肺癌是我国常见的恶性肿瘤之一 ,多发于中老年。近年来 ,由于肺癌发病率的逐渐上升 ,肺癌的发病年龄也有提前趋势 ,且误诊率较高。我院自 1992年 1月～ 1998年 3月共收治 35岁以下肺癌患者 2 8例 ,其中误诊 2 4例 ,误诊率达 85 7% ,为争取肺癌患者的早发现、早诊断、早治疗 , Lung cancer is one of the most common malignancies in China and it often occurs in middle-aged and older people. In recent years, due to the gradual increase in the incidence of lung cancer, the age of onset of lung cancer also has an early trend, and the rate of misdiagnosis is high. In our hospital from January 1992 to March 1998, a total of 28 lung cancer patients under the age of 35 were admitted, of which 24 were misdiagnosed. The rate of misdiagnosis was 85.7% for the early detection, early diagnosis and early treatment of lung cancer patients.
