To report the outcome and morbidity data for patients treated with post-prostatectomy radiotherapy (PPRT) in a multicenter collaboration.

The case records of all patients treated with PPRT from 1996 to 1998 were reviewed. Survival was calculated using Kaplan-Meier methods. Potential prognostic factors were evaluated using the Cox proportional hazards regression model. Prostate-specific antigen (PSA) remission was defined as a PSA level of 0.2 ng/mL or less. Acute and late morbidities were documented.

We reviewed the data of 115 patients, with a median follow-up from the start of PPRT of 28.7 months. Patients were treated with adjuvant intent (n = 23), for local recurrence (n = 27), or for a detectable PSA level (n = 65). The overall and cause-specific survival rate at 5 years was 73.7% and 81.4%, respectively. The biochemical disease-free survival rate was 69.6% at 2 years and 50% at 5 years. Factors predicting for subsequent relapse on multivariate analysis were pre-PPRT PSA (P = 0.013) and post-PPRT nadir (P <0.0001). Patients with a PSA greater than 1 ng/mL fared significantly worse than those with lower levels (P <0.0001). For patients with a pretreatment PSA of less than 1 ng/mL and an operative Gleason score of 7 or less, the 5-year projected biochemical disease-free survival rate was 71%. One case of grade 3 late proctitis was recorded, and 4 patients had continued grade 3 late urinary incontinence.

Early use of PPRT is effective and well tolerated in patients at risk of, or with proven, local recurrence.
