I ~ 84 - pleura and peritoneum. 2. To ascertain trends in the incidence rates, ) 3. To discover the groups of, the population apparently associated with the tumours end to estimate the incidence in the occupationally and nonoccupatlonaily exposed population as well as the occurrence among those apparently non-exposed (non classified as idiopathic). 4. To establish the dose/effect relationships. To set up a simple mesothelioma register it is first of all necessary to have unbiased details f>om death certificates from all parts of the country. These can be obtained from a central or regional register if these are in existence. Keglstratlon of mesothelioma costs con be peifcimcti at different levels: 1) Crude data can be collected from the death cert;fi cotes of people who died from pleural tumours (international cc !c JC3 and ?i?.4). Details taken from the death certificate could include identificaticr. of the individual: sex: age; place of normal residence; and if possible details of past occupa tion, including asbestos exposure. This source does not provide a reli able diagnosis but is available in the EEC countries, while the unreliability of the diagnosis can be pre: red to be of the sene magnitude in dif ferent areas, at least wit!.in each country. These data can provide information concerning - regional differences - temporal differences - unexpected areas of present or past exposure. 2) well established diagnosis of ell primary tumours of the serosal cavities by histological exartination. Autopsy material is preferable. On a nationwide basis, registration based on these data requires the interest of pathologists in this prot.em. A national mesothelioma panel of 3-5 pathologists is necessary for verifi cation of the diagnosis. As mentioned shove an EEC j:ancl based upon al ready existing national panels has bc-.n formed (Annex 1).
