OBJECTIVE
UroNav MRI/TRUS biopsy offers a more accurate test result regarding prostate cancer. The goal of the UroNav is to find more transitional zone prostate cancers that a standard mapping biopsy is unable to see. This paper aims to evaluate the utility of UroNav MRI/TRUS biopsy to detect clinically significant transition zone cancers in patients on active surveillance with low volume, low grade cancer.
METHODS
We retrospectively analyzed 268 prostate cancer patients from Minnesota Urology over a threeyear period who underwent a UroNav (MRI/TRUS) biopsy as part of standardized follow up in an active surveillance protocol. All patients underwent both biopsy of MRI PiRAD lesions and a standard mapping biopsy at the time of procedure. Patients with positive PiRAD transition zone and negative mapping biopsies were identified. Kaplan-Meier, Cox Proportional Hazards test, ANOVA and Chi-Square tests were performed. Data was analyzed using IBM SPSS version 27 and statistical significance was set at α=0.05.
RESULTS
Of the 268 patients, 68 (25%) of the patients had a normal standard mapping prostate biopsies. Using UroNav technology cancer was found showing a statistically significant amount of prostate cancer in the transitional zone missed by standard mapping biopsy (P value <0.05) Out of these 68 patients 35 (51.5%) were reported to have a Gleason score ≥7 indicating clinically significant prostate cancer.
CONCLUSIONS
The use of UroNav MRI/TRUS fusion biopsy allowed detection of clinically significant transition zone cancer missed by concurrent standard mapping biopsies in an active surveillance population. This should be continually explored to get a larger sample size to see if the UroNav can also detect missed clinically significant prostate cancer at a high rate.
