颈部淋巴结转移癌一旦和周围组织固定,则预后不良,如口腔肿瘤病人的颈淋巴结活动度减小者,5年存活率是40%,而完全固定者只有13%。然而,有关颈部固定淋巴结方面的专著极少,对“固定”一词解释亦存在分歧,致使颈部固定淋巴结发病率的报道差别很大,从5%到35%不等。“固定”应是指淋巴结与周围结构如下颌骨、颈动脉、颈深部肌肉、锁骨、颈部皮肤等发生粘连;有一些学者认为“固定”是指活动度的减小。AJC现在已不用59年癌症分期法中 Once the cervical lymph node metastasis is fixed with the surrounding tissue, the prognosis is poor. For example, patients with oral cancer have reduced cervical lymph node activity, the 5-year survival rate is 40%, and only 13% is completely fixed. However, there are few monographs about the fixed lymph nodes in the neck, and there are differences in interpretation of the term “fixed”, resulting in reports of the incidence of cervical lymph nodes that vary widely, ranging from 5% to 35%. “Fixed” should refer to the adhesion of lymph nodes to the surrounding structures such as jaws, carotids, deep neck muscles, clavicles, neck skin, etc.; some scholars believe that “fixed” refers to a decrease in activity. AJC is now free of 59 years of cancer staging
