Preliminary Results of Diode Laser Surgery for Early Glottic Cancer

Abstract

Objective To analyze the complications and preliminary oncologic results of microscopic diode laser surgery. Study Design Prospective research. Setting Ankara Oncology Education and Research Hospital. Subjects and Methods This prospective study was conducted on a series of 64 patients with glottic carcinoma (Tis, T1, T2) treated with microscopic endolaryngeal diode laser surgery. Results Four patients had local recurrence (6.2%). Local control and larynx preservation rates were 93.8% and 100%, respectively, for all groups of patients. Two-year disease-free survival after primary surgery was 100% for the Tis group, 96.4% for the T1 group, and 89.7% for the T2 group. When considering anterior commissure involvement, 2-year disease-free survival after primary surgery was 100% for the AC0 group, 85.7% for the AC1 group, and 85.7% for the AC2 group. Conclusion Our study of microscopic diode laser resection of Tis, T1, and T2 glottic tumors showed similar oncologic results to previous reports about CO2 laser surgery. In anterior commissure tumors, both techniques had high complication and recurrence rates.
