title: [Clinical analysis of 10 cases of olfactory neuroblastoma].
abstract: To review the diagnosis, treatment and prognosis of olfactory neuroblastoma.
  
  
  
  Clinical data were retrospectively reviewed in 10 cases of olfactory neuroblastoma admitted from 1998 to 2002, including data of transmission electron microscopic (TEM) observation in 4 cases. According to Kadish's classification, 2 cases were in stage A, 4 in stage B and 4 in stage C. Three patients were treated with surgery alone, 7 with combined surgery and radiation.
  
  
  
  Among 10 cases, the overall 5-year survival rate was 60 %(6/10); 3 patients died from local recurrence, 1 lost follow-up. TEM demonstrated granules in the cytoplasm of 3 patients.
  
  
  
  The combined surgery and radiation can achieve excellent local control. Transmission electron microscope is important for its diagnosis.
