Risico op kwaadaardige hersentumor neemt toe door gebruik draadloze/mobiele telefoons Op basis van diagnose gesteld tussen 2000 en 2003: - na meer dan tien jaar analoge mobiele telefoon 3,5 maal meer kans op kwaadaardige hersentumor, - na meer dan tien jaar digitale mobiele telefoon 3,6 maal meer kans op kwaadaardige hersentumor, - na meer dan tien jaar draadloze telefoon 2,9 maal meer kans op kwaadaardige hersentumor. Ook de kans op goedaardige kanker neemt toe. Bronnen: (1). Kwaadaardige hersentumoren. Case-control study of the association between the use of cellular and cordless telephones and malignant brain tumors diagnosed during 2000-2003. Hardell L, Carlberg M, Hansson Mild K. Department of Oncology, University Hospital, SE-701 85 Orebro, Sweden; Department of Natural Sciences, Orebro University, SE-701 82 Orebro, Sweden. Gepuliceerd in: Environ Res. 2005 Jul 12; www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=16023098&query_hl=1 Abstract We performed a case-control study on the use of cellular and cordless telephones and the risk for brain tumors diagnosed during 2000-2003. We report the results for malignant brain tumors with data from 317 cases (88%) and 692 controls (84%). The use of analog cellular phones yielded odds ratio (OR) of 2.6 and a 95% confidence interval (CI) of 1.5-4.3, increasing to OR=3.5 and 95% CI=2.0-6.4 with a >10-year latency period. Regarding digital cellular telephones, the corresponding results were OR=1.9, 95% CI=1.3-2.7 and OR=3.6, 95% CI=1.7-7.5, respectively. Cordless telephones yielded OR=2.1, 95% CI=1.4-3.0, and with a >10-year latency period, OR=2.9, 95% CI=1.6-5.2. The OR increased with the cumulative number of hours of use and was highest for high-grade astrocytoma. A somewhat increased risk was also found for low-grade astrocytoma and other types of malignant brain tumors, although not significantly so. In multivariate analysis, all three phone types studied showed an increased risk. (2). Goedaardige hersentumoren. Case-Control Study on Cellular and Cordless Telephones and the Risk for Acoustic Neuroma or Meningioma in Patients Diagnosed 2000-2003. Hardell L, Carlberg M, Hansson Mild K. Department of Oncology, University Hospital, and Department of Natural Sciences, Orebro University, Orebro, Sweden. Gepubliceerd in: Neuroepidemiology. 2005 Jun 13;25(3):120-128 www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=15956809&query_hl=1 Abstract We performed a case-control study on the use of cellular and cordless telephones and the risk for brain tumors. We report the results for benign brain tumors with data from 413 cases (89% response rate), 305 with meningioma, 84 with acoustic neuroma, 24 with other types and 692 controls (84% response rate). For meningioma, analogue phones yielded odds ratio (OR) = 1.7, 95% confidence interval (CI) = 0.97-3.0, increasing to OR = 2.1, 95% CI = 1.1-4.3 with a >10-year latency period. Also digital cellular phones and cordless phones increased the risk to some extent. For acoustic neuroma, analogue phones gave OR = 4.2, 95% CI = 1.8-10 increasing to OR = 8.4, 95% CI = 1.6-45 with a >15-year latency period, but based on low numbers. Digital phones yielded OR = 2.0, 95% CI = 1.05-3.8, whereas for cordless phones OR was not significantly increased. In the multivariate analysis, analogue phones represented a significant risk factor for acoustic neuroma.
