목적: The aim of this study was to evaluate the oncologic, functional outcomes and long-term result of laryngeal squamous cell carcinomas treated patients who underwent supracricoid partial laryngectomy (SCPL). 방법:Data from 153 glottic cancer patients who received SCPL at Seoul St. Mary's Hospital from 1993 to 2020 were prospectively analyzed. The extended type was performed on 32 patients and the unextended type on 12 patients. CHEP was performed on 11 patients and CHP was performed on 4 patients. The oncologic and functional outcomes of these patients were investigated and analyzed. 결과:The NG tube removal time after surgery was 26.1 days for nonextended type and 31.3 days for extended type (p=0.25). The decannulation time was 22.0 days and 37.7 days (p=0.05). The history of PEG was seen in 15 patients (9.8%). 5 patients over age 70 had a PEG (16%), and 10 patients under age 70 (8%) experienced a PEG. Aspiration pneumonia was experienced by 16 patients (10%). 8 patients (26%) over age 70, and 8 patients (6.5%) under age 70. The study subjects showed a socially serviceable voice after surgery. The 5-year survival rate was 82% for unextended type and 80% for extended type (p=0.09). The entire 3- year/5-year DFS was 87% and 84%. The DFS according to T stage, 67%/65% for T3 (n=43), 75%/62% for T4 (n=32). Advanced T stage (p=0.03), Paraglottic space invasion (p=0.001), Perineural invasion (p=0.001), Lymphatic invasion (p=0.007), Extranodal extension (p=0.02) significantly contributed to 5-year survival rate. 결론:In the case of SCPL, the outcome was oncologic and functionally excellent. Both PEG and aspiration pneumonia show age dependency, and it is thought to show a more distinct association with aspiration pneumonia. The disease free survival rate was lower in the advanced stage. Advanced T stage, paraglottic space invasion, perineural invasion, lymphatic invasion and extranodal extension were found to be factors affecting the 5-year survival rate.
