Clinical assessment of the irradiated larynx

Abstract

AbstractFollowing radiotherapy for squamous carcinoma of the larynx, it may be impossible to differentiate occult persisting tumour from irradiation effects, possibly with chondroradionecrosis, even after repeated biopsy. In seven of the cases presented, post-treatment laryngectomy failed to provide histological evidence of residual or recurrent carcinoma, which clinical examination has indicated. None-theless, total laryngectomy was performed, subsequently revealing tumour in five of the seven excised larynges. The two tumour-free larynges were associated with cervical metastases. The clinical indications of persisting tumour, the factors compromising post-irradiation evaluation and the role of diagnostic aids are discussed.
