文题释义:
胸膜腔:是位于肺和胸壁之间的一个潜在腔隙。在正常情况下脏层胸膜和壁层胸膜表现上有一层很薄的液体,在呼吸运动时起润滑作用。胸膜腔和其中的液体并非处于静止状态,在每一次呼吸周期中胸膜腔的形状和压力均有很大变化,使胸膜腔内液体持续滤出和吸收并处于动态平衡。
胸腔积液:各种因素使胸膜腔内液体形成过快或吸收过缓,即产生胸腔积液,简称胸水。
摘要
背景:
目前细胞学涂片是胸腔积液的常规检测方法,但其结果往往不能令人满意,实验利用胸腔积液制成细胞块并且结合免疫化学和基因检测的方法完善其结果准确性以及对预后治疗的帮助。
目的:探讨胸水细胞块技术在胸腔积液病理诊断和分析中的应用价值。
方法:收集2016年1月至2017年8月北京大学第一医院病理科胸腔积液标本105例,离心后提取有效成分制作石蜡块切片并苏木精-伊红染色,同时进行免疫组织化学标记,对诊断为肺癌者进一步切蜡膜卷提取脱氧核糖核酸行相关基因检测。
结果与结论:常规细胞学涂片恶性检出率30.5%(32/105),明显低于细胞块切片恶性检出率44.8%(47/105),细胞块切片结合免疫组织化学染色分析恶性检出率最高达57.1%(60/105),并可诊断肿瘤具体组织类型。105例中19例肺腺癌细胞块标本行肺癌相关基因检测,核酸质量均合格,其中13例检测到基因突变。结果说明,细胞块合并免疫组织化学染色是胸腔积液诊断良恶性肿瘤及肿瘤来源有效的方法,并且能够进一步检测基因突变情况。

Abstract:

BACKGROUND: Cytologic smear is a routine detection method for pleural effusion, but the results are far from satisfactory. Therefore, pleural effusion is made into cell block for immunochemistry and gene detection, to improve the detection accuracy, which contributes to the treatment and prognosis of pleural effusion.
OBJECTIVE: To explore the application value of cell block technology in the pathological diagnosis and molecular detection of pleural effusion.
METHODS: Totally 105 cases of pleural effusion samples were collected at Department of Pathology, Peking University First Hospital between January 2016 and August 2017. Effective components extracted after centrifugation were used to make paraffin blocks for hematoxylin-eosin staining and immunocytochemical staining thereafter. Genetic mutations were further detected in the cases of lung cancer diagnosed by cytology. 
RESULTS AND CONCLUSION: The positive rate of routine cytological smear was 30.5% (32/105), which was significantly lower than that of the cell block section (44.8%, 47/105). The positive rate of immunocytochemical staining combined with cell block was the highest one with 57.1%, 60/105). Besides, this method could be used to identify tumor types. Gene mutation detection was performed in 19 cases of lung cancer, among which 13 cases were positive. These results indicate that cell block technology combined with immunocytochemical staining is an effective method for the diagnosis of malignancy and tumor origin in pleural effusion, and can be further used for mutation detection.
