早期乳腺癌的超声和X线摄影的对照研究

Controlled Study of Ultrasonography with Mammography for the Diagnosis of Early Breast Cancer

目的 探讨早期乳腺癌的超声和X线的特征性表现 ,提高其诊断率。材料与方法 5 0例乳腺癌和 2 0例乳腺良性病变均行B超和X线检查 ,乳腺摄片时间为月经后 10天内 ,所有病例均经病理证实。结果 B超诊断早期乳腺癌 3 9例 ,其敏感性和特异性分别为 78.0 %和 85 .0 % ,准确性为 80 .0 % ;X线诊断早期乳腺癌 41例 ,其敏感性和特异性分别为 82 .0 %和 90 .0 % ,准确性为84.3 %。二者综合诊断 ,其敏感性和特异性为 96.0 %和 76.5 % ,准确性为 90 .4%。结论 二者综合检查可提高早期乳腺癌诊断的敏感性和准确性。

Objective To study the ultrasonographic and mammographic characteristics of early breast cancer, and to improve its diagnostic accuracy.Materials and Methods Fifty patients with breast cancer and 20 patients with benign breast masses, proved pathologically, underwent ultrasonography and mammography within 10 days after mensis.Results Ultrasonography demonstrated breast cancer in 39 cases, the sensitivity and specificity were 78.0% and 85.0%, respectively, with the accuracy of 80.0%; while mammography revealed breast cancer in 41 cases, the sensitivity and specificity were 82.0% and 90.0%, respectively, with the accuracy of 84.3%. The sensitivity, specificity and accuracy could reach to 96.0%, 76.5% and 90.4%, respectively, when ultrasonography and mammography were combined together.Conclusion Ultrasonography combined with mammography can increase the diagnostic sensitivity and accuracy of early breast cancers.
