Abstract

Objectives/Hypothesis: Evaluate the oncologic outcomes of patients with early and select advanced primary glottic squamous cell carcinoma (SCCa) managed by transoral laser microsurgery (TLM). Study Design: Retrospective cohort study. Methods: Ninety cases of TLM-managed primary glottic SCCa were identified retrospectively using a prospectively collected database. Results: Outcomes of patients with pTis–pT2a disease (n = 65) and pT2b–pT4a disease (n = 25) were, respectively: 5-year local control, 86.2% and 67.5%; 5-year disease-free survival, 64.9% and 44.9%; 5-year disease-specific survival, 96.4% and 59.0%; laryngeal preservation, 96.9% and 80%. Five of nine patients (56%) with supraglottic–glottic–subglottic tumors were local recurrence-free compared to the 70 of 81 (86%) patients with glottic, supraglottic–glottic, and glottic–subglottic tumors. Seven of 13 patients (54%) with positive or indeterminate margins were local recurrence-free compared to 68 of 77 (88%) patients with negative margins. Conclusions: Given sample size considerations, this study highlights the satisfactory oncologic outcomes of TLM-treated glottic cancer and the potential importance of margin management and disease extension within the larynx.
