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 not 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 life time cigarette consumption: less than 5000 packs of cigarettes smoked 1,94; 5000--20 000 packs smoked 6,44 (statistically significant); more than 20 000 packs 10,92 (statistically significant). The respective figures for Kreyberg II tumors are 1,2; 1,72; 1,73.
在一项回顾性病例对照研究中(360名患有非烟草相关疾病的女性对照患者),分析了180名女性肺癌患者(119例克雷伯格I型肿瘤,61例克雷伯格II型肿瘤)的吸烟习惯和吸烟史。吸烟者患克雷伯格I型肿瘤的相对风险为5.7(具有统计学意义),患克雷伯格II型肿瘤的相对风险为1.57。患克雷伯格I型肿瘤的风险随着终生香烟消费量的增加而上升:吸烟少于5000包为1.94;吸烟5000 - 20000包为6.44(具有统计学意义);吸烟超过20000包为10.92(具有统计学意义)。克雷伯格II型肿瘤的相应数字分别为1.2;1.72;1.73。
