【摘要】 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。更多还原

【Abstract】 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 11167 cases were from urban areas and 2 368 cases were from rural areas,underwent breast cancer screening that included clinical 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‰(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 mammography,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.更多还原
