Abstract

Background: Carcinoma of the supraglottic larynx is a relatively common malignancy treated with either surgery, radiotherapy, or a combined approach.

Methods: The radiotherapy records of 190 patients with carcinoma of the supraglottic larynx treated at the Massachusetts General Hospital (MGH) and Massachusetts Eye and Ear Infirmary (MEEI) from 1981 to 1992 were reviewed. Of these patients, 164 were available for evaluation for local control and 169 for disease-specific survival. The patients were treated with accelerated hyperfractionated radiotherapy to 67.2-72 Gy/1.6 Gy per fraction twice a day in 6 weeks. The median follow-up was 56 months. Five-year actuarial local and regional control, relapse-free and overall survival, and voice-preservation rates were analyzed.

Results: For T1, T2, T3, and T4 tumors, local control rates were 96%, 86%, 76%, and 43%, respectively (p < .01), and the corresponding relapse-free survival rates were 78%, 82%, 64%, and 40% (p < .01). For the patients with N0, N1, and N2-3 disease, local control rates at the primary site were 86%, 74%, and 46%, respectively (p < .01), and the corresponding relapse-free survival rates were 79%, 53%, and 39% (p < .01). Including surgical salvage, the ultimate local control rates were 96%, 93%, 88%, and 51%, respectively (p < .01). Voice preservation rate for the entire group was 79% and for T1, T2, T3, and T4 tumors, rates were 96%, 80%, 72%, and 43%, respectively.

Conclusions: Our experience with accelerated hyperfractionated radiotherapy for supraglottic carcinoma showed excellent locoregional control, relapse-free survival, and laryngeal preservation. The radiation toxicity was acceptable. The T and N stages were significant predictors of outcome, and the T4 tumors and node-positive neck disease portended a poor prognosis and therefore should be considered for protocols that include adjuvant therapies.
