A Phase II Randomized Trial: ALTERNATE DAY ULTRAHYPOFRACTIONATED OR DAILY MODERATELY HYPOFRACTIONATED POST OPERATIVE RADIOTHERAPY
This is a multi-institution, randomized, non-inferiority Phase II trial comparing external beam radiotherapy delivered as 54 Gy in 20 fractions to prostate bed +/- 44 Gy in 20 fractions to pelvic lymph nodes delivered daily with external beam radiotherapy delivered as 30 Gy in 5 fractions to prostate bed +/- 25 Gy in 5 fractions to pelvic lymph nodes delivered on alternate days.
Inclusion: Age >/= 18 years; Able to provide informed consent; Histologic diagnosis of prostate adenocarcinoma; ECOG performance status 0-1; Previous radical prostatectomy > 6 months prior to radiotherapy start date; Planned to receive post-operative radiation.
Exclusion: Prior pelvic radiotherapy; Contraindications to radiotherapy; Participants with visible disease in the prostate bed or pelvic lymph nodes on imaging are not eligible for treatment on study; Confirmed metastases (if scan has been done for clinical care).
