Abstract

Conclusions. Our study suggests that routine level I dissection may not be necessary in the surgical management of clinically N + hypopharyngeal squamous cell carcinoma (SCC) in patients who do not have a positive lymph node in neck level I. Objective. To determine whether level I lymph node dissection can be saved in patients with clinically N + hypopharyngeal SCC. Patients and methods. Retrospective analysis of 64 consecutive clinically N + patients with untreated hypopharyngeal SCC between 1994 and 2006. Forty-seven patients underwent level I lymph node dissection and the remaining 17 did not. Forty-five of the 64 patients were followed for a minimum of 2 years, if alive, or until death. Of these 45 patients, 35 underwent ipsilateral level I dissection of the neck. Results. The incidence of occult metastases to level I was 6% (3 of 47). Six (17%) of 35 patients with level I dissection and 1 (10%) of 10 patients without level I dissection experienced regional recurrence (p>0.05). The 2-year disease-specific survival in 47 patients undergoing level I neck dissection was 44% compared with 37% in 17 patients who did not undergo level I neck dissection (p>0.05).
