This study analyses survival of Tuscan residents (Italy, 3.5 million population) diagnosed by histological examination with malignant pleural mesothelioma (MPM) during the period 1988-2000, and recorded in the Tuscan Malignant Mesothelioma Register. The aim was to establish the prognostic role of demographic, diagnostic and asbestos exposure variables. During 1988-2000, 381 MPM cases were recorded (318 men; 63 women). Vital status was ascertained up to 31 December 2002. No cases were lost to follow-up. Median survival of certain MPM was 324 days (11 months; 95% CI 297-366); 45.7% (95% CI 40.6-50.6%) survived more than 1 year; 24.2% (95% CI 20.0-28.5%) more than 2 years. In univariate and multivariate analyses survival was associated with histological subtype (epithelioid subtype had the longest survival). Gender, age, period of diagnosis, hospital of diagnosis and asbestos exposure did not show significant effects. Therapeutic information was available for patients of the period 1997-2000. There was no significant difference in survival between treated versus untreated patients. In conclusion, no advance in prognosis at the population level in the most recent period can be suggested on the basis of the data available to the Tuscan Malignant Mesothelioma Register.
