ABSTRACT
PURPOSE:
The systematic routine sextant biopsy technique has been widely used in diagnosing prostatic cancer. But this technique may not include an adequate sampling of the prostate. We conducted a prospective study to evaluate the efficacy of the routine sextant prostate biopsy plus selective lesion-directed prostate biopsy method. MATERIALS ANDMETHODS:
120 men with abnormal digital rectal examination (DRE) and/or prostate-specific antigen (PSA) > or = 4.0ng/ml underwent a total of 122 routine sextant prostate biopsy (RSB) only or RSB plus selective lesion-directed prostate biopsy (SLB). SLB included one of the followings digital-guided biopsy, hypoechoic lesion-directed biopsy or transitional zone biopsy if there were palpable nodule on DRE, hypoechoic lesion on transrectal ultrasonography (TRUS), or previous history of negative biopsy, respectively.RESULTS:
The mean age of patients was 67.6 years (43-86) and the mean PSA level was 7.63ng/ml (0.47-over 155). 37.7% had cancer detected on biopsy. Detection rate in RSB plus SLB group (53.6%, 30 of 56) was higher than in RSB group (24.2%, 16 of 66). In RSB plus SLB group, 4 had cancer detected in SLB core(s) only. The positive rate of biopsy core was higher in the SLB core (72.9% (35/48)) than in the RSB core (54.4% (98/180)) (p= 0.022).CONCLUSIONS:
In the presence of a suspicious lesion or the history of a previously negative biopsy, the addition of SLB or transitional zone biopsy may increase the detection rate of prostatic cancer.
