Advanced Biopsy Techniques

The routine sextant biopsy, perhaps appropriate for men with tPSA of 4ng/mL and abnormal DRE, yields a 72.6% to 80% cancer detection rate. However, as prostate cancer is becoming more difficult to detect, urologists are considering strategies outside the routine sextant biopsy to help locate tumors that might otherwise be missed. Below are revolutionary techniques from urologists that highlight some of these strategies.

The routine sextant plus additional cores and configurations:

Core Biopsy Diagrams

8 Core

95% cancer detection rate

By replacing base core samplings from the routine sextant with four biopsies from the lateral peripheral zones, the cancer detection rises from 80% for the routine sextant to 95% for the 8-core biopsy.

10 Core

96% cancer detection rate

By replacing 2 base core samplings from the routine sextant with 4 biopsies from the lateral peripheral zones, the cancer detection rate rises from 80% to 95%.

10 Core

99% cancer detection rate

By extracting lateral biopsies from the mid and apical zones in addition to the routine sextant, the cancer detection rate rises from 80% to 99%.
