Critical appraisal of watchful waiting policy in the management of N0 neck of advanced laryngeal carcinoma

Abstract

Objective: To analyze the problem of nodal recurrence of N0 neck advanced laryngeal carcinoma. Design: Retrospective analysis. Setting: Hospital referral center. Patients: One hundred thirty-three patients with cancer stages T3-T4, N0, M0 who had total laryngectomy between January 1981 and December 1990. Main Outcome Measure: Nodal recurrence. Results: Of the 11 patients who had elective radical neck dissections, there was no nodal recurrence. Of the other 122 patients who had no elective neck dissection, 19 patients (16%) developed nodal recurrence and all nodal recurrence was at levels II, III, and IV. Twelve patients (63%) underwent salvage radical neck dissection for nodal recurrence and they had a 38% adjusted 5-year actuarial survival rate. Of these 122 patients who had no elective neck dissection for the N0 neck, 12 patients (10%) eventually died of nodal recurrence. Conclusion: The watchful waiting policy is a satisfactory management option of N0 neck of advanced laryngeal carcinoma.
