T3 and T4 carcinoma of the larynx--a retrospective study.

T3 and T4 lesions of the larynx were reviewed and the five year survival figures compared for radiotherapy, surgery, and combined therapy. Glottic T3N0M0 lesions gave an acceptable five year survival figure of 66 per cent. Radiotherapy is advised as the modality of treatment for T3N0M0 lesions. Larger glottic and supraglottic lesions responded poorly to all modalities of treatment and a more aggressive treatment policy may be advisable.
