title: [The experience of treatment of 7 cases of olfactory neuroblastoma].
abstract: OBJECTIVE
  To improve the treatment result of olfactory neuroblastoma.
  
  
  METHODS
  Introduce the experience of treatment of 7 patients with this disease. Among these 7 cases, 2 of them were stage B while the others were stage C according to the system proposed by Kadish. 3 cases received radiotherapy alone, and 4 others received radiotherapy pre-operation. The radiation dose was 5000-7000 cGy. All the patients were followed-up until December 1997.
  
  
  RESULTS
  5 cases are still alive, survival time are 20, 22, 23, 29 and 76 months respectively. The other 2 patients died with the survival time of 6 and 48 months respectively.
  
  
  CONCLUSIONS
  Radiotherapy seems effective in the treatment of olfactory neuroblastoma; the combination of chemo-radio-therapy is preferable for advanced or metastasis olfactory neuroblastoma. We extrapolate there are different subtypes on pathology in this tumor.
