The what, why and how of aromatase inhibitors: hormonal agents for treatment and prevention of breast cancer PMC

The activated receptors cause changes in the expression of specific genes, which can stimulate cell growth. Aromatase inhibitors are approved to reduce the risk of recurrence in postmenopausal women with estrogen receptor-positive breast cancer. They can also be used to treat advanced breast cancer, including stage 4 breast cancer, in which the malignancy has spread (metastasized) to other parts of the body. Among postmenopausal women with hormone receptor-positive breast cancer, aromatase inhibitors (alone or after tamoxifen) offer the same or slightly greater benefit compared to tamoxifen alone [90, ].

Completing aromatase inhibitor therapy

One early study compared outcomes for those who took the aromatase inhibitor letrozole after tamoxifen and people who didn’t. The study showed that taking letrozole reduced the risk of dying of breast cancer by 24% to 35%. Possible side effects of https://howtoarabic.com/peptide-sciences-introduces-sermorelin-2-mg-and/ include muscle pain, joint pain and menopausal symptoms (such as hot flashes). Many people who’ve had breast cancer take medications – tamoxifen or aromatase inhibitors – to help prevent the cancer from coming back. Doctors prescribe them for people with “hormone positive” tumors, which accounts for about 2 out of 3 breast cancers. Mouse studies were performed in compliance with an approved Institutional Animal Care and Use Committee protocol at the University of Chicago.

  • Women taking AIs are more likely to complain of symptoms related to estrogen deprivation.
  • Hormone therapy drug costs can quickly become a financial burden for you and your family.
  • Statins could be used along with AIs to improve both lipid profiles and endothelial function.
  • In women, aromatase inhibitors are only used in those who have gone through menopause.
  • No one should be forced to get less appropriate treatment because an insurer gives more coverage for IV and injectable drugs than for pills.

Side Effects

Your health care provider may prescribe drugs called bisphosphonates or the drug denosumab to help maintain bone density [10]. Although aromatase inhibitors can cause joint and muscle pain, they don’t cause permanent joint or muscle damage. Aromatase inhibitors are not without adverse effects, which primarily stem from profound estrogen depletion. Many women will turn to their internists for advice about whether to take these drugs, as well as help in preventing and managing adverse events. The purpose of this article is to provide primary care physicians with a basic understanding of AIs to help facilitate these interactions. “Procyanidin B dimers are a phytochemical that is found in the skin and seeds of grapes.

Bone-strengthening therapy

They are used to treat hormone receptor-positive early, locally advanced and metastatic breast cancers. They are called oestrogen receptor positive or ER positive (ER+) breast cancer. Around 80 out of every 100 breast cancers (around 80%) are oestrogen receptor positive.

Susan G. Komen® created the Komen Financial Assistance Program to help those struggling with the costs of breast cancer treatment by providing financial assistance to eligible individuals. Although the exact treatment for breast cancer varies from person to person, evidence-based guidelines help make sure high-quality care is given. These guidelines are based on the latest research and agreement among experts. Learn more about the importance of following your breast cancer treatment plan. Aromatase inhibitors don’t normally work in premenopausal women because their ovaries are still making estrogen. Women who take an aromatase inhibitor for more than 5 years continue to have side effects while taking the drug, including a higher number of bone fractures and a higher rate of osteoporosis [112, ].

As per use in the MIND model, animals had intact ovaries (having estradiol levels close to that of a postmenopausal woman). As a result of these trials, both tamoxifen and raloxifene have been approved by the FDA to reduce the risk of developing breast cancer in women at high risk of the disease. Tamoxifen is approved for this use regardless of menopausal status. Tests in a lab can show whether the cancer cells have receptors for estrogen or progesterone. If at least 1% of the cells have receptors, you can be considered for hormone therapy. These tests help your health care team understand how to treat your breast cancer.

Your doctor might recommend that you take it for another 5 years after this if there is a high risk of your cancer coming back. They will weigh up the benefit of taking the drug for longer with other factors, such as any side effects you have and whether you want to have children. Your doctor might change you to a different type of hormone treatment if your cancer starts growing again. You have check ups with your doctor during neo adjuvant hormone therapy to see if your cancer is getting smaller. If you are also having chemotherapy after surgery, you start hormone therapy once the chemotherapy finishes.

Aromatase inhibitors are most often used to treat existing breast cancers or to prevent previous breast cancers from recurring. Cancer medications given through an IV into a vein or by an injection (under the skin or into a muscle) are usually covered under a health insurance plan’s medical benefit. However, oral cancer drugs (cancer medications that are pills) are usually covered under a health insurance plan’s prescription drug benefit.
