title: [Malignant fibrous histiocytoma of head and neck: clinical analysis of 21 cases].
abstract: OBJECTIVE
  Malignant fibrous histiocytoma (MFH) is a type of pleomorphic neoplastic diseases with complex pathological structure. Its histological origin is uncertain. It was often classified as other carcinoma. This study was designed to investigate the clinical and pathological features and improve the diagnosis and treatment.
  
  
  METHODS
  To summarize and analyze the clinical experiences of 21 cases of MFH at head and neck proved histologically from June 1984 to June 1999 treated in Department of Head and Neck Surgery, Henan Tumor Hospital.
  
  
  RESULTS
  Twenty cases were followed up more than 3 years; one case was lost. The 3-year survival rate was 42.9%(9/21). Nineteen cases were treated with surgery. Two cases in advanced stage were treated by non-surgery who died in 2 and 5 months. Among the patients treated with surgery, 6 cases survived without evidence of recurrence more than 3 years, 13 cases recurred within 2 years and 9 cases with metastasis. Seven cases received second surgery after recurrence. Among them,3 cases survived more than 3 years after second surgery. Of all 21 patients, 12 were proved with cervical lymph node metastasis.
  
  
  CONCLUSIONS
  MFH at head and neck region is a kind of malignant disease with high recurrent rate and the cervical lymph node metastasis rate was 57.1%. Amplified radical surgery is the first choice of treatment. The second surgery has special value to the recurrent patients. Radiotherapy alone or chemotherapy alone is not effective to MFH of head and neck region.
