本文报道28例胸部肿物超声引导针吸细胞学检查结果、恶性肿瘤19例、细胞学检查15例发现癌细胞、阳性率79%;良性肿物9例,细胞学检查无一例假阳性,诊断总正确率86%。其中肺癌阳性率为80%。作者认为;对于支气管镜检难以达到而超声能够显示的肺、胸膜、纵膈肿瘤进行超声引导的针吸细胞学检查,简便、安全、准确、可为胸部肿瘤的病理诊断提供一种新的有效方法。 This article reported 28 cases of chest tumor ultrasound-guided needle cytology test results, 19 cases of malignant tumors, cytology 15 cases found cancer cells, the positive rate of 79%; benign tumors in 9 cases, no one case of false positive cytology, diagnosis The total accuracy is 86%. The positive rate of lung cancer was 80%. The authors believe that ultrasound-guided needle-aspiration cytology for lung, pleural, and mediastinal tumors that are difficult to achieve with ultrasound bronchoscopy can be easily, safely, accurately, and provide a new and effective pathological diagnosis of thoracic tumors. method.
