Intensity-modulated radiotherapy is the standard of care for head and neck cancers, and it shows great promise for the treatment of certain brain and colorectal cancers. More controversially, however, IMRT at some cancer centers has also become a de facto standard of care for prostate cancers.
IMRT, an advanced and more precise external beam radiotherapy introduced in the 1990s, allows another solution to the radiotherapy dilemma: The intensity of the radiation beam is modulated through selective contouring of multiple beam pathways delivered from different directions to maximize tumor radiation doses while minimizing irradiation of healthy tissues along any given beam pathway. Treatment planning is complex, based on 3-D CT imaging and use of computer dosimetric algorithms to calculate the best series of beam pathways for irradiating tumors with irregularly shaped volumes. This approach provides higher cumulative radiation doses to target tissues than can safely be achieved with conventional external beam radiotherapy. CT images obtained between radiation sessions allow recalibration of sculpted irradiation as tumor volume decreases and tumor contours change with treatment. Compared with other radiation modalities, IMRT permits more precise irradiation of concave tumors, including those enveloping nontarget tissues, such as vasculature or the spinal cord.
Last year, prostate cancer was diagnosed in an estimated 217,700 US men, and more than 30,000 died of this malignancy, according to the National Cancer Institute (NCI). 1 Treatment options include surgical removal of the prostate, brachytherapy with radiation pellets placed around the tumor, external beam radiotherapy, chemotherapy, and combinations of these modalities. Surveillance and monitoring of tumor progression is also an option, particularly for men older than 80 years, among whom prostate cancer frequently is a smaller threat to survival than other diseases and medical events.

Prostate resection is associated with sexual impotence and urinary incontinence, for example, and irradiation can cause rectal bleeding. External beam radiation is a frequent component of prostate cancer treatment. As with all radiation therapies, however, this treatment involves the fundamental dilemma of how to deliver therapeutic (ie, ...
2. Fiducials: In many (but not all) cases, the first step in the treatment planning process will be the implantation of several tiny gold markers, known as fiducials, into the prostate. This is a minimally invasive procedure done under local anesthesia.
The major advantage of IGRT / IMRT is that it is adaptable across a wide variety of prostate cancer situations, and as a mature radiation therapy technology, it is recognized for coverage by virtually all insurers. IGRT / IMRT emerges as the preferred treatment option for a wide spectrum of prostate cancer patients.
Radiation Therapy Treatment: Following completion of the simulation process, the scheduled course of daily radiotherapy treatments will begin, typically lasting a total of 6-9 weeks, depending upon the exact situation and course prescribed.
The original step in the process is a thorough review of the patient's medical records, lab results, imaging studies, and physical examination during a consultation that usually lasts about an hour. At the conclusion of this initial consultation a specific treatment recommendation may be made, or in some cases, further diagnostic testing ordered first. If additional tests are ordered there will then be a second brief visit with the radiation oncologist to review the results of the additional tests and determine a final recommendation. For some patients a clear path of action will be evident, while others may choose to seek consultations from additional specialists before making their final treatment decision.
October 23, 2018. Men being treated for early-stage prostate cancer with external beam radiation therapy (EBRT) can safely choose an option that reduces the number of treatment sessions, according to a panel of experts from the American Society for Radiation Oncology, American Society of Clinical Oncology, and American Urological Association.
Men diagnosed with prostate cancer while it’s still at an early stage often have several treatment options, including active surveillance (also called watchful waiting), surgery, or radiation. All have about the same cure rates for the earliest stage prostate cancers, although each type of treatment has pros and cons.
They concluded that hypofractionated radiation therapy is a safe option. Cure rates and side effects are similar to a conventional ERBT treatment schedule. However, there is a slightly greater risk of severe gastrointestinal complications with hypofractionated radiation therapy.
IG-IMRT uses images that are taken in real time to mold the radiation beams to your tumor. Because the normal movements of your body can cause your prostate to move slightly during or between treatments, your healthcare team will insert markers into your prostate.
You may receive radiation therapy either alone or in combination with hormone therapy. Depending on the stage of the cancer, your doctor may recommend hormonal therapy. The goal of hormonal therapy is to shrink the prostate gland and stop the cancer from growing to help make the treatment more effective.
Your body then is naturally able to get rid of these damaged cancer cells. Radiation therapy also affects normal cells. However, your normal cells are able to repair themselves in a way that cancer cells can’t. IG-IMRT is a type of targeted external beam radiation therapy.

These may be done on an x-ray machine called a simulator or on a CT scan machine. These scans are used only to map your treatment. They are not used for diagnosis or to find tumors. If you need other imaging, your nurse will explain this to you.
If you and your clinical team decide that radiation therapy is the best course of treatment, today’s innovative radiation treatments are precision guided to treat only the cancer and not the surrounding tissue. That’s one of the reasons why using IMRT and IGRT to treat prostate cancer is so effective.
Intensity-modulated radiation therapy (IMRT) is a type of external beam radiation therapy (EBRT) used to treat prostate cancer patients . IMRT is an advanced type of therapy that manipulates beams of radiation to conform to the tumor’s shape with the goal of reducing the exposure of the healthy tissues surrounding the cancer.
IGRT uses imaging tools such as an MRI (magnetic resonance imaging), CT or CAT scan (computed tomography), or PET scan (positron emission tomography) to safely and accurately deliver radiation treatment to the cancerous tumor with as little normal tissue being treated as clinically appropriate.
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.
IMRT, an advanced form of 3D-CRT therapy, is the most common type of external beam radiation therapy for prostate cancer. It uses a computer-driven machine that moves around the patient as it delivers radiation.
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.
Radiation therapy uses high-energy rays or particles to kill cancer cells. Depending on the stage of the prostate cancer and other factors, radiation therapy might be used: 1 As the first treatment for cancer that is still just in the prostate gland and is low grade. Cure rates for men with these types of cancers are about the same as those for men treated with radical prostatectomy. 2 As part of the first treatment (along with hormone therapy) for cancers that have grown outside the prostate gland and into nearby tissues. 3 If the cancer is not removed completely or comes back (recurs) in the area of the prostate after surgery. 4 If the cancer is advanced, to help keep the cancer under control for as long as possible and to help prevent or relieve symptoms.
