Abstract
Background
The geographical catchment area served by the Neurosurgical Unit in Aberdeen, Scotland is the largest in the United Kingdom. We examined whether a distance-decay effect on survival exists for patients diagnosed with glioblastoma, who have to travel substantial distances for neurosurgical and oncological treatment in the north of Scotland.
Methods
Electronic medical records of adult patients with glioblastoma, referred for treatment between 2007 and 2018, who underwent surgical resection were reviewed. Travel time by car (as a measure of distance travelled) was calculated from the patients’ home to their general practice (GP) and to their main neuro-oncological centre.
Results
There were 122 patients; 71 (58.2%) were male and the mean age was 57.8 years. The urban-rural split was 61.5% and 38.5%, respectively. Median driving time to the neuro-oncological centre was 36 min and to the GP this was 6 min. Most patients underwent either sub-total (49.6%) or gross total (46.3%) surgical resection. Post-operative treatments included: radiotherapy only (15.6%), chemotherapy only (6.6%), and chemotherapy with radiotherapy (63.1%). Temozolomide was used in 70.5% of patients. Seventeen patients did not receive any post-operative chemo-radiotherapy. The median survival time was 345 days. There was no statistically significant association between distance travelled and survival time in days. MGMT methylation status, extent of resection, Charlson co-morbidity index and treatment received significantly affected survival.
Conclusions
There was no evidence of disadvantage on survival time for patients living further from their neuro-oncological centre compared to those who live nearer.
