目的:探讨1992～2006年沈阳市女性乳腺癌死亡率水平及变化趋势、特点。方法:用SAS6.12软件对乳腺癌死亡率、死亡构成等指标进行分析,并进行χ2趋势检验。结果:沈阳市女性乳腺癌死亡率呈上升趋势,15年间上升了57.37%,年均增长速度为3.29%。乳腺癌年均死亡率为9.11/10万,标化死亡率为6.69/10万。乳腺癌在恶性肿瘤中的顺位从2006年开始,由原来的第5位上升至第3位。乳腺癌死亡率从35～岁组开始随年龄增加而明显上升,年龄越大,死亡率越高。45～64岁年龄段乳腺癌死亡率随时间推移,呈明显上升趋势,经χ2趋势检验,有高度统计学意义(χ2=22.43,P<0.0001)。结论:沈阳市乳腺癌死亡率上升速度较快,应重点加强45～64岁年龄段女性乳腺癌的防治。
Objective: To investigate the level of breast cancer mortality and its changing trend and characteristics in Shenyang from 1992 to 2006. Methods: SAS6.12 software was used to analyze the mortality and mortality of breast cancer, and to test the trend of χ2. Results: The mortality rate of breast cancer in Shenyang increased by 57.37% in 15 years with an average annual growth rate of 3.29%. The average annual breast cancer death rate was 9.11 / 100,000, the standardized mortality rate was 6.69 / 100,000. The ranking of breast cancer in malignant tumors from 2006 onwards, rose from the first 5 to 3. The mortality rate of breast cancer increased significantly with the increase of age from 35 to the age group. The higher the age, the higher the mortality rate. The mortality rate of breast cancer in 45-64 age group increased obviously with the passage of time. There was a high statistical significance (χ2 = 22.43, P <0.0001) by χ2 trend test. Conclusion: The incidence of breast cancer in Shenyang is rising rapidly, and the prevention and treatment of breast cancer in 45-64 age groups should be emphasized.
