Are TRUS-guided prostate biopsies in clinical practice robust enough to make a correct assessment of the surgical strategy in prostatectomies? Poor correlation between preoperative prostate biopsies and postoperative specimens

Figure 2. The proportion of deviations in localization and Gleason score.

Table 1. Characteristics and frequency of deviations on the post-operative PAD report that might have changed the pre-operative assessment of surgical strategy if known prior to surgery.

Type of deviation	Frequency (%)
Unknown tumour on contralateral side of Gleason 7 or higher	29% (28/98)
Higher Gleason on site of reported tumour (upgrade)	36% (64/178)
Reported tumour present on contralateral side as from Biopsy	40% (39/98)
Extracapsular presence of tumour (pT3)	62% (61/98)
