Radiation therapy for prostate cancer: What to expect

Patients who receive any type of radiation therapy to treat their prostate cancer can have side effects. Short term side effects are ones that start during or shortly after your radiation treatment. Below is a list of possible short term side effects. Treatments can affect each patient differently, and you may not have these particular side effects. Talk with your care team about what you can expect from your treatment

Radiation Therapy In Advanced Disease:

Some forms of radiation therapy, like external radiation therapy and radiopharmaceuticals, can help with advanced prostate cancer. One type of external radiation therapy is used along with hormone therapy to treat cancer that has spread outside the prostate to nearby tissue. In addition, radiopharmaceuticals are used to manage pain and symptoms of bone metastases. Scroll down to learn more about radiopharmaceuticals.

What Types Of Radiotherapy Are There

There are two common types of external beam radiotherapy:

  • intensity-modulated radiotherapy
  • 3-dimensional conformal radiotherapy .

You may also hear about image guided radiotherapy . This is part of all radiotherapy treatments. Taking images of the prostate before each treatment allows your radiographer to make small changes to the area that is going to be treated, in case the prostate has moved slightly since your last treatment session. This makes sure the surrounding healthy tissue gets as little radiation as possible. It also makes sure the whole prostate is treated.

Intensity-modulated radiotherapy

This is the most common type of external beam radiotherapy in the UK. A computer uses the scans from your radiotherapy planning session to map the location, size and shape of your prostate. The radiotherapy machine gives beams of radiation that match the shape of the prostate as closely as possible. This helps to avoid damaging the healthy tissue around it, reducing the risk of side effects.

The strength of the radiation can be controlled so that different areas get a different dose. This means a higher dose of radiation can be given to the prostate without causing too much damage to surrounding tissue.

3D conformal radiotherapy

As with IMRT, the radiation beams are mapped to the size, shape and position of the prostate. But the strength of the radiation cant be controlled in 3D-CRT, so all areas are treated with the same dose.

Other types of radiotherapy

Proton beam therapy

A Biopsy Is Done To Diagnose Prostate Cancer And Find Out The Grade Of The Cancer

A transrectal biopsy is used to diagnose prostate cancer. A transrectal biopsy is the removal of tissue from the prostate by inserting a thin needle through the rectum and into the prostate. This procedure may be done using transrectal ultrasound or transrectal MRI to help guide where samples of tissue are taken from. A pathologist views the tissue under a microscope to look for cancer cells.

Sometimes a biopsy is done using a sample of tissue that was removed during a transurethral resection of the prostate to treat benign prostatic hyperplasia.

If cancer is found, the pathologist will give the cancer a grade. The grade of the cancer describes how abnormal the cancer cells look under a microscope and how quickly the cancer is likely to grow and spread. The grade of the cancer is called the Gleason score.

To give the cancer a grade, the pathologist checks the prostate tissue samples to see how much the tumor tissue is like the normal prostate tissue and to find the two main cell patterns. The primary pattern describes the most common tissue pattern, and the secondary pattern describes the next most common pattern. Each pattern is given a grade from 3 to 5, with grade 3 looking the most like normal prostate tissue and grade 5 looking the most abnormal. The two grades are then added to get a Gleason score.

The Grade Group And Psa Level Are Used To Stage Prostate Cancer

The stage of the cancer is based on the results of the staging and diagnostic tests, including the prostate-specific antigen test and the Grade Group. The tissue samples removed during the biopsy are used to find out the Gleason score. The Gleason score ranges from 2 to 10 and describes how different the cancer cells look from normal cells under a microscope and how likely it is that the tumor will spread. The lower the number, the more cancer cells look like normal cells and are likely to grow and spread slowly.

The Grade Group depends on the Gleason score. See the General Information section for more information about the Gleason score.

  • Grade Group 1 is a Gleason score of 6 or less.
  • Grade Group 2 or 3 is a Gleason score of 7.
  • Grade Group 4 is a Gleason score 8.
  • Grade Group 5 is a Gleason score of 9 or 10.

