AIMS: To investigate prognostic factors for survival and locoregional control in patients with stage I-IVA hypopharyngeal cancer treated with laryngeal preservation radiotherapy. METHODS: This study was a retrospective analysis of 108 patients with stage I-IVA squamous cell carcinoma of the hypopharynx, treated with laryngeal preservation radiotherapy. Actuarial survival, disease-specific survival and local relapse-free survival were calculated, and multivariate analyses were performed using Cox's proportional hazards model. RESULTS: After a median follow-up duration of 39 months, the five-year local relapse-free survival rate was 35 per cent for all patients, 66 per cent for those with stage I-II disease, 46 per cent for those with stage III disease and 20 per cent for those with stage IVA disease (p = 0.004). Multivariate analyses showed that tumour and node stages were independent prognostic factors. CONCLUSIONS: Patients with stage I-II disease were suitable for laryngeal preservation radiotherapy. For most patients with stage III-IVA disease, other than those who were T1 N1 or T2 N1, the treatment results were poor.
