Long-term outcome of CO₂ laser microlaryngoscopic treatment for laryngeal cancer / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the long-term outcome of CO₂ laser microsurgery for laryngeal cancer.</p><p><b>METHODS</b>Seventy patients with laryngeal cancer were treated with CO₂ laser microsurgery. All patients were followed up for at least 36 months (36 - 108 months).</p><p><b>RESULTS</b>During the 36-108 months follow-up, 64 patients were alive, and 6 patients died of recurrence. The total 5-year survival rate was 91.4%, 5-year local control rate was 81.4%, 5-year local recurrence rate was 18.6%, and the neck metastasis rate was 4.3%. All survivals had normal breathing and good phonation.</p><p><b>CONCLUSIONS</b>The long-term outcomes of CO₂ laser microsurgery for laryngeal cancer are good, with rapid recovery and few complications, well protected laryngeal function and quite good quality of life. Laser surgery should be the priority of treatment for early stage laryngeal cancer. However, laser surgery for advanced laryngeal cancers and supraglottic laryngeal cancers should be carefully chosen.</p>
