182例肺癌病人癌症家族史的分析

本文调查了182例肺癌病人及200例非肿瘤病人及200例非肿瘤病人（对照组）的癌症家庭史，分析结果：①肺癌组家庭患癌率为19.2%，其中直系亲属占94%，对照组家庭患癌率为20%，其中直系亲属占85%，肺癌组直系亲属患癌比例大于对照组，提示：肺癌的发病与遗传因素可能有相关性。②将三种不同组织类型肺癌病人的家庭患癌率作了比较，小细胞肺癌（Sclc）组最高为26.6%，其次是腺癌21%，鳞癌最低为10%，提示Sclc很可能与癌遗传因素有关。

Family history analysis of 182 cases lung cancer.

We investigated the family history of 182 lung cancer patients and 200 non-cancer patients(for comparison).Results:1.Cancer morbidity among family members of the cancer group is 19.2%,in which the morb idity among the directly-related me mbers is 94%,cancer morbidity among family members of the non-cancer group is 20%,in which the morbidity among the directly-related members is 85%. The cancer morbidity among the directly-related members of the cancer group is higher than that of the non-cancer group.Though it shows no significance in statistics,it implicates the correlationship betw een morbidity and genetic factors.2.Comparison of the morbidity of the family members from the three types of lung cancer:family morbidity among small cell anaplastic carcinoma group is 26.6%,the highest family morbidity among adenocarcinoma group is 21%,the middle. Family morbidity among epidermoid carcinoma group is 10%,the lowest.It implicates genetic factors have direct bearing on the incidence of small cell anaplastic carcinoma.
