Abstract
Background
To evaluate clinical outcome and functional larynx preservation after radiotherapy (RT) for adenoid cystic carcinoma (ACC) of the larynx.
Methods
Eleven patients with primary ACC of the larynx, who received RT definitely (n = 5/11) or postoperatively (n = 6/11), were analyzed regarding survival and treatment‐related toxicity with the focus on functional larynx preservation.
Results
Median follow‐up was 45 months. RT offered an excellent 5‐year local control (LC) rate of 100%. Eight of 11 patients were treated with a laryngeal preservation approach (LPA). At last follow‐up, only one of these eight patients developed a local recurrence requiring a total laryngectomy 11 years after treatment. Severe toxicity was uncommon, with only one patient with LPA, requiring a temporary tracheostomy during therapy.
Conclusions
RT is an effective treatment method for laryngeal ACC with excellent LC rates, preservation of the laryngeal function and voice formation, representing a valuable therapy alternative to total laryngectomy.
