T_1,T_2期乳腺癌估计有80％和65％无腋淋巴结转移,无需手术清除。随着早期乳腺癌诊断的增多,术前确定腋淋巴结是否转移对临床手术有十分重要的意义。本文前瞻性对比研究了B超(USG)、触诊(CE)与病理诊断胞淋巴结转移的意义。 作者对200例手术的乳腺癌(Tx,T_1,T_2,T_3和NO或N_1),术前CE触及肿大淋巴 T_1 and T_2 breast cancers are estimated to have 80% and 65% no axillary lymph node metastases and no surgical removal is required. With the increase of the diagnosis of early breast cancer, it is of great significance to determine whether axillary lymph nodes metastasize before surgery. This article prospectively compared the significance of ultrasonography (USG), palpation (CE), and pathological diagnosis of lymph node metastasis. The authors explored 200 cases of surgical breast cancer (Tx, T_1, T_2, T_3, and NO or N_1), and preoperative CE touched lymph nodes.
