OBJECTIVE: A study called OCCAM (OCcupational CAncer Monitoring) has been carried out in order to establish a nationwide surveillance system for occupational cancer. This project consists of population-based case control studies where information on past occupations are automatically gathered National Institute for Social Security's archive, cancer cases are obtained from Cancer Registries (CR) and controls are sampled from population files of the National Health Service. As previous results obtained using CR were encouraging, we tried to use regional hospital discharge records as a source of incident cases. DESIGN: We have conducted a population based case-control study with 1568 male bladder cancer cases occurred in the years 1999 and 2000 and 18818 controls randomly sampled from resident population in Lombardy region (Italy). RESULTS: Despite the limits of this approach the following industries were found at increased risk of bladder cancer: leather and shoes industry (OR=1.83; CI 90%: 1.01-3.33; observed: 10); transports (OR=1.28; CI 90%: 0.94-1.76; observed: 37), rubber industry (OR=1.22 CI 90% 0.80-1.85; observed: 19) and printing industry (OR=1.5 CI 90%: 1.10-2.05; observed: 38). CONCLUSION: The ability of OCCAM surveillance system to find known associations using routinely available data offers new opportunities to detect cancer cases likely to be of occupational origin.
