摘要
对１４７例双侧或对侧无临床淋巴结转移（ｃＮ０）的声门型喉癌作了颈显微转移和迟发转移观察。结果显示Ｔ１～Ｔ４双侧ｃＮ０的同侧显微转移率分别为０／１、２２．５％、３１．６％和３７，５％，平均２６．３％；同侧迟发转移率分别为１／３、２／１１、２／６和２／３，平均３０．４％；对侧迟发转移率分别为０／４、６．１％、８．０％和１８．２％，平均７．９％。Ｔ２～Ｔ４对侧ｃＮ０的对侧迟发转移率分别为９．５％、２６．１％和２８．６％，平均１９．６％。此数据对于决定ｃＮ０者是否行预防性颈廓清术有重要参考意义。
Abstract Micrometastasis and delayed metastasis were investigated on 147 cases of bilateral or contralateral clinically N0 neck of supraglottic carcinoma.The results showed that in bilateral clinicallv N0 neck,the rate of ipsilateral micrometastasis from T1 to T4 was 0/1,22.5%,31.6%and 37.5%respectively 1 with a mean of 26.3%;the rate of ipsilateral delayed metastasis was 1/3,2/11,2/6 and 2/3 respectively,with a mean of 30.4%:the rate of con-tralateral delayed metastasis was 0/4,6.1%,8.0%and 18.2%respectively,with a mean of 7.9%.In contralateral clinically N0 neck,the rate of delayed metastasis from T2 to T4 was 9.5%,26.1%and 28.6%respectively,with a mean of 19.6%,These data would be of importance in deciding whether a preventive neck dissection should be done or not in clinical-ly N0 neck
