Hormone therapy is also called androgen deprivation therapy (ADT) or androgen suppression therapy. The goal is to reduce levels of male hormones, called androgens, in the body, or to stop them from affecting prostate cancer cells. Androgens stimulate prostate cancer cells to grow.

Hormone therapy works by either stopping your body from making testosterone, or by stopping testosterone from reaching the cancer cells. Prostate cancer cells usually need testosterone to grow. Testosterone is a hormone that controls how the prostate grows and develops.

Orchiectomy (surgical castration) Even though this is a type of surgery, its main effect is as a form of hormone therapy.

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.

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.

Androgen receptors in prostate cells

Each cell in our body has an outer membrane that holds the cell’s contents. When circulating androgens come into contact with a prostate cell, they cross through the membrane into the cell where they bind with ARs. Once it is bound with an androgen, it is activated to enter the cell’s nucleus that contains your DNA. The bound AR now binds with DNA.

Androgen receptors and prostate cancer

Just as healthy prostate cells depend on androgens and the action of their ARs, so do prostate cancer cells.

Depriving prostate cancer of androgens and the action of ARs

How do you deprive a man of his male hormones? In 1941, Charles Huggins published a paper showing that for patients with painful metastatic PCa, lowering their testosterone levels either by castration (surgical removal of testes) or injecting female hormones (estrogens) brought relief.

Hormone therapy side effects

Because ADT shuts down androgen production and the AR effect on gene expression, male characteristics are affected.

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.

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 the study was performed

During the study, scientists randomized 1,071 men with intermediate- or high-risk localized prostate cancer into four groups. One group received radiation and six months of an anti-testosterone drug called leuporelin, and the second group received radiation plus 18 months of leuporelin therapy.
