本研究以肺癌为例探讨了应用肿瘤登记数据评价职业和行业肿瘤危险度的方法。以天津肿瘤登记处1981～1987年期间的登记数据为基础，利用病例一对照方法研究了肿瘤的职业和行业危险度，共分析了天津市区30个职业和27个行业。每一被研究的职业／行业为暴露组，其它是未暴露组。被研究的肿瘤为病例组，其它为对照组。统计分析方法是非条件logistic回归模型。调整因素包括性别、年龄和诊断年份。结果：以肺癌为例，研究结果与既往报告雷同。对天津市职业和行业的肿瘤危险度进行了系统的分析，提出天津市职业和行业的肿瘤危险因素。这种设计的主要优点是①可充分利用已经有的肿瘤登记的数据。②简便易行的、快速的和低成本地评价肿瘤危险因素或者潜在的危险因素。③所有肿瘤登记或任何疾病登记的数据库的因素均可以被评价，例如职业、行业、教育等。④减少分析中的混杂和偏倚。
In this study, lung cancer was taken as an example to discuss the method of using tumor registration data to evaluate the risk of occupational and industrial tumors. Based on the registration data of the Tianjin Cancer Registry from 1981 to 1987, a case-control method was used to study the occupational and occupational risk of the tumor. A total of 30 occupations and 27 industries in Tianjin were analyzed. Each occupation/industry studied was exposed and the others were unexposed. The tumors studied were case groups and the others were controls. The statistical analysis method is an unconditional logistic regression model. Adjustment factors include gender, age, and year of diagnosis. Results: Take lung cancer as an example. The results of the study are similar to those of previous reports. A systematic analysis of the risks of occupational and industrial cancer in Tianjin was conducted, and the risk factors for occupational and occupational cancer in Tianjin were proposed. The main advantage of this design is that 1 can make full use of existing tumor registration data. 2 Evaluate tumor risk factors or potential risk factors easily, quickly and inexpensively. 3 All the factors of the registration of the tumor or any database of disease registration can be evaluated, such as occupation, industry, education, etc. 4 Reduce confusion and bias in the analysis.
