How do I choose the right doctor for 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.
Which medications are used to treat prostate cancer?

How does LHRH affect prostate cancer?
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. A flare can be avoided by giving drugs called anti-androgens (discussed below) for a few weeks when starting treatment with LHRH agonists.
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?

What is castrate resistant?
Castrate-resistant (cancer that is still growing despite low testosterone levels from an LHRH agonist, LHRH antagonist, or orchiectomy)
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 is apalutamide used for?
Apalutamide can also be used for metastatic castrate-sensitive prostate cancer.
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 Because of their possible side effects (including blood clots and breast enlargement), estrogens have been replaced by other types of hormone therapy.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 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 is the risk of prostate cancer recurrence?
Early-stage prostate cancer with an intermediate or high risk of recurrence. Men with early-stage prostate cancer that has an intermediate or high risk of recurrence often receive hormone therapy before, during, and/or after radiation therapy, or after prostatectomy (surgery to remove the prostate gland) ( 7 ). Factors that are used to determine the risk of prostate cancer recurrence include the grade of the tumor (as measured by the Gleason score ), the extent to which the tumor has spread into surrounding tissue, and whether tumor cells are found in nearby lymph nodes during surgery.
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 hormones inhibit prostate cancer?
Early in their development, prostate cancers need androgens to grow. Hormone therapies, which are treatments that decrease androgen levels or block androgen action, can inhibit the growth of such prostate cancers, which are therefore called castration sensitive, androgen dependent, or androgen sensitive.
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 the flare of LHRH?
When patients receive an LHRH agonist for the first time, they may experience a phenomenon called " testosterone flare ." This temporary increase in testosterone level occurs because LHRH agonists briefly cause the pituitary gland to secrete extra luteinizing hormone before blocking its release. The flare may worsen clinical symptoms (such as bone pain, ureter or bladder outlet obstruction, and spinal cord compression ). The increase in testosterone is usually countered by giving another type of hormone therapy, called antiandrogen therapy, along with the LHRH agonist for the first few weeks of treatment.
What medications stop the body from producing testosterone?
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.
What is the best way to block testosterone from cancer cells?
Anti-androgens block testosterone from reaching cancer cells. These oral medications are usually prescribed along with an LHRH agonist or before taking an LHRH agonist.
What is the medication that blocks testosterone from reaching cancer cells?
Medications that block testosterone from reaching cancer cells. These medications, known as anti-androgens, usually are given in conjunction with LHRH agonists. That's because LHRH agonists can cause a temporary increase in testosterone before testosterone levels decrease.

How does an orchiectomy work?
Orchiectomy, DES, LHRH agonists, and the GnRH antagonist all work by shutting down production of testosterone in the testes. But about 5% to 10% of male hormones are produced in the adrenal glands. These androgens, which are closely related to testosterone, can also be converted to DHT and promote prostate cancer growth.
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.

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.
Can prostate cancer be treated with androgen?
We don’t know yet why men with prostate cancer develop androgen resistance, but a leading theory is that prostate tumors contain different types of cells, some of which are resistant to hormone treatment. Eventually, these resistant prostate cancer cells multiply and the disease advances. But even if it doesn’t cure prostate cancer, hormone therapy can keep it at bay for years. In fact, one of my patients has now been on some type of hormone therapy for nearly 16 years.
