前哨淋巴结是指肿瘤淋巴引流区域的第一站淋巴结 ,是区域淋巴结中最容易被肿瘤侵犯的淋巴结。通过对前哨淋巴结的病理检查 ,可以预测整个淋巴引流区域是否受到肿瘤侵犯。在黑色素瘤和乳腺癌的大量临床研究中已经肯定了前哨淋巴结活检技术的准确性和可行性。其它实体瘤的临床研 Sentinel lymph node refers to the first station lymph node in the lymphatic drainage area of ​​the tumor. It is the lymph node most likely to be invaded by the tumor in regional lymph nodes. Through the pathological examination of sentinel lymph nodes, it can be predicted whether the entire lymphatic drainage area is affected by the tumor. The accuracy and feasibility of sentinel lymph node biopsy have been confirmed in a large number of clinical studies of melanoma and breast cancer. Clinical research of other solid tumors
