title: Clinical outcome of postoperative radiotherapy with or without chemotherapy in adult glioblastoma multiforme in Ramathibodi Hospital: a retrospective study.
abstract: OBJECTIVE
  To identify the treatment outcome of glioblastoma multiforme (GBM) in Ramathibodi Hospital from overall survival rate and related prognostic factors.
  
  
  METHODS
  Medical records of patients with histological diagnosis of GBM treated at Radiation Oncology Division, Radiology Department, Ramathibodi Hospital between 2000 and 2010 were reviewed and available data extracted for evaluation of treatment outcome.
  
  
  RESULTS
  There were 47 patients with mean age at diagnosis of 51.9 years (range from 18 to 82 years). Surgery (partial 76.6%, total 12.8%, and biopsy 10.6%) followed by postoperative radiotherapy (mean dose 52 gray) was the treatment of choice with or without concurrent and adjuvant Temozolomide (TMZ). With median follow-up time of 0.9 years, the median survival of the patients was 2.1 years (95% CI 1.08-7.36), whereas one and two-year overall survival rates were 78.0% and 57.8%, respectively. In univariate analysis, persistent neurological deficit after surgery and presenting symptom of visual disturbance were identified to lower overall survival while multivariate analysis, younger age, and higher radiation dose were identified as favorable prognostic factors to improve overall survival. Re-surgery or re-irradiation in some selected cases of recurrent or progressive disease was considered as a choice for palliative treatment.
  
  
  CONCLUSIONS
  Proper management of GBM patient was surgical removal and postoperative radiotherapy with or without chemotherapy. Proper palliative treatment modality was considered in selected cases of recurrent or progressive disease.
