目的:分析2009～2010年长春市区内乳腺癌筛查结果并探讨导致筛查结果差异性的原因,为优选乳腺癌筛查方案提供参考。方法:对连续两年同一城区人口自愿初始筛查人群16 830例样本进行整理分析。从被筛人群的年龄分布特点、阳性检出率及检出癌的分期情况、癌症人群的年龄分布情况、完成筛查流程的情况、不同检查方法对早期癌检出作用等方面加以分析和总结。结果:①一站式(完成筛查流程在医院)比分站式(完成筛查流程从社区到医院)乳腺癌的检出率高,两者比较差异有统计学意义(P<0.05)。②2009～2010年自愿筛查人群的年龄分布无明显差异,但是和城区实际人口分布情况有差异(35～44岁年龄段多于实际分布、45～49岁年龄段明显多于实际分布、50～54岁无明显差别,接近实际分布、55～59岁和65～69岁年龄段少于实际分布、60～64岁年龄段明显少于实际分布)。③建议进行彩超和X线检查的人群比例无明显差异,但完成筛查流程的人群的比例不同,差异有统计学意义(P<0.05)。④在早期癌的诊断方面乳腺X线优于乳腺彩超。结论:①一站式从乳腺癌的阳性检出率、完成筛查的人群比例和早期癌的检出率方面都优于分站式。②从人群的年龄分布方面,筛查的结果仅为筛查的患病率,不能代表该区域内的乳腺癌发病率;③乳腺癌筛查在现阶段采用对临床确认为高危人群进行乳腺X线检查可能更有意义。
OBJECTIVE: To analyze the results of breast cancer screening in Changchun from 2009 to 2010 and to explore the causes of the differences in screening results, so as to provide a reference for screening breast cancer screening programs. Methods: 16 830 samples of voluntary initial population screening in the same urban area for two consecutive years were analyzed. From the characteristics of age distribution of the sieved population, the positive detection rate and the detection of cancer staging, the age distribution of cancer patients, the completion of the screening process, different detection methods to detect the role of early cancer to be analyzed and summarized . Results: (1) The one-stop (complete screening procedure in hospital) breast cancer detection rate was higher (P <0.05). (2) There was no significant difference in the age distribution of the voluntary screening population between 2009 and 2010, but the distribution was different from the actual population distribution in the urban area (35-44 age group was more than the actual distribution, 45-49 age group was significantly more than the actual distribution, 54-year-old no significant difference, close to the actual distribution, 55 to 59 years old and 65 to 69 age groups less than the actual distribution, 60 to 64 age groups was significantly less than the actual distribution). ③ Proposed color Doppler ultrasound and X-ray examination of the proportion of people no significant difference, but the completion of the screening process of the proportion of different populations, the difference was statistically significant (P <0.05). ④ in the diagnosis of early breast mammography is better than the breast ultrasound. Conclusion: ① The positive rate of one-stop breast cancer, the proportion of people who completed screening and the detection rate of early stage cancer are better than the substation type. ② from the age distribution of the population, the screening results only the prevalence of screening, can not represent the incidence of breast cancer in the region; ③ breast cancer screening at this stage using clinically recognized high-risk population for breast X Line inspection may make more sense.
