What are the two things that are needed for prostate cancer?
Androgens are also necessary for prostate cancers to 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 ...
What is the LHRH agonist?
LHRH agonists are given by injection or are implanted under the skin. Four LHRH agonists are approved to treat prostate cancer in the United States: leuprolide (Lupron), goserelin (Zoladex), triptorelin (Trelstar), and histrelin (Vantas).
What are the hormones that control the development and maintenance of male characteristics?

Androgens (male sex hormones) are a class of hormones that control the development and maintenance of male characteristics. The most abundant androgens in men are testosterone ...
Where are androgens produced?
Most of the remaining androgens are produced by the adrenal glands . Androgens are taken up by prostate cells, where they either bind to the androgen receptor directly or are converted to dihydrotestosterone (DHT), which has a greater binding affinity for the androgen receptor than testosterone.
Which hormone is responsible for the production of testosterone?
Drawing shows that testosterone production is regulated by luteinizing hormone (LH) and luteinizing hormone-releasing hormone (LHRH). The hypothalamus releases LHRH, which stimulates the release of LH from the pituitary gland. LH acts on specific cells in the testes to produce the majority of testosterone in the body.

What Is Advanced Prostate Cancer
When prostate cancer spreads beyond the prostate or returns after treatment, it is often called advanced prostate cancer.
Biochemical Recurrence And Hormone Therapy
Hormone therapy is the standard of care for patients with metastatic prostate cancer, but for patients whose only sign of cancer recurrence is a rising PSA level , the benefits are less clear.
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 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.
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.

Overview of Hormone Therapy for Prostate Cancer
Testosterone, an androgen, fuels the growth of prostate cancer cells. Testosterone is produced primarily in the testicles. Smaller amounts are also produced in the adrenal glands. Once you have prostate cancer, prostate cancer cells may themselves produce testosterone, fueling the disease.
Reducing Testicular Androgen Levels
Testosterone production can be reduced or halted in the testes with medication or surgery. There are several types of treatment. 2
Reducing Adrenal Gland Androgen Levels
The adrenal glands and prostate cancer tumors produce testosterone, although in lesser amounts than the testes. Medications that block or prohibit androgen production outside of the testes may be given in addition to other forms of hormonal therapy. They include:
Drugs That Stop Androgens From Functioning
There are several classes of medication that block the effects of androgens, including testosterone. They include:
Treatment Issues With Hormone Therapy for Prostate Cancer
Hormone therapy is not a cure-all for treating prostate cancer. Side effects can be life-altering as well as physically and emotionally draining.
Summary
Prostate cancer cells grow in response to testosterone. Hormone therapy may be done to reduce the amount of testosterone produced in the testicles. It may also be done to lower the amount of testosterone made in the adrenal glands.
A Word From Verywell

In the long-run, an orchiectomy is much cheaper than LHRH agonists.". Hormone therapy for prostate cancer can cause bone thinning osteoporosis, which can lead to broken bones. However, treatment with bisphosphonates -- like Aredia, Fosamax, and Zometa -- may help prevent this condition from developing, says Holden.
Can LHRH cause cancer?
In some cases, starting treatment with an LHRH agonist can cause a "tumor flare," a temporary acceleration of the cancer's growth due to an initial increase in testosterone before the levels drop. This may cause the prostate gland to enlarge, obstructing the bladder and making it difficult to urinate.
What is the best treatment for prostate cancer?
Androgen-deprivation therapy , more commonly known as hormone therapy, is one of the most powerful weapons in the fight against prostate cancer because it significantly reduces the fuel supply that is feeding malignant growth.
What is the role of androgens in prostate cancer?
Androgens, the family of male sex hormones that includes testosterone, function as a fuel for growth — a quality that explains their central role in both normal development and prostate cancer.
How much testosterone is needed for prostate cancer?
For men, normal testosterone levels range from 300 to 1,000 ng/dl. The FDA requires that any new drug used in hormone therapy for prostate cancer lower testosterone levels to 50 ng/dl or less. In my practice, I usually try to lower levels even further, to 20 ng/dl.
How many men have prostate cancer?
An analysis of 98 men with prostate cancer that had spread to the lymph nodes, who were randomly assigned to receive immediate hormone therapy or to forgo it until the disease spread further to bones or lungs, found that early treatment saved lives.
Where do LHRH agonists work?
LHRH agonists are among the most popular choices for hormone therapy in prostate cancer. These drugs work centrally, on the brain.
Where do prostate cancer cells migrate?
If prostate cancer cells escape the prostate, they migrate first to surrounding structures, such as the seminal vesicles and lymph nodes, and later to the bones or, rarely, to other soft tissues. Hormone therapy is recommended as a palliative treatment, to relieve symptoms such as bone pain.
Where are androgens produced?
Most androgens are produced in the testicles. Androgens fuel the growth of prostate cells, including prostate cancer cells. Hormone therapy — also known as androgen-deprivation therapy — seeks to cut off the fuel supply. But different therapies work in different ways.
