Abstract
The smoking habits and history of 180 female lung cancer patients (119 cases of Kreyberg I tumors, 61 cases of Kreyberg II tumors) were analyzed in a retrospective case control study (360 female control patients suffering from non tobacco related diseases). The relative risk for smokers is 5.7 for Kreyberg I tumors (statistically significant) and 1.57 for Kreyberg II tumors. The risk for Kreyberg I tumors rises in relation to the lifetime cigarette consumption: < 5000 packs of cigarettes smoked, 1.94; 5000-20,000 packs smoked, 6.44 (statistically significant); > 20,000 packs, 10.92 (statistically significant). The respective figures for Kreyberg II tumors are 1.2, 1.72 and 1.73.
