天津市男性恶性肿瘤患者的发病特征与吸烟情况分析

Smoking Status of Male Cancer Patients in Tianjin

[目的]分析天津男性肿瘤患者发病与吸烟的关系,用循证数据诠释吸烟的危害。[方法]应用覆盖全市户籍人口的天津肿瘤登记系统收集患者的吸烟信息,并结合患者的诊断等信息综合分析男性肿瘤患者中发病与吸烟的关系。[结果]2010~2013年天津男性前5位的恶性肿瘤分别是肺癌、肝癌、结直肠癌、胃癌和膀胱癌,患者中吸烟的构成比明显高于非吸烟者,吸烟者的发病率均显著高于非吸烟者,其中肺癌吸烟者的发病风险是非吸烟者3.26倍（OR=3.26;95%CI：3.14~3.38）。前5位恶性肿瘤的发病病例中,吸烟者的发病年龄早于非吸烟者1.35年（P〈0.01）。城市吸烟男性的恶性肿瘤发病率高于农村吸烟男性,而发病年龄则是农村早于城市,二者差异均有统计学意义（P〈0.01）。[结论]吸烟与多脏器、多系统的恶性肿瘤高发有关,控制吸烟应成为疾病预防控制的重要任务。

[Purpose] To investigate smoking status among male cancer patients in Tianjin.[Methods] Smoking status of cancer cases were collected with the Tianjin Cancer Registry System,which covers the entire population in Tianjin.And the relationship between cancer incidence and smok-ing was analyzed.[Results] From 2010 to 2013,the top 5 cancers among males in Tianjin were lung,liver,gastric,colorectal and bladder cancer.Among cancer cases,the proportion and incidence rate of smokers were significantly higher than those of non-smokers.The relative risk of lung cancer in male smokers was higher than that in non-smokers（OR=3.26;95%CI：3.14~3.38）.In the top 5 cancers,the age of onset among smokers was 1.35 years earlier than that among non-smokers（P〈0.01）.In addition,the incidence of cancer in urban male smokers was higher than that in rural,while the age of onset was later than that in rural,and the differences were statistically significant（P 〈0.01）.[Conclusion] Smoking is related to the high cancer incidence of multiple organs and systems.Therefore,tobacco control should be an important task for cancer prevention and control.
