IMRT-IGRT

Recent advances in technology have allowed physicians to develop a sophisticated radiation technique called: IMRT-IGRT, which stands for Intensity Modulated Radiation Therapy - Image Guided Radiation Therapy.

In the past, non image guided 3-D conformal radiation treatments were the standard for radiation treatments to the prostate, but IMRT-IGRT allows your Oncologist to deliver X-ray treatments to the prostate that account for the natural motion of the prostate therefore, reducing the amount of surrounding tissues being radiated.

Intensity Modulated Radiation Therapy (IMRT) is a relatively recently developed technique to improve the delivery of radiation therapy by the linear accelerator. Instead of maintaining a uniform radiation beam as used in conventional or 3 dimensional radiotherapy, IMRT uses devices within the machine to divide the radiation beam into multiple smaller beams called beamlets that can have di erent intensities (modulated) within the area being treated. This allows more precise adjustment of radiation doses to the tissues within the target area allowing increased dose to the prostate while relatively sparing the surrounding bladder and rectum. This is important, as several recent medical studies have suggested that higher prostate doses are associated with increased curability.

Urology Clinics of North Texas is proud to o er this novel technique as a therapeutic option to patients with cancer of the prostate. A dedicated team consisting of Radiation Oncologist, Physicist, Therapists and Nurses, will be here to help you as you go through this di cult step in life.

Our approach is to care for the patient as a person not another statistic. Our team is always praised for its candor, friendliness and comforting manners.

How is the treatment delivered?

The Prostate can change position inside the pelvis from day to day. IMRT – IGRT is able to aim the radiation to the prostate on a daily basis. A linear accelerator generates the x-rays used for IMRT – IGRT.

The daily treatments are provided at our state of the art facility conveniently located in Dallas, Texas.

Who is a good candidate?

Patients with no evidence of metastasis and even locally advanced tumors are good candidates for radiation treatments with curative intent. As with any other procedure, there are a few contraindications, like previous radiation to the pelvis and autoimmune diseases.

Are there any side effects?

The tissue-sparing capability of IMRT – IGRT radiation treatments have decreased the incidence of side e ects that were seen commonly in the past with the use of older radiation techniques.

Fatigue, frequency of urination, urgency, discomfort while urinating, diarrhea and loose stools vary from patient to patient. These symptoms are generally temporary and resolve after the radiation treatments are nished.
