BACKGROUND: Histopathological discrepancies between biopsy and radical prostatectomy (RP) specimens may lead to unnecessary, excessive, or incomplete treatment in prostate cancer (PCa) patients.
OBJECTIVES: To compare the upgrading rates of International Society of Urological Pathology (ISUP) grades and tumor laterality in patients that underwent standard 12-core transrectal ultrasound-guided standard prostate biopsy (SPB) versus multiparametric magnetic resonance-guided fusion prostate biopsy (FPB) for PCa.
METHODS: This retrospective study included 152 patients that underwent prostate biopsy and RP in our clinic. The patients were divided into 2 groups: Group A (n = 90) included patients that underwent SPB and Group B (n = 62) included patients that underwent FPB (targeted biopsy + standard biopsy). Upgrading of ISUP grades, tumor laterality, and upgrading of tumor laterality were compared between the 2 groups. Upgrading of tumor laterality defined as detection of tumor at both lobes in RP pathology while it was at unilateral lobe in biopsy pathology.
RESULTS: ISUP grade 1 was the most common histopathology in both groups. The ISUP upgrading rate on final pathology was significantly lower in the FPB group compared to the SPB group (22.7 vs. 37.7%; p < 0.048). Similarly, the upgrading rate of tumor laterality was lower in the FPB group compared to the SPB group (37.7 vs. 9.7%; p < 0.001).
CONCLUSION: The results suggested that FPB can provide more accurate results compared to SPB.
