title: [Epithelioma of the pyriform sinus: retrospective study and survival analysis after 5 years].
abstract: We have studied 27 clinical records of patients with piriform sinus epidermoid carcinoma diagnosed and treated in our department during a period of 6 years. All the patients underwent surgery and radiotherapy. We have analyzed the survival and recurrence rates together with other parameters that may have some influence in them. We have tried to show the factors that might be in relation with the prognosis of pyriform sinus carcinoma. The statistical analysis show a survival rate of 29.6% after 5 years follow up, being the node invasion, wither clinical or histological, the main fact to have a prognostic value.