The PSA test measures the level of PSA in the blood. PSA is a substance made by the prostate that may be found in an increased amount in the blood of men who have prostate cancer.

If Treatment Does Not Work

Recovery from cancer is not always possible. If the cancer cannot be cured or controlled, the disease may be called advanced or terminal.

This diagnosis is stressful, and for many people, advanced cancer may be difficult to discuss. However, it is important to have open and honest conversations with your health care team to express your feelings, preferences, and concerns. The health care team has special skills, experience, and knowledge to support patients and their families and is there to help. Making sure a person is physically comfortable, free from pain, and emotionally supported is extremely important.

People who have advanced cancer and who are expected to live less than 6 months may want to consider hospice care. Hospice care is designed to provide the best possible quality of life for people who are near the end of life. You and your family are encouraged to talk with the health care team about hospice care options, which include hospice care at home, a special hospice center, or other health care locations. Nursing care and special equipment, including a hospital bed, can make staying at home a workable option for many families. Learn more about advanced cancer care planning.

After the death of a loved one, many people need support to help them cope with the loss. Learn more about grief and loss.

What Are The Advantages And Disadvantages Of External Beam Radiotherapy

What may be important for one person might not be so important for someone else. If youre offered external beam radiotherapy, speak to your doctor, nurse or radiographer before deciding whether to have it. They can tell you about any other treatment options and help you decide if radiotherapy is right for you.

Advantages of external beam radiotherapy

  • If your cancer is localised or locally advanced, radiotherapy will aim to get rid of the cancer completely.
  • Many men can carry on with many of their normal activities while having treatment, including going to work and driving.
  • Radiotherapy can be an option even if youre not fit or well enough for surgery.
  • Radiotherapy is painless .
  • The treatment itself only lasts around 10 minutes, including the time it takes to get you into position. But youll probably need to be at the hospital for up to an hour each day to prepare for your treatment. You dont need to stay in hospital overnight.

Side Effects Of Ebrt For Prostate Cancer

How Do You Know Radiation Treatment for Prostate Cancer Worked?

Many of the possible side effects of radiation therapy for prostate cancer involve the bladder and bowelthe prostate is very close to both. Although the goal is to target only the prostate with radiation, sometimes small amounts may cause problems to nearby areas of the body.

Some of the potential side effects from EBRT include:

  • Bowel problems, including diarrhea, leakage or rectal bleeding
  • Urinary symptoms, such as a need to urinate more frequently, incontinence or a burning sensation during urination

Are There Any Long

Long-term risks are slight, but do exist. Its rare but possible that a patient will suffer worsening urinary and rectal function, and there is always a risk of radiation causing cancer.

“Because there are some risks, albeit small ones, we do not treat a patient unless we believe that we can have a real impact on his survival,” says Dr. Yu. For a patient with a very slow-growing cancer, we typically monitor instead of advising immediate treatment.”

Signs Of Prostate Cancer Include A Weak Flow Of Urine Or Frequent Urination

These and other signs and symptoms may be caused by prostate cancer or by other conditions. Check with your doctor if you have any of the following:

  • Weak or interrupted flow of urine.
  • Sudden urge to urinate.
  • Frequent urination .
  • Trouble starting the flow of urine.
  • Trouble emptying the bladder completely.
  • Pain or burning while urinating.
  • Blood in the urine or semen.
  • A pain in the back, hips, orpelvis that doesn’t go away.
  • Shortness of breath, feeling very tired, fast heartbeat, dizziness, or pale skin caused by anemia.

Other conditions may cause the same symptoms. As men age, the prostate may get bigger and block the urethra or bladder. This may cause trouble urinating or sexual problems. The condition is called benign prostatic hyperplasia , and although it is not cancer, surgery may be needed. The symptoms of benign prostatic hyperplasia or of other problems in the prostate may be like symptoms of prostate cancer.

