Single Fraction HDR Brachytherapy Plus Hypofractionated EBRT for Low-risk Prostate Cancer: Phase II Trial

The hypofractionated external radiation (EBRT) is a technique that radiation dose delivery using higher daily fractions than those used routinely. In this way can cause more damage tumor, especially in tissues that have a slower proliferation rate, as in the case of prostate cancer. Furthermore, achieves a reduction in total treatment time and probably a lesser chance of development of collateral in tissues of high multiplication rate as the lining of the rectum and bladder effects. With brachytherapy boost for high dose rate is achieved by administering a more intense dose on the tumor and lower the sound around the region to be treated tissues, improving the therapeutic window. Treatment with retracted and fully ambulatory time, has potential benefit as early patient return to usual activities and optimizing the flow of patients who require treatment with radiotherapy. This prospective study aims to assess the results and the toxicity profile of this treatment regimen retracted.
