What are the best treatment options for prostate cancer?
Hormone therapy (also called androgen deprivation therapy or ADT) is part of the standard of care for advanced and metastatic prostate cancer. ADT is designed to either stop testosterone from being produced or to directly block it from acting on prostate cancer cells.
What radiation is best for prostate cancer?
Androgen deprivation therapy (ADT) Prostate cancer needs testosterone to grow. Reducing how much testosterone your body makes may slow the cancer’s growth or shrink the cancer temporarily. Testosterone is an androgen (male sex hormone), so this treatment is called androgen deprivation therapy (ADT). It is also known as hormone therapy.
What is the success rate for prostate cancer treatments?

How long does ADT work for prostate cancer?
In localized and locally advanced prostate cancer, ADT is typically combined with radiotherapy (RT) to the prostate area. Patients typically receive ADT for two to three years, based on previous clinical trials that established that long-term ADT (28-36 months) is more effective than short term ADT (4-6 months).Mar 14, 2018

Does ADT lower PSA?
The presence of distant metastases at the initiation of ADT, a higher PSA nadir after ADT, a higher velocity of PSA decline, and a time to reach PSA nadir of <9 months are associated with an increased risk of progression to CRPC.
Does ADT shrink prostate?
ADT controls cancer cells by reducing the levels of androgens in the body. This suppression has a direct effect on cancer cells themselves. It also affects new blood vessels that the cancer cells develop to support their growth. ADT is used increasingly to shrink prostate tumours before radiotherapy.
How long does it take for ADT to wear off?

Where is brachytherapy done?

The device may be a tube or cylinder made to fit the specific body opening.Jun 19, 2020
How quickly does PSA drop after hormone therapy?
Median PSA at the end of hormonal therapy for all patients was 0.2 ng/mL (range: 0 - 96.2). A total of 744 patients (70%) reached a PSA-CR at the end of hormonal therapy. The time to reach PSA nadir was 3.7 months, ranging from 0.8 to 8.2 months. With a median follow-up of 7.2 years, higher rates of BF (56% vs.
How long do you have hormone treatment before radiotherapy?
You might have hormone therapy before, during and after radiotherapy. Doctors usually recommend that you have the treatment for between 3 months and 3 years. How long depends on the risk of your cancer coming back and how many side effects you get.
What is ADT therapy?
ADT: What You Really Need to Know. The only people who really like androgen deprivation therapy (also called ADT, or hormonal therapy) are the drug companies that make billions of dollars a year selling the drugs. Doctors don’t like it, and men don’t like being on these drugs. So why do it?
What is provenge in cancer?
Immunotherapy; a vaccine such as Provenge, designed to boost your body’s ability to fight off the cancer. Early chemotherapy. A clinical trial testing a promising new drug. Don’t get us wrong; we’re not hating on ADT. If you need it, you need it. But it’s not just like taking a vitamin supplement or getting a flu shot.
How to get mad at yourself?
You will need to get mad at it. Work hard to take back your life – work doubly hard, because not only will it try to turn you into a tub of butter, but you might get mildly depressed. Your brain will tell you that you’re too tired to exercise. It’s deceiving you. You must not listen to it. Exercise anyway.

Does ADT cause cognitive impairment?

ADT has a lot of side effects, including a higher risk of cognitive impairment, but the biggest elephant in the room is the fact that men on ADT lose their sex drive and ability to have an erection.

What is the role of androgen receptors in prostate?
Prostate cells contain an Androgen Receptor (AR), that when stimulated by androgens like testosterone, promotes growth and maintains prostatic differentiation.
What is the difference between LHRH and LHRH?
The LHRH agonists produce a sudden increase on levels of testosterone followed by a huge falling, process called flare, whereas LHRH antagonists decrease directly the amount of testosterone. LHRH agonists and antagonists used in androgen deprivation therapy include leuprorelin, goserelin, triptorelin, histrelin, buserelin, and degarelix.
What is the process of synthesis of testosterone?
Chemical castration. The synthesis of testosterone is mediated by a chain of processes that start in the brain. When the body detects a low level of testosterone, the hypothalamus starts to produce LHRH. LHRH activates the synthesis of LH (Luteinizing hormone) within the pituitary gland.
How does LH work?
They work by inhibiting the formation of LH in the pituitary gland.
Does ADT affect testosterone levels?
One study suggests that ADT can alter the hormonal balance necessary for male sexual activity. As men age, testosterone levels decrease by about 1% a year after age 30; however, it is important to determine whether low testosterone is due to normal aging, or to a disease, such as hypogonadism.
Does testosterone affect sexual function?
Testosterone plays a significant role in sexual functioning; therefore, naturally declining levels of testosterone can lead to reduction in normal sexual functioning. Further decreases in serum testosterone can have a negative impact on normal sexual function, leading to a decline in quality of life.
What is ADT treatment?

Can you restart ADT injections?
Occasionally ADT injections are given in cycles and continue until your PSA level is low. Injections can be restarted if your PSA rises again. This is known as intermittent ADT. In some cases, this can reduce side effects. It is not suitable for everyone.

Types
• Orchiectomy (surgical castration)
It consists of removing the testicles, the organ where androgens are synthesized, of the cancer sufferers. It is the most radical treatment for ending the production of androgens. Moreover it is the easiest and least expensive one. The main disadvantage is that surgical castration is a permanent method.
Effects on men's sexuality
Normal male sexuality seems to depend upon very specific and complicated hormonal patterns that are not completely understood. One study suggests that ADT can alter the hormonal balance necessary for male sexual activity. As men age, testosterone levels decrease by about 1% a year after age 30; however, it is important to determine whether low testosterone is due to normal aging, or to a disease, such as hypogonadism. Testosterone plays a significant role in sexual fun…
Adverse effects
Although targeting the androgen axis has clear therapeutic benefit, its effectiveness is temporary, as prostate tumor cells adapt to survive and grow. The removal of androgens has been shown to activate epithelial–mesenchymal transition (EMT), neuroendocrine transdifferentiation (NEtD) and cancer stem cell-like gene programs.
• EMT has established roles in promoting biological phenotypes associated with tumor progressi…
