Abstract
The aim of this retrospective study is to evaluate the results obtained with CO2 TOLMS in patients with Tis, T1, and T2 glottic tumors at our Department from 2004 to 2016 treated with CO2 TOLMS. One hundred eighty-five patients having a median age of 67 years (range 42–88) were included in the present analysis. The tumor stages of the patients included 134 pTis-T1a, 12 pT1b, and 39 pT2 cases. Median duration of follow-up for the whole study cohort was 55 months (range 24–108 months). At 5-year follow-up, local control was 91%, 83%, and 79.4% for T1a, T1b, and T2 respectively. Disease-specific survival was 95.5%, 91.6%, and 92.3%. Overall survival was 73.8%, 91.6%, and 82%, and larynx preservation was 96.2%, 83%, and 84.6%. This study confirms that CO2 TOLMS is a safe and standard therapy for selected T1 and T2 glottic carcinoma, and our review on T2 glottic cancer suggests that CO2 TOLMS represents a reliable option in terms of overall survival, disease-specific survival, and laryngeal preservation. However, patients with anterior commissure involvement and T2 cancer should be evaluated with a preoperative MRI in order to exclude the infiltration of the laryngeal framework and to quantify the neoplastic involvement of para-glottic space.
