Abstract

Objective: To evaluate the curative effect of CO2 laser in treatment of glottic carcinoma.

Methods: Retrospective analysis of 217 cases of early glottic laryngeal carcinoma treated with laser surgery were carried out. Among these cases, Tis were 22 cases, T1a 108 cases, T1b 38 cases, T2 46 cases, T3 3 cases. 1 case being applied vocal cord excision due to failure of tumor exposure. The follow-up period was 3 to 9 years.

Results: Relapse were detected in 21 out of 217 cases of glottic laryngeal carcinoma after CO2 laser surgery under self-retaining laryngoscope. The recurrent rate was 9.7% (21/217). Recurrent ratio of T1a, T1b, T2, T3 were 5.6% (6/108), 21% (8/38), 13.0% (6/46), 1/3 respectively, with significant differences among groups (chi 2 = 6.102, P < 0.01). The recurrent rate was 21.6% of tumors offended the anterior commissure, versus 5.1%(8/157) with no involvement of anterior commissure (chi 2 = 13.64, P < 0.01). 217 cases received laser surgery as the only treatment, 201 cases were still alive. 4 failed to be followed-up(taken into dead number), 12 cases were dead. 3 year survival rate was 97.2%(211/217), 5 year survival rate was 89.4%(118/132).

Conclusion: It was reliable to use laser surgery in treatment of early glottic laryngeal cancer. The advantages of it included lower complication rate and vocal function was well retained.
