乳腺癌分子分类临床病理745例分析

目的:探讨乳腺癌分子分类及其各种亚型的临床病理学特征。方法:回顾性分析既往研究中曾用免疫组织化学S-P法检测浸润性乳腺癌中癌细胞表达雌激素受体、孕激素受体和表皮生长因子受体蛋白表达的病例,按照分子分类的标准重新分类,观察各种亚型的临床病理学特点,并与WHO组织学分类相比较。结果:将符合标准的745例浸润性乳腺癌分为5种分子亚型:管腔A型235例,管腔B型95例,表皮生长因子受体过表达型141例,基底细胞样型/三阴性型142例,其余132例未确定分类。描述各亚型临床病理特点。结论:乳腺癌的分子分类与WHO组织学分类间有一定对应关系。免疫组织化学标记有助于分子分类,分子分类亚型对于治疗和预后具有更直接的关系,值得进一步推广应用和标准化。

Molecular classification in breast cancer:a clinicopathological analysis of 745 cases

Objective:To explore the molecular classification in breast cancer and the clinicopathological features of variant subtypes.Methods:The expression of ER,PR and HER2(C-erbB-2) in the cases of breast cancer detected immunohistochemically(S-P method) were studied retrospectively.The cases were reclassified according to the standard of molecular classification,and the clinicopathological features were observed and compared with the WHO histological classification.Results:The invasive breast carcinomas 745 cases...
