Intraoperative pleural lavage cytology is a diagnostic technique used to detect tumor cells and serve as a prognostic parameter for non-small cell lung cancer (NSCLC) patients. In the past several decades, many scholars have been dedicated to clarifying the relationships between positive intraoperative pleural lavage cytology results and postoperative survival as well as tumor recurrence and metastasis. However, the findings remained various due to the inhomogeneity of different research. It has been confirmed that a positive intraoperative pleural lavage cytology result is one of the risk factors for the prognosis of postoperative patients. This study reviewed the advances in research of intraoperative pleural lavage cytology in recent years from several aspects, including clinical significance, influencing factors and possible mechanisms. .
【中文题目：肺癌根治术中胸膜腔冲洗液肿瘤细胞检查的研究进展】 【中文摘要：非小细胞肺癌（non-small cell lung cancer, NSCLC）根治术中胸腔冲洗液细胞学检查是一种常用的检测肿瘤进展并评估患者预后的诊断技术。长期以来大量研究者致力于阐明术中胸腔冲洗液细胞学检查结果与肺癌患者术后生存及肿瘤复发转移的关系。由于不同研究间存在明显异质性，其结论也各有不同。但能肯定的是，胸腔冲洗液肿瘤细胞检查阳性已被证实为手术患者的不良预后因素之一。本文尝试从临床意义、影响因素及可能发生机制等角度就近年来术中胸膜腔冲洗的研究进展作一综述。 】 【中文关键词：肺肿瘤；术中胸腔冲洗液；肿瘤细胞；预后 】.
