Q: Is Radiation Therapy Safe
Radiation therapy is safe when you go to a center that has a lot of experience and a system for quality assurance. Multiple members of our team look at a plan before its ever applied to a patient, says Dr. Gejerman.
Treatments For Prostate Cancer
If you have prostate cancer, your healthcare team willcreate a treatment plan just for you. It will be based on your health andspecific information about the cancer. When deciding which treatments to offerfor prostate cancer, your healthcare team will consider:
Impotence Risks After Prostatectomy
Unfortunately, impotence continues to be a risk for radical prostatectomy. The recovery of potency depends on the stage of disease, the age of the patient, and the skill of the surgeon. However, a loss of potency can be treated with a number of technologies including medications, injections, and erectile devices.
Recurrence Risk With Radiation Vs Surgery For Prostate Cancer
The fear of incontinence may be another deciding factor for some patients. Fortunately, especially with the advent of robotic surgery, most patients are able to become continent after a few weeks to months of stress incontinence.
How Does Hormone Therapy Work Against Prostate Cancer
Early in their development, prostate cancers need androgens to grow. Hormone therapies, which are treatments that decrease androgen levels or block androgen action, can inhibit the growth of such prostate cancers, which are therefore called castration sensitive, androgen dependent, or androgen sensitive.
Frequent Urination Burning With Urination And Difficulty Urinating
These are the most common complaints. Occasionally the urinary stream will weaken. Generally these symptoms are managed with medications to help the bladder function better or eliminate burning. Rarely, your doctor may order a urine test. Symptoms will resolve after the end of treatment.
What The Results Showed
What Chesnut and his colleagues wanted to know was if the mens pre-operative findings were consistent with tumor details in their surgically removed prostates. And that turned out to be the case.
How long does radiation treatment last?
You will usually go for treatment 5 days a week in an outpatient center for at least several weeks, depending on why the radiation is being given. Each treatment is much like getting an x-ray. The radiation is stronger than that used for an x-ray, but the procedure typically is painless.
What type of radiation is used for prostate cancer?
The main types of radiation therapy used for prostate cancer are: External beam radiation. Brachytherapy (internal radiation) (Another type of radiation therapy, in which a medicine containing radiation is injected into the body, is described in Treating Prostate Cancer Spread to the Bone .)
What is the best treatment for prostate cancer?
Brachytherapy (internal radiation therapy) 1 Brachytherapy alone is generally used only in men with early-stage prostate cancer that is relatively slow growing (low-grade). 2 Brachytherapy combined with external radiation is sometimes an option for men who have a higher risk of the cancer growing outside the prostate.
How does proton beam therapy work?
Proton beam therapy focuses beams of protons instead of x-rays on the cancer. Unlike x-rays, which release energy both before and after they hit their target, protons cause little damage to tissues they pass through and release their energy only after traveling a certain distance. This means that proton beam radiation can, in theory, deliver more radiation to the prostate while doing less damage to nearby normal tissues. Proton beam radiation can be aimed with techniques similar to 3D-CRT and IMRT.
Why do you put a balloon between your prostate and your rectum?
Sometimes a balloon-like device or gel is put between the rectum and the prostate before treatment to act like a spacer to lessen the amount of radiation that reaches the rectum. Urinary problems: Radiation can irritate the bladder and lead to a condition called radiation cystitis.
What is EBRT radiation?
In EBRT, beams of radiation are focused on the prostate gland from a machine outside the body. This type of radiation can be used to try to cure earlier stage cancers, or to help relieve symptoms such as bone pain if the cancer has spread to a specific area of bone.
What is IGRT prostate?
Some newer radiation machines have imaging scanners built into them. This advance, known as image guided radiation therapy (IGRT), lets the doctor take pictures of the prostate just before giving the radiation to make minor adjustments in aiming.
What are the drugs that help prostate cancer grow?
Anti-androgens. 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.
What does CSPC mean in prostate cancer?
Castrate-sensitive prostate cancer (CSPC) means the cancer is being controlled by keeping the testosterone level as low as what would be expected if the testicles were removed (called the castrate level ).
What is the goal of hormone therapy?
The goal is to reduce levels of male hormones, called androgens, in the body, or to stop them from fueling prostate cancer cells. Androgens stimulate prostate cancer cells to grow. The main androgens in the body are testosterone ...
What hormones are used to remove testicles?
Estrogens (female hormones) were once the main alternative to removing the testicles (orchiectomy) for men with advanced prostate cancer. Because of their possible side effects (including blood clots and breast enlargement), estrogens have been replaced by other types of hormone therapy.
Where is androgen made?
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. Lowering androgen levels or stopping them from getting into prostate cancer cells often makes prostate cancers shrink or grow more slowly 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.
Can prostate cancer cause pain in the spine?
Men whose cancer has spread to the bones may have bone pain. Men whose prostate gland has not been removed may have trouble urinating. If the cancer has spread to the spine, even a short-term increase in tumor growth as a result of the flare could press on the spinal cord and cause pain or paralysis.
