作者报道了在美国国家煤工尸解的研究,对171例煤工肺癌的组织类型进行分析。本组煤工的采煤工龄平均29±14年.平均吸烟史31±23色/年,从诊断原发性肺癌到死亡平均存活时间为11个月。肺癌的细胞类型,鳞状细胞癌占30%,腺癌27%,小细胞未分化癌26%,大细胞未分化癌9%,混合型癌8%,混合型癌中最常见的是腺鳞癌.右肺和两肺上叶分别比左肺和两肺下叶发生肿瘤为多,两肺上叶的肿瘤约等于两肺下叶和主支气管肿瘤的总和;大部分(81%)肺癌集中在软骨的气管中,周围肺组织的肺癌只占19%.鳞状细胞癌在高龄组煤工中(平均年龄为68±9
The authors report the study of autopsy in coal miners in the United States and analyzed the tissue types of lung cancer in 171 coal miners. The average age of coal mining workers in this group was 29±14 years. The average smoking history was 31±23 colors/year, and the average survival time from diagnosis of primary lung cancer to death was 11 months. The cell types of lung cancer are squamous cell carcinoma 30%, adenocarcinoma 27%, small cell undifferentiated carcinoma 26%, large cell undifferentiated carcinoma 9%, mixed type carcinoma 8%, and the most common type of mixed type carcinoma is glandular scales. Cancer. There were more tumors in the right lung and upper lung than in the left lung and lower lung. The tumors in the upper lobes of the two lungs were equal to the sum of the lungs in the lower lobe and the main bronchi; the majority (81%) of lung cancers were concentrated. In the trachea of the cartilage, lung cancer in the surrounding lung tissue accounts for only 19%. Squamous cell carcinoma in the elderly group of coal workers (mean age of 68 ± 9
