Abstract

Background: We analysed the survival of patients after glioma diagnosis in relation to the use of wireless phones. Methods: All cases diagnosed between 1997 and 2003 with a malignant brain tumour (n = 1,251) in our case-control studies were included and followed from the date of diagnosis to the date of death or until May 30, 2012. Results: For glioma, the use of wireless phones (mobile and cordless phones) gave a hazard ratio (HR) = 1.1 (95% confidence interval, CI = 0.9–1.2), with >10-year latency HR = 1.2 (95% CI = 1.002–1.5, p trend = 0.02). For astrocytoma grade I-II (low-grade), the results were, HR = 0.5 (95% CI = 0.3–0.9) and for astrocytoma grade IV (glioblastoma), HR = 1.1 (95% CI = 0.95–1.4), with >10 year latency HR = 1.3 (95% CI = 1.03–1.7). In the highest tertile (>426 h) of cumulative use, HR = 1.2 (95% CI = 0.95–1.5) was found for glioblastoma. The results were similar for mobile and cordless phones. Conclusions: Decreased survival of glioma cases with long-term and high cumulative use of wireless phones was found. A survival disadvantage for astrocytoma grade IV, but a survival benefit for astrocytoma grade I-II was observed which could be due to exposure-related tumour symptoms leading to earlier diagnosis and surgery in that patient group.
