Abstract:
Objective: To explore the efficacy of transoral CO2 laser microsurgery in patients with early laryngeal carcinoma. Methods: Total of 186 patients with stages TisN0M0-T3N0M0 glottic or supraglottic laryngeal cancer between April 2003 and April 2008 were retrospectively collected. All of these patients received CO2 laser microsurgery. The clinical records and the follow-up information were analyzed. Results: The overall 3-year survival rate was 96.3%, 3-year local control rate was 87.7%, and 5-year local recurrence rate was 3.7%; the overall 5-year survival rate was 92.0%, 3-year local control rate was 77.8%, and 5-year local recurrence rate was 22.6%; the rate of lymph node metastasis was 9.1%. Conclusion: As the first choice for T1-2 glottic and supraglottic laryngeal cancer, transoral CO2 laser microsurgery can excise tumor correctly with the larynx being preserved, having a good long-term outcome. However, for advanced laryngeal cancer and supraglottic laryngeal cancer, transoral CO2 laser microsurgery should be carefully considered. Copyright © 2013 by TUMOR.
