before initiating the treatment 6, 7.
• It can also be used to treat cancer that has spread, or cancer that has come back after treatment (recurred).
• In some cases, prolactinomas do not cause any noticeable signs or symptoms.

Exposure to hormones

This combination treatment effectively increased growth velocity but epiphysial maturation was slower in the letrozole-treated group, leading to a significant increase in predicted adult height [64, 65]. This combination treatment effectively increased growth velocity but epiphysial maturation was slower in the letrozole-treated group, leading to a significant increase in predicted adult height [64,65]. Moreover, aromatase inhibitors can be used in premenopausal women if they are given together with a drug that suppresses ovarian function. Because the ovaries are the main source of estrogen in premenopausal women, estrogen levels in these women can be reduced by eliminating or suppressing ovarian function. Ovarian ablation can be done surgically in an operation to remove the ovaries called oophorectomy or by treatment with radiation. Alternatively, ovarian function can be suppressed temporarily by treatment with drugs called gonadotropin-releasing hormone (GnRH) agonists, which are also known as luteinizing hormone-releasing hormone (LHRH) agonists.

The most common side effects of aromatase inhibitors are symptoms of menopause, such as hot flashes, night sweats, and vaginal dryness. This side effect can be serious enough to cause some women to stop taking the drugs. Hormone therapy following surgery, radiation or chemotherapy has been shown to reduce the risk of 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. Cabergoline, an ergot derivative with a high affinity for lactotroph buy steroids tablets dopamine 2 receptors, is a long-acting dopamine agonist, usually administered once or twice weekly.

Based on the strength of the available evidence, treatment options may be described as either “standard” or “under clinical evaluation.” These classifications should not be used as a basis for insurance reimbursement determinations. More information on insurance coverage is available on Cancer.gov on the Managing Cancer Care page. Tumor size, lymph node involvement, and grade are anatomical prognostic factors, while estrogen receptor, progesterone receptor, and HER2 status are predictive of response to therapy. Male breast cancer is rare.[2] Fewer than 1% of all breast carcinomas occur inmen.[3,4] The mean age at diagnosis is between 60 and 70 years; however, men of allages can be affected by the disease.

Aromatase is the enzyme that catalyzes a key aromatization step in the synthesis of estrogen. It converts the enone ring of androgen precursors such as testosterone, to a phenol, completing the synthesis of estrogen. Because hormone-positive breast and ovarian cancers are dependent on estrogen for growth, AIs are taken to either block the production of estrogen or block the action of estrogen on receptors.

Should I Take Aromatase Inhibitors for Breast Cancer?

The most common side effects of AIs are symptoms of menopause, such as hot flashes, night sweats, and vaginal dryness. Generic drugs cost less than name brand drugs but are just as effective. You may qualify for programs that help with drug costs or offer low-cost or free prescriptions. Hormone therapy drug costs can quickly become a financial burden for you and your family. Talk with your health care team about which treatment guidelines they follow.

• The free Drugs.com Discount Card works like a coupon and can save you up to 80% or more off the cost of prescription medicines, over-the-counter drugs and pet prescriptions.
• Share your concerns about affording medications with your prescriber.
• Decisions about the type and duration of adjuvant hormone therapy are complicated and must be made on an individual basis in consultation with an oncologist.
• As a result, people often find themselves facing high out-of-pocket costs when filling prescriptions for oral cancer drugs.

“I always advise patients to talk with their oncologist before starting any new supplements or herbs — especially since grape seed extract can increase the risk of bleeding,” adds Proctor. Aromatase inhibitors are typically used to treat people who have already experienced menopause. If this was helpful, donate to help fund patient support services, research, and cancer content updates. Learn about ways to manage hot flashes and other menopausal symptoms. You’ll get a baseline measure of your bone density so changes in your bone density can be monitored.

Your donation can make a difference in the future of healthcare. If you already have heart disease, discuss all the potential benefits and risks with a doctor. Armidex, Aromasin, and Femara can cause fetal harm and should not be used if there is any chance of pregnancy. As a safeguard, pregnancy testing is recommended seven days prior to the start of treatment if a woman’s menopausal status is unknown. Advise your oncologist about any medications you are taking, whether they are pharmaceutical, over-the-counter, recreational, or traditional to avoid drug interactions.

Similarly, bisphosphonate drugs like Zometa (zoledronic acid) may help counteract osteopenia, though they increase the risk of osteonecrosis of the jaw. The long-term effects of aromatase inhibitors are arguably more concerning. Unlike tamoxifen, aromatase inhibitors tend to speed up osteopenia (bone loss) in older women who are already at risk of bone problems. As with any medication, aromatase inhibitors can cause side effects and adverse reactions.

Your oncologist will ask about any side effects you’re experiencing. One approach to hormone therapy is to stop the hormones from attaching to the receptors on the cancer cells. When the hormones can’t access the cancer cells, the cancer’s growth may slow and the cells may die. For example, a doctor might prescribe this therapy for someone who hasn’t yet undergone menopause and is taking medication to reduce the functions of the ovaries, including estrogen production. The costs of these medications can vary considerably based on your insurance coverage.

That may be why weight gain is such a key risk factor for breast cancer after menopause. The female hormone estrogen is “fuel” for about http://smac-bd.com/2024/05/29/how-steroids-can-help-bodybuilders-improve-their-10/ 80% of breast cancers in women who’ve gone through menopause. 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. They only lower estrogen levels in women whose ovaries aren’t making estrogen (such as women who have already gone through menopause).

In premenopausal women, aromatase inhibitors induce an increase in gonadotropin secretion secondary to the reduced negative feedback of estrogen to the pituitary, resulting in ovarian stimulation. Clinicians can use aromatase inhibitors to induce ovulation in the treatment of infertility 6, 13. Aromatase activity increases in endometriosis with extrauterine endometrial tissue acting as a source of estrogens. Estrogen stimulates the synthesis of prostaglandin E2 (PGE2), which causes increased aromatase activity in the endometrium. This vicious cycle leads to the growth of ectopic endometrial tissue, which is blocked by aromatase inhibitors by inhibiting the synthesis of estrogen in extrauterine endometrial tissue 14, 15.
