ABSTRACT
Objective To study the efficacy and safety of CO2 laser microsurgery for early glottis carcinoma.Methods The data of 96 cases of early glottic laryngeal carcinoma treated with CO2 laser microsurgery were retrospectively analyzed.Surgical specimens were conventionally embedded with paraffin and serially sectioned.Sections were stained by using hematoxylin-eosin for pathologic examination.The local control rate was observed after operation.Results Among the 96 specimens,88 surgical margins were negative and 8 were positive.10 patients (10.4 %) recurrenced followed up for 3 years.The recurrence rates of Tis,T1a,T1b and T2 were 0 (0/10),4.1% (2/48),25.0 % (4/16) and 18.1% (4/22),respectively,with significant differences among groups (X2 =6.105,P < 0.05).All of 8 cases with positive margin and 2 cases with negative margin were recurrened.The recurrent rate of patients with involvement of the anterior commissure was 30.0 % (6/20),which was higher than that of patients with no tumor invasion [5.3 % (4/76)] (X2 =9.624,P < 0.01).Conclusions The safe edges can be obtained by CO2 laser microsurgery for early stage of glottis carcinoma,which have advantages in local control rate,vocal function of the larynx and curative effect.
