PURPOSE: Laser cordectomy is a widely accepted treatment modality for selected cases of early glottic cancers, but its role as a salvage treatment remains unclear. We aimed to investigate the oncological outcomes and failure patterns of salvage cordectomy.
MATERIALS AND METHODS: This was a retrospective cohort study of patients who underwent cordectomy for early glottic cancer between 2013 and 2022 at a tertiary referral center. The main outcome measures were overall survival, larynx-preservation rate, tracheostomy dependency rate, and disease-free survival.
RESULTS: A total of 142 patients (mean age: 63 years, interquartile range [IQR]: 45-72, 123[86.9 %] males) were analyzed. There were 38 (26.8 %) recurrences after a mean of 22 months (IQR: 17-26). Among them, 25 (17.6 %) underwent salvage cordectomy, while 13 (9.1 %) received other salvage treatments (11[7.7 %] (chemo)radiotherapy and 2[1.4 %] total laryngectomy). In comparison to the other salvage treatments, salvage cordectomy demonstrated lower tracheostomy rates (0 vs. 31 %, p = 0.05), comparable 5-year disease-free survival (62 % vs. 54 %, p = 0.4), higher 5-year larynx preservation rate (92 % vs. 54 %, p = 0.02), and improved 5-year overall survival rate (84 % vs. 62 %, p = 0.01). Factors associated with salvage cordectomy failure were age >60 years (odds ratio [OR]: 1.3, 95 % confidence interval [CI]: 1.15-1.53), smoking continuation (OR: 3.73, 95 % CI: 3.5-4.4), heavy smoking (OR: 1.24, 95 % CI:1.07-2.15), and pT1b + (OR: 2.26, 95 % CI: 2.1-2.9).
CONCLUSIONS: Salvage cordectomy offers favorable larynx preservation rates and oncological outcomes for recurrent disease amenable to conservative surgery. Smoking, advanced age, and advanced tumor stages are associated with salvage cordectomy failure.
