摘要
目的探讨乳腺MRI与彩超对腋窝淋巴结转移的诊断价值。方法回顾性分析136例术前临床分期为Ⅰ-ⅢA期并已经行乳腺MRI检查的乳腺癌患者的临床资料，分析MRI、彩超对腋窝淋巴结的诊断及术后病理结果。结果乳腺MRI对腋窝淋巴结转移诊断的敏感性、特异性和准确性分别为83．3％、88．6％和86．3％，彩超诊断的敏感性、特异性和准确性分别为73．1％、76．7％和75．0％。乳腺MRI诊断早期乳腺癌腋窝淋巴结转移状态的敏感性、特异性和准确性均优于乳腺彩超。乳腺MRI在评价年龄≥50岁患者的腋窝淋巴结敏感性、特异性及准确性分别为70．0％、77．8％和75．0％，而〈50岁患者的敏感性、特异性及准确性分别为85．7％、92．3％和88．9％。乳腺MRI诊断年龄〈50岁早期乳腺癌患者腋窝淋巴结转移状态的敏感性、特异性和准确性均优于≥50岁的患者。结论乳腺MRI评估早期乳腺癌腋窝淋巴结转移的状态具有重要价值，特别是对于〈50岁的早期乳腺癌患者，可为制定准确的临床治疗方案提供有科学的依据。
Objective To explore the diagnostic value of MRI special use of breast and uhrasonography in axil- lary lymph node metastasis of early breast cancer. Methods Clinical data of 136 I - m A breast cancer patients accepted MRI examination before surgery had been retrospectively studied, analysing diagnostic value of MRI and uhrasonography 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 uhrasonography were 73.1% , 76.7% and 75.0%. The sensitivity, specificity, and accuracy obtained MRI were better than that of uhrasonography. 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 oid 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.
