目的了解苏州市大肠癌死亡变化趋势。方法根据2002-2015年苏州市死亡登记资料和人口数据,采用描述性研究方法,计算大肠癌粗死亡率、标化死亡率和死亡率平均增长速度,利用趋势性检验分析大肠癌死亡率变化趋势。结果2002-2015年苏州市因大肠癌死亡共11 137例,粗死亡率为12.71/10万,标化率为9.05/10万;以直肠癌(粗死亡率为7.07/10万,标化率为5.05/10万)最高,结肠癌(粗死亡率为5.46/10万,标化率为3.88/10万)次之,肛门癌最低(粗死亡率为0.18/10万,标化率为0.13/10万)。平均增长速度粗死亡率为4.87%,标化率为2.02%。趋势性检验表明,2002-2015年粗死亡率有一定上升趋势(P=0.00),标化率没有变化趋势(P=0.87),其中直肠癌和结肠癌粗死亡率、标化率均呈上升趋势(P<0.05)。男性大肠癌死亡率均高于女性,40岁之前死亡率一直处于较低水平,此后随着年龄的增长而快速上升,男、女性均在≥85岁年龄组达到最高水平(157.57/10万、94.22/10万)。结论苏州市大肠癌死亡率处于较高水平,结肠癌和直肠癌呈现增长趋势,应积极采取有效干预措施。
Objective To understand the trend of death of colorectal cancer in Suzhou City. Methods According to the death registration data and population data from 2002 to 2015 in Suzhou City, the descriptive research methods were used to calculate the average growth rate of crude, standard and mortality of colorectal cancer, and the trend of colorectal cancer mortality was analyzed by trend test . Results A total of 11 137 cases of death from colorectal cancer in Suzhou City from 2002 to 2015 were found. The crude mortality rate was 12.71 / 100 000 and the standardization rate was 9.05 / 100 000. The rectal cancer (crude mortality rate 7.07 / 100 000, normalization rate (5.05 / 100000), colon cancer (crude death rate 5.46 / 100000, the standardization rate of 3.88 / 100000) followed by the lowest anal cancer (crude mortality of 0.18 / 100000, the standardization rate of 0.13 /100,000). The average growth rate of crude mortality was 4.87%, the standardization rate of 2.02%. The trend test showed that there was a certain upward trend of crude mortality (P = 0.00) and no change of standardization rate (P = 0.87) between 2002 and 2015. Crude death rate and standardization rate of rectal cancer and colon cancer increased Trend (P <0.05). Mortality rate of colorectal cancer in males was higher than that in females, the mortality rate before the age of 40 was at a low level, then increased rapidly with age, male and female reached the highest level of ≥85 years old (157.57 / 100000, 94.22 / 100,000). Conclusion The mortality rate of colorectal cancer in Suzhou City is at a high level. The growth of colon cancer and rectal cancer shows an increasing trend. Effective intervention measures should be actively taken.
