Purpose Additive systematic biopsy (SB) contributes to prostate cancer (PCA) detection in MRI-targeted biopsy (TB).
However, the reasons for this are not yet clear.
We compared the performance of TB, SB and the combined approach (CB) in biopsy-naive men to determine the added value of SB for tumor grading and spatial tumor distribution.
Methods Two hundred and fifty-nine men with PI-RADS 3–5 graded lesions who underwent CB were enrolled.
Data were prospectively collected, and cancer detection rates (CDR) were compared at patient and lesion level.
Gleason grade up- and down-grading from biopsy to prostatectomy specimens ( n = 56; 21.6%) were determined.
Clinically significant cancer (csPCA) was defined as Gleason grade ≥ 2.
Results CDR by CB based on PI-RADS categories 3, 4 and 5 for PCA were 24%, 72% and 98% and 17%, 64% and 96% for csPCA.
CB detected more PCA and csPCA than TB ( p < 0.001).
However, TB showed higher efficiency, defined as CDR per biopsy core, for PCA and csPCA in PI-RADS 4–5 rated patients ( p < 0.001).
Concordance between biopsy and prostatectomy grading was highest in CB with misdiagnosis of csPCA in 25% of men.
TB missed cancer attributed to the index lesion in 10.2% and underestimated csPCA in 7%.
In these cases, 76% of csPCA were detected and 85% were upgraded to csPCA by SB in adjacent sectors.
Conclusion SB cannot be safely abundant without increased diagnostic uncertainty.
When TB missed csPCA, SB detected it close to the MRI-target lesion.
Therefore, perifocal biopsies could potentially replace 12-core SB with increased efficiency in taking manageable risks.
