Prostate Biopsy Patterns in the CaPSURE Database: Evolution With Time and Impact on Outcome After Prostatectomy

The percent of positive cores is an independent predictor of disease recurrence after radical prostatectomy. The total number of tissue cores sampled increased during the last decade, thereby driving down the mean percent of positive cores from 42.6% to 32.1%. The trend toward an increasing number of removed cores may have contributed indirectly to improved outcomes after radical prostatectomy in the last decade.
