胸腔肿瘤细针针吸活检细胞学诊断

本文报告胸腔肿瘤细针针吸活检细胞学诊断102例的结果。其中恶性肿瘤54例,良性肿瘤14例和炎性病变34例,确诊率分别为96.3％(52/54)、100％(14/14)和97％(32/34)。多孔针头采集标本量多,不但能明确炎性病变及肿瘤的良、恶性,且可确定组织学类型。本组包括鳞癌、腺癌、未分化癌、恶性纤维组织细胞瘤、尤文氏肉瘤、间皮肉瘤、恶性淋巴瘤和转移癌。本文恶性肿瘤的确诊率比文献中报道的痰检与气管镜活检的阳性率分别高24.6％与14.65％。提高了胸腔肿瘤诊断率。

Value of Fine Needle with Fenestrations Aspiration Cytology in Diagnosis of Thoracic Mass

Results of 102 thoracic percutaneous aspiration biopsies performed with a fenestrated fine needle were analysed. Patients with thoracic mass (pulmonary, mediastinal or chest wall) with only roentgenographic but no other evidences were selected for this procedure. The accurate rate of this procedure for carcinoma, benign tumor and inflammatory lesion was 96.3%, 100% and 97% respectively. The specimen obtained allow not only for distinguishing benign from malignant, but also good for histologic typing. Microscopic observation of the aspirates was successful in identifying types of tumor as follows: squamous carcinoma, adenocarcinoma, undifferentiated carcinoma, malignant lymphoma, malignant thymoma, malignant fibrous histocytoma, mesothelioma, Ewing's sarcoma and metastatic carcinoma. The authors conclude that this technic is a useful and reliable method for the diagnosis of intrathoracic mass with higher accuracy than sputum cytology and bronchoscopic aspiration cytology.
