2009-2012年重庆市恶性肿瘤发病趋势分析

Trend analysis of cancer incidence from 2009 to 2012 in Chongqing

目的了解重庆市恶性肿瘤发病趋势变化,为开展肿瘤防治工作提供依据。方法分析重庆市4个城市与5个农村肿瘤登记点2009-2012年肿瘤报告数据,统计分析肿瘤发病率与构成比,采用Logistic曲线估计的方法判别肿瘤发病率趋势变化。结果重庆市恶性肿瘤报告发病率由2009年的203.29/10万上升至244.58/10万,40-岁（F=125.95,P=0.008）与45-岁（F=225.89,P=0.004）年龄组报告肿瘤发病率呈逐年上升趋势。农村地区肿瘤发病率呈上升趋势（F=18.54,P=0.049）。居前6位的肿瘤分别是肺癌、肝癌、胃癌、乳腺癌、食道癌、结直肠肛门癌,肺癌历年均居第1位,城市点结直肠肛门癌居第2位,农村点食道癌居第2位。结论重庆市恶性肿瘤发病率高,农村地区肿瘤发病率呈上升趋势,恶性肿瘤发病率呈年轻化趋势。

Objective To understand the incidence and the trend of cancer in Chongqing, and provide the evidence for conducting cancer prevention and control. Methods The data of cancer from four urban registration sites and five rural registration sites from 2009 to 2012 were analyzed. The incidence and proportion of cancer was calculated. The trend analysis of cancer was identified by curve estimation of logistic regression. Results Cancer incidence increased from 203.29 / 100 000 in 2009 to 244.58 / 100 000 in 2012 in Chongqing. The trend of cancer incidence increased significantly year by year in 40 years age group（F=125.95,P=0.008） and 45 years age group（F=225.89,P=0.004）. The incidence of cancer in rural area increased significantly（F=18.54,P=0.049）. The top six cancers were lung cancer, gastric cancer, breast cancer, esophageal cancer, and colorectal cancer. The number one cancer was lung cancer from 2009 to 2012. Colorectal cancer was the second in urban registration sites and esophageal cancer was the second in rural registration sites. Conclusion Cancer incidence was high in Chongqing. Cancer incidence in rural area increased significantly year by year. Cancer incidence in Chongqing has a tendency of occurring in younger people. Government should pay more attention to take measures to prevent and control cancer.
