Impaired vocal cord mobility in T2N0 glottic carcinoma: Suboptimal local control with Radiation alone.

Background: T2 glottic cancer with impaired vocal cord mobility (T2b) is known to have higher local failure rates when compared with T2 cancers without impaired cord mobility (T2a) treated with radiotherapy (RT) alone.

Methods: In this retrospective review, we identified and compared the local control rates of 3 groups: T2aN0 treated with RT; T2bN0 treated with RT; and T2b-3N0-2 treated with chemoradiotherapy (CRT).

Results: The 3-year local control rate was 95.
