Re-analysis of risk for glioma in relation to mobile telephone use: comparison with the results of the Interphone international case-control study.

摘要

The long-awaited Interphone study on use of mobile phones and the risk of brain tumour was recently published. It was coordinated by International Agency for Research on Cancer (IARC) and included 16 research centres from 13 countries. Results for cases aged 30-59 years of age diagnosed during study periods of 2-4 years between 2000 and 2004 were presented. Our research group has published results for brain tumour risk and long term use of mobile phones. In contrast to Interphone, we also included use of cordless phones. Radiofrequency emissions from a cordless phone are in the same magnitude as from a digital mobile phone, as discussed in our publications and recently shown also by Redmaync et al. Moreover, cordless phones are used for longer calls. Including such use in the 'unexposcd' group as in the Interphone study would bias the odds ratio (OR) towards unity. We have previously compared study methods and results in our investigations with those in the Interphone group.
