Diffuse pleural mesothelioma in Trieste. A survey based on autopsy cases

Area of Science:

• Pathology
• Occupational Health
• Oncology

Background:

• Diffuse pleural mesothelioma is a rare and aggressive malignancy.
• Asbestos exposure is a known etiological factor.
• Understanding geographical and occupational risk factors is crucial for public health.

Purpose of the Study:

• To review necropsy records for cases of diffuse pleural mesothelioma.
• To investigate the association between asbestos exposure and pleural tumors.
• To determine the incidence of diffuse pleural mesothelioma in the Province of Trieste.

Main Methods:

• Retrospective review of necropsy records from the Institute of Pathological Anatomy and Histology, University of Trieste (1971-1977).
• Reexamination of cases diagnosed with pleural tumors or lung sarcoma.
• Analysis of occupational history, focusing on asbestos exposure and shipyard work.

Main Results:

• Twenty-six cases of diffuse pleural mesothelioma were confirmed.
• Occupational history revealed asbestos exposure in 22 cases (84.6%).
• Twelve patients (46.2%) had a history of working in shipyards.

Conclusions:

• A high incidence of diffuse pleural mesothelioma was observed in the Province of Trieste during the study period.
• Occupational asbestos exposure, especially in shipyards, is strongly associated with diffuse pleural mesothelioma.
• These findings underscore the importance of occupational health surveillance and asbestos abatement measures.
