Abstract Objectives: To study the use of cellular and
cordless telephones and the risk for malignant brain
tumours. Methods: Two case-control studies on malignant
brain tumours diagnosed during 1997-2003 included
answers from 905 (90%) cases and 2,162 (89%)
controls aged 20-80 years. We present pooled analysis
of the results in the two studies. Results: Cumulative
lifetime use for >2,000 h yielded for analogue cellular
phones odds ratio (OR)=5.9, 95% confidence interval
(CI)=2.5-14, digital cellular phones OR=3.7, 95%
CI=1.7-7.7, and for cordless phones OR=2.3, 95%
CI=1.5-3.6. Ipsilateral exposure increased the risk for
malignant brain tumours; analogue OR=2.1, 95%
CI=1.5-2.9, digital OR=1.8, 95% CI=1.4-2.4, and
cordless OR=1.7, 95% CI=1.3-2.2. For high-grade
astrocytoma using >10 year latency period analogue
phones yielded OR=2.7, 95% CI=1.8-4.2, digital
phones OR=3.8, 95% CI=1.8-8.1, and cordless phones
OR=2.2, 95% CI=1.3-3.9. In the multivariate analysis
all phone types increased the risk. Regarding digital
phones OR=3.7, 95% CI=1.5-9.1 and cordless phones
OR=2.1, 95% CI=0.97-4.6 were calculated for malignant
brain tumours for subjects with first use <20 years
of age, higher than in older persons. Conclusion: Increased
risk was obtained for both cellular and cordless
phones, highest in the group with >10 years latency
period.
