本文报告经纤维支气管镜确诊的原发性支气管肺癌78例,临床表现为间断或持续多量内带血或刺激性干咳。作者建议对于年龄在四十岁以上,持续痰内带血二周以上者无论X线有无异常表现皆应高度怀疑肺癌,此时纤维支气管镜检查将有助于早期诊断。 This article reports 78 cases of primary bronchial lung cancer diagnosed by fiberoptic bronchoscopy. The clinical manifestations are intermittent or continuous internal bleeding or irritating dry cough. The authors suggest that lung cancer should be highly suspected in those over the age of 40 who have been continuously exposed to blood for more than two weeks, regardless of abnormal X-ray findings. Fiberoptic bronchoscopy will facilitate early diagnosis.
