浙江省肿瘤登记地区结直肠癌流行趋势

目的]分析浙江省肿瘤登记地区结直肠癌的发病、死亡及变化趋势。方法]对浙江省6个肿瘤登记地区2000~2009年结直肠癌发病、死亡资料进行分析,分别计算发病率、死亡率、中国人口标化率（中标率）、世界人口标化率（世标率）,2000~2009年发病率和死亡率变化趋势采用年度变化百分比（APC）估计。结果]2000~2009年结直肠癌发病率为30.24/10万（男性33.28/10万,女性27.11/10万）,中标率15.54/10万,世标率20.42/10万,构成比11.14%,居全部恶性肿瘤发病的第3位。发病高峰出现在80~岁年龄组,达170.86/10万。结直肠癌死亡率为12.31/10万（男性13.53/10万,女性11.05/10万）,中标率5.57/10万,世标率7.70/10万,构成比7.76%,居全部恶性肿瘤死亡的第4位。男、女性死亡的高峰年龄分别为为85岁以上组和80~岁组。2000~2009年,结直肠癌发病率、死亡率均呈上升趋势,APC分别为3.76%、4.40%。结论]浙江省结直肠癌的发病率和死亡率均呈上升趋势,提示应该进一步加强结直肠癌的防治工作,高龄人群应作为结直肠癌防治的重点对象。

An Analysis on Epidemiological Trend of Colorectal Cancer in Cancer Registries in Zhejiang Province

Purpose] To analyze the incidence and mortality of colorectal cancer in the cancer registration areas of Zhejiang province. Methodsl Data from 6 cancer registration areas of Zhe- jiang province from 2000 to 2009 were collected. Crude incidence （mortality）,age-specific inci- dence （mortality） , age -standardized incidence rate by Chinese standard population （ASR China） and by world standard population （ASR world） were calculated. Trend of incidence and mortality of colorectal cancer between 2000 and 2009 was estimated by annual percentage change （APC）. ~Results] From 2000 to 2009,the crude incidence of colorectal cancer in registration areas in Zhejiang was 30.24/105 （males 33.28/105, females 27.11/10~）, ASR China and ASR world were 15.54/ 105 and 20.42/105 respectively. Colorectal cancer accounted for 11.14% ,and ranked the 3th. The peak age incidence was 80~years age group （170.86/105）. The crude mortality was 12.31/105（males 13.53/105,females 11.05/105） ,ASR China and ASR world were 5.57/105 and 7.70/105 respectively, Coloreetal cancer accounted for 7.76%,and ranked the 4th. The peak age incidence was 80-years age group （170.86/105）. The peak ages mortality for male and female were above 85 years and 80- years age group ,respectively. The incidence and mortality of colorectal cancer increased from 2000 to 2009,APC was 3.76% and 4.40%,respectively. Conclusions] The incidence and mortal- ity of colorectal cancer increased in Zhejiang. Prevention and control strategies for colorectal can- cer should be strengthened. Elderly people are important target of prevention and treatment.
