摘要

细胞学检查是胸腔积液的重要诊断工具,其诊断效果受标本处理和染色技术变化的影响。采用Wright-Giemsa染色对胸腔积液进行细胞形态学分析,以评估其诊断准确性和在鉴别各种病因的渗出性胸腔积液中的临床应用。对2305例不明原因胸腔积液进行常规检查,对1376例确定为渗出性胸腔积液进行细胞分类和形态学分析。479例恶性肿瘤患者中,细胞形态学检查发现295例患者有恶性细胞,临床诊断符合率为98.6%。异常细胞包括恶性和异质核细胞364例,检出率为76.0%。新诊断患者组恶性肿瘤阳性细胞比例明显高于既往诊断组(P

Evaluation of cytomorphological examination in the diagnosis of pleural effusion.

Cytological examination serves as a crucial diagnostic tool for pleural effusion, with its diagnostic efficacy influenced by variations in specimen processing and staining techniques. Cellular morphological analysis of pleural effusions was performed using Wright-Giemsa staining to assess its diagnostic accuracy and clinical utility in differentiating the various etiologies of exudative pleural effusion. A routine examination was conducted on 2305 cases of unexplained pleural effusion, followed by cellular classification and morphological analysis in 1376 cases identified as exudative effusion. Among the 479 patients with malignant tumors, cytomorphological examination identified malignant cells in 295 patients, resulting in a clinical diagnosis coincidence rate of 98.6%. Abnormal cells, including malignant and heterogeneous nuclear cells, were observed in 364 cases, yielding a detection rate of 76.0%. The proportion of positive malignant cells in the newly diagnosed patient group was significantly higher than that in the previously diagnosed group (P < 0.01). Cytological analysis revealed the presence of bacteria, fungi, and phagocytes in 51 out of 1376 cases. The positivity rate for multiple bacterial infections detected through cytology was significantly greater than that identified by culture (P < 0.01). Additionally, various special morphologies and pathogens, which are rare in clinical practice, were detected, including mixed metastasis of small cell lung carcinoma and adenocarcinoma cells, as well as concurrent infections with Talaromyces marneffei and Pneumocystis jirovecii. This method enables the rapid and comprehensive differentiation between malignant tumors, tuberculosis, pneumonia, and rare exudative pleural effusions resulting from specific clinical conditions.

期刊介绍: Clinical and Experimental Medicine (CEM) is a multidisciplinary journal that aims to be a forum of scientific excellence and information exchange in relation to the basic and clinical features of the following fields: hematology, onco-hematology, oncology, virology, immunology, and rheumatology. The journal publishes reviews and editorials, experimental and preclinical studies, translational research, prospectively designed clinical trials, and epidemiological studies. Papers containing new clinical or experimental data that are likely to contribute to changes in clinical practice or the way in which a disease is thought about will be given priority due to their immediate importance. Case reports will be accepted on an exceptional basis only, and their submission is discouraged. The major criteria for publication are clarity, scientific soundness, and advances in knowledge. In compliance with the overwhelmingly prevailing request by the international scientific community, and with respect for eco-compatibility issues, CEM is now published exclusively online.
