BackgroundCribriform (CBFM) pattern on prostate biopsy has been implicated as a predictor for high‐risk features, potentially leading to adverse outcomes after definitive treatment. This study aims to investigate whether the CBFM pattern containing prostate cancers (PCa) were associated with false negative magnetic resonance imaging (MRI) and determine the association between MRI and histopathological disease burden.MethodsPatients who underwent multiparametric magnetic resonance imaging (mpMRI), combined 12‐core transrectal ultrasound (TRUS) guided systematic (SB) and MRI/US fusion‐guided biopsy were retrospectively queried for the presence of CBFM pattern at biopsy. Biopsy cores and lesions were categorized as follows: C0 = benign, C1 = PCa with no CBFM pattern, C2 = PCa with CBFM pattern. Correlation between cancer core length (CCL) and measured MRI lesion dimension were assessed using a modified Pearson correlation test for clustered data. Differences between the biopsy core groups were assessed with the Wilcoxon‐signed rank test with clustering.ResultsBetween 2015 and 2022, a total of 131 consecutive patients with CBFM pattern on prostate biopsy and pre‐biopsy mpMRI were included. Clinical feature analysis included 1572 systematic biopsy cores (1149 C0, 272 C1, 151 C2) and 736 MRI‐targeted biopsy cores (253 C0, 272 C1, 211 C2). Of the 131 patients with confirmed CBFM pathology, targeted biopsy (TBx) alone identified CBFM in 76.3% (100/131) of patients and detected PCa in 97.7% (128/131) patients. SBx biopsy alone detected CBFM in 61.1% (80/131) of patients and PCa in 90.8% (119/131) patients. TBx and SBx had equivalent detection in patients with smaller prostates (p= 0.045). For both PCa lesion groups there was a positive and significant correlation between maximum MRI lesion dimension and CCL (C1 lesions:p< 0.01, C2 lesions:p< 0.001). There was a significant difference in CCL between C1 and C2 lesions for T2 scores of 3 and 5 (p≤ 0.01,p≤ 0.01, respectively) and PI‐RADS 5 lesions (p≤ 0.01), with C2 lesions having larger CCL, despite no significant difference in MRI lesion dimension.ConclusionsThe extent of disease for CBFM‐containing tumors is difficult to capture on mpMRI. When comparing MRI lesions of similar dimensions and PIRADS scores, CBFM‐containing tumors appear to have larger cancer yield on biopsy. Proper staging and planning of therapeutic interventions is reliant on accurate mpMRI estimation. Special considerations should be taken for patients with CBFM pattern on prostate biopsy.
