ReviewIndividualization of Adjuvant Therapy After Radical Prostatectomy for Clinically Localized Prostate Cancer: Current Status and Future Directions

Radiation therapy indications in the postprostatectomy setting are evolving. Several retrospective series have identified a number of “high-risk” pathologic features associated with an elevated risk of disease recurrence after radical prostatectomy. More recently, several randomized phase III trials demonstrated superior biochemical relapse-free survival for adjuvant radiation therapy after prostatectomy for patients with these high-risk pathologic features, including positive margin status, extraprostatic extension, and/or seminal vesicle invasion. These series further suggested improvement in distant metastasis control and overall survival after 15 years. However, not all patients with high-risk features experience disease recurrence after surgery alone, and some subsets of patients experience suboptimal disease control and survival despite immediate postoperative radiotherapy. Furthermore, some patients without high-risk features will develop recurrence. The present review discusses the current data and potential future directions to improve individualization of therapy after prostatectomy.
