本文报导306例原发肺癌经纤维支气管镜刷检的细胞学检查,均通过病理诊断或临床随访而证实。刷检获阳性诊断者271例(88.6％),其中鳞状细胞癌95例(35.06％),腺癌69例(25.46％),未分化癌49例(18.08％),未定型58例(21.40％)。本文细胞学涂片阳性率为88.6％,高于文献所报导的活检阳性率76.24％～83.6％。讨论并比较刷检和活检的优缺点,以及刷检阳性率较高的原因,如果二者同时运用,可使阳性率进一步提高。
This article reports 306 cases of primary lung cancer by fiberoptic bronchoscopy brush cytology, all confirmed by pathological diagnosis or clinical follow-up. Among the 271 cases (88.6%) with positive diagnosis of brush, 95 (35.06%) were squamous cell carcinomas, 69 (25.46%) were adenocarcinomas, 49 (18.08%) were undifferentiated carcinomas, and 58 (21.40%) were unaltered. ). The cytology smear positive rate was 88.6%, which was higher than the reported biopsy positive rate of 76.24% to 83.6%. Discuss and compare the advantages and disadvantages of brush inspection and biopsy, as well as the reasons for the higher positive rate of brush tests. If both are used simultaneously, the positive rate can be further improved.
