乳癌淋巴结转移的有无和程度与预后有密切关系。淋巴结转移阳性组和阴性组的5年、10年生存率有明显差异。而且转移的程度对生存率影响较大,据美国的ACS调查,对19933例观察腋窝淋巴结转移数目和5年生存率的关系,阴性转移72％,淋巴结1个63％,4个52％,随着转移数增多而生存率逐渐减少,21个以上为22％。腋窝淋巴结转移的程度和原灶大小关
The presence and degree of lymph node metastasis in breast cancer are closely related to prognosis. The 5-year and 10-year survival rates of the positive and negative lymph node metastases were significantly different. Moreover, the degree of metastasis has a great influence on survival rate. According to the US ACS survey, the relationship between the number of axillary lymph node metastases and the 5-year survival rate in 19933 cases was 72% for negative metastases, 63% for lymph nodes, and 45% for 52%. The number of metastases increased and the survival rate gradually decreased, with 21 or more being 22%. The degree of axillary lymph node metastasis and the size of the primary tumor
