Dr. Robert Timmerman and radiation therapist, Sheree Kincaid, get patient Breihan Bridgewater ready for treatment.

Dr. Timmerman is leading a national clinical trial testing the effectiveness of stereotactic body radiation therapy (SBRT) to treat prostate cancer in five, 30-minute sessions.
The SBRT technique is a relatively new procedure used for treating localized tumors by delivering very high doses of focused radiation.Dr. Timmerman has successfully used the technique to treat patients with lung and liver cancers.
"There are a number of good treatments for prostate cancer, but they all have some drawbacks - they're inconvenient; they're invasive; or they cause impotence, rectal injury or urinary incontinence," said Dr. Timmerman.

"This new treatment mimics the dose deposition of brachytherapy, but it is done noninvasively, in an outpatient setting, without making any incisions, needle punctures or anesthesia," Dr. Timmerman said."The beauty of it is that the patient only has to come in for five outpatient treatments and is finished in a week and a half."
Dr. Timmerman has treated 11 patients at UT Southwestern using this new method with only minor side effects.As part of the study, he is trying to establish the treatment's proper dose protocol.He also is establishing study sites at the University of Minnesota, University of Colorado and at a rural practice in South Dakota.
Health-care experts predict that about 218,000 new cases of prostate cancer will be diagnosed in the U.S. this year, and more than 27,000 men will die from the disease.
Dr. Timmerman said the SBRT treatment might be ideal for people who live far away from an academic medical center or who can't stay away from their jobs for extended periods of time to receive treatment or recover.
"We're targeting this population because they clearly need a better treatment," Dr. Timmerman said.
...
"Actually, we are seeing that the PSA levels in patients undergoing this new therapy are declining more rapidly than one would expect with conventional treatment," Dr. Timmerman said.
