We recently reported an increased risk of uveal melanoma among mobile phone users. Here, we present the results of a case–control study that assessed the association between mobile phone use and risk of uveal melanoma. We recruited 459 uveal melanoma case patients at the University of Duisburg-Essen and matched 455 case patients with 827 population control subjects, 133 with 180 ophthalmologist control subjects, and 187 with 187 sibling control subjects. We used a questionnaire to assess mobile phone use and estimated odds ratios (ORs) and 95% confidence intervals (95% CIs) of risk for uveal melanoma using conditional logistic regression. Risk of uveal melanoma was not associated with regular mobile phone use (OR = 0.7, 95% CI = 0.5 to 1.0 vs population control subjects; OR = 1.1, 95% CI = 0.6 to 2.3 vs ophthalmologist control subjects; and OR = 1.2, 95% CI = 0.5 to 2.6 vs sibling control subjects), and we observed no trend for cumulative measures of exposure. We did not corroborate our previous results that showed an increased risk of uveal melanoma among regular mobile phone users.
| CONTEXT AND CAVEATS Prior knowledge Although there is no direct link between exposure to radio waves and the genotoxic mechanisms that lead to cancer, studies to address the association between use of cellular telephones and cancer risk have been performed. Study design Case-control study of uveal melanoma patients in Germany using three groups of control subjects: population-based, siblings of patients, and ophthalmology control subjects. Contributions No association between cellular telephone use and uveal melanoma risk was observed. Implications Using cellular telephones is not associated with increased risk of uveal melanoma. Limitations Subjects who agreed to participate in the study were more likely to regularly use cellular telephones than subjects who did not agree to participate. From the Editors
