近年来支气管肺癌(简称肺癌)早期诊断技术又推进一步,尤其是纤支镜技术开展,对中心型肺癌管内型观察率可达100％;对五级支气管和六级支气管亦分别达到86％和56％;对周围型肺癌在X线电视下活检率亦有所提高,近年来用激光纤支镜利用血卟啉衍生物(HpD)定位和治疗,利用局部造影剂造影以及电子计算机体层X线扫描(CT),肺灌注扫描(LPS,Lung Perfusion Scanning),肺与胸膜活检等现代技术,使早期肺癌诊断水平有了很大提高,目前原发性支气管肺癌确诊率达60～90％。肺癌已成为工业发达的城市和国家威胁人类生命最严重的疾病之一,其死亡率已上升到癌肿死因的首位,广州地区肺癌死亡率由1972年12.5/10万上升为36/10万。社会上
In recent years, early diagnosis techniques for bronchiolar lung cancer (referred to as lung cancer) have been further advanced. In particular, the development of bronchoscopic techniques has enabled the observation rate of intraductal type of central lung cancer to be up to 100%, and the bronchial and bronchial bronchial tubes have reached 86% respectively. 56%; The biopsy rate for peripheral lung cancer was also increased under X-ray television. In recent years, localization and treatment of hematoporphyrin derivatives (HpD) using laser fiber bronchoscopy, local contrast agent imaging, and computed tomography X were used. Line scan (CT), pulmonary perfusion scan (LPS, Lung Perfusion Scanning), lung and pleural biopsy and other modern technologies have greatly improved the diagnostic level of early-stage lung cancer. The current diagnosis rate of primary bronchogenic lung cancer is 60 to 90%. Lung cancer has become one of the most serious diseases in industrially developed cities and countries that threaten human life. The mortality rate has risen to the top of the cause of cancer deaths. The mortality rate of lung cancer in Guangzhou increased from 12.5 to 100,000 in 1972 to 36/100,000. in society
