                                  Abstract

                                  Background: Lung cancer incidence in Central and Eastern Europe (CEE) is among the highest in the world, and the role of occupational exposures has not been adequately studied in these countries.

                                  Objectives: To investigate the contribution of occupational exposure to polycyclic aromatic hydrocarbons (PAH) to lung cancer in CEE.

                                  Methods: A case-control study was conducted in Czech Republic, Hungary, Poland, Romania, Russia, and Slovakia, as well as the United Kingdom (UK) between 1998 and 2002. Occupational and socio-demographic information was collected through interviews from 2861 newly diagnosed lung cancer cases and 2936 population or hospital controls. Industrial hygiene experts in each country evaluated exposure to 70 occupational agents, whereof 15 mixtures containing PAH. Odds ratios (OR) of lung cancer were calculated after adjusting for other occupational exposures and tobacco smoking.

                                  Results: The OR for ever-exposure to PAH in the CEE countries was 0.93 (95% CI 0.77-1.14). The OR for the highest category of cumulative exposure, duration of exposure and intensity of exposure were 1.13 (95% CI 0.80-1.58), 1.02 (95% CI 0.66-1.57) and 1.11 (95% CI 0.60-2.05), respectively. The OR for ever PAH exposure in the UK was 1.97 (95% CI 1.16-3.35).

                                  Conclusion: Occupational PAH exposure does not appear to substantially contribute to the burden of lung cancer in CEE. The apparently stronger effect observed in the UK may be due to high exposure levels and a joint effect with asbestos.
