Abstract
The aim of this study is to evaluate the role of an extensive “saturation biopsy” in patients at increased risk for prostate cancer with previously negative biopsies, HGPIN or ASAP diagnosis.
Materials and Methods
We performed an extensive 24 cores biopsy with spinal anaesthesia in 168 patients with at least 1 prior negative biopsy and persistently high PSA and/or abnormal digital rectal examination or with a ASAP or HGPIN diagnosis at previous biopsy.
Results
A total of 55 patients were diagnosed having prostate cancer for an overall diagnostic yeld of 33 %. Specifically, cancer was detected in 79% of ASAP, 32% of HGPIN and 28% of prior negative biopsies. 31 patients underwent radical retropubic prostatectomy. There was no correlation between number of positive biopsy cores and pathological stage or pathological Gleason score. A high concordance was found between clinical and pathological Gleason score.
Conclusions
Extensive biopsy can be considered a safe and effective diagnostic tool in men at risk for prostate cancer with previous negative biopsies. This procedure comes out to be particularly useful also in patients with a prior ASAP or HGPIN.
