Abstract
Purpose: To evaluate the clinical usefulness of the Seoul National University Prostate Cancer Risk Calculator (SNU-PCRC) to reduce unnecessary prostate biopsy and to increase the detection rate of high-risk cancer.
Materials and Methods: We retrospectively analyzed 546 patients who underwent prostate biopsy between 2014 and 2016. The subjects were divided into 2 groups based on the type of risk calculator used: conventional and SNU-PCRC group. In the SNU-PCRC group, prostate biopsy was recommended when the probability of SNU-PCRC was more than 30%.
Results: The SNU-PCRC group had significantly smaller prostate volume (p=0.010) and significantly more digital rectal examination and transrectal ultrasonography (TRUS) abnormalities (p=0.011 and p=0.010, respectively). Overall detection (71.9% vs. 32.1%) and high-risk cancer detection rates (40.6% vs. 19.3%) were significantly higher in the gray zone (prostate-specific antigen=4?10 ng/mL) (p<0.001 and p?0.006). The group with prostate cancer risk ≥30% on the SNU-PCRC compared to <30% group, overall detection rate of 72.3% versus 30.2% and high-risk detection rate of 60.6% versus 18.3% were significantly different (p<0.001 and p<0.001). Applying the SNU-PCRC to the conventional group could avoid unnecessary prostate biopsy in 50.6%.
Conclusions: SNU-PCRC is clinically useful to reduce unnecessary prostate biopsy and increase overall detection rate and high-risk cancer detection rate.
