Intermittent Hormonal Therapy For Locally Advanced Prostate Cancer

Hormone Therapy for Prostate Cancer

Intermittent hormonal therapy is where you stop taking the drugs and after a while start taking them again. This may be an option for locally-advanced prostate cancer. It gives you a break from the side effects of hormonal therapy.

Intermittent hormonal therapy is not suitable for everyone and should only be done on your doctors advice. Your doctor can explain more about this. They usually measure your PSA level using the PSA test every 3 months. If it goes up to a certain level or you get symptoms, your doctor will advise you to start hormonal therapy again.

How Are Hormone Therapy Medicines Used

Hormone therapy medicines may be used alone, with another type of hormone therapy, or with another type of prostate cancer treatment.

Monotherapy

Monotherapy is when only one type of hormone therapy medicine is used to lower the amount of testosterone in your body. Monotherapy can be effective in shrinking a prostate cancer tumor, slowing the spread of your prostate cancer, and relieving pain caused by your prostate cancer. Monotherapy may be used with neoadjuvant therapy or adjuvant therapy. Please read When is Hormone Therapy Used for Prostate Cancer? to learn more about neoadjuvant and adjuvant therapy.

Combination therapy

How Might I Feel During Hormone Therapy

Nearly all men being treated for prostate cancer say that they feel emotionally upset at different times during their hormone therapy. It’s not unusual to feel anxious, depressed, afraid, angry, frustrated, alone, or helpless. Hormone therapy may affect your emotions because it lowers the amount of testosterone in your body.

Some men find it helps to learn about their disease and treatment because it makes them less afraid of their treatment. Find out as much as you want to know. Do not be afraid to ask questions. Your emotional health is as important as your physical health.

Talking with an understanding friend, relative, minister or another patient may be helpful. Your doctors office may be able to give you a list of local prostate cancer support groups. There will be men in the support groups who have had hormone therapy. You may also contact the American Cancer Society at 1-800-227-2345 or the National Cancer Institutes Cancer Information Line at 1-800-422-6237 to find out about cancer resources in your local community.

Many people don’t understand prostate cancer or its treatment. They may stay away from you because they’re not sure what to say or how to help. Try to be open when you talk to other people about your illness, treatment, needs, and feelings. People will often be willing to lend their support. If you get tired easily, limit your activities and do only the things that mean the most to you.

Secondary Treatment Following Relapse

Hormone therapy may also be used as a secondary or salvage treatment when PSA levels rise following initial prostate cancer treatment, indicating the cancer has returned. This situation is known as biochemical recurrence. The salient points to keep in mind are that hormone therapy is most often used as a salvage treatment when PSA doubling time is less than six months, indicating that the cancer is aggressive or may have already metastasized.

Outlook For Locally Advanced Prostate Cancer

Prostate Cancer

Many men with locally advanced prostate cancer have treatment that aims to get rid of their cancer. For some men, this treatment can be very successful and they may live for many years without their cancer coming back or causing them any problems. For others, treatment may be less successful and the cancer may come back. If this happens, you might need further treatment. Read more about the risk of your cancer coming back.

Some men with locally advanced prostate cancer will have treatment that aims to help keep their cancer under control rather than get rid of it completely. For example, if you have hormone therapy on its own, it can help to keep the cancer under control, usually for several years. And there are other treatments available if your hormone therapy stops working.

For early prostate cancer this depends on the prostate cancer risk group. If the cancer is:

  • intermediate-risk you may have hormonal therapy for a few months after radiotherapy
  • high-risk you may be advised to have hormonal therapy for up to 2 to 3 years after radiotherapy.

For locally advanced prostate cancer you usually have hormonal therapy for 2 to 3 years after radiotherapy.

Nutrition And Dietary Supplements

Some studies have suggested that eating a healthy diet that is rich in vegetables and lower in animal fats might be helpful, but more research is needed to be sure. However, we do know that a healthy diet can have positive effects on your overall health, with benefits that extend beyond your risk of prostate or other cancers.

So far, no dietary supplements have been shown to clearly help lower the risk of prostate cancer progressing or coming back. In fact, some research has suggested that some supplements, such as selenium, might even be harmful. This doesnt mean that no supplements will help, but its important to know that none have been proven to do so.

Dietary supplements are not regulated like medicines in the United States they do not have to be proven effective before being sold, although there are limits on what theyre allowed to claim they can do. If you are thinking about taking any type of nutritional supplement, talk to your health care team. They can help you decide which ones you can use safely while avoiding those that could be harmful.

