The Australian Mesothelioma Surveillance Program 1979-1985

Area of Science:

• Occupational health
• Epidemiology
• Pathology

Background:

• Mesothelioma is a serious asbestos-related cancer.
• Accurate incidence data and diagnostic criteria are crucial for understanding mesothelioma.
• The Australian Mesothelioma Surveillance Program was established to address these needs.

Purpose of the Study:

• To analyze preliminary data from the Australian Mesothelioma Surveillance Program.
• To report on the incidence, pathological findings, and exposure history of mesothelioma cases in Australia.
• To investigate occupational and environmental associations with mesothelioma.

Main Methods:

• Analysis of 858 mesothelioma cases diagnosed between 1980 and 1985.
• Review of pathological findings and work/environmental history.
• Calculation of annual incidence rates and analysis of asbestos exposure details.

Main Results:

• The annual mesothelioma incidence rate in Australia was 15 per million population (aged 20+).
• A history of asbestos exposure was reported in 69% of cases.
• Most asbestos exposures occurred between 1930-1959, reflecting the latency period of the disease.

Conclusions:

• Australia had a high mesothelioma incidence rate during the study period.
• Asbestos exposure remains a significant risk factor for mesothelioma.
• Further research is needed to refine diagnostic criteria and ascertainment for accurate international comparisons.
