Abstract

The Hardell-group conducted during 1997-2003 two case-control studies on brain tumours including assessment of use of mobile phones and cordless phones. The questionnaire was answered by 905 (90%) cases with malignant brain tumours, 1,254 (88%) cases with benign tumours and 2,162 (89%) population-based controls. Regarding astrocytoma highest risk was found for ipsilateral mobile phone use in the > 10 year latency group, OR = 3.3, 95% CI = 2.0-5.4, and for cordless phone use OR =5.0, 95% CI = 2.3-11. Also for acoustic neuroma, the highest OR was found for ipsilateral use and > 10 year latency yielding for mobile phone OR = 3.0, 95% CI = 1.4-6.2 and cordless phone OR = 2.3, 95% CI = 0.6-8.8. Overall highest OR for mobile phone use was found in subjects with first use < 20 years age. The annual age adjusted incidence of astrocytoma for the age group >19 years old increased statistically significantly by +2.16%, 95% CI +0.25 to +4.10 during 2000-2007 in Sweden in spite of seemingly underreporting of cases to the Swedish Cancer Registry. The Interphone studies are conducted under the auspice of the International Agency for Research on Cancer (IARC). The study design and epidemiological methods are compared with those in the Hardell group. It is concluded that while the Hardell group results appear to be sound and reliable, several of the Interphone findings display differential misclassification of exposure due to observational and recall bias, for example, following low participation rates in both cases and controls and bed-side computer guided interviews of cases rather than blinded interviews of cases and controls. However, a meta-analysis showed a consistent pattern of an association between mobile phone use and ipsilateral glioma and acoustic neuroma using ? 10 years latency period.
