To determine the effect of waiting time for radiotherapy on the overall survival of patients with high-grade gliomas.


We examined records of patients with grade III/IV gliomas who were referred to radiotherapy after surgery or biopsy - ECOG <3, any age, radical intent or palliative intent with dose >50 Gy, no interstitial or radiosurgery boost. Waiting time was defined in two ways, time from biopsy to radiotherapy and time from presentation to radiotherapy department to start of radiotherapy.


There were 182 patients in the study having a median survival of 8.5 months, with a median follow up of 10.5 months. The group comprised of 63 (35%) grade III and 119 (65%) grade IV gliomas. Median times and ranges from biopsy and presentation to treatment were 26 days (4-78 days) and 15 days (1-62 days), respectively. The median dose was 60 Gy in a median of 30 fractions over a median of 46 days. Tumour progression before and during radiotherapy occurred in seven patients (4%) and 19 patients (11%), respectively. One hundred and seventy-nine patients died of disease. The seven patients whose tumour progressed before radiotherapy were excluded from the analysis of prognostic variables. In a multivariate analysis the variables that were significantly associated with worse survival were older age, reduced dose and prolonged waiting time from presentation. The risk of death increased by 2% for each day of waiting for radiotherapy.


The study showed longer waiting time from presentation at radiotherapy department to treatment to be a significant predictor of overall survival for patients with high-grade glioma.
