dc.description.abstractOn 31 May 2011 the WHO International Agency for Research on Cancer IARC categorised radiofrequency electromagnetic fields RF EMFs from mobile phones and from other devices that emit similar non ionising electromagnetic fields as a Group 2B i e a possible human carcinogen A causal association would be strengthened if it could be shown that the use of wireless phones has an impact on the survival of glioma patients We analysed survival of 1678 glioma patients in our 1997 2003 and 2007 2009 case control studies Use of wireless phones in the 20 years latency group time since first use yielded an increased hazard ratio HR 1 7 95 confidence interval CI 1 2 2 3 for glioma For astrocytoma grade IV glioblastoma multiforme n 926 mobile phone use yielded HR 2 0 95 CI 1 4 2 9 and cordless phone use HR 3 4 95 CI 1 04 11 in the same latency category The hazard ratio for astrocytoma grade IV increased statistically significant per year of latency for wireless phones HR 1 020 95 CI 1 007 1 033 but not per 100 h cumulative use HR 1 002 95 CI 0 999 1 005 HR was not statistically significant increased for other types of glioma Due to the relationship with survival the classification of IARC is strengthened and RF EMF should be regarded as human carcinogen requiring urgent revision of current exposure guidelines
