【摘要】:舌鳞状细胞癌位居口腔癌首位,颈淋巴结转移妨碍其治疗。颈淋巴结转移分为微转移和包膜外转移,前者与肿瘤预后较差相关,后者对患者的生存率影响更大。舌鳞状细胞癌的淋巴结转移多为Ⅰ~Ⅲ区,原发灶浸润深度对颈部隐匿性淋巴转移有较高的预测价值。舌鳞状细胞癌颈淋巴结转移存在着一定的规律性,与其病理分级、神经和血管侵犯、浸润深度等多方面因素相关。颈淋巴结转移的临床评估除需借助B超、CT、磁共振成像、正电子发射断层摄影术等影像学辅助检查技术外,还需借助细胞细针吸取活检和前哨淋巴结活检来确认。迄今有关舌鳞状细胞癌的颈淋巴结处理仍无定论,临床选择上存在着仁者见仁智者见智的现象。目前,舌鳞状细胞癌的颈淋巴结处理主要为颈淋巴结清扫和随访观察两种方式,早发现、早诊断、早治疗仍是解决其问题的主要方式。
