Survival of glioma patients in relation to mobile phone use in Denmark, Finland and Sweden

Abstract : Gliomas are the most common cancer of the brain. We investigated whether pre-diagnostic mobile phone use was associated with survival. Glioma cases (n=806) in the INTERPHONE study in Denmark, Finland and Sweden were followed up for survival via registry linkages. Cox regression models were used to calculate hazard ratios and 95% confidence intervals. No reduced survival among glioblastoma patients was observed for various measures of mobile phone use relative to no or non-regular use. All significant associations suggested better survival for mobile phone users. Results were similar for high–grade and low–grade gliomas. In conclusion we found no evidence of reduced survival among glioma patients in relation to previous mobile phone use.
