BACKGROUND: Early glottic cancer can be cured with transoral laser resection, but in cases with anterior commissure involvement, there is still controversy concerning the best treatment modality. METHODS: The impact of anterior commissure involvement on local control was analyzed in a retrospective review of 444 patients with early glottic cancer (pT1a-pT2a) treated between 1986 and 2004 with transoral laser microsurgical resection. RESULTS: The anterior commissure was involved in 153 cases; the 5-year local control rate with and without anterior commissure involvement was 73% versus 89% for T1a and 68% versus 86% for T1b tumors. For T2a lesions, the 5-year local control rate was 76%, irrespective of anterior commissure involvement. CONCLUSION: In early glottic cancer treated by transoral laser microsurgery, a decrease in local control is evident in case of anterior commissure involvement for T1a and T1b but not for T2a tumors.
