Hypofractionated Post-prostatectomy Radiotherapy (HYPORT)for Localized Prostate Cancer

Summary

The aim of this trial is to compare the safety outcomes of Hypofractionated postprostatectomy radiotherapy (HYPORT) and Conventionally fractionated postprostatectomy radiotherapy(COPORT) in treating patients with localized prostate cancer. Accumulating evidence has proven the safety and feasibility of HYPORT for localized prostate cancer.But for localized prostate cancer,the optimal dose per fraction of HYPORT is still on its way. It is not yet known whether giving HYPORT(57.5-65 Gy in 23-26 daily fractions of 2.5 Gy ) with or COPORT may work better in treating patients with prostate cancer.
