Treatments that reduce androgen production by the testicles are the most commonly used hormone therapies for prostate cancer and the first type of hormone therapy that most men with prostate cancer receive. This form of hormone therapy (also called androgen deprivation therapy, or ADT) includes:
Can estrogens be used to treat prostate cancer?
Although estrogens are also able to inhibit androgen production by the testicles, they are seldom used today in the treatment of prostate cancer because of their side effects. Treatments that block the action of androgens in the body (also called antiandrogen therapies) are typically used when ADT stops working. Such treatments include:
Which antiandrogens are used in the treatment of prostate cancer?
Use of an antiandrogen drug in combination with orchiectomy or an LHRH agonist is called combined androgen blockade, complete androgen blockade, or total androgen blockade. Antiandrogens that are approved in the United States to treat prostate cancer include flutamide, enzalutamide, bicalutamide, and nilutamide.

Is hormone therapy for prostate cancer a form of chemotherapy?
Hormone therapy is a type of prostate cancer treatment that stops your body from making these hormones or letting them reach cancer cells. The cells then die or grow more slowly. It's also known as androgen deprivation therapy (ADT). You may get it on its own, but you'll likely also have chemotherapy.

What are the drugs that help prostate cancer grow?
Anti-androgens. For most prostate cancer cells to grow, androgens have to attach to a protein in the prostate cancer cell called an androgen receptor. Anti-androgens are drugs that also connect to these receptors, keeping the androgens from causing tumor growth.
What hormones are used to remove testicles?
Estrogens (female hormones) were once the main alternative to removing the testicles (orchiectomy) for men with advanced prostate cancer. Because of their possible side effects (including blood clots and breast enlargement), estrogens have been replaced by other types of hormone therapy.

What does CSPC mean in prostate cancer?
Castrate-sensitive prostate cancer (CSPC) means the cancer is being controlled by keeping the testosterone level as low as what would be expected if the testicles were removed (called the castrate level ).
Where is androgen made?
Most androgen is made by the testicles, but the adrenal glands (glands that sit above your kidneys) as well as the prostate cancer itself, can also make a fair amount. Lowering androgen levels or stopping them from getting into prostate cancer cells often makes prostate cancers shrink or grow more slowly for a time.
Can LHRH antagonists cause prostate cancer?
LHRH antagonists can be used to treat advanced prostate cancer. These drugs work in a slightly different way from the LHRH agonists, but they lower testosterone levels more quickly and don’t cause tumor flare like the LHRH agonists do. Treatment with these drugs can also be considered a form of medical castration.
Can prostate cancer cause pain in the spine?
Men whose cancer has spread to the bones may have bone pain. Men whose prostate gland has not been removed may have trouble urinating. If the cancer has spread to the spine, even a short-term increase in tumor growth as a result of the flare could press on the spinal cord and cause pain or paralysis.
What hormones are used to treat prostate cancer?

What is the effect of luteinizing hormone releasing hormone?
Certain medications — known as luteinizing hormone-releasing hormone (LHRH) or gonadotropin-releasing hormone (GnRH) agonists and antagonists — prevent your body's cells from receiving messages to make testosterone. As a result, your testicles stop producing testosterone. Medications that block testosterone from reaching cancer cells.
What happens after prostate cancer treatment?

Hormone therapy can be used: In advanced (metastatic) prostate cancer to shrink the cancer and slow the growth of tumors, which also might relieve signs and symptoms.
Can hormone therapy be adjusted?
Depending on your circumstances, you may undergo tests to monitor your medical situation and watch for cancer recurrence or progression while you're taking hormone therapy. Results of these tests can give your doctor an idea of how you're responding to hormone therapy, and your therapy may be adjusted accordingly.
Does testosterone help prostate cancer?
Most prostate cancer cells rely on testosterone to help them grow. Hormone therapy causes prostate cancer cells to die or to grow more slowly. Hormone therapy for prostate cancer may involve medications or possibly surgery to remove the testicles. Hormone therapy for prostate cancer is also known as androgen deprivation therapy.
How much testosterone is produced in prostate cancer?
There are several different types of hormone therapy for prostate cancer: Orchiectomy: About 90% of testosterone is produced by the testicles. So orchiectomy—the surgical removal of the testicles—is an effective way to drastically reduce testosterone release. This approach has been used successfully since the 1940s.
What is LHRH agonist?
LHRH Agonist: LHRH, or luteinizing-hormone releasing hormone, is a hormone released by the body that initiates the production of testosterone (GnRH , or gonadotropin-releasing hormone). Blocking the release of LHRH through the use of agonists (substances that initiate a response) is one of the most common hormone therapies used in men ...
What does LHRH do to your body?
LHRH agonists cause a “testosterone flare” reaction, which is an initial transient rise in testosterone that happens over the first week or two after first treatment . This can result in a variety of symptoms, ranging from bone pain to urinary frequency or difficulty.
Can anti-androgen block testosterone?
Fortunately, this can be prevented by prescribing an anti-androgen, a drug that blocks the testosterone’s effects. LHRH Antagonists: These are a newer class of medications that can block LHRH (GnRH) from stimulating testosterone production without causing an initial testosterone surge.
Can LHRH agonists cause hot flashes?
When used in combination with LHRH agonists, anti-androgens tend to increase the risk of hot flashes, and in rare occasions can result in liver injury. Your liver function should be monitored while you take these medications. Fortunately, gynecomastia is rare when LHRH agonists and anti-androgens are used together.
When It's Used
Hormone therapy is a common treatment for all stages of prostate cancer. You might get it along with other treatments like radiation and chemotherapy.
