内乳淋巴结是乳腺癌的转移途径之一,早期治疗多应用扩大根治术,但是实践证明,扩大根治切除并不能提高生存率,所以目前已废弃。但近来又有不少文章报道术后包括内乳淋巴结区的放射治疗对生存率有益。 一、可手术乳腺癌内乳淋巴结转移的发生率 据早期扩大根治术后大宗病例分析,内乳淋巴结转移与腋下淋巴结状态关系密切,腋下淋巴结阴 Internal mammary lymph node is one of the metastatic routes of breast cancer. Early treatment is widely used to expand radical mastectomy. However, practice has shown that extended radical resection does not improve survival, so it has been abandoned. However, many recent articles have reported that postoperative radiotherapy including the lymph node area of ​​the internal breast is beneficial for survival. First, the incidence of intraoperative breast lymph node metastasis in operable breast cancer According to the analysis of large cases of early postoperative radical mastectomy, internal breast lymph node metastasis is closely related to the status of axillary lymph nodes, and axillary lymph nodes
