“…These cases accounted for 6.0% of all cancers identified in the study: three times higher than expected. 61 Asbestos, vulcanization fumes and, particularly, nitrosamines have been considered as the possible causative agents of cancer in the rubber industry, in addition to naphthylamine. 60 A case-control study from the United States found risk factors of more than 3.0 for railroad industry workers, sheet metal workers, grinding wheel operators and automobile mechanics.…”

The city of São Paulo exhibits one of the highest incidences of laryngeal cancer in world and Brazil presents remarkable occurrence, compared with other Latin American countries. Around 8,000 new cases and 3,000 deaths by laryngeal cancer occur annually in the Brazilian population. In the city of São Paulo, incidence rates for laryngeal cancer among males have been decreasing since the late 1980s while, among females, the rates have shown a stable trend. This phenomenon is probably the expression of changes in gender behavior related to tobacco smoking. Several risk factors are involved in the genesis of laryngeal cancer. The most important are tobacco smoking and alcohol intake, but occupational hazards have also been associated with the disease, such as asbestos, strong inorganic acids, cement dust and free crystalline silica. Additionally, salted meat and total fat intake have been linked to elevated risk of laryngeal cancer. Conversely, several studies have confirmed that fruits, raw leaf vegetables and legumes protect against this cancer. Some researchers have postulated a possible association between laryngeal squamous cell carcinoma and human papilloma virus (HPV), but this is not universally accepted. Gastroesophageal reflux disease is weakly, but consistently correlated with laryngeal cancer. Familial cancer clusters, particularly of head and neck tumors, seem to increase the risk of laryngeal cancer. Some genetic polymorphisms, such as of genes that code for xenobiotic-metabolizing enzymes, have shown elevated risk for laryngeal cancer according to recent studies. Public health policies regarding the control of tobacco smoking and alcohol consumption, and also surveillance of carcinogen exposure in occupational settings, could have an impact on laryngeal cancer. No proposals for screening have been recommended for laryngeal cancer, but one diagnostic goal should be to avoid treatment delay when suspected symptoms have been observed.

“…La variable temporal de la exposición ocupacional a los factores cancerígenos necesita ser considerada para las investigaciones, ya que los trabajadores con mayor tiempo de actuación en el trabajo y, consecuentemente, mayor probabilidad de exposición a sustancias cancerígenas tienen mayor probabilidad de desarrollar cáncer. Los trabajadores que iniciaron la actividad en la industria, por ejemplo, hace más de veinte años presentaron asociación positiva con diferentes muertes por cáncer 15 . Aunque son significativas las características relacionadas con el diagnóstico, en lo que se refiere a la exposición a las radiaciones no ionizantes, las evidencias aún no son conclusivas al respecto.…”

Se estima que entre el 2 y el 4% del cáncer mundial está asociado a la exposición de agentes carcinogénicos en el ambiente laboral. Los objetivos de este estudio fueron describir las características de las notificaciones del cáncer relacionado con el trabajo en Brasil en el periodo de 2007 a 2012 y evaluar la completitud de las variables de estas notificaciones. Estudio de corte transversal de cuño descriptivo a partir de los datos recolectados en el Sistema de Información de Agravios de Notificación. En el período en estudio fueron notificados 269 casos de cáncer relacionado con el trabajo con mayor frecuencia en la región Centro-Oeste (59,1%) de casos de cáncer de piel (92,0%) entre trabajadores de la agropecuaria, forestales y de la caza y pesca (43,5%) que tenían 11 a 20 años de trabajo en la ocupación (24,2%) y eran autónomos (30,1%). Cuanto a la clasificación de campos incompletos se evidenció la minoría de las variables como muy malo en lo llenado. Es necesaria notificaciones con relleno completo y actuación de la vigilancia en salud del trabajador con acciones de prevención contra los cánceres relacionados con el trabajo para reducir esta incidencia y promover la salud del trabajador en ambientes saludables.Palabras-chaves: Epidemiología Descriptiva. Neoplasias. Salud Laboral. Notificación de Enfermedad. AbstractIt is estimated that 2-4% of the world's cancer is associated with exposure to carcinogens in the workplace. The objectives of the study were to describe the characteristics of occupational cancer notifications in Brazil from 2007 to 2012, and to evaluate the completeness of the variables of these notifications. This was a descriptive cross-sectional study from the data collected in the Injury Notification Information System. In the study period 269 cases of occupational cancer were more often reported in the Midwest (59.1%), of cases of skin cancer (92.0%), among workers in agriculture, forestry and hunting and fishing (43.5%), who were 11-20 years of work in profession (24.2%), and were self-employed (30.1%). As for classification of incomplete fields, it was evident that the minority of the variables in the notification were poorly filled out. The complete filling out of notifications and monitoring workers' health with preventative actions against occupational cancers are necessary to reduce their incidence and promote workers' health in healthy environments.

“…Farmers and rubber tappers skin and airways are easily exposed to these agents as solar radiation, pesticides, solvents, fumes and gases containing hydrocarbons and benzene during the work time. There is considerable evidence of accumulation on the carcinogenic action of these chemicals used in agriculture, especially pesticides 14,16 . The International Agency for Research on Cancer (IARC) 12 recognizes sufficient evidence on the carcinogenicity of 18 pesticides and other evidence to 16.…”

“…Organochlorines, chemical products that we can find in pesticides, belong to Group 2B carcinogens by IARC, DDT, dichlorodiphenyltrichloroethane, and are associated with the development of liver cancer, lung and lymphoma in laboratory animals 6 . In the case of solar radiation and rubber industry agents, classified in Group I, there are sufficient evidence of carcinogenicity in human beings 12,16 .

Cancer incidence and mortality in rural workers in the Brazilian Western Amazon

Aim To conduct an exploratory study about cancer incidence and mortality in rural workers in the state of Acre, Brazil. Methods The Proportional Cancer Incidence Ratio (PCIR) was calculated for rural male workers who live in Rio Branco, Acre, with histological diagnosis of cancer, and the Cancer Mortality Odds Ratio (CMOR) comparing cancer deaths occurred in rural workers in the state of Acre with those occurred in people with other occupations in the period from 2007 to 2012. Results High and statistically significant PCIR were observed for tumors of larynx, PCIR = 7.55 (95% CI 4.23-12.46); melanoma, PCIR = 11.44 (95% CI 6.55-18.54); and non – Hodgkin lymphoma, PCIR = 10.00 (95% CI 5.17-17.50) compared to the population of Rio Branco. Regarding the mortality compared analysis, we can observe CMOR = 6.94 (95% CI 1.73-27.89) for pancreatic cancer and CMOR = 13.89 (95% CI 1.25-153.60) for cancer of the urinary tract. Conclusion The results suggest an increase in the incidence estimates of mortality for selected tumor sites among rural workers that are consistent with the literature.
