Abstract
Additional information about the not yet completely solved relation of smoking and lung cancer of group Kreyberg II was provided. This problem was analyzed for the 1st time in Austria. In a retrospective case-control study, data were collected about smoking habits of 494 male patients with verified lung cancer (440 cases belonging to group Kreyberg I and 54 to group Kreyberg II) and 1000 controls. Using a computer program the relative risk of smokers compared to non-smokers and the 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 7.78 for Kreyberg I tumors and 3.42 for Kreyberg II tumors (statistically significant). In relation to the amount of cigarettes smoked, Kreyberg I tumors had a significant risk at an amount up to 5000 consumed cigarette packs, Kreyberg II tumors at an amount of more than 20,000 cigarette packs.
