乳腺钼靶X线摄影和B超筛查资料分析

Analysis of breast cancer screening by mammography and ultrasonography

目的探讨乳腺钼靶X线摄影和超声检查两种方法对乳腺癌筛查的价值,以寻找适宜的乳腺癌筛查方法。方法对本地35~69岁经初筛后387名可疑乳腺异常的妇女,行乳腺钼靶X线摄影,有异常或不能评估者再用超声检查,超声检查阳性或可疑者行穿刺活检以确定乳腺癌诊断。结果 387例中,腺体成分在5 0%以上者占83.22%,经X线摄影发现有22例阳性,2 2例阳性经B超检查亦为阳性,75例不能评估。75例不能评估者B超检查有3例阳性。行穿刺活检25例,确诊乳腺癌17例,其中2例已达III期以上。钼靶X线发现乳腺癌的敏感性为72.73%,B超为6 8.0%,差异无统计学意义（P〉0.0 5）。结论本地筛查妇女乳腺大部分为腺体致密型。X线摄影在致密型乳腺的乳腺癌筛查中未呈现出比超声检查的优越性。

Objective To discuss the significance of mammography and ultrasonography in breast cancer screening,and search of an appropriate method for breast cancer screening.Methods A group of 387 women aged from 35 to 69 who were suspected to be an abnormal breast were chosen to undergo mammography,the positive diagnosis and uncertain cases then had ultrasonography,and the positive cases by ultrasonography underwent biopsy to confirm the diagnosis of breast cancer.Results Among the 387 cases,83.22% of breasts contained more than 50% glands,22 cases were positive and 75 cases were uncertain by mammography.The results of 22 positive cases were comfirmed by mammography and ultrasonography,and 3 cases among the 75 uncertain cases by mammogrophy were positive by ultrasonography.Biopsy was performed in 25 cases and 17 of them were confirmed to be breast cancer,while 2 cases of breast cancer had reached stage III.The sensitivity of mammography and ultrasonography was respectively 72.73% and 68.0%;there was no statistically significant differences（P0.05） between the 2 methods.Conclusions Most of the checked breasts in our series were dense,and mammography was not superior to ultrasonography in dense breasts.
