Are Biochemical Recurrence Outcomes Similar After Radical Prostatectomy and Radiation Therapy? Analysis of Prostate Cancer-Specific Mortality by Nomogram-predicted Risks of Biochemical Recurrence

摘要

Background: Due to the protracted natural history of the clinical progression of prostate cancer, biochemical recurrence (BCR) is often used to compare treatment modalities. However, BCR definitions and posttreatment prostate-specific antigen kinetics vary considerably among treatments, calling into the question the validity of such comparisons.
