Abstract
Malignant glioma (glioblastoma and anaplastic astrocytoma) remain incurable despite extensive resection, radiotherapy, chemotherapy and experimentaltherapies. Few studieshave addressed either the costsofvarious treatmentsfor malignant glioma or their cost effectiveness. The aims of this study were to identify direct hospital costs of treating patients with biopsy proven malignant glioma. The study was carried out within the setting of a dedicated neuro-oncology clinic at a university teaching hospital and included 236 patients treated between 1989 and 1995. The study used the unit costing of each item of treatment according to NHS National Costing Project. The cost of treatment was broken down into its various components: bed days, investigations, surgery, radiotherapy, chemotherapy and neuro-oncology out-patient follow-ups. The mean costs for each of the items based on 1995 figures for the 157 patients having surgery followed by radiotherapy were neuroradiological investigations ( 442), neurosurgical bed days ( 2407), neurosurgery ( 2068), neuropathology ( 434), radiotherapy ( 8832), out-patients( 1078) and chemotherapy ( 440). Totaltreatmentcosts per patient ranged from 1978 to 26980. Median costs of care decreased sequentially with worsening MRC Brain Tumour prognostic group. Management of patients with the best prognosis (MRC index score of 1-10) cost a median of 16550 (range 4572-26,090) whilst the median management cost of those in the worst prognostic group (MRC score 34-38) was 6514(range 1978-18,360). The median costofeach week of survivalin the patients with the bestoutcome (MRC score 1-10) was 150 compared to 232 for each week of survival for patients in the worst prognostic group (MRC score 34-38). This study made no attempt to collect costs of supportive or community-based care. Prospective studies are required to collect such data, as well as assessing the costs effectiveness of alternative treatment strategies.