Prostate Cancer Survival By Age

Five-year survival for prostate cancer shows an unusual pattern with age: survival gradually increases from 91% in men aged 15-49 and peaks at 94% in 60-69 year olds survival falls thereafter, reaching its lowest point of 66% in 80-99 year olds patients diagnosed with prostate cancer in England during 2009-2013. The higher survival in men in their sixties is likely to be associated with higher rates of PSA testing in this age group.

Surgically Removing The Prostate Gland

Hormone Therapy Basics | Ask a Prostate Cancer Expert, Mark Scholz, MD

A radical prostatectomy is the surgical removal of your prostate gland. This treatment is an option for curing prostate cancer that has not spread beyond the prostate or has not spread very far.

Like any operation, this surgery carries some risks.

A recent trial showed possible long-term side effects of radical prostatectomy may include an inability to get an erection and urinary incontinence.

Before having any treatment, 67% of men said they could get erections firm enough for intercourse.

When the men who had a radical prostatectomy were asked again after 6 months, this had decreased to 12%. When asked again after 6 years, it had slightly improved to 17%.

For urinary incontinence, 1% of men said they used absorbent pads before having any treatment.

When the men who had a radical prostatectomy were asked again after 6 months, this had increased to 46%. After 6 years, this had improved to 17%.

Out of the men who were actively monitored instead, 4% were using absorbent pads at 6 months and 8% after 6 years.

In extremely rare cases, problems arising after surgery can be fatal.

Its possible that prostate cancer can come back again after treatment. Your doctor should be able to explain the risk of your cancer coming back after treatment, based on things like your PSA level and the stage of your cancer.

Treatment options include:

  • hormone treatment

If the cancer has spread to your bones, medicines called bisphosphonates may be used. Bisphosphonates help reduce bone pain and bone loss.

What Is Hormone Herapy

To help you understand what hormone therapy is and how it may affect your prostate cancer, it is good for you to understand what hormones are and how they work in your body. Hormones control or manage your bodys activities. Hormones are made by glands in your body and are carried by your blood to all areas in your body. Glands are groups of cells in your body that make and release materials needed by your body.

Testosterone is the main male hormone in your body. It makes you grow hair on your face and body and have a mans body shape and controls your desire for sex. Testosterone also controls your prostate gland. Your testicles make most of the testosterone in your body. A small amount of testosterone is also made by your adrenal glands. Your adrenal glands are located on top of each kidney. Your adrenal glands also make other hormones.

Prostate cancer is hormone sensitive or hormone dependent. This means that the testosterone in your body helps your prostate cancer to grow. The goal of hormone therapy is to lower the amount of testosterone in your body to stop or slow the growth of your prostate cancer. You can lower the amount of testosterone in your body by taking medicines or having surgery.

Advising The Patient About Hormonal Therapy

How Long After Hormone Therapy For Prostate Cancer ...

Finally, Mark Moyad, MD, Director of Complementary and Preventive Medicine, University of Michigan, Department of Urology and Oncology, delivered an excellent discussion of the 10 steps he takes in advising patients about initiation of androgen deprivation therapy. Step 1 is to introduce patients to the common and less common side effects of androgen deprivation therapy . Step 2 is to introduce the patient to moderate, practical, and realistic dietary and lifestyle changes that promote general health during the androgen deprivation therapy. Dr. Moyad stated that recommendations for cardiovascular well-being extrapolate well to provide benefit to patients receiving androgen deprivation therapy. Step 3 is to emphasize that when it comes to over-the-counter supplements and other alternative approaches, less is more. He emphasized that some of these agents might have adverse effects on surgery or radiation therapy and that patients should discontinue these agents at least 1 week before definitive treatment. Step 4 is to remind patients that there might be dyslipidemia associated with androgen deprivation therapy patients should be told, know your lipid levels as well as your PSA.

Results Of Treating Prostate Cancer With Radiation Therapy

American Cancer Society. Radiation therapy for prostate cancer. January 2013.

Radiation therapy is best used as an early treatment for a lower-grade cancer that is confined within the prostate gland. The survival rates are similar to the results of radical prostatectomy. Radiation therapy treatments can also be used along with hormone therapy as a first step in treating prostate cancer that has spread outside of the prostate gland to nearby tissues. External beam radiation therapy can be focused on the prostate gland therefore, reducing the radiation exposure to the surrounding healthy tissues. This may increase survival rates over other forms of prostate cancer treatments.

