Objectives: To determine if anterior commissure (AC) involvement in glottic cancer (GC) is a prognosis factor to recurrence and 5-year survival rate. Study design: Observational retrospective. Methods: Assessment of medical files of patients who were diagnosed with GC with T1a and T1b staging during a 12-year period (2010-2021). Results: Twenty-three patients (67,6%) were classified with T1a stage (10 cases with AC involvement) and 11 patients (32,4%) with T1b staging (7 cases with AC involvement). AC involvement was associated with higher risk of recurrence for T1b cases (p<0,05), but not for T1a cases. Five-year mortality rate had no significant statistically difference. Conclusions: AC involvement was a negative prognostic factor in local disease control during follow-up, thus raising the possibility of AC inclusion in T staging in glottic tumors.
