目的

探讨乳腺癌腋窝肿块的位置、大小与腋窝淋巴结转移的关系。

方法

应用SPSS13.0统计分析软件，前瞻性分析2000年11月至2007年10月间201例乳腺癌患者腋窝Ⅰ、Ⅱ、Ⅲ组以及胸肌间淋巴结（Rotter）转移情况。

结果

201例乳腺癌患者中，腋窝淋巴结存在转移者104例（51.74%）；随肿瘤体积的增大，腋窝Ⅰ、Ⅱ、Ⅲ组淋巴结的转移率均明显增高；外、中、内三个带区的乳腺癌在各级腋淋巴结的转移率上无显著统计学差异；胸肌间淋巴结发现率和转移率较低。

结论

应重视对乳腺癌患者尤其是肿瘤体积大、分期晚的病人腋窝Ⅲ组淋巴结的清扫；不应随意放弃全腋淋巴结清扫术；不应将肿瘤的生长位置作为判断腋窝淋巴结是否存在转移的依据；在手术过程中应当将胸肌间淋巴结一并清扫。

Objective

To explore the rule of axillary lymph nodes metastasis(ALNM) and discussing the relationship between ALNM with tumor size and location to guide the dissection range of breast cancer operation.

Methods

201 patients with breast cancer entered the research during Nov.2000～Oct.2007.Collected the datum(size and location of the tumor) of the patients and group the axillary lymph nodes into levelⅠ,Ⅱ,Ⅲand interpectoral lymph nodes（Rotter）before the pathologic examination. Use the SPSS 13.0 software for statistical analysis.

Results

104 cases in the research of 201 patients with breast cancer had the ALNM.The metastasis ratio was 51.74%.As bigger the tumor be,the metastasis ratios of levelⅠ,Ⅱ,Ⅲgot higher.No matter the location of the breast cancer, external or middel or internal part,the lymph node metastasis ratios had nonsense of statistics.The finding ratio and metastasis ratio of interpectoral lymph nodes were low.

Conclusion

Pay more attention to the dissection of level Ⅲlymph nodes,especially the ones who have get bigger tumors. The total axillary lymph node dissection should not be quitted. Do not judge whether the patients have ALNM by the breast cancer's location.The interpectoral lymph nodes should be dissected in the surgery therapy.
