title: [Prostate sarcoma: a report of 14 cases].
abstract: OBJECTIVE
  To discuss the diagnosis and effective treatment of prostate sarcoma.
  
  
  METHODS
  We analysed the clinical materials of fourteen patients with prostate sarcoma treated in our hospital from Jan. 1991 to Jun. 2004.
  
  
  RESULTS
  Prostate sarcoma accounted for 3.21% of all the prostatic malignant tumors treated in our hospital during that period. The average age was 39.5 years old (ranging from 17 to 62). Twelve cases came to our hospital because of dysuria. Large soft prostate tumors were found in all the patients in physical examination. The serum AKP, ACP and PSA levels were normal in all the 10 patients who had received the test. Pathological test revealed: 7 cases leiomyosarcoma, 1 case rhabdomyosarcoma, 4 cases fibrosarcoma, 2 cases spindle cell sarcoma. Different kinds of prostate sarcoma each his its own immuno-histochemical staining features. Two cases were at Ghavimi Stage I, 5 at Stage II, 3 at Stage III, and 4 at Stage IV. All the patients received surgery, chemotherapy and/or radiotherapy. One case failed to be followed up, 11 died 2 approximately 12 months after diagnosis. Two patients are still alive, 1 for 18 months without recurrence, and the other for through with relapse.
  
  
  CONCLUSIONS
  Dysuria is always the first symptom of prostate sarcoma. DRE test may suggest prostate sarcoma but needle biopsy contributes to a definite diagnosis. The immuno-histochemical dyeing helps to differentiate the disease. The prognosis of prostate sarcoma is very poor and the main treatment is surgery followed by chemotherapy and/or radiotherapy.
