| All cases of pleural malignant mesothelioma occurring in Tuscany were
collected, backdated to 1980 (to 1970 for the
provinces of Florence and Prato; to 1975 for the provinces of Pisa
and Siena), in order to evaluate the incidence of
occupational exposure to asbestos. The aim was to enhance primary
prevention in those workplaces still at risk nowadays. To
achieve information on the possible occupational, domestic or
environmental exposure, an interview was conducted using a
semi-structured questionnaire. An exposure classification was
produced to focus preventive intervention. This surveillance
system needs to be developed to contribute to epidemiological
research, especially on the effects of low level exposures, and to
primary prevention.

| Following the finding of an unexpected cluster of mesotheliomas in
textile workers, a surveillance system of malignant
mesotheliomas was implemented in the region of Tuscany, Italy. This
article reports on the investigation of 124 cases of
mesothelioma diagnosed and reviewed by the Institutes of Morbid
Anatomy and Histopathology at the Universities of Florence,
Pisa, and Siena between 1970 and 1988. A complete occupational and
asbestos exposure history was assessed through a
semi-structured questionnaire directly administered to resident cases
of Tuscany or, if deceased, to their closest living relatives,
for a total of 100 interviews. The hypothesis of past occupational
asbestos exposure was verified and documented.
Seventy-two cases have been classified as occupationally exposed to
asbestos; four were classified in the category of possible
domestic exposure to asbestos. For two others, the role of other

| A case-control study on pleural malignant mesothelioma (MM) was
conducted in Casale Monferrato, where the largest Italian
asbestos cement (AC) factory had been operating from 1907 to 1985. In
a previous study we observed a five to seven-fold
increase in the incidence of MM among people living in that city and
never employed in the factory mentioned. The present
study includes cases of MM with histological diagnosis over the
period 1.1.1987-30.6.1993 among residents in the Local
Health Unit (LHU) of Casale Monferrato. Population controls were
randomly extracted from the list of the residents in the
LHU, matched to cases on , date of birth, vital status and date of
death. Cases and controls (or their closest relative) were
interviewed with a standardised questionnaire focusing on asbestos
exposure in the (life-long) residential and occupational
histories and in leisure time activities as well as on occupational

| A collaborative study has been performed in order to detect cases of
pleural mesothelioma diagnosed or treated in Italy in the
years 1984-88. Cases have been notified to ISS by 88 centres (clinics
of thoracic surgery and respiratory diseases, oncologic
centres, institutes of pathology), active in 14 Italian regions.
Altogether, 575 cases (415 males and 160 females) have been
included in the study. Information on occupation and/or on non
occupational exposure to asbestos was available for 65% of the
subjects, and the occurrence of definite or possible exposure to
asbestos was estimated for 58% of them.

| The analysis of 335 cases of mesothelioma observed at the Ramazzini
Foundation and the Bologna Institute of Oncology has
shown: 1) a high percentage of correlation of these tumours with
asbestos exposure; 2) a large number of population categories
potentially exposed to asbestos fibres and therefore at risk of
developing mesothelioma; and 3) the high risk of mesothelioma
among people exposed in various circumstances to asbestos used in
railroads and sugar refinery plants.
