Summary
Brief summary (as posted)
The purpose of this study is to compare toxicities between 2 external beam radiation fractionation schemes plus a brachytherapy boost for prostate cancer. Our current standard use a 2 Gy per fraction schedule which is compare to the experimental hypofractionated 3 Gy per day approach with neo adjuvant hormonal therapy. It will demonstrate the feasibility and safety of such a treatment regimen in prostate cancer. It may also set base for a larger randomized trial.
