乳腺癌筛查中高频B超检查的价值

High frequency B-mode ultrasonography in breast cancer screening

目的:探讨乳腺癌筛查中应用高频B超的价值。方法:对桂林市13 535例(包括1 1167例城区妇女和2 368例农村妇女)35～69岁妇女进行以临床乳腺检查→选择性高频B超→选择性乳腺钼靶(MG)为模式的乳腺癌筛查。结果:最终以病理诊断为标准,共检出乳腺癌(恶性肿瘤)8例,检出率为0.591‰(8/13 535)。其中,高频B超阳性8例,敏感性为100%;MG阳性7例,假阴性1例,敏感性为87.5%。结论:高频B超在乳腺癌筛查中呈现出较高的敏感性,且具有无创,价格低廉,适应范围广,操作方便等优势。

Objective： To investigate the application value of high frequency B-mode ultrasonography in breast cancer screening. Methods： A total of 13 535 women aged 35-69 years in Guilin, of whom 11 167 cases were from urban areas and 2 368 cases were from rural areas, underwent breast cancer screening that included dinical breast examination, high frequency B-mode ultrasonography and selective molybdenum target mammography. Results： Eight cases of breast cancer （malignant breast tumor） were detected in the entire group by final pathological identification, and the detection rate was 0.591%o （8/13 535）. Of the 8 women with breast cancer, all were positive by high frequency ultrasonography, and the sensitivity was 100%; while in molybdenum target mammograph）5 7 cases were positive and one case was false negative, and the sensitivity was 87.5%. Conclusion： High frequency B-mode ultrasonography has high sensitivity in breast cancer screening. It has the advantages of non-invasiveness, low cost, wide range of applicability and easy manipulation.
