What should PSA be during hormone therapy?
Recent studies have shown that for optimal results, PSA levels should be lower than 1 ng/ml, and even lower than 0.5 ng/ml. Levels that are above 1 or 2 ng/ml 12 to 18 months following completion of radiation treatments are very worrisome, because they indicate that the cancer may not have been eradicated.Mar 31, 2009

What is the receptor that helps prostate cancer cells grow?
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. Anti-androgens are also sometimes called androgen receptor antagonists.
What are the main androgens in the body?
The main androgens in the body are testosterone and dihydrotestosterone (DHT). 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.
Is prostate cancer permanent?
It is probably the least expensive and simplest form of hormone therapy. But unlike some of the other treatments, it is permanent, and many men have trouble accepting the remo val of their testicles.
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.
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.
Does hormone therapy affect memory?
Still, hormone therapy does seem to lead to memory problems in some men. These problems are rarely severe, and most often affect only some types of memory.
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.
