Radiation Therapy

TUCC is one of the only centers in the U.S. to offer on site, comprehensive radiation therapy for urologic cancers. Our radiation oncologist, Eric Gross, M.D. is board certified in radiation oncology and highly trained in the delivery of radiation to treat urologic cancers. He is the only radiation oncologist in Colorado whose practice is devoted solely to the delivery of radiation therapy for the treatment of urologic cancers.

As of January 2016, TUCC is treating our radiation oncology patients on the Elekta Versa HD linear accelerator. Versa HD safely delivers radiation beams through conventional techniques, including intensity modulated radiation therapy and image-guided radiation therapy, as well as more advanced volumetric arc therapy (VMAT) and stereotactic body radiotherapy (SBRT). 

Versa HD is specially designed to visualize and track the target cancer site and surrounding critical structures, which helps minimizes the risk of side effects. The system will allow TUCC to deliver the most advanced radiation therapy techniques while setting the standard in patient safety. 
 

Types of Radiation Therapy

 

External Beam Radiation Therapy

External beam radiation therapy utilizes a linear accelerator to generate a beam of radiation that is directed toward the desired treatment area.

Treatment planning and delivery techniques such as 3-D conformal planning and intensity modulated radiation therapy (IMRT), can be utilized to conform the dose of radiation to the planned treatment area. This allows higher doses to be administered to desired treatment areas and reduces the risk of exposure to surrounding normal tissues. Both techniques allow for better control of the radiation beam to the tumor with reduced side effects.

TUCC also offers patients a more advanced form of IMRT, volumetric arc therapy (VMAT), on the Versa HD. With conventional IMRT, the linear accelerator must rotate around the patient a few times to treat the cancerous tumor from several different angles. In contrast, VMAT delivers the radiation dose to the entire tumor in a 360-degree rotation within minutes. 

The prostate can change position depending on the volumes of the bladder and rectum. With image guided radiation therapy (IGRT), metallic markers are inserted into the prostate so that their position can be visualized on a daily basis. Daily assessment of the markers and subsequent adjustments enable therapists to deliver more accurate radiation treatments. This reduces the risk of radiation exposure to normal tissues and side effects.

 

Brachytherapy

Brachytherapy is a form of radiation therapy administered over a short distance. In select prostate cancer patients, radioactive seeds may be implanted into the prostate. As they decay, radiation is released. The radiation dose is determined by the seed characteristics, the number of seeds implanted and the distribution of the seeds. The seeds remain in the prostate after the radiation dose is released. A combination of brachytherapy and external beam radiation therapy may be used in select patients.

 

Stereotactic Body Radiotherapy

SBRT is an ultra-high dose and precise form of radiation therapy used to eliminate prostate and kidney tumors. This type of treatment is known as hypofractionated radiation therapy, which delivers higher doses of radiation in a more targeted fashion over fewer treatments. Shortened treatment times can improve patient comfort, particularly for older patients who may find it difficult to remain in one position over extended periods of time. The risk of movement by patients who are receiving treatment near important structures is minimized, as well. TUCC is pioneering the use of SBRT in Colorado on the Versa HD.
