This review article focuses on prostate carcinoma and underscores changes in the prostate chapter as well as those made across the entire series of the 5th edition of WHO Blue Books. Evolving and unsettled issues related to grading of intraductal carcinoma of the prostate and reporting of tertiary Gleason pattern, the definition and prognostic significance of cribriform growth pattern, and molecular pathology of prostate cancer will also be covered in this review. The publication of WHO Classification of Urinary and Male Genital Tumors 5th Edition marks another major milestone in the field of genitourinary GU pathology and is the culmination of scientific advancements in recent years built upon the 4th edition published in The new edition of this authoritative reference book provides a comprehensive update on tumor classification in the same modular fashion as the previous edition with the addition of several new sections for each disease entity, including cytology, diagnostic molecular pathology, essential and desirable diagnostic criteria, and staging. This review article highlights salient changes made to the prostate chapter as we have gained better understanding of the etiology, pathogenesis, and molecular pathology of prostate cancer. The following topics will be presented in detail: 1 changes in nomenclature and terminology, 2 prostatic ductal adenocarcinoma and prostatic intraepithelial neoplasia PIN -like adenocarcinoma, 3 intraductal proliferative lesions and reporting recommendations from the two major urological societies regarding intraductal carcinoma of the prostate, 4 cribriform growth pattern, 5 reporting of tertiary Gleason pattern, 6 treatment-related neuroendocrine prostatic carcinoma, and 7 molecular genetics.

Four major pathologic entities will be discussed in this topic review: prostatic intraepithelial neoplasia PIN , atypical adenomatous hyperplasia AAH, also termed adenosis , atrophic lesions, and atypical small acinar proliferation ASAP. High-grade PIN is the most likely precursor of the majority of prostatic adenocarcinomas. In contrast, AAH and atrophic lesions are possible, although uncertain, precancerous lesions. ASAP is not a true biologic entity but is a diagnostic term in pathology when a lesion suspicious for but not diagnostic of carcinoma is identified. The pathologic characteristics, prevalence, relationship to prostate cancer, and clinical significance of these lesions are discussed in this topic, with a particular emphasis on PIN. Histology — The histologic characteristics of PIN have been well described [ 5,6 ]. The neoplastic prostatic epithelial cells are within prostatic ducts or acini, which are typically large and branched, with a convoluted inner contour similar to benign glands picture 1.

These assays can guide clinical decision making regarding active surveillance or indication of adjuvant therapy following radical prostatectomy.

The molecular events most commonly implicated in PCa initiation include MYC overexpression, inactivation of GSTP1 and other genes by promoter CpG island hypermethylation, and chromosomal structural alterations such as telomere shortening and ETS gene fusions 71 , J Clin Oncol ; 32 Other more subtle changes are the standardization of mitotic counts, genomic nomenclatures, and units of length. Accordingly, it is recommended to only grade the conventional PCa component in these tumors. Of note, none of the histologic patterns of HGPIN carries any clinical significance, and their designations should be avoided in routine practice High-grade prostatic intraepithelial neoplasia. Focal necrosis is also commonly present. PIN-like adenocarcinoma. Board review style answer 4. Prostate ; 78 Chromogranin , neuron specific enolase , synaptophysin. However, occasional studies have also found differing genomic profiles in ductal PCa, such as a lower rate of ERG fusion and expression 13 , 14 ; enrichment of germline or somatic alterations of genes related to DNA damage repair, including homologous recombination and mismatch repair genes 15 , 16 ; and a higher frequency of mutations in WNT signaling pathway activating CTNBB1 and inactivating APC mutations , which are often mutually exclusive with activating mutations in the PI3K signaling pathway 17 , Morphologic and clinical correlations.
