Defining the Most Informative Intermediate Clinical Endpoints for Predicting Overall Survival in Patients Treated with Radical Prostatectomy for High-risk Prostate Cancer

Clinical recurrence within 5 yr after surgery was the most informative endpoint in predicting long-term overall survival in surgically treated high-risk patients. In men with biochemical recurrence, clinical recurrence within the next 12 mo was the most informative intermediate clinical endpoint. These results should be taken into account for optimal follow-up schedules and for the design of future trials developed in the high-risk setting.
