Why Fusion biopsy

  • Prostate cancer can be hard to detect

  • The traditional digital rectal exam isn’t a very effective screening tool

  • The prostate specific antigen (PSA) blood test, since 1994 a companion to the digital rectal exam for screening older men, measures levels of a protein that often go up when prostate cancer is present

  • Drawbacks of random biopsy:

    • Numerous needles (about 12 to 24) into different prostate areas, guided by ultrasound.
    • The ultrasound images help placing the needles properly, but the pictures aren’t distinct enough to distinguish cancerous from normal prostate tissue

  • An MRI scan has a higher resolution than ultrasound images and reveals more details in soft tissue, such as the prostate gland

  • It is not yet scientifically approved that prostate cancer can be diagnosed from an MRI image, but it certainly can be used to identify suspicious areas

Prostate biopsy facts

The challenge: systematic TRUS biopsies show low CA-detection

  • TRUS random biopsy (12 cores) success rate: ~33%

  • TRUS saturation biopsy (30 cores) success rate: ~40%
