Nervous System Cancer

ObjectiveThis study evaluated the relationship between brain and other central nervous system cancer (‘CNS cancer’) and exposures at two semiconductor and electronic module manufacturing facilities and at a storage device manufacturing facility.MethodsThe case–control study, nested in a cohort of 126 836 employees, compared 120 CNS cancer cases and 1028 matched controls with respect to employment in 10 process groups and estimated cumulative exposure to 31 known or possible carcinogens.ResultsCNS cancer was associated with module manufacturing operations at two facilities. Module manufacturing is a process that begins with production of ceramic substrates followed by attachment of completed semiconductor chips and metal-containing circuitry resulting in a high performing electronic device. Positive associations with the highest tertile of estimated cumulative exposure were found for several chemicals, including 2-butoxyethanol, cyclohexanone, ortho-dichlorobenzene, cadmium, molybdenum, trichloroethylene and vinyl chloride.ConclusionsResults suggested positive associations between CNS cancer and specific operations and chemicals experienced in the semiconductor and electronic module manufacturing industry. However, lack of external support for these findings precludes a causal interpretation, and the observed associations may have been due to chance.

Background: Little is known about the relationship between diet and central nervous system (CNS) tumors, especially in terms of their histological subtypes. This study investigated the overall associations between food groups, alcohol intake and CNS tumors, and in particular about the associations between neuroepithelial tumors and meningiomas. Methods: Data were collected through the CERENAT (CEREbral tumors: a NATional study) case-control study conducted in France during the period 2004-2010. Data were available for 1,479 subjects (494 cases, including 201 neuroepithelial tumors, 193 meningiomas, 100 other CNS tumors, and their 985 matched controls). Conditional logistic regressions for matched sets were adjusted based on the participants' educational level, occupation, smoking status and frequency of food group consumption. Results: A heavy consumption of grilled meat and poultry was associated with neuroepithelial tumors in a dose-related relationship (ORQ4vsQ1 = 3.72, 95% CI 1.62-8.52, p = 0.005). Higher fruit and vegetable intake was inversely associated with meningiomas (for fruits: ORQ4vsQ1 = 0.38, 95% CI 0.17-0.87, p = 0.06, for vegetables ORQ4vsQ1 = 0.26, 95% CI 0.11-0.62, p = 0.007). Consumption of alcohol on a daily basis was inversely associated with CNS tumors especially for meningiomas (ORQ4vsQ1 = 0.33, 95% CI 0.18-0.61, p = 0.001). Conclusions: Results obtained in terms of grilled meat, fruits and vegetables consumption were in line with those published in epidemiological literature. Contradictions in results between neuroepithelial tumors and meningiomas confirmed the need to analyze the effects of dietary factors on the basis of the histological subtypes of CNS tumors.
