The INTEROCC project is a multi-centre case-control study, aiming to examine occupational exposures to chemical agents and EMF and risk of brain cancer. The FINJEM is considered as the most appropriate job exposure matrix. Modifications were applied to FINJEM resulting in the development of the INTEROCC- FINJEM. The refinements in the INTEROCC FINJEM included the development of a cross-walk between the Finnish occupational code and ISCO-68 codes. Coding/exposure issues were addressed, e.g., supervisors and petrol station attendant increasing benzene exposure estimates pre-1974, and improving diesel and gasoline exhaust fume exposure assessment. Generally, the modifications resulted in an increase in the number of INTEROCC subjects that were considered to be exposed to chemical agents. When assigning subjects to cumulative exposure groups, the cumulative exposure level for the highest exposure group increased for most of the agents.The modifications applied in developing the INTEROCC FINJEM improved the exposure estimates for this international study, based on peer review.
