Diminution Of Muscular Strength
A mans muscular strength is reduced by 12% to 66% as the result of androgen deprivation. Moreover, muscle mass declines by 20% to 30% by age 70 . Because androgen deprivation reduces the amount of protein synthesis and the non-lipid body mass, obesity results. Thus, elderly patients should actively work against the loss of muscle by directed strength-training exercises .
Addition Of Other Therapies In The Hormone
As in many other malignancies, we have learned that combination therapy at the outset of treatment improves long-term disease control and survival outcomes. Both docetaxel and abiraterone acetate in the hormone-sensitive setting have demonstrated a survival benefit when added to standard ADT . Based on these data, most providers should offer, or at least consider, additional therapies to treat patients at this stage. Certainly in a frail patient population, one must continue to assess the overall fitness of a patient. Any patient already thought of as fit should be offered unaltered therapy. Those found to be vulnerable or frail could be considered based on the ability to reverse at-risk conditions.
Abiraterone acetate and prednisone
The patients enrolled in the LATITUDE and STAMPEDE-abiraterone trials were generally older , with ECOG scores of 02 compared with the CHAARTED and STAMPEDE-chemotherapy cohorts. Of note, patients being treated with abiraterone must take a low-dose corticosteroid to avoid mineralocorticoid excess, which results from alteration of adrenal function. In addition, patients may not have the means to pay for this costly agent, since older patients usually have a fixed income. Overall, there is little need for dose interruptions or reductions of abiraterone, and it should be considered for a broad group of older patients with newly diagnosed metastatic hormone-sensitive prostate cancer.
What Is The Life Expectancy Of Someone With Metastatic Prostate Cancer
In the past, the life expectancy of men with metastatic prostate cancer was 2-3 years. But with advancements in medicine and care, the life expectancy of men with metastatic prostate cancer has increased to about 5-6 years.
The 5-year survival rate of metastatic prostate cancer is 28%, which is much lower than local and regional prostate cancers. This refers to the percentage of people diagnosed with a particular cancer who can expect to live for at least 5 years after diagnosis.

How Often You Have Hormone Therapy
You usually have hormone therapy that you take all the time . Or you may have a few months of treatment and then a break . Its thought that having intermittent therapy might reduce the side effects you get, but more research needs to be done to look into this.
You might have:
- one hormone therapy drug on its own
- two hormone therapies together
- hormone therapy with chemotherapy, such as docetaxel
Your doctor will talk to you about which hormone therapy they recommend and for how long you might have take it for.
First Line Treatment For Advanced Prostate Cancer
The established first line approach is to control the progression of the disease by reducing levels of testosterone in the body. This is because testosterone increases the speed at which prostate cancer cells reproduce.
There are two different ways to lower testosterone levels. Hormone therapy lowers the levels of testosterone in the body by taking tablets or having injections. It is sometimes referred to as medical castration. The surgical option involves removing the testicles, known as surgical castration or orchidectomy, although this is now rarely used.
Another approach is called anti-androgen treatment. Androgens have to bind to a protein in the cell called an androgen receptor to work. Anti-androgens are drugs that bind to these receptors so the androgens cant, effectively blocking them. The main side-effects are gynaecomastia breast enlargement and breast pain, although a single radiotherapy dose to the breasts can help this side-effect.
Combining anti-androgens with testosterone reduction is known as Maximum Androgen Blockade and may be used if hormone treatment alone is not working sufficiently.
Treating with chemotherapy at the same time as the start of hormone deprivation was found to increase survival by 13 months in all patients and 17 months in men with high-volume disease.

How Is Prostate Cancer Diagnosed
Doctors describe the growth and spread of prostate cancer in stages. Doctors use these stages as guides when choosing treatment options or offering prognoses to their patients.
Prostate cancer staging is based on a number of different factors, including prostate cancer screening tests such as a digital rectal exam or prostate-specific antigen test and imaging studies like bones scans, MRIs, CT scans, and trans-rectal ultrasounds.
What Is Hormone Therapy
The idea that hormones have an effect on prostate cancer is not new. The scientist Charles Huggins first established this over 60 years ago in work that led to his winning the Nobel Prize. Huggins found that removing one of the main sources of male hormones from the body — the testicles — could slow the growth of the disease.
“This procedure worked dramatically,” says Holden, who is also director of the Prostate Cancer Center at Cedar Sinai Medical Center in Los Angeles. “Before, these men were confined to bed and wracked with pain. Almost immediately afterwards, they improved.”
Huggins found that some types of prostate cancer cells need certain male hormones — called androgens — to grow. Androgens are responsible for male sexual characteristics, like facial hair, increased muscle mass, and a deep voice. Testosterone is one kind of androgen. About 90% to 95% of all androgens are made in the testicles, while the rest are made in the adrenal glands located on top of the kidneys.

Survival Rates For Bladder Cancer
Survival rates can give you an idea of what percentage of people with the same type and stage of cancer are still alive a certain amount of time after they were diagnosed. They cant tell you how long you will live, but they may help give you a better understanding of how likely it is that your treatment will be successful.
Keep in mind that survival rates are estimates and are often based on previous outcomes of large numbers of people who had a specific cancer, but they cant predict what will happen in any particular persons case. These statistics can be confusing and may lead you to have more questions. Talk with your doctor about how these numbers may apply to you, as he or she is familiar with your situation.

What Are Male Sex Hormones
Androgens are required for normal growth and function of the prostate, a gland in the male reproductive system that helps make . 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 . Once activated, the androgen receptor stimulates the expression of specific genes that cause prostate cells to grow .
Almost all testosterone is produced in the testicles a small amount is produced by the adrenal glands. Although prostate cells do not normally make testosterone, some prostate cancer cells acquire the ability to do so .

