不少国家肺癌的死亡率已升至恶性肿瘤的第一位。我国上海1960年肺癌死亡率在恶性肿瘤中占第六位,1963年升至第三位,1975年升至第二位;1975年北京市恶性肿瘤死亡中,肺癌占首位。目前,肺癌虽经综合治疗,其五年生存率仍不到10%,若能早期发现和手术,五年生存率可提高到50%以上。本文对我院用纤维支气管镜(以下简称纤支镜) In many countries, the mortality rate of lung cancer has risen to the top of malignant tumors. China’s Shanghai lung cancer mortality rate ranked sixth among malignant tumors in 1960, rose to third place in 1963, and rose to second place in 1975; lung cancer accounted for the first place in the death of malignant tumors in Beijing in 1975. At present, despite the comprehensive treatment of lung cancer, its five-year survival rate is still less than 10%. If early detection and surgery are performed, the five-year survival rate can be increased to more than 50%.
