title: Supraglottic carcinoma treatment results analysed by therapeutic approach.
abstract: This study reviewed 161 patients with supraglottic squamous cell carcinoma who underwent radical therapy at Kurume University Hospital between 1989 and 2003. The five-year survival rate was 89 per cent in patients with stage III disease and 75 per cent in stage IV patients, thus demonstrating favourable results even for patients with advanced cancer. The five-year local control rate and the laryngeal preservation rate were poor in patients with T3 tumours (being 75 per cent for both), but the overall five-year local control rate for all patients was 86 per cent. Laser surgery plus chemo-radiotherapy was the most frequently used treatment. The local control rates and laryngeal preservation rates were poor in patients with tumour infiltration to the glottis and the laryngeal ventricle. In conclusion, the indications for combination laser therapy for supraglottic carcinoma should in future be extended, and the type and number of chemotherapy courses for this cancer should be further clarified.