National Cancer Institute at the National Institutes of Health. September 2012

Clinical trials show that external-beam radiation therapy does not seem to improve the survival rate of prostate cancer, but it does help to stop the progression of the disease. One such trial showed an increased progression-free survival at 4 years for patients with a 15% estimated risk of lymph node involvement who received whole-pelvic radiation therapy as compared with prostate-only radiation therapy With this in mind, radiation therapy treatments should be delayed 4 to 6 weeks after a TURP procedure in order to reduce incidence of stricture.

Increased Survival Rate In Prostate Cancer Patients With Addition Of Hormone Therapy Treatments

by University Hospitals Cleveland Medical Center

Prostate cancer is the leading cause of cancer in men worldwide, and radiotherapy is one of the common forms of treatment. In a first-of-its kind meta-analysis, published today in The Lancet Oncology, researchers from University Hospitals and Case Western Reserve University show that there is consistent improvement in overall survival in men with intermediate- and high-risk prostate cancer with the addition of hormone therapy to radiotherapy treatments.

Throughout the past 40 years, randomized trials have been conducted on the impact of adding hormone therapy to prostate cancer treatments. While these trials individually show the benefit of hormone therapy, there are inconsistencies in timing and duration of treatment recommendations.

In this analysis, the team made three key discoveries:

1) Men with intermediate- and high-risk prostate cancer have an increased survival rate from the addition of hormone therapy to radiotherapy. This was seen in both younger and older men, and in men treated with lower and higher doses of radiotherapy.

3) The prolongation of neoadjuvant hormone therapy before radiotherapy did not benefit men in any outcome measured. This is an important finding, because some countries routinely give extended durations of hormone therapy before radiotherapy. The team showed that this method isnât advantageous over shorter durations.

Treatment Options For Localized Prostate Cancer

If you are diagnosed with low-risk prostate cancer, you may be presented with a number of different treatment options. The most common include:

  • Active Surveillance: Your doctor may want to monitor your disease to see if treatment is necessary. With active surveillance, you will have regular check-ups with your doctors, and he or she may perform biopsies regularly. If your test results change, your doctor will discuss your options for starting treatment.
  • Watchful Waiting: While some doctors use the terms active surveillance and watchful waiting interchangeably, watchful waiting usually means that fewer tests are done. You will still visit your doctor regularly, but your doctor will discuss changes in your health as they relate to managing your symptoms, not curing your disease.
  • Prostatectomy: Removal of the prostate, called prostatectomy, is an option that has a strong likelihood of removing your cancer since you are removing the gland where it is located. However, this is an invasive procedure that can lead to other issues, which will be covered later.
  • Radiation: Your doctor may suggest radiation as a means of therapy that targets tumors with radiation, usually through daily treatments in a hospital or clinic over multiple weeks.

How Will I Know That The Treatment Has Been Successful

Intermittent Hormone Therapy for Prostate Cancer 101 | Ask a Prostate Expert, Mark Scholz, MD

As with any other prostate cancer treatment option, the postoperative PSA blood test will be the primary indicator of a successful treatment. We will obtain a PSA level three months after the procedure, and then every six months for five years. After five years PSA monitoring is generally done annually. We expect to see the PSA come down to a level well below 0.5 ng/dl and remain at the lowest level achieved. Three successive rises in the PSA after reaching the lowest point would raise concern about residual or recurrent prostate cancer.

Side Effects Of Hormone Therapy

Most side effects experienced by patients receiving HT are caused by low testosterone. The three most reported side effects are fatigue, hot flashes and sexual changes, including decreased libido and reduced erectile function.

Many of these side effects develop over time. Patients treated for eight months or less time are less likely to experience many of them, although some, such as hot flashes and sexual side effects, usually manifest within the first four to six weeks. Most of these side effects are reversible, diminishing or disappearing when the therapy is stopped and testosterone levels recover.

Not all patients experience all side effects, and there is much variability in their severity.

Here are the side effects patients most often report, along with suggestions for minimizing them:

Gross Findings Of Hormonal Effects On Bph And Prostate Cancer

Grossly, prostates from patients treated with luteinizing hormone-releasing hormone analogues or antiandrogens are small, and benign prostatic hypertrophy and carcinoma can be more difficult to identify macroscopically, compared with untreated glands. Treated glands are shrunken and have a rubbery to soft consistency.

What Is Hormonal Therapy For Prostate Cancer

Hormonal therapy for prostate cancer is a treatment to lower the levels of the hormone testosterone in the body. Prostate cancer needs testosterone to grow. Testosterone is mainly made by the testicles. Hormonal therapies reduce the amount of testosterone in the body, or stop it reaching the prostate cancer cells.

Testosterone is important for:

  • muscle development and bone strength.

Hormonal therapies are drugs that can be given as injections or as tablets.
