Abstract
BACKGROUND: The lack of standardized treatment is problematic in laser surgery for laryngeal cancer, and may result in an increased recurrence rate. This study analyzed the prognosis of early laryngeal carcinoma after different types of cordectomy with laser surgery.
METHODS: A cohort of 818 patients with stage Tis or T1 primary early glottic squamous cell carcinoma treated with CO2 laser surgery was retrospectively analyzed.
RESULTS: Of the 818 patients, According to the Kaplan-Meier method, the rate of 5-year overall survival was 92.8%, and the rates for 5-year disease-specific survival and 5-year locoregional control were 96.9% and 91.3%, respectively. Among the T1 patients, type II cordectomy with laser surgery had a significant impact on the 5-year locoregional control rate, but no obvious impact on the 5-year overall survival rate.
CONCLUSIONS: There must be sufficient depth and extent of excision in T1 patientsand in early carcinoma especially those with possible microinvasive carcinoma.
