舌鳞状细胞癌 (简称舌鳞癌 )的颈淋巴结转移率较高 ,据国内文献报告为 2 8.81%～ 37.1% 〔1 ,2〕国外文献报告为 2 8%～ 36 %〔3,4〕。舌鳞癌治疗失败的主要原因是颈部淋巴结的转移 ,甚至在一些早期舌鳞癌患者无颈部淋巴转移的临床症状时 ,亦可发生潜在的颈部淋巴结转移。因此 Tongue squamous cell carcinoma of the tongue (tongue squamous cell carcinoma) has a high rate of cervical lymph node metastasis, according to the domestic literature reported 2 8.81% ~ 37.1% 〔1, 2〕 foreign literature reported 28% ~ 36% 〔3,4〕 . The main reason for the failure of tongue squamous cell carcinoma is the metastasis of cervical lymph nodes, and even cervical lymph node metastasis may occur in some patients with early tongue squamous cell carcinoma without clinical symptoms of cervical lymphatic metastasis. therefore
