Identifying High-Risk Occupations for Mesothelioma: A Review of Epidemiological Studies

Abstract

Mesothelioma, a rare and aggressive cancer, is primarily caused by exposure to asbestos. This review synthesizes findings from epidemiological studies to identify occupations with significantly elevated mesothelioma risk.

Methods:

A comprehensive literature search was conducted in PubMed, Scopus, and Web of Science databases using relevant keywords (e.g., “mesothelioma,” “asbestos,” “occupation,” “risk factors,” “epidemiological studies”). Studies included were observational studies (case-control, cohort) that investigated the association between specific occupations and mesothelioma risk.

Results:

• Construction:
  • Insulation installers: Consistently identified as a high-risk occupation due to direct handling and installation of asbestos-containing insulation materials.
  • Demolition workers: Exposed to high levels of asbestos dust during the demolition of older buildings.
  • Carpenters, plumbers, electricians: Frequently encounter asbestos-containing materials during construction and renovation projects.
• Shipbuilding and Ship Repair:
  • Shipyard workers, including welders, insulators, and pipefitters, face significant exposure during ship construction, maintenance, and repair.
• Mining and Manufacturing:
  • Asbestos miners: Directly involved in the extraction and processing of asbestos ore.
  • Workers in asbestos manufacturing: Involved in the production of asbestos-containing products (e.g., textiles, automotive parts).
• Other High-Risk Occupations:
  • Firefighters: Respond to fires in older buildings where asbestos-containing materials may be present.
  • Automotive mechanics: Exposed to asbestos in brake linings and clutch plates.
  • Pipefitters and Plumbers: Handle and work with asbestos-containing pipe insulation.
  • Electricians: May encounter asbestos in older electrical wiring and equipment.
  • Boilermakers: Work with asbestos-containing materials in the construction and maintenance of boilers.
  • Aerospace workers: May encounter asbestos in aircraft components, such as brakes and insulation.
  • Railroad workers: Exposed to asbestos in older railroad cars and locomotives.

Limitations:

• Data Limitations:
  • Recall Bias: Accurate recall of past occupational exposures can be challenging, especially for events that occurred decades ago.
  • Occupational History Data: Detailed occupational history data may be incomplete or unavailable for many individuals.
  • Exposure Assessment: Accurately quantifying past exposure levels can be difficult.
• Confounding Factors:
  • Smoking: Smoking is a significant risk factor for lung cancer and can confound the association between asbestos exposure and mesothelioma risk.
  • Other Environmental Exposures: Exposure to other environmental pollutants can also influence the development of mesothelioma.

Conclusions:

This review highlights the significant occupational risks associated with mesothelioma. Continued research and surveillance are crucial to identify emerging high-risk occupations and implement effective prevention strategies.
