Abstract
OBJECTIVE
To assess if a less extended biopsy in the transperineal approach is sufficient for detection of prostate cancer (PC) in patients with hypoechoic lesions.
METHODS
This was a prospective study of 167 consecutive patients with prostate hypoechoic lesion and who underwent transperineal ultrasound (TPUS)-guided 12-core and hypoechoic lesion core biopsy between January 2012 and February 2013.
RESULTS
PC was detected in 64.1% (107/167) of patients. The PC detection rate of the 12-core prostate biopsy scheme was the highest, but when including the hypoechoic lesion core, there was no difference between the 6- and 12-core schemes (all p > 0.05), irrespective of prostate volume or prostate-specific antigen levels (all p > 0.05).
CONCLUSIONS
A more limited biopsy scheme could be sufficient for the detection of PC if the hypoechoic lesion is sampled.
