伴微乳头结构肺腺癌的病理和临床特征研究进展

Research progress on the pathological and clinical features of lung adenocarcinoma with a micropapillary pattern

2011年,国际肺癌研究协会(International Association for the Study of Lung Cancer,IASLC)、美国胸科学会(American thoracic society,ATS)和欧洲呼吸学会(European Respiratory Society,ERS)同时将微乳头结构(micropapillary pattern,MPP)为主型肺腺癌划分为一种独立的病理类型,并将其定义为微乳头型肺腺癌(micropapillary-predominant adenocarcinoma,MPA),其组织学特异性和临床特殊性受到了学者的广泛关注。伴微乳头结构肺腺癌(lung adenocarcinoma with a micropapillary pattern,MPPAC)常具有侵袭性强、转移率高、术后易复发等预后不良的生物学行为。目前,MPPAC的临床诊断有赖于术后病理组织学检查,但针对其病理学异质性、分子生物学特点、临床特征和预后等方面的系统性研究较少。本文对MPPAC的病理和临床特征相关研究进展作一综述。

In 2011,the International Association for the Study of Lung Cancer(IASLC),American Thoracic Society(ATS)and European Respiratory Society(ERS)simultaneously defined micropapillary pattern(MPP)-based lung adenocarcinoma as an independent pathological type:micropapillary-predominant adenocarcinoma(MPA).Its histological and clinical specificities have attracted broad attention from researchers.Lung adenocarcinoma with a micropapillary pattern(MPPAC)often shows biological behaviors indicative of poor prognosis,including strong invasion,high metastasis rate and easy recurrence after surgical treatment.At present,the clinical diagnosis of MPPAC depends on postoperative pathological examination,but systematic studies on its pathological heterogeneity,molecular biological characteristics,clinical features and prognosis remains scarce.This review aims to focus on the research progress of the pathological and clinical features of MPPAC.