How long does radiation therapy last after prostatectomy?
The findings of the 2016 trial indicated that radiation plus a course of androgen deprivation therapy for 6 months could be a treatment option for men who experience a biochemical recurrence after a prostatectomy.
Why is there a longer follow up on prostate cancer?
Because prostate cancer can progress slowly, the researchers wanted longer-term follow-up to determine whether some participants could be considered cured of their disease. In his editorial, Dr. Thompson highlighted this aspect of the research.
How long did Casodex last?
In the trial, participants were randomly assigned to receive bicalutamide (Casodex®) or a placebo for 24 months , along with 6.5 weeks of radiation therapy. When the trial began in 1998, bicalutamide was a commonly used treatment to prevent androgens (male sex hormones) from fueling the growth and spread of tumors in men with prostate cancer.
Does combination therapy help prostate cancer?
Combination Therapy Improves Survival for Some Men with Recurrent Prostate Cancer. Antiandrogens like bicalutamide compete with androgens for binding to the androgen receptor, reducing the ability of androgens to promote prostate cancer cell growth. Adding androgen deprivation therapy to radiation therapy can improve survival for some men ...
Is Lupron a radiation medicine?
In recent years, drugs such as leuprolide acetate (Lupron®) have largely replaced bicalutamide as an adjunct to radiation. Two major clinical trials that began about 5 years ago are testing some of these agents in combination with radiation. “It will take some time to get their results,” Dr. Shipley noted.
Does androgen deprivation help prostate cancer?
Adding androgen deprivation therapy to radiation therapy can improve survival for some men with recurrent prostate cancer, according to the long-term results of a clinical trial. The combination therapy was also associated with a lower rate of metastases and death due to prostate cancer, compared with radiation alone.
How do androgens affect prostate cancer?
Androgens act as a sort of messenger, affecting the behavior of both healthy and cancerous prostate cells by binding to and activating androgen receptors (proteins) that are expressed in prostate and PCa cells . In turn, the androgen receptor “regulates a transcriptional program of DNA repair genes that promotes prostate cancer radioresistance …”.
How do androgens help cancer cells?
They observed that when androgens stimulate androgen receptor signal ing, the PCa cells increased the expression of DNA repair genes (i.e. made more of them) which then accelerated the repair of radiation-caused cancer cell damage. Thus, by triggering androgen receptors, androgens helped cancer cells resist radiation.
How do androgen receptors work?
In the presence of male hormones, androgen receptors are activated in a way that “switches on” a DNA repair gene that helps the PCa cell survive the effects of radiation exposure. So, in theory, depriving them of androgens weakens them.
What is ADT in prostate cancer?
Androgen deprivation therapy (ADT) is a therapeutic, non-curative approach to controlling prostate cancer (PCa). It is most often prescribed for advanced or recurrent PCa when a local treatment is not appropriate or has failed; more recently it is also being seen as a “boost” for primary radiation therapy, and even in some cases a way to extend the duration of Active Surveillance.
What hormones help prostate cancer?
Male hormones help prostate cancer cells. Prostate cancer cells thrive on androgens (male sex hormones), the most abundant of which are testosterone and dihydrotestosterone. The normal growth and function of the prostate gland depends upon androgens, and so do PCa cells. Androgens act as a sort of messenger, affecting the behavior ...
What does ADT stand for in radiation?
This saying also captures something that mystified urology/radiation oncology teams for two decades. Androgen deprivation therapy (ADT) boosts the effectiveness of radiation therapy as a primary prostate cancer treatment.
Why is radiation harmful to cells?
Radiation is harmful to cells because it damages DNA, the core instruction manual for a living being to develop, survive and reproduce.

Risks Of The Procedure
As with any surgical procedure, certain complications can occur. Somepossible complications of both the retropubic and perineal approaches to RPmay include:
Rising Psa Without Evidence Of Metastases
Nubeqa® is an androgen receptor inhibitor with a distinct chemical structure that competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription approved for the treatment of men with non-metastatic castration-resistant prostate cancer .
What Happens To The Prostate After Radiation
The entire prostate gland is radiated when we treat the cancer. The prostate normally produces some of the fluid in the ejaculation. Radiation therapy has the side effect of damaging the glands in the prostate, so a lot less fluid is produced. The ejaculation may be dry or nearly dry.
Salvage Androgen Deprivation Therapy
Recurrence following RP can potentially be managed with salvage ADT, although data supporting this use is generally obtained from retrospective studies .
External Beam Radiation Therapy
In this type of therapy, a machine outside the body is used to focus the beams of radiation on the prostate gland. It is used to treat early stages of cancer and helps to relieve you from symptoms such as pain.
How To Return To An Active Sex Life After Prostate Cancer Treatment
No matter the cancer, treatments often cause side effects that affect patients quality of life. But with prostate cancer, the potential side effects can be particularly concerning to men who are trying to decide which approach is right for them.
