从80年10月至85年12月,我们收检了911例次纤支镜活检材料,诊断为肺癌的有267例,检出阳性率为30％。由于取材的限制,267例肺癌皆属中央型;其中鳞癌最为多见占143例,余依次为腺癌、小细胞癌和大细胞癌,有2例因癌组织太少而不能分类。在911例次活检材料中,有26例分别误诊为假阳性和假阴性,总的误诊率为2.85％,而诊断准确率则为97.15％。 分析了影响纤支镜检出阳性率的各种因素,包
From October 1980 to December 2015, we collected 911 cases of bronchoscopic biopsy materials. Among 267 cases diagnosed as lung cancer, the positive rate was 30%. Due to the limitations of the materials, 267 cases of lung cancer are central types; of these, squamous cell carcinomas are the most common, accounting for 143 cases, followed by adenocarcinomas, small cell carcinomas, and large cell carcinomas. Two cases are too small to be classified because of too few cancerous tissues. Among the 911 biopsy materials, 26 cases were misdiagnosed as false positives and false negatives respectively. The total misdiagnosis rate was 2.85%, and the diagnostic accuracy rate was 97.15%. Analyze the various factors that affect the positive rate of fiber bronchoscope detection.
