The Number of Cores Taken in Patients Diagnosed with a Single Microfocus at Initial Biopsy is a Major Predictor of Insignificant Prostate Cancer

Of patients diagnosed with a single microfocus of prostate cancer the number of biopsy cores taken was a major independent predictor of having pathologically confirmed insignificant prostate cancer at radical prostatectomy. Therefore, when active surveillance is considered as a possible alternative in patients with microfocus of prostate cancer, the number of cores taken should be taken into account in decision making.
