Riscos ocupacionais para o câncer de laringe: um estudo caso-controle Occupational risks for laryngeal cancer: a case-control study
No full textO tabagismo e o consumo de álcool são os fatores de risco mais bem estabelecidos para o câncer de laringe. Com relação aos fatores ocupacionais, o único carcinógeno estabelecido é a exposição a névoas de ácidos inorgânicos fortes. Entretanto, asbesto, pesticidas, tintas, gases de combustão de gasolina e diesel e poeiras, entre outros, aparecem na literatura como agentes ocupacionais que aumentam o risco de câncer de laringe. Um estudo caso-controle de base hospitalar foi conduzido para investigar fatores de risco ocupacionais para câncer de laringe. Foram coletadas informações detalhadas sobre tabagismo, consumo de álcool e história ocupacional de 122 casos de câncer de laringe e 187 controles pareados por freqüência (segundo sexo e idade). Encontrou-se risco aumentado de câncer de laringe nos indivíduos com exposição à sílica cristalina livre respirável (OR = 1,83; IC95%: 1,00-3,36), à fuligem (de carvão mineral, coque, madeira, óleo combustível) (OR = 1,78; IC95%: 1,03-3,03), a fumos em geral (OR = 2,55; IC95%: 1,14-5,67) e a animais vivos (OR = 1,80; IC95%: 1,02-3,19).The most solidly established risk factors for laryngeal cancer are tobacco and alcohol. As for occupational factors, the only established carcinogen is exposure to strong inorganic acid mists. However, asbestos, pesticides, paints, gasoline, diesel engine emissions, dusts, and other factors have been reported in the literature as occupational agents that increase the risk of laryngeal cancer. A hospital-based case-control study was conducted to investigate occupational risk factors for laryngeal cancer. Detailed data on smoking, alcohol consumption, and occupational history were collected for 122 laryngeal cancers and 187 controls matched by frequency (according to sex and age). Laryngeal cancer was associated with exposure to respirable free crystalline silica (OR = 1.83; 95%CI: 1.00-3.36), soot (from coal, coke, fuel oil, or wood) (odds ratio - OR = 1.78; 95% confidence interval - 95%CI: 1.03-3.03), fumes (OR = 2.55; 95%CI: 1.14-5.67), and live animals (OR = 1.80; 95%CI: 1.02-3.19)

How much do smoking and alcohol consumption explain socioeconomic inequalities in head and neck cancer risk?
No full textBackground A higher burden of head and neck cancer has been reported to affect deprived populations. This study assessed the association between socioeconomic status and head and neck cancer, aiming to explore how this association is related to differences of tobacco and alcohol consumption across socioeconomic strata. Methods We conducted a case-control study in Sao Paulo, Brazil (1998-2006), including 1017 incident cases of oral, pharyngeal and laryngeal cancer, and 951 sex- and age-matched controls. Education and occupation were distal determinants in the hierarchical approach; cumulative exposure to tobacco and alcohol were proximal risk factors. Outcomes of the hierarchical model were compared with fully adjusted ORs. Results Individuals with lower education (OR 2.27; 95% CI 1.61 to 3.19) and those performing manual labour (OR 1.55; 95% CI 1.26 to 1.92) had a higher risk of disease. However, 54% of the association with lower education and 45% of the association with manual labour were explained by proximal lifestyle exposures, and socioeconomic status remained significantly associated with disease when adjusted for smoking and alcohol consumption. Conclusions Socioeconomic differences in head and neck cancer are partially attributable to the distribution of tobacco smoking and alcohol consumption across socioeconomic strata. Additional mediating factors may explain the remaining variation of socioeconomic status on head and neck cancer.European Commission[IC18-CT97-0222]Ludwig Institute for Research on CancerFAPESP (Fundacao de Amparo a Pesquisa no Estado de Sao Paulo)[01/01768-2]FAPESP (Fundacao de Amparo a Pesquisa no Estado de Sao Paulo)[01/12897-8]FAPESP (Fundacao de Amparo a Pesquisa no Estado de Sao Paulo)[04/12054-9
Drinking of maté and the risk of cancers of the upper aerodigestive tract in Latin America: A case-control study
No full textCancers of the upper aerodigestive tract (UADT: oral cavity, oropharynx, hypopharynx, larynx, esophagus) have high incidence rates all over the world and they are especially frequent in some parts of Latin America. In this study, we have evaluated the role of the consumption of maté, a hot herb-based beverage, based on 1168 UADT squamous-cell carcinoma cases and 1,026 frequency-matched controls enrolled from four centers in Brazil and Argentina. The effect of maté drinking on the risk of head-and-neck cancers was borderline significant. A significant effect was observed only for cancer of the esophagus (OR 3.81 (95% CI 1.75-8.30)). While duration of maté drinking was associated with the risk of all UADT cancers, the association with cumulative maté consumption was restricted to esophageal cancer (p-value of linear trend 0.006). The analyses of temperature at which maté was drunk were not conclusive. The increased risk associated with maté drinking was more evident in never-smokers and never-alcohol drinkers than in other individuals. Our study strengthens the evidence of an association between maté drinking and esophageal cancer; the hypothesis of an association with other UADT cancers remains to be clarified. © 2010 Springer Science+Business Media B.V

Remarks: A. ferreirai from the Upper Carboniferous (Piedra Shotle Formation, Chubut) of Argentina, was originally attributed to the palaeodictyopterans but clearly exhibits characters typical for Taiophlebia, and can be therefore transferred to the latter genus.Published as part of Martins-Neto, R.
