To date, there is a remarkable discrepancy between the number of identified occupational-related bladder cancer cases reported to the authorities and the numbers estimated by renown experts. Doll and Peto (1981) estimated the portion of bladder cancer cases related to occupation in the United States at 10% in men and 5% in women. In 2010, Rushton et al. estimated that for men the occupational attribution factor for bladder cancer in Britain is 7.1%. In emerging nations or less developed countries suitable approaches to identify occupational bladder cancer cases are less or even not known. Therefore, within the project Bladder Cancer Documentation of Causes: multilingual questionnaire “Bladder Cancer Doc” of the World Health Organisation Collaborating Centres in Occupational Health, a questionnaire developed by the Dortmund group and applied in hospital-based bladder cancer studies in Germany as well as in after-care bladder cancer patients, was translated into more than 30 languages (Afrikaans, Arabic, Bengali, Chinese, Czech, Dutch, English, Finnish, French, Georgian, German, Greek, Hindi, Hungarian, Italian, Indonesian, Japanese, Canada, Kazakh, Kirghiz, Korean, Latvian, Malay, Persian (Farsi), Polish, Portuguese, Portuguese/Brazilian, Romanian, Russian, Serbo-Croatian, Slovak, Spanish, Spanish/Mexican, Tamil, Telugu, Thai, Turkish, Urdu, Vietnamese) (Golka et al., 2012).

The bipartite questionnaire asks for relevant medical information in the physician‘s part like histopathological classification of the tumour, applied therapy, relapses etc. and for the occupational history regarding all jobs or occupations held for more than 6 months since leaving school in the patient‘s part. For selected approved or suspected occupational and non-occupational bladder cancer risk factors this questionnaire is additionally asking for intensity and frequency. Furthermore, the literature regarding occupations like painter, hairdresser or miner and exposures like carcinogenic aromatic amines, azo dyes, or combustion products is highlighted.
