声门上型喉鳞癌临床颈淋巴结阳性患者８１例，随机对照研究术前放疗４０Ｇｙ对控制颈部复发的意义。放疗加手术３２例，单纯手术４９例，随诊３年以上。颈部为复发的主要部位占６２．９％，放疗加手术组颈部复发率２１．８％，单纯手术组３０．６％，但无统计学差异（Ｐ＝０．９）。两组颈部复发率与Ｔ分期和Ｎ分期（除Ｎ＿３外）大小无明显关系。因此术前４０Ｇｙ对颈部复发无显著意义，建议对所有患者做临床阳性侧颈清扫术，术前放疗剂量提高到５０Ｇｙ，或术后放疗６０Ｇｙ以上。
81 cases of supraglottic laryngeal squamous cell carcinoma clinical cervical lymph node positive, a randomized controlled study of preoperative radiotherapy 40Gy on the control of neck recurrence significance. Radiotherapy plus surgery in 32 cases, 49 cases of simple surgery, followed up for 3 years. The main part of the neck for recurrence accounted for 62.9%, radiotherapy plus operation group neck recurrence rate of 21.8%, surgery alone group 30.6%, but no significant difference (P = 0.9). There was no significant correlation between the neck recurrence rate and the size of T stage and N stage (except N_3). Therefore, preoperative 40Gy neck recurrence was not significant, it is recommended for all patients with clinical positive lateral neck dissection, preoperative radiotherapy dose increased to 50Gy, or more than 60Gy postoperative radiotherapy.
