title: [Analysis of diagnosis and treatment of 6 cases with esthesioneuroblastoma].
abstract: OBJECTIVE
  To explore the diagnosis and treatment and prognosis of esthesioneuroblastoma.
  
  
  METHODS
  The clinical data of 6 cases with esthesioneuroblastoma were analyzed retrospectively. One case was treated with radiotherapy alone; Four cases were treated with surgery combined with radiotherapy; One case was treated with surgery combined with radiotherapy and chemotherapy.
  
  
  RESULTS
  All cases have been followed up for one to ten years and the 1-year, 3-year and 5-year survival rate were 100.0% (6/6), 83.3% (5/6) and 66.7% (4/6) respectively. One case has survived without tumor for 8 years.
  
  
  CONCLUSIONS
  It was the best way to control local recurrence combined with radical surgery and postoperative radiotherapy, and chemotherapy contributed to the prevention of distance metastasis. The key to improving the survival rate of the disease is early accurate diagnosis and combined treatment.
