In 46 radical prostatectomy specimens, carcinoma volume and Gleason histologic grade were compared among 21 cancers containing Grade 3 cribriform areas and 25 noncribriform carcinomas. A large body of evidence has shown that pattern 4 cribriform PCa (especially non-glomeruloid type) is associated with adverse pathologic features and clinical outcomes compared with non-cribriform pattern 4 PCa. The distinction between cribriform Gleason pattern 3 and 4 prostate cancer is controversial. IDC features were identified in 36.2% of gBRCA2 patients and 50% of non-gBRCA2 carriers. The aim of this review is to describe the role of cribriform growth in prostate cancer with respect to diagnosis, prognosis and molecular pathology. Recently, percent Gleason pattern 4 and presence of invasive cribriform and/or intraductal carcinoma (CR/IDC) have been recognized for their independent predictive value for prostate cancer outcome. Mod Pathol. Would you like email updates of new search results? Improving risk assessment in this group is of particular interest, as Gleason score 7 prostate cancer on biopsy is an important clinical threshold for active treatment. Architecturally, four Gleason grade 4 growth patterns are recognized: ill-formed, fused, glomeruloid and cribriform. One of the major implications of the cribriform growth is that it precludes a patient from choosing active surveillance. Prostate cancer with cribriform architecture is now rarely considered representative of Gleason pattern 3 or a lower pattern.
