Abstract
OBJECTIVE: To determine if the clinical behavior of T1 glottic squamous cell carcinoma varies by its location on the medial free edge or upper aspect of the vocal cords.
STUDY DESIGN: Retrospective cohort.
SETTING: Single tertiary university-affiliated medical center.
SUBJECTS AND METHODS: Clinical, treatment, and outcome data were collected for 104 patients with T1N0M0 glottic squamous cell carcinoma who were treated and followed at our center in 1995-2013. Findings were compared between those with a tumor on the medial (n=60, 57.7%) or superior (n=44, 42.3%) aspect of the cords.
RESULTS: Mean follow-up time was 4.15years. No between-group differences were found in demographic or risk factors. There was a significant association of anterior commissure involvement with disease recurrence (P=0.0012) and of superior (vs medial) location with higher rates of anterior commissure involvement (P<0.001) and recurrence (P=0.01) and shorter time to recurrence (P<0.001).
CONCLUSIONS: T1 squamous cell carcinomas on the superior aspect of the vocal cords have a poorer prognosis than medial tumors and should be closely monitored for recurrence.
