[Tobacco smoking and lung cancer: relative risk for Kreyberg groups I and II (author's transl)].
This paper provides additional information about the not yet completely solved relation of smoking and lung cancer of group Kreyberg II. This problem was analysed for the first time in Austria. In retrospective case-control-study datas were collected about smoking habits of 494 male patients with verivied lung cancer (440 cases belonging to group Kreyberg I and 54 to group Kreyberg II) and 1000 controls. By a computer program the relative risk of smokers compared to non smokers, additionaly in relation to the amount of cigarettes smoked, was calculated for: all lung cancer types, groups Kreyberg I and Kreyberg II. The relative risk for smokers compared to non smokers was for Kreyberg I-tumours 7.78 and for Kreyberg II-tumours 3.42 (statistically significant). In relation to the amount of cigarettes smoked, Kreyberg I-tumours had a significant risk at an amount up to 5000 consumed cigarette packs, Kreyberg II-tumours at an amount of more than 20000 cigarette packs.
