分析1981年～1985年死于肺癌的尸体解剖资料2000例,生前临床误诊408例(20.4％)。①误诊为其他器官肿瘤或原发瘤部位不明185例(45.3％),大多数是把肺癌转移灶误诊为原发肿瘤。误诊为消化器官(食管、胃、肝)肿瘤71例,误诊为脑瘤和脊髓瘤30例,肾和尿路肿瘤14例,其他器官肿瘤29例,原发瘤部位不明41例。②因患有心血管病而漏诊肺癌91例(22.3％)。其中冠心病51例(包括急性心肌梗塞19例),高血压病31例(包括脑血循环障碍和卒中12例),动脉硬化9例。⑧误诊为其他肺病77例(18.9％),其中慢性非特异性肺病30例,局灶性肺炎28例,肺结核14例,其他肺病5例。④其余55例误诊为多种疾病。 年龄与误诊的关系:20～29岁肺癌194例,误诊41
Analyzed 2,000 cases of cadaveric anatomy that died of lung cancer from 1981 to 1985. There were 408 misdiagnosed cases (20.4%). 1 Misdiagnosed as 185 cases (45.3%) of unknown tumors or primary tumors in other organs, most of them misdiagnosed lung cancer metastases as primary tumors. Misdiagnosed as 71 cases of digestive organs (esophageal, gastric, liver) tumors, misdiagnosed as brain tumors and spinal cord tumors in 30 cases, renal and urinary tract tumors in 14 cases, 29 cases of other organ tumors, the primary tumor site is unknown 41 cases. 2 91 cases (22.3%) had missed diagnosis of lung cancer due to cardiovascular disease. There were 51 cases of coronary heart disease (including 19 cases of acute myocardial infarction), 31 cases of hypertension (including cerebral blood circulation disorder and stroke in 12 cases), and 9 cases of arteriosclerosis. 8 Misdiagnosed as other pulmonary diseases in 77 cases (18.9%), including 30 cases of chronic non-specific lung diseases, 28 cases of focal pneumonia, 14 cases of pulmonary tuberculosis, and 5 cases of other pulmonary diseases. 4 The remaining 55 cases were misdiagnosed as multiple diseases. The relationship between age and misdiagnosis: 20 to 29-year-old lung cancer in 194 cases, misdiagnosis 41
