Results of laryngeal cancer surgery in four ENT centers in poland.

The results of laryngeal cancer surgery were assessed in a group of 832 patients treated in four major ENT centers in Poland. Five-year survival rates were as follows: stage I, 86%; stage II, 71%; stage III, 54%; and stage IV, 42%. In experienced hands and for properly selected cases, cure rates after partial (conservation) laryngeal surgery were similar to those after total laryngectomy. For early stages (I and II), the survival after partial surgery was better than that found after radiotherapy.
