PSA Bounce After Dose-Escalated External Beam Radiation Therapy Is an Independent Predictor of PSA Recurrence, Metastasis, and Survival in Prostate Adenocarcinoma Patients

In a cohort of 1898 patients treated with a uniform external-beam radiation therapy treatment approach for prostate cancer, prostate-specific antigen (PSA) fluctuations were carefully evaluated to determine their impact on long-term survival outcomes. Multivariate analysis demonstrated that the occurrence of a PSA bounce in the follow-up period predicted for reduced PSA recurrences, decreased incidence of distant metastases, and improved cause-specific and overall survival outcomes.