What Happens During Radiation Therapy Treatment

What happens during your radiation therapy treatment depends on the kind of radiation therapy you receive.

External-beam radiation therapy

External-beam radiation therapy delivers radiation from a machine outside the body. It is the most common radiation therapy treatment for cancer.

Each session is quick, lasting about 15 minutes. Radiation does not hurt, sting, or burn when it enters the body. You will hear clicking or buzzing throughout the treatment and there may be a smell from the machine. Typically, people have treatment sessions 5 times per week, Monday through Friday. This schedule usually continues for 3 to 9 weeks, depending on your personal treatment plan.

This type of radiation therapy targets only the tumor. But it will affect some healthy tissue surrounding the tumor. While most people feel no pain when each treatment is being delivered, effects of treatment slowly build up over time and may include discomfort, skin changes, or other side effects, depending on where in the body treatment is being delivered. The 2-day break in treatment each week allows your body some time to repair this damage. Some of the effects may not go away until the treatment period is completed. Let the health care professionals if you are experiencing side effects. Read more about the side effects of radiation therapy.

What Are Male Sex Hormones

Radiation Therapy For Prostate Cancer Near Me

Hormones are substances that are made by glands in the body. Hormones circulate in the bloodstream and control the actions of certain cells or organs.

Androgens are a class of hormones that control the development and maintenance of male characteristics. The most abundant androgens in men are testosterone and dihydrotestosterone .

Androgens are required for normal growth and function of the prostate, a gland in the male reproductive system that helps make semen. 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 .

How Does Brachytherapy Work

Brachytherapy involves implanting small, permanent radioactive seeds or temporary needles into the cancerous prostate.

After you are identified as a good candidate for brachytherapy, an ultrasound is used to guide the placement of needles into the prostate. Depending on whether you and your doctor have chosen permanent/low-dose brachytherapy or temporary/high-dose brachytherapy, these needles are then used to either put in permanent seeds or temporary radiation sources.

Placement of seeds is a minimally invasive procedure and does not require incisions. Men undergoing the procedure can return to full activity in less than a week. This is done as an outpatient procedure before you begin treatment.

Possible Side Effects Of Radiation Treatment

There are possible side effects associated with radiation therapy. Some people may not experience any side effects. Others may experience mild or bothersome side effects.

Some side effects may only last a short period of time, and others may last longer or forever. Side effects may occur at the time of treatment or could develop months after treatment.

Most side effects are manageable by your radiation team and last only a short time. Before starting treatment, your doctor will discuss possible side effects and their duration.

Because we use advanced targeting technology, the probability of side effects is lower.

Possible side effects include:

Bowel Issues Because radiation treatment is so close to the rectum, it could cause irritation. This irritation could cause soreness, blood in your stool, or rectal leakage. Most of the time these issues are temporary, but in rare cases, normal bowel function does not return. Because patients use a rectal balloon during each treatment, the likelihood of rectal issues is lower.

Urinary Issues Radiation can cause irritation to the bladder. This can cause urinary frequency, urgency and a burning sensation. If these problems occur, they generally go away after time.

Keeping your activity level up will result in less fatigue and feeling better.

Radiation Therapy for Prostate Cancer – Short Video

This technique uses advanced image guided techniques to deliver large doses of radiation to a precise area, such as the prostate. Because there are large doses of radiation in each dose, the entire course of treatment is given over just a few days.

SBRT is often known by the names of the machines that deliver the radiation, such as Gamma Knife®, X-Knife®, CyberKnife®, and Clinac®.

The main advantage of SBRT over IMRT is that the treatment takes less time . The side effects, though, are not better. In fact, some research has shown that some side effects might actually be worse with SBRT than with IMRT.

There Are Three Ways That Cancer Spreads In The Body

Cancer can spread through tissue, the lymph system, and the blood:

  • Tissue. The cancer spreads from where it began by growing into nearby areas.
  • Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
  • Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.
