BACKGROUND: Compare outcomes after surgery (S) or radiotherapy (RT) for T1a-T1b glottic squamous cell carcinoma (T1GSCC) in a population-based cohort study.
METHODS: Patients diagnosed with T1GSCC from 1999 to 2020 were identified from a public database. Clinical, demographic, and social data were extracted. Treatment and patient groups and subgroups were compared with log-rank test, Cox proportional test, and propensity-score matched (PSM).
RESULTS: Eight hundred and eighty-eight patients with T1GSCC were included in the study, with a median follow-up of 61 months. The 5- and 10-year overall survival (OS) S versus RT were 76% versus 71% and 60% versus 52% (p = 0.02), respectively. In the subgroup analysis, S was associated with better OS for T1b, male, and public service patients (p < 0.05). In the PSM cohort of S versus RT with 110 patients each, there was no significant difference in the OS, CSS, and LC.
CONCLUSIONS: T1GSCC has favorable outcomes with S or RT.
