Background: Aim was to analyze the impact of second-look surgery in the surveillance of T1 and T2 glottic cancer treated with CO2 laser.
Methods: Retrospective review of 98 patients treated between February 2005 and December 2022.
Results: Among 98 patients with early glottic cancer (T1/T2), 56 (57%) with suspected recurrence underwent a second-look surgery. Of all patients, 38 (38.77%) recurred 6 months after initial resection, 17 of which (45%) had a lesion in a different site from the primary. Of these 38 patients, 22 (58%) underwent laser surgery once, 12 (32%) underwent laser surgery twice, and 4 (10%) underwent laser surgery on three occasions during follow-up. The 5-year disease-free survival, 5-year survival, and larynx preservation rates were, respectively, 54%, 82%, and 90.8%.
Conclusions: Transoral resection is currently the first treatment option for early-stage glottic carcinoma because diagnosis and prompt treatment can be provided on an outpatient basis at the same time.
