The UCSF Cancer of the Prostate Risk Assessment score, abbreviated as UCSF-CAPRA score, is a clinical calculator used in the management of prostate cancer. This scoring system is applicable to patients diagnosed with prostate cancer and is used to predict the risk of recurrence after radical prostatectomy. The UCSF-CAPRA score takes into account factors such as the patient's age, prostate-specific antigen (PSA) level, Gleason score, percentage of biopsy cores positive for cancer, and clinical T stage. The clinical utility of the UCSF-CAPRA score lies in its ability to guide treatment decisions by stratifying patients into low, intermediate, and high-risk groups. It can also be used to predict the 10-year probability of prostate cancer mortality. There are no specific exclusion criteria for the use of the UCSF-CAPRA score. However, it is less applicable to patients who have already undergone treatment for prostate cancer, such as radiation therapy or hormone therapy, as these treatments can alter the parameters used in the score calculation.
