영문 초록

Background: Supraglottic and hypopharyngeal regions drain into the upper deep cervical lymph nodes. And bilateral neck node metastasis is frequently occured especially, in the early stage. It influences on the prognosis of above diseases. The prognosis for patients wih supraglottic and hypopharyngeal cancers, although usually poor, has improved by modern imaging technique, better application of treatment modalities, increasing assortment of reconstructive procedures and improved application of radiation therapy. Objectives: This study was designed to obtain objective data about the patterns of neck node metastasis and to identify the necessity of elective bilateral neck dissection. Material and Methods: Twenty four patients with supraglottic cancer and twenty six patients with hypopharyngeal cancer were investigated from the chart review. Results: In supraglottic cancer, the most frequent sites of neck metastasis is level II (52.9%) and level III (52.9%) in ipsilateral side, level II (29.4%) in contralateral side, in hypopharyngeal cancer, level II (73.7%) and III (52.6%) in ipsilateral side, level II (10.5%) in contralateral side. In elective neck dissection, the occult metastasis is about 50% in supraglottic cancer, but there is no occult metastasis in hypopharyngeal cancer. Conclusion: In supraglottic cancer, elective bilateral neck dissection is necessary because of early contralateral neck metastasis, but in hypopharyngeal cancer, elective contralateral neck dissection may not be always necessary because of rare occult metastasis and contralateral neck metastasis.
