辽宁省沈阳市城市地区2016-2018年度乳腺癌筛查结果分析

目的 分析辽宁省沈阳市城市地区乳腺癌筛查效果。方法 采用整群抽样的方法,收集2016年11月—2019年3月辽宁沈阳地区40~74岁参与乳腺癌筛查女性的筛查数据,符合要求的女性应用防癌风险评估问卷评估,评估出的高危人群进一步进行临床检查。结果 共57664名女性参与乳腺癌高危风险评估,评估出高危人群18885名,5664名女性参与乳腺癌临床检查,阳性(BI-RADS 4-5类)检出率为6.59%,50~59岁年龄段阳性检出率较高,差异有统计学意义(χ²=10.34,P=0.006),不均匀致密型和致密型乳腺中阳性检出率显著高于脂肪型和纤维腺体型(χ²=22.05,P＜0.001)。各年龄段女性乳腺X线技术阳性检出率均高于超声,实质类型中,除外脂肪型,乳腺X线技术阳性检出率均高于超声,差异均有统计学意义(P＜0.05)。结论 50~59岁女性是乳腺癌防控的重点人群,超声在致密型乳腺中阳性病例的检出优势不明显。

Analysis of breast cancer screening results in urban areas of Shenyang,Liaoning province,2016-2018

Objective The aim of this study was to analyze the screening effect of breast cancer in Shenyang,Liaoning province.Methods Cluster sampling method was used to collect the screening data of 40~74 years old women who participated in breast cancer screening in Shenyang area of Liaoning from November 2016 to March 2019.The women who met the requirements were assessed with the cancer prevention risk assessment questionnaire,and the high-risk groups were evaluated for further clinical examination.Results A total of 57664 women participated in the high-risk assessment of breast cancer.Amongst of them,18885 women as the high-risk for breast cancer were assessed,and 5664 women participated in the clinical examination of breast cancer.The positive(BI-RADS 4-5)detection rate was 6.59% in the age group of 50~59 years(χ²=10.34,P=0.006).The positive rate of heterogeneously dense and extremely dense breast type was higher than that of fat type and fibroglandular type(χ²=22.05,P＜0.001).The positive detection rate of mammography in all age groups was higher than that of ultrasound in parenchyma type except for fat type.Conclusion Women aged 50~59 years old are the key population of breast cancer prevention and control,and the detection advantage of ultrasound in the positive cases of dense breast was not obvious.
