The combined clinical cell-cycle risk (CCR) score uses clinical and genetic factors to assess the risk of metastasis after radiation therapy in patients with prostate cancer. The CCR score has proven accurate in studies and can guide post-radiation treatment decisions in practice, according to Jonathan D. Tward, MD, PhD, of the University of Utah, Salt Lake City. Dr. Tward discusses the CCR score with host David Henry, MD, in this episode. About the score The CCR score combines the cell-cycle progression (CCP) score (available commercially as the Prolaris test) and the Cancer of the Prostate Risk Assessment (CAPRA) score to more precisely determine the postradiation risk for metastatic disease. Investigators identified a threshold for determining precise risk levels (2.112), which allows for personalized treatment decision-making based on more individual characteristics than standard risk-group categorizations, according to Dr. Tward. He noted that standard risk groups can include a...
