When is a prostate biopsy needed?
Elevated PSA levels or abnormalities detected during palpation may lead physicians to suspect prostate cancer. If this is the case, a prostate biopsy – i.e. the collection of tissue samples from the prostate – will be needed. Regular biopsies are also performed as a part of the active surveillance approach to less aggressive prostate cancers.
What is the difference between a traditional prostate biopsy and a fusion biopsy?
In a traditional biopsy, around 12 to 18 samples are taken transrectally, with the help of ultrasound monitoring and typically under local anaesthesia. Since ultrasound images are not distinct enough to identify suspicious areas in the prostate with certainty, samples are collected systematically but not from specific areas. In contrast, a fusion biopsy begins with a high-resolution MRI of the prostate, which allows suspicious areas to be identified with a high degree of certainty. Targeted samples of these suspicious areas are then taken.
What is the procedure for a fusion biopsy of the prostate?
At alta uro, fusion biopsies of the prostate are performed through the perineum while the patient is briefly anaesthetised. This approach allows us to accurately reach all areas of the prostate. Compared to a transrectal biopsy, the risk of infection is minimal. State-of-the-art computer technology is used to superimpose the images taken during the MRI over ultrasound images of the prostate in real time, making it possible to take targeted samples.
What are the advantages of a fusion biopsy?
Fusion biopsies of the prostate offer numerous advantages that we believe are invaluable for our patients. These include:
- Detection of tumours that could be missed by traditional biopsies
- Targeted biopsies of suspicious areas
- Avoidance of unnecessary biopsies
- Minimisation of the risk of inflammation
