Abstract
PURPOSE: This study aimed at determining the importance of an elective neck dissection (END) in case of a cN0 laryngeal or hypopharyngeal carcinoma after (chemo) radiation. METHODS: Retrospective review was made of patients treated in a single tertiary center between 2002 and 2014. Influence of an END in case of a cN0 salvage laryngectomy on complications, recurrence-free survival and disease-specific survival was assessed. INCLUSION CRITERIA: squamous cell carcinoma and cN0 neck. EXCLUSION CRITERIA: second primary tumor in the head and neck, a total laryngectomy because of a dysfunctional larynx, or a previously performed neck dissection. RESULTS: Of the 86 included patients, 27 (31%) underwent an END, of which 1 had occult metastasis (4%). Of the remaining 59 patients (69%) without an END, 3 developed a regional recurrence (5%). The overall survival was significantly higher for patients who had an END (p = 0.037). The incidence of complications was not significantly different between the two groups. CONCLUSIONS: In light of the limited complications of an END and the poor prognosis of regional recurrence after previous (chemo)radiotherapy and a (pharyngo)laryngectomy, we advise consideration of an END at the time of a salvage laryngectomy.
