Abstract
肺癌是全世界发病率最高的恶性肿瘤。目前,肺腺癌(lung adenocarcinoma, LUAD)是肺癌中最常见的组织学类型。然而,具有相同病理亚型的LUAD患者之间却存在显著的预后差异,导致该预后差异的主要原因之一是其组织学异质性。研究表明,除了2015年世界卫生组织(World Health Organization, WHO)对浸润性LUAD的5种主要生长方式的分类外,LUAD中还存在其他的组织学结构并影响其临床预后。其中,筛状成分(cribriform component, CC)是当前LUAD病理组织学的研究热点之一。已有研究表明,CC的有无可进一步预测LUAD患者的预后。随着相关研究逐渐深入,CC与LUAD各组织学类型、临床病理因素、生存预后等方面的关联尚存在争议。本文综合论述了CC在LUAD中的研究进展。
