INDIVIDUALIZATION OF THE BIOPSY PROTOCOL ACCORDING TO THE PROSTATE GLAND VOLUME FOR PROSTATE CANCER DETECTION

The 10 core biopsy protocol must be used in all group of patients except patients with a prostate volume of 14.9 to 35 cc. In patients with a prostate volume of 14.9 to 35 cc the 8 core biopsy protocol consisting of the apex, mid gland, lateral mid gland and lateral base can be used since it revealed results similar to those of the 10 core biopsy protocol. The classic sextant biopsy protocol seemed inadequate for all prostate volumes. Patients with a larger prostate had lower cancer detection rates. Transrectal ultrasound directed lesion biopsies may be omitted when using 10 core biopsy protocols since the yield of these biopsies was less than 2%.
