目的预测N0、N1浸润性非特殊型乳腺癌的Ⅲ级淋巴结转移。方法回顾性分析122例N0、N1浸润性非特殊型乳腺癌全腋窝淋巴结清除病人的腋淋巴结转移状态,应用判别分析,建立预测腋Ⅲ级淋巴结转移状态的判别方程。结果腋淋巴结转移由低向高位发展者占93.55%,肿瘤大小为腋淋巴结转移高危因素。按判别方程预测Ⅲ级腋淋巴结转移概率的总符合率为83.9%。结论N0、N1浸润性非特殊型乳腺癌通过低位腋淋巴结及肿瘤大小信息可预测Ⅲ级淋巴结的转移状态。
Objective To predict grade III lymph node metastasis in N0 and N1 invasive nonspecific breast cancer. Methods The status of axillary lymph node metastasis was analyzed retrospectively in 122 cases of N0, N1 infiltrating non-specific breast cancer patients with axillary lymph node metastases. Discriminant analysis was used to establish a discriminant equation for predicting the status of metastasis of III-level lymph nodes. Results The proportion of axillary lymph node metastasis from low to high accounted for 93.55%. The tumor size was a high risk factor for axillary lymph node metastasis. According to the discriminant equation, the total coincidence rate of class III axillary lymph node metastasis prediction was 83.9%. Conclusion The metastasis of grade III lymph nodes can be predicted from low-grade axillary lymph nodes and tumor size information in N0, N1 infiltrating nonspecific breast cancer.
