Transoral Laser Microsurgery With Neck Dissection Versus Radiotherapy for T2N0 Supraglottic Cancer.

Abstract

To compare overall survival outcomes associated with transoral laser microsurgery (TLM) with neck dissection versus definitive radiotherapy in the management of T2N0 supraglottic squamous cell carcinoma. Data were extracted from the National Cancer Database concerning patients with cT2N0M0 supraglottic cancer treated with either TLM and neck dissection with minimum lymph node yield of 10 or definitive radiotherapy. Predictors of overall survival were assessed via Cox proportional hazards regression. Seventy-six cT2N0 supraglottic squamous cell carcinoma patients who underwent TLM with neck dissection (+/- adjuvant therapy) versus 991 patients who underwent radiotherapy. TLM was associated with an overall survival benefit (OR = 0.574; 95% CI 0.383-0.860) compared with radiotherapy. There was no difference in survival between TLM patients receiving adjuvant treatment and those receiving definitive radiotherapy. An up-front, TLM-based surgical approach to cT2N0 supraglottic cancer may offer an overall survival benefit compared with definitive radiotherapy, and should receive more frequent consideration as a primary approach to this disease process. 3 Laryngoscope, 133:601-606, 2023.
