What is the main goal of hormone treatment in prostate cancer?
Hormone therapy is also called androgen suppression therapy. The goal is to reduce levels of male hormones, called androgens, in the body, or to stop them from fueling prostate cancer cells. Androgens stimulate prostate cancer cells to grow. The main androgens in the body are testosterone and dihydrotestosterone (DHT).Sep 23, 2021
What hormones are used in the treatment of prostate cancer?

What hormone controls the prostate?
Testosterone is a hormone that controls how the prostate grows and develops. It also controls other male characteristics, such as muscle strength, erections, and the size and function of the penis and testicles.
What are the two most common hormones used for prostate cancer?
Blocking the release of LHRH with the use of LHRH therapies is the most common hormone therapy used on prostate cancer patients. Drugs in this class include Lupron, Viadur, Zoladex, Trelstar and Eligard. They are administered as regular shots ranging from once per month to once per year.
How does hormone therapy work for cancer?
Hormone therapy for cancer uses medicines to block or lower the amount of hormones in the body to stop or slow down the growth of cancer. Hormone therapy stops hormones being made or prevents hormones from making cancer cells grow and divide. It does not work for all cancers.
What is hormone therapy used for?

How is hormone therapy given?
Hormone therapy can be given in a few ways: Oral medication – Taken by mouth. Injection – Given by an injection under the skin (subcutaneous) or in the muscle (intramuscular). Surgical intervention – Removal of the ovaries in women, or testicles in men, causes lower levels of hormones being made.Apr 7, 2022
Why is hormone therapy recommended?
Hormone therapy is a type of cancer treatment that removes, blocks, or adds specific hormones to the body. It is also called hormonal therapy or endocrine therapy. A main reason that hormone therapy may be recommended is because some types of cancer use the body's natural hormones to fuel their growth.
How long does it take hormone therapy to work?
It may take a few weeks to feel the effects of treatment and there may be some side effects at first. A GP will usually recommend trying treatment for 3 months to see if it helps. If it does not, they may suggest changing your dose, or changing the type of HRT you're taking.
How Long Does hormone treatment work for prostate cancer?
On average, hormone therapy can stop the advance of cancer for two to three years. However, it varies from case to case. Some men do well on hormone therapy for much longer.
When does hormone therapy stop working for prostate cancer?
On average, hormone therapy can stop cancer progression for 1-2 years before the prostate cancer becomes resistant. Hormone therapy can stop working over time as the prostate cancer begins to grow again (called castrate-resistant prostate cancer).Jun 9, 2021
What is the success rate of hormone therapy?
Hormone replacement therapy users had a 100% survival rate at 6 years as opposed to 87% in nonusers. Both groups of tumors were detected by screening mammography, thus detected "early" by current convention. Yet, we observed a survival benefit for those women who had received HRT.
How do androgens help prostate cells grow?
Androgens promote the growth of both normal and cancerous prostate cells by binding to and activating the androgen receptor, a protein that is expressed in prostate cells ( 1 ). Once activated, the androgen receptor stimulates the expression of specific genes that cause prostate cells to grow ( 2 ).
What does it mean when your PSA is high?
An increase in PSA level may indicate that a man’s cancer has started growing again. A PSA level that continues to increase while hormone therapy is successfully keeping androgen levels extremely low is an indicator that a man’s prostate cancer has become resistant to the hormone therapy that is currently being used.
What hormones are released when androgen levels are low?
Normally, when androgen levels in the body are low, the hypothalamus releases LHRH. This stimulates the pituitary gland to produce luteinizing hormone, which in turn stimulates the testicles to produce androgens. LHRH agonists, like the body’s own LHRH, initially stimulate the production of luteinizing hormone.
What is the most common treatment for prostate cancer?
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:
What hormones block androgen production?
block androgen production (synthesis) throughout the body. Androgen production in men. Drawing shows that testosterone production is regulated by luteinizing hormone (LH) and luteinizing hormone-releasing hormone (L HRH). The hypothalamus releases LHRH, which stimulates the release of LH from the pituitary gland.
What does LHRH do to the testicles?
LHRH agonists, like the body’s own LHRH, initially stimulate the production of luteinizing hormone. However, the continued presence of high levels of LHRH agonists actually causes the pituitary gland to stop producing luteinizing hormone. As a result, the testicles are not stimulated to produce androgens.
What is the procedure to remove testicles?
This form of hormone therapy (also called androgen deprivation therapy, or ADT) includes: Orchiectomy, a surgical procedure to remove one or both testicles. Removal of the testicles, called surgical castration , can reduce the level of testosterone in the blood by 90% to 95% ( 5 ).
What is BHP in prostate surgery?
A patient with benign prostatic hyperplasia (BHP) is being considered for a transurethral resection of the prostate (TURP). What complications can occur as a result of this procedure? Select all that apply.
How long does it take for a prostate resection to clot?
Twelve hours after the patient has a transurethral resection of the prostate, he begins having bright red urinary drainage with numerous clots. The nurse, per the surgeon's orders, irrigates the catheter with normal saline, but the bleeding and clots continue.
What does CRPC mean?
Castrate-resistant prostate cancer (CRPC) means the cancer is still growing even when the testosterone levels are at or below the castrate level. Some of these cancers might still be helped by other forms of hormone therapy, such as abiraterone or one of the newer anti-androgens.
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 is the goal of hormone therapy?
The goal is to reduce levels of male hormones, called androgens, in the body, or to stop them from fueling prostate cancer cells. Androgens stimulate prostate cancer cells to grow. The main androgens in the body are testosterone ...
What is the effect of orchiectomy?
Orchiectomy (surgical castration) Even though this is a type of surgery, its main effect is as a form of hormone therapy. In this operation, the surgeon removes the testicles, where most of the androgens (such as testosterone and DHT) are made. This causes most prostate cancers to stop growing or shrink for a time.
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 ).
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.
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.

Credit: iStock. Hormone therapy is a cancer treatment that slows or stops the growth of cancer that uses hormones to grow. Hormone therapy is also called hormonal therapy, hormone treatment, or endocrine therapy.
Why does hormone therapy cause side effects?
Because hormone therapy blocks your body’s ability to produce hormones or interferes with how hormones behave, it can cause unwanted side effects. The side effects you have will depend on the type of hormone therapy you receive and how your body responds to it. People respond differently to the same treatment, so not everyone gets the same side effects. Some side effects also differ if you are a man or a woman.
What is the best treatment for cancer?
Hormone therapy is most often used along with other cancer treatments. The types of treatment that you need depend on the type of cancer, if it has spread and how far, if it uses hormones to grow, and if you have other health problems.
