Here we present progress on an update of a British cohort of rubber industry workers and for an international pooled cohort study coordinated by the International Agency for Research on Cancer.
The UK cohort consists of 40,867 men aged 35+ who were employed in the British rubber industry on 1 February 1967. The previous analysis found an excess of bladder cancer mortality where exposure to antioxidants may have occurred. An excess of lung cancer was observed in the total industry. We have received research governance clearances from ethics, Health Research Authority Confidentiality Advisory Group, Office for National Statistics’ Microdata Release Panel, the Health and Social Care Information Centre (HSCIC) Data Access Advisory Group for England and Wales and Public Benefit and Privacy Panel for Scotland for mortality and cancer incidence follow-up. The cohort is currently being traced for mortality by HSCIC and we plan to present preliminary results at the meeting in June.
Preliminary results will be presented on trend analyses for UK-exposure information from the EXASRUB database, which will develop exposure models specifically for the British industry. Sensitivity analyses to investigate the assumptions made as part of the exposure assessment will also be carried out.
The international pooled study anticipates pooling data from Great Britain, Poland, Germany, Holland and Sweden, making this not only the largest ever evaluation of cancer risks in the rubber industry, but also the first large investigation using quantitative exposure assessments for a number of potential carcinogens pertinent to this industry. We will report on progress with the international pooled study.
