Summary
Brief summary (as posted)
The first technology is called high dose rate brachytherapy. Brachytherapy is sometimes called internal radiation therapy. High dose rate brachytherapy is a procedure that involves temporarily placing radioactive material inside the patient's body for about 10-20 minutes. Then, the remainder of the radiation treatment will be given over a 3 week period using stereotactic body radiation therapy (SBRT). SBRT is a novel treatment modality that involves the delivery of very high individual doses of radiation to tumors with high precision. This allows the doctor to deliver the same amount of radiation in a much shorter time. The purpose of this study is to determine the safety of brachytherapy when combined with hypofractionated SBRT.
