Stereotactic Body Radiotherapy (SBRT) for Prostate Cancer (SMART)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00941915
Recruitment Status : Active, not recruiting

Duke University

Brief Summary:
The purpose of this study is to evaluate the incidence of urinary and gastrointestinal acute and late side effects in patients treated with stereotactic body radiotherapy (SBRT) to the prostate. Stereotactic radiation therapy is given as five treatments over a 2-3 week period. The prostate is localized and the plan is reoptimized as needed prior to each treatment.

Condition or disease Intervention/treatment Phase
Prostate Cancer Radiation: SBRT Prostate Not Applicable

Detailed Description:
This protocol requires radiation treatments to be performed with a stereotactic technique with the use of a 3-D coordinate system defined by implanted transponders (i.e. Calypso) or use of the ExacTrac system and/or use cone-beam CT (CBCT) with fiducial markers.
