The Role of Radiotherapy After Radical Prostatectomy in Patients with Prostate Cancer.

A non-negligible proportion of prostate cancer (PCa) patients undergoing radical prostatectomy (RP) harbors aggressive disease. These individuals are at higher risk of experiencing recurrence after surgery.

Results from prospective, randomized trials support the efficacy of adjuvant radiotherapy (aRT) on cancer control in selected patients with adverse disease features at RP. However, only one of these randomized trials found a significant benefit of aRT on survival. Although such a level of evidence is not currently available for salvage RT, retrospective studies demonstrated that this approach leads to excellent outcomes if administered at the earliest sign of PSA recurrence. Prognostic models might help clinicians in identifying patients who would benefit the most from adjuvant and/or salvage RT. This individualized approach would allow sparing the risk of short- and long-term toxicity in a substantial proportion of patients. Nonetheless, results from randomized trials are still awaited to compare the efficacy of (early) salvage and aRT.
