隐性肺癌是指痰或支气管分泌物中找到癌细胞,胸部X线检查阴性,临床无法确定肺癌原发部位,并除外其它器官肿瘤。近年来随着痰脱落细胞的检查,隐性肺癌的发现日见增多,本文报告2例,并讨论有关早期诊断和定位问题。 例1,男性,70岁,1989年3月出现咳嗽、血痰。吸烟30余年,每月约20支。体检未见异常,两次胸部X线检查肺野未见病变。痰细胞学4次查到鳞癌细胞,肺CT未见异常。纤支镜见右肺下叶外基底段似有阻
Recessive lung cancer refers to the finding of cancer cells in the sputum or bronchial secretions. The chest X-ray examination is negative. The primary site of lung cancer cannot be determined clinically, and tumors of other organs are excluded. In recent years, with the examination of sputum exfoliated cells, the discovery of latent lung cancer is increasing day by day. This article reports 2 cases and discusses issues related to early diagnosis and positioning. Example 1, male, 70 years old, had cough and blood stasis in March 1989. Smoking for more than 30 years, about 20 per month. Physical examination did not show any abnormalities. No chest radiographs were found in the two chest radiographs. Squamous cell carcinoma was found on squamous cell carcinoma 4 times, and no abnormalities were found on lung CT. Bronchoscopy see the right lung lower basal segment like resistance
