前列腺腺癌尤其是高分化腺癌与中 -重度前列腺上皮内瘤的鉴别十分重要 ,因为它们的治疗原则及预后均有根本不同。在HE染色的切片上 ,从结构到细胞形态都难以明确区分 ,其中高分化前列腺腺癌的细胞异型性与其他组织来源的癌细胞异型性相比不十分显著 ,浸润性生长亦不易观察 ,故 Prostate adenocarcinoma, especially well-differentiated adenocarcinoma, is associated with the diagnosis of moderate-severe prostate intraepithelial neoplasia because of the fundamentally different treatment principles and prognosis. In the HE-stained sections, from the structure to the cell morphology are difficult to distinguish between the well-differentiated prostate adenocarcinoma cell atypia and other tissue-derived cancer atypia is not very significant, invasive growth is not easy to observe, so
