Multivariate analyses of prognostic factors were carried out in 1 252 consecutive patients with laryngeal squamous cell carcinoma treated with primary radical radiotherapy. Ten percent of patients had positive neck nodes. Most of the patients were in stage I (48%), the remainder in stage II (24%), III (18%) and IV (10%). Of these patients, 746/1 252 (60%) were controlled by primary treatment but 506/1 252 (40%) had residual tumor or recurrent disease. The larynx was preserved in 62% of patients. The 5-year actuarial values for disease-specific and overall survival were 78% and 60%, respectively. The results of a univariate analysis showed multiple significant prognostic factors, and in a Cox proportional hazards model it was found that gender and T-classification were significant for T-failure, locoregional failure, death from cancer and death from all causes. The region of origin, nodal involvement, differentiation and pretreatment hemoglobin value were significant for several of the above-mentioned endpoints. Laryngeal carcinoma is curable when treated with primary radiotherapy, and this treatment confers a high degree of organ preservation. Independent prognostic factors in the multivariate analyses were gender, region of origin, T-stage, nodal involvement, differentiation and hemoglobin.
