Diagnostic value of MRI in axillary lymph node metastasis of early breast cancer / 国际外科学杂志

ABSTRACT

Objective To explore the diagnostic value of MRI special use of breast and uhrasonography in axillary lymph node metastasis of early breast cancer.Methods Clinical data of 136 Ⅰ-Ⅲ A breast cancer patients accepted MRI examination before surgery had been retrospectively studied,analysing diagnostic value of MRI and ultrasonography in axillary lymph node metastasis of early breast cancer.Results The sensitivity,specificity,and accuracy obtained by MRI were 83.3％,88.6％ and 86.3％.And these data of ultrasonography were 73.1％,76.7％ and 75.0％.The sensitivity,specificity,and accuracy obtained MRI were better than that of ultrasonography.The sensitivity,specificity,and accuracy of ≥ 50 years old patients were 70.0％,77.8％ and 75.0％.And ＜ 50 years old patients were 85.7％,92.3％ and 88.9％.The sensitivity,specificity,and accuracy of ＜ 50 years old patients were better than ≥ 50 years old patients.Conclusions The MRI special use of breast have an important value in axillary lymph node metastasis of early breast cancer,especially to gounger than 50 years old patients.It can provide a scientific basis of the clinical accurate treatment for early breast cancer patients.
