Primary Pulmonary Lymphoepithelial Carcinoma (PLEC) is a rare subtype of non-small cell lung cancer (NSCLC) that exhibits a strong association with Epstein-Barr virus (EBV) infection and shows distinctive geographic and ethnic predilections. Over the past decades, significant efforts have been made to elucidate the pathogenic mechanisms of PLEC, and progress in diagnosis, treatment, and disease monitoring has been achieved. This review focuses on EBV-driven oncogenic mechanisms in PLEC and explores the relationship between EBV infection, tumor progression, and clinical prognosis. We further summarize the molecular pathology, tumor immune microenvironment, and clinicopathological characteristics of PLEC. These insights may offer a theoretical foundation for EBV-targeted and immunotherapeutic strategies in PLEC.
原发性肺淋巴上皮癌(PLEC)是非小细胞肺癌(NSCLC)的一种罕见亚型,与爱泼斯坦-巴尔病毒(EBV)感染密切相关,具有独特的地理和种族倾向。在过去几十年中,人们为阐明PLEC的致病机制做出了巨大努力,并在诊断、治疗和疾病监测方面取得了进展。本综述聚焦于EBV驱动的PLEC致癌机制,探讨EBV感染、肿瘤进展和临床预后之间的关系。我们还总结了PLEC的分子病理学、肿瘤免疫微环境和临床病理特征。这些见解可能为PLEC的EBV靶向治疗和免疫治疗策略提供理论基础。
