title: [Therapeutic effect of gamma-ray stereotactic radiotherapy on brain metastases].
abstract: OBJECTIVE
  To evaluate the therapeutic effects of gamma-ray stereotactic radiotherapy (SRT) plus whole brain irradiation and radiotherapy alone in brain metastases.
  
  
  METHODS
  Forty-three patients with brain metastases were treated by SRT plus whole brain irradiation and 50 patients were treated by routine radiotherapy. SRT was given with the dosage of 15-27 Gy, and whole brain irradiation was given with the dosage of 30-40 Gy.
  
  
  RESULTS
  One-year survival rate, median survival period, and tumor local control rate in SRT plus whole brain irradiation group were higher or longer than those in the routine radiotherapy group (P < 0.01). Mortality in SRT plus whole brain irradiation group was lower than that in the routine radiotherapy group (P < 0.05).
  
  
  CONCLUSIONS
  The therapeutic effect of SRT plus whole brain irradiation on brain metastasis of cancer is superior to the routine radiotherapy.