First, it is a single, simple, surgical procedure with a very low risk of problems and 100 percent efficacy.
Second, it can be carried out in ways which are not physically evident. In other words, it is possible to carry out what is known as a subcapsular orchiectomy, in which the cores of the two testes are removed while the capsules remain in the scrotum. This means that the man still appears to be an intact male.
A New Treatment Standard
Still, some men have difficulty tolerating ADT, and not all of them should get it, particularly if theyre older and more likely to die of something other than prostate cancer. Id reserve ADT for younger men with a long life expectancy ahead of them who were diagnosed initially with high-grade or late-stage disease, Thompson said.
This important study confirms that combined therapy is superior to radiation alone and should be viewed as the standard treatment for PSA relapse, said Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, and editor in chief of HarvardProstateKnowledge.org. High dose bicalutamide has been associated with cardiovascular side effects, but ongoing and future research is clarifying how best to use ADT in this particular setting.

What Type Of Hormone Therapy Works Best
Unfortunately, understanding the details of hormone therapy for prostate cancer can be difficult. Which drug or combination of drugs works best? In what order should they be tried? Research hasnt answered these questions yet.
Right now, theres a level of art to figuring out which agents to use, says Durado Brooks, MD, MPH, director of prostate cancer programs at the American Cancer Society. We dont have clear evidence yet.
LHRH agonists remain the usual first treatment. But in some cases, doctors are trying anti-androgens first. Anti-androgens may be especially appealing to younger men who are still sexually active, since these drugs dont completely shut down sex drive. When anti-androgens stop working based on PSA tests a person then might shift onto an LHRH agonist.
Other doctors prefer to begin therapy with a combination of two or even three drugs, especially for patients with symptoms or advanced disease, says Holden.
Researchers originally hoped that combined androgen blockade would significantly add to the benefits of LHRH agonists. However, the results, to date, have been mixed. Some studies have shown slightly longer survival with combined androgen blockade, but the results havent been as dramatic as many experts had hoped. Other studies have shown no benefit. A possible explanation may be the type of anti-androgen used, but further studies are needed to answer this question.
What Is A 5
A relative survival rate compares people with the same type and stage of cancer to people in the overall population. For example, if the 5-year relative survival rate for a specific stage of prostate cancer is 90%, it means that men who have that cancer are, on average, about 90% as likely as men who dont have that cancer to live for at least 5 years after being diagnosed.

What Is Intermittent Adt
Researchers have investigated whether a technique called intermittent androgen deprivation can delay the development of hormone resistance. With intermittent androgen deprivation, hormone therapy is given in cycles with breaks between drug administrations, rather than continuously. An additional potential benefit of this approach is that the temporary break from the side effects of hormone therapy may improve a mans quality of life.
Randomized clinical trials have shown similar overall survival with continuous ADT or intermittent ADT among men with metastatic or recurrent prostate cancer, with a reduction in some side effects for intermittent ADT .

Another type of prostate issue is chronic prostatitis, or chronic pelvic pain syndrome. This condition causes pain in the lower back and groin area, and may cause urinary retention. Symptoms include leaking and discomfort. In severe cases, a catheter may be required to relieve the symptoms. If the problem is unresponsive to other treatments, your doctor may suggest a surgical procedure. If these do not work, your symptoms could progress and become chronic.
An acute bacterial infection can cause a burning sensation. Inflammation of the prostate can affect the bladder and result in discomfort and other symptoms. This is the most common urinary tract problem in men under 50, and the third most common in men over 65. The symptoms of acute bacterial prostatitis are similar to those of CPPS. Patients may experience a fever or chills as a result of the infection.
Know Your Priorities When Deciding On Prostate Cancer Treatment
While this one study showed that people who get a prostatectomy may live longer, its important to understand the risks involved with each and to know your priorities. You may be quick to want to remove your prostate or get radiation treatment to get rid of the cancer right away, however, there are many quality of life issues to take into account:
- With active surveillance, your cancer may grow and spread.
- Choosing not to treat your cancer right away could lead to anxiety.
- Men who undergo radiation are more likely to have bowel problems.
- There is a chance you may lose bladder control after surgery.
- You may lose your ability to have an erection after surgery.
The decision about how you will treat your prostate cancer is not one to be taken likely. Discussing the risks and complications with your physician and your family, and thoroughly considering your priorities, can help you make a decision that feels right for you.

Management Of Metastatic Prostate Cancer In Frail/elderly Patients
Elizabeth R. Kessler, MDOncology
In this article, we discuss the importance of assessing frail and elderly prostate cancer patients before starting treatment and making adjustments to the choice of therapy, or supportive services, in order to maximize benefit and minimize potential harms.
As the world population ages, we can expect to care for an increasing number of older cancer patients. Prostate cancer is inherently a condition that affects patients of advanced age. In caring for these patients who have advanced prostate cancer, it is important to first assess the health status of the patient and his goals of care. As this is established, likely through a geriatric assessment, this will inform how to modify or mold the treatment plan to fit a patients needs and vulnerabilities. These vulnerabilities may surface as patients undergo treatment such as androgen deprivation therapy-the backbone of systemic therapy for advanced disease. Androgen deprivation therapy leads to long-term adverse effects therefore, providers should carefully consider its use and proactively manage toxicity. It is important to assess patients before starting treatment and to adjust the choice of therapy, or supportive services, in order to maximize benefit and minimize potential harms.
