Abstract:
Background: Neck lymph node status is the chief prognostic index in patients with head and neck squamous cell carcinoma (SCC), yet the management of a clinically negative neck in this setting is still controversial, especially in patients with laryngeal SCC (LSCC). Objectives: To evaluate the efficacy of selective neck dissection (SND) to control occult disease in patients with LSCC and clinically negative (cN0) necks. Materials and methods: Medical records of 1476 patients with cN0 LSCC were analyzed. In conjunction with primary treatment, 126 (8.5%) underwent at least unilateral elective neck dissection, whereas most 1350 (91.5%) followed a wait-and-see protocol. Prognostic significance was indicated by the Kaplan-Meier survival estimates. Results: The rate of occult neck disease was 15%. Five-year overall and disease-free survival rates were 74.4% and 66.7%, respectively. Prognosis was closely related to T stage, preoperative tracheotomy, and postoperative recurrence. There was no significant correlation with age, sex, or preoperative neck dissection; but in patients with supraglottic LSCC, the relation between prognosis and preoperative neck dissection was significant, with fewer neck and local recurrences than the wait-and-see group (p < .05). Conclusions and significance: Selective neck dissection is serving as an accurate prognostic tool in patients with supraglottic laryngeal cancers.
