BACKGROUND: Modest survival rates are published for treatment of oral squamous cell carcinoma (OSCC) using conventional approaches. Few cohort studies are available for transoral resection of OSCC. METHODS: Analysis for recurrence, survival, and prognosis of patients with OSCC treated with transoral laser microsurgery (TLM) ± neck dissection was obtained from a prospective database. RESULTS: Ninety-five patients (71 patients had stages T1-T2 and 24 had stages T3-T4 disease) with minimum follow-up of 24 months met criteria and demonstrated negative margins in 95%. Five-year local control (LC) and disease-specific survival (DSS) were 78% and 76%, respectively. Surgical salvage achieved an absolute final locoregional control of 92%. Immune compromise and final margins were prognostic for LC, whereas T classification, N classification, TNM stage, comorbidity, and perineural invasion were also significant for DSS. CONCLUSION: We document a large series of patients with OSCC treated with TLM, incorporating T1 to T4 primaries. A significant proportion of stage III/IV cases demonstrates feasibility of TLM in higher stages, with final margin positivity of 5%, LC greater than 90%, and comparable survival outcomes.
