本文分析了肺癌诊疗的新近动向。日本1979年肺癌患者死亡19923例,比1974年增加26倍。死亡率与吸烟相关,非吸烟者标化死亡率20.7/10万,吸烟越多死亡率越高。既往吸烟后又戒烟者为41.8/10万,15～19岁开始吸烟者为114.0/10万,30～35岁开始吸烟者为41.8/10万。据日本肺癌学会1976～1978年登记结果,各组织类型肺癌所占比例为:鳞癌40.0%、腺癌37.6%、肺泡癌1.3%、大细胞癌7.6%、小细胞癌10.8%、燕麦细胞癌1.6%、类癌1.1%。其五年生存率依次为:鳞癌14.4%、
This article analyzes recent trends in lung cancer diagnosis and treatment. In 1979, 1923 lung cancer patients died in Japan, a 26-fold increase over 1974. Mortality was associated with smoking. Non-smokers had a standardized death rate of 20.7 per 100,000. The more deaths the smoking, the higher the mortality rate. The number of smokers who quit after smoking was 41.8 per 100,000. The number of smokers who started smoking between the ages of 15 and 19 was 114.0 per 100,000. The number of smokers who started smoking between the ages of 30 and 35 was 41.8 per 100,000. According to the registration results of the Japanese Lung Cancer Society from 1976 to 1978, the proportion of lung cancers of various tissue types was: squamous cell carcinoma 40.0%, adenocarcinoma 37.6%, alveolar carcinoma 1.3%, large cell carcinoma 7.6%, small cell carcinoma 10.8%, oat cell carcinoma 1.6%, carcinoid 1.1%. The five-year survival rate was: squamous cell carcinoma 14.4%,
