title: Management of hemangiopericytomas in the central nervous system.
abstract: OBJECTIVE
  To elucidate the clinical features and treatment of Hemangiopericytomas (HPCs) in the central nervous system.
  
  
  METHODS
  Twenty-six HPC operations performed at Huashan Hospital from January 1993 to June 1999 were analyzed retrospectively, and a review of relevant literatures was done.
  
  
  RESULTS
  Among the 26 cases, total tumor removal was achieved in 24 cases, and subtotal removal in 2 cases. Postoperatively, neurological symptoms were improved or unchanged in 21 cases, worsened in 4 cases, and pneumonia caused death in 1 case. Eighteen patients received postoperative radiotherapy. Eighteen patients were followed up from 1 month to 58 months (average, 22 months). During the follow-up period, 2 patients presented one or more distant metastasis, and one patient died of recurrence.
  
  
  CONCLUSIONS
  Surgical management is the best choice for treatment of patients with HPCs. Postoperative radiotherapy can postpone the risk of tumor recurrence.
