INTRODUCTION: There is now increased understanding that invasive cribriform carcinoma is a relatively aggressive disease. In some recent publications, the recommendation is that all cribriform patterns be classified as Gleason pattern (GP) 4 rather than GP 3.
MATERIALS AND METHODS: We assessed the cribriform foci (CF) associated with the more definitive patterns 3, 4, and 5 elsewhere on the 185 radical prostatectomy specimens and evaluated the association of the cribriform pattern with extraprostatic extension, surgical margin.
RESULTS: CF were more frequently observed in cases with definitive patterns 4 and 5 than in cases with pattern 3 (all cases with pattern 5 exhibited CF). Cases with Gleason score 3+3 and CF were more frequently associated with extraprostatic extension, and a positive surgical margin.
CONCLUSIONS: Our results demonstrate that diagnosing all cribriform patterns as at least GP 4 would significantly affect further therapeutic options and prognosis. However, as many of these modifications are empirical and supported by only a few studies, long-term follow-up studies with clinical endpoints are necessary to validate these recommendations.
