乳腺癌腋下前哨淋巴结优势转移通道的研究

Study on the prior metastatic channel of the axillary sentinel lymph node metastasis in breast cancer

目的探讨乳腺癌腋下前哨淋巴结转移的特点。方法分析湖州市中心医院2018年1月至2020年8月腋窝临床阴性患者共194人,术前15分钟将l%亚甲蓝4ml注射于外上象限皮下组织及乳晕和腺体内的方法检测前哨淋巴结,选取前哨淋巴结活检成功且淋巴结转移1~2枚共48例。结果发现乳腺深浅淋巴管有各种独立的前哨淋巴结,而不是以往认为的深浅淋巴管引流至共同淋巴结。而且深部淋巴管引流的淋巴结较浅的更加容易发生转移,有统计学意义。结论乳腺深浅淋巴管引流至各独立前哨淋巴结,且深组淋巴结更加容易发生转移。

Objective TTo investigate the characteristics of axillary sentinel lymph node metastasis in breast cancer.Methods A total of 194 patients with clinically negative axillary nodes in our hospital from January 2018 to August 2020 were analyzed.Sentinel lymph nodes were detected by injecting 1%methylene blue 4ml into the subcutaneous tissue in the outer upper quadrant,the areolar and the parenchyma.A total of 48 patients with 1~2 positive lymph node were selected.Results There were various sentinel lymph nodes in the deep and superficial lymphatic vessels of the mammary gland.In addition,the deep lymph nodes were more prone to metastasis,which was statistically significant.Conclusion There are separate sentinel lymph nodes in the deep and shallow lymphatic vessels,and the lymph nodes in the deep group are more prone to metastasis.
