Survival of patients with glioblastoma multiforme has not improved between 1993 and 2004: analysis of 625 cases.

Glioblastoma is the most common primary brain tumour. The aim of this study was to determine trends in survival over a 12-year period. Survival data were collected retrospectively for 625 patients who had surgery for histologically-confirmed glioblastoma between 1993 and 2004 in a single centre. Data including age, sex, preoperative Karnofsky performance score, tumour site, date of surgery, and type of surgical and adjuvant treatment were collected. Overall median survival was 189 days; there was no significant change in survival over 12 years. Multivariate analysis identified the following independent positive prognostic factors: age <60 years (p < 0.0005), Karnofsky score > or = 70 (p < 0.0001), tumour debulking, rather than biopsy (p < 0.001), right-sided lesion (p < 0.05), unilateral tumour (p < 0.05) and radiotherapy (p < 0.0001). Despite neurosurgical advances, the survival of patients with glioblastoma has not changed for more than a decade. Although, overall, glioblastoma has a short survival, our data show that individual patient survival is heterogeneous.
