LONG-TERM RESULTS OF RADIATION THERAPY FOR PROSTATE CANCER RECURRENCE FOLLOWING RADICAL PROSTATECTOMY

Abstract

Patients with Gleason score 8 or greater, positive seminal vesicles or lymph nodes, or a PSA recurrence within the first year following surgery rarely benefit from radiation therapy. As the interval to PSA recurrence increases, the likelihood of responding to radiation therapy increases substantially. These parameters are useful in the selection of patients with prostate cancer recurrences who are likely to benefit from radiation to the prostatic bed.
