Evolution of prostate biopsy techniques. Looking back on a meaningful journey.
BACKGROUND
The technique of prostate biopsy has evolved a long way since its inception to being a safe diagnostic procedure. The principles of the biopsy technique continue to improvise with the knowledge about prostate cancer and availability of newer treatment options like active surveillance and focal therapy. Currently, we depend on accurate cancer information from the biopsy more than ever for deciding the ideal treatment option.


OBJECTIVE
The aim of this review is to present the major milestones in prostate biopsy technique evolutions and its impact on the prostate cancer management.


METHODS
We performed a detailed non-systematic literature review to present the historical facts on the transformations in prostate biopsy techniques and also the direction of present research to improve accurate cancer detection.


METHODS
There is a clear change in trend in biopsy technique before and after the introduction of transrectal ultrasound and prostate specific antigen. In the earlier era, the biopsies were aimed at palpable nodules and obtaining adequate prostatic tissue for diagnosis while the later era has moved towards detection of non-palpable and early prostate cancer. Recently, there is an increasing trend towards image guided targeted biopsies to extract maximum cancer information from minimum biopsy cores.


CONCLUSIONS
Prostate biopsy techniques have seen major changes since its inception and have a major impact on prostate cancer management. There is a great potential for research which can further support the newer treatment options like focal therapy.
