本文对４６例乳腺癌的术前超声与体检在判断区域淋巴结转移中的可靠性进行分析。全部病例经手术和病理检查。本组超声对腋淋巴结转移的敏感度为７２．４％，特异性为８２．４％，确诊率为７６．１％。而体检的敏感度为４８．３％，特异性为７６．５％，确诊率为５８．７％（Ｐ＜０．０５），两者差异有显著性。在３例扩大根治术中，超声对胸骨旁乳内淋已结的确诊率为３／３。结果提示超声检查对判断乳腺癌的区域淋巴结转移优于体检，具有指导临床的意义。
This article analyzes the reliability of preoperative ultrasound and physical examination of 46 cases of breast cancer in determining regional lymph node metastasis. All cases were examined by surgery and pathology. The sensitivity of this group of ultrasound to axillary lymph node metastasis was 72.4%, the specificity was 82.4%, and the final diagnosis rate was 76.1%. The sensitivity of physical examination was 48.3%, the specificity was 76.5%, and the diagnosis rate was 58.7% (P<0.05). The difference was significant. In 3 cases of extended radical mastectomy, the diagnostic accuracy of ultrasound in paranasal breast milk was 3/3. The results suggest that ultrasound examination is superior to physical examination in judging the regional lymph node metastasis of breast cancer and has clinical significance.
