[Treatment and results of N1 supraglottic laryngeal carcinoma].
One hundred and eleven cases of supraglottic squamous cell cancer (T1-4N1) were retrospectively analysed. The result showed that: 1. the 3 years survival rate was 72% (80/111); 2, the rate of contralateral neck node metastasis after ipsilateral RND was 17.9%, and the cases of T3-4 with positive histologic findings of neck dissection samples had a higher rate contralateral neck node metastasis (38.6%); 3, the contralateral neck node metastasis rate (26.1%) in the group with surgery alone was significantly higher than that (7.1%) in the group with preoperative radiation (P < 0.05). The authors draw the conclusion that contralateral neck node metastasis is a high risk factor for recurrence of N1 supraglottic laryngeal cancer and that preoperative radiation may be be useful in controlling subclinical metastasis.
