title: [Clinical analysis of imflammatory myofibroblastic tumor of the nasal cavity and paranasal sinus].
abstract: OBJECTIVE
  To investigate the clinical features, therapeutic methods and therapeutic efficacy of imflammatory myofibroblastic tumor(IMT)of the nasal cavity and paranasal sinuses.
  
  
  METHODS
  Clinical data of 14 cases diagnosed as IMT by pathology were retrospectively analyzed. There were 8 males and 6 females,age ranging from 18 to 77 years. 12 cases of them were treated by surgery while 2 cases received postoperative radiotherapy.
  
  
  RESULTS
  All cases were operated. All the patients were followed up for a period of 1 to 7 years after operation and two cases were proved low grade IMT pathologically. Eight cases survived with no recurrence until the last follow-up and 6 cases relapsed, of which 4 cases died and 2 were alive with tumor.
  
  
  CONCLUSIONS
  IMT of the nasal cavity and paranasal sinuses is very rare. The diagonosis of IMT is based on pathology and immunohistochemistry. Proper diagnosis is essential to avoid mutilating and disfiguring surgical procedures. Radical excision is still the first choice of treatment for IMT of the nasal cavity and paranasal sinuses. Chemotherapy and radiotherapy may not be helpful to prevent recurrence after operation. Due to high recurrence rate, long-term follow up is necessary after operation.
