Lionello M, Bertolin A, Nardello E, et al. - Researchers investigated the prognostic significance of thyroarytenoid (TA) muscle involvement in early glottic cancer treated with transoral laser microsurgery (TLM). Reviewing a cohort of 209 patients consecutively treated with TLM for early glottic carcinoma, they observed a significant correlation of TA muscle infiltration with a worse prognosis in terms of recurrence rate and disease-free survival. Findings support considering it as a criterion for upstaging glottic cancer from pT1 to pT2.
