我们从未来着眼,由一固定区域居民中收集确诊为肺癌达4年以上的全部病例,并全部随访5年或至死亡,主要目的在于查明在这样一组未加选择的病例中的肺癌预后及其有关因素。并将探讨原发癌在肺中的部位及其同组织学分型和对病人预后可能具有的重要影响。本文为前瞻性研究并尽量不遗漏一例合格的病例。4年里在30万人口中,共有446例病人确诊为肺癌,男420例,女26例。376例经组织学确诊(84%),55例经细胞学确诊(12%),仅有15例(8%)是按临床或X线检查所见确诊。全部用硬式支气管镜检查的只有393例(88%)。首次支气管镜检即可把病人分为两组:①支气管镜可见的为中心癌,②支气管镜检不可见的为周围癌。癌在各肺叶上的位置是根据支气管镜检所见确定,如未做支气管镜检或为周围癌,则根据胸片或X线断层
In the future, we will focus on the collection of all patients diagnosed with lung cancer for more than 4 years from a fixed-area population and follow-up for 5 years or until death. The main purpose is to identify the prognosis of lung cancer in this group of unselected cases. And related factors. It will also explore the location of primary cancer in the lung and its associated histological type and its possible impact on patient prognosis. This article is a prospective study and does not miss a qualified case. A total of 446 patients were diagnosed with lung cancer in 4 years in a population of 300,000. There were 420 males and 26 females. 376 cases were confirmed by histology (84%), 55 cases were confirmed by cytology (12%), and only 15 cases (8%) were diagnosed by clinical or X-ray findings. Only 393 cases (88%) were examined by hard bronchoscopy. For the first time, the patient can be divided into two groups by bronchoscopy: 1 The central cancer can be seen by the bronchoscope, 2 The peripheral cancer can not be seen by the bronchoscopy. The position of the cancer on each lobe is determined by bronchoscopy. If no bronchoscopy or peripheral cancer is found, then the chest X-ray or X-ray fault
