[Esthesioneuroblastoma: experience from 4 cases treated with radiotherapy and neoadjuvant chemotherapy].

The esthesioneuroblastoma is an uncommon but curable disease in a high proportion of cases. The treatment is controversial. Radiotherapy, alone or combined with surgery, has demonstrated to be an effective treatment in early stages. Chemotherapy, associated to radiotherapy, can improve the outcome in advanced stages and reduce the morbidity related to surgery. Three cases treated with radiotherapy, and one case treated with chemotherapy followed by radiotherapy are reported. Diagnosis and treatment management are discussed.
