前言吸烟作为肺癌病因早已肯定,国外认为它占病因之80-85％。但国内文献报导它对肺癌相对危险性不及国外高,而普遍关注室内煤烟的危害。除此而外,职业毒害、被动吸烟、既往疾病、厨房炊烟、妇女特殊病因、戒烟的有效性等等均未最后阐明。我们组织省内七个不同大小城市,进行病例一对照调查(共703对)。对上述各方面共230余变量进行多因素分析,找到北方城市肺癌发病主要原因有吸烟、室内煤烟污染、三种职业毒害、三种既往疾病。分析了它们在病因中所占比重。肯定了戒烟和改烧煤气在降低发病中的作、用。
Foreword Smoking has long been recognized as the cause of lung cancer, and it is believed by foreign countries that it accounts for 80-85% of the causes. However, domestic literature reports that it is less dangerous than lung cancer in foreign countries, and it is generally concerned about the hazards of indoor soot. In addition, occupational poisoning, passive smoking, past illnesses, smoking in the kitchen, special etiology of women, and the effectiveness of smoking cessation have not been finally clarified. We organized seven different cities in the province for a case-control survey (a total of 703 pairs). A total of 230 variables in the above-mentioned aspects were multivariate analyzed. The main causes of lung cancer in northern cities were smoking, indoor soot pollution, three occupational toxicities, and three previous diseases. Analyze their share in the cause. It affirms the work and use of smoking cessation and gas conversion in reducing the incidence.
