[Tuscany mesothelioma registry (1988-2000): evaluation of asbestos exposure].

BACKGROUND: The Tuscany Mesothelioma Register (ARTMM) records pleural malignant mesothelioma cases of Tuscany residents, diagnosed by histological, cytological, or clinical (radiography or computerized tomography) examinations. The ARTMM began in 1988 and estimates mesothelioma incidence in Tuscany and collects information on past asbestos exposure of mesothelioma cases. OBJECTIVES: The aim of this paper was to describe the incidence of pleural mesothelioma cases in Tuscany and to analyse their possible past asbestos exposures. METHODS: We considered pleural mesothelioma cases recorded in ARTMM in the period 1988-2000 and interviews collected for these cases. In order to identify past asbestos exposure in the occupational and non-occupational history of patients, interviews were carried out using a standardised questionnaire. RESULTS: In the period 1988-2000, 494 pleural malignant mesothelioma cases were recorded in the ARTMM; 82% were males. In the periods 1988-1993, 1994-1997, 1998-2000 the incidence rates, standardised on the Italian population (per 100,000), were respectively 1.15, 1.57, 2.58 among males; 0.29; 0.27; 0.29 among females. Information on occupational history was collected for 418 mesothelioma patients (85% of recorded cases): 173 mesothelioma cases were directly interviewed; for 245 cases relatives or work colleagues were interviewed. Occupational asbestos exposure was ranked as certain, probable or possible in 72% of the interviewed cases (80% of males; 20% of females). Environmental and non-occupational asbestos exposure was identified in 1% of males, and 3% of females. In 24% of the interviewed cases (15% of males; 74% of females) no known asbestos exposure was identified. Occupational asbestos exposure occurred in maritime activities (shipyards, dock work, merchant and regular Navy), the building industry, railway carriage construction and maintenance, rail transport, textile industries (mainly rag sorting), electricity production, asbestos cement manufacture, chemical, iron and steel industries and in glass manufacturing. In Tuscany two areas are distinguished for their well-documented and massive use of asbestos: the coastal areas (Livorno and Massa Carrara) for maritime activities, and the areas of Pistoia and Arezzo for railway carriage construction and repair. Mesothelioma incidence rates in these areas are the highest in the whole region. CONCLUSIONS: Further investigation is needed in order to identify unknown asbestos uses and consequent exposure, in particular for females. Uncertainty as regards occurrence of asbestos exposure persists in the textile industries where the mesothelioma epidemics have not yet declined. Research hypotheses are addressed on the re-use of jute bags previously containing asbestos, therefore collection of further information on periods and methods of this recycling activity is essential.

[The diffusion of information on the carcinogenicity of asbestos in the Italian scientific community before 1965].

The spreading of information on asbestos carcinogenicity within the Italian scientific community before 1965. The paper deals with the development of recognition of asbestos carcinogenicity within the Italian scientific community. This development was difficult in Italy as in other countries. Articles and other papers in handbooks and congress proceedings, by Italian authors, published in the period 1934-1965, were considered. The first cases of lung cancer in Italian workers exposed to asbestos were observed in 1955-56, the first cases of malignant mesothelioma in 1965. The cases observed were very few, but knowledge on asbestos carcinogenicity became widespread within the Italian scientific community during the fifties (from 1953 on wards) with the publication of several handbooks of occupational medicine.

Characterization of asbestos fibers in pleural tissue from 21 cases of mesothelioma.

Pleural biopsies from 21 patients with pleural mesothelioma and different asbestos exposure were analyzed by means of analytical electron microscopy with the aim of investigating the presence, quantity, types and sizes of asbestos fibers in pleural tissue. The majority of fibers found consisted of ultrathin (< 0.3 micron) and short (< 5 microns) fibers regardless of asbestos types and subject exposure. Concentrations appeared to be poorly related to the estimated exposure level. Fiber dimensions appeared to be the most important characteristic which determined their translocation in the pleural region.

Mortality in the coke oven plant of Carrara, Italy.

A mortality study was undertaken on a cohort of 538 male workers employed at a coke plant in Carrara in the period 1960-1985. The follow-up period ranged from January 1 1960 to December 31 1990, with 10,665 person-years accumulated. A significant excess in mortality for lung cancer was observed: 19 observed deaths vs 10.02 expected deaths using national rates, SMR 190 (C.I. 95% = 114-296), and vs 11.19 expected deaths using regional rates, SMR 170 (C.I. 95% = 102-265). The results suggest the possible influence of this occupation on mortality from lung cancer, as was observed in previous studies performed on larger cohorts of coke oven workers.

The experience of the Mesothelioma Registry of Tuscany in assessing health hazard associated with asbestos exposure.

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.

[Course on smoking cessation organized by the Italian League against Cancer in Florence: determinants of cessation at the end of the course and after 1 year].

The Italian League against Cancer, section of Florence, organizes courses for smoking-cessation groups. Groups meet for 10 sessions throughout 6 weeks; sessions are managed by a psychologist with a cognitive-behavioral approach. In the 53 analyzed courses registered people (693 persons) are mainly women, aged 31-50, with a middle-high level of education. They are heavy smokers with a high level of nicotine dependence and they greatly trust in the course in spite of their previous quit attempts. At the end of the program 66% of registered people (69% of men; 63% of women; p > 0.05) asserts not to smoke anymore. One year later, phone interviews show that 33% of participants (41% of men; 28% of women; p < 0.01) are ex-smokers. After the end of the program the first three months are the higher risk period of relapsing. At the end of the program quitting-smoking predictors are: attendance at at least 7 sessions (OR = 4.26), no more than a high school educational level (OR = 1.71) and smoking less than 30 cig. a day before the course (OR = 1.56). One year later quitting-smoking predictors are: attendance at at least 7 sessions (OR = 2.08), scarce or medium nicotine dependence according to the Fagerström Tolerance Questionnaire (OR = 1.42) and male gender (OR = 1.40).
