Mesothelioma in Relation to Asbestos in the United States - (1964)

Mesothelioma and Asbestos Exposure: Legal Implications of Entiknap and Smither’s 1964 Study

Abstract
The 1964 study, "Mesothelioma in Relation to Asbestos in the United States" by Entiknap and Smither, published in the Brite Journal of Industrial Medicine, provides groundbreaking evidence linking asbestos exposure to mesothelioma. The researchers analyzed 2,500 autopsies from 1953 to 1964, focusing on cases with asbestosis, and reviewed 307 consecutive deaths of asbestos insulation workers from 1943 to 1964. Their findings revealed a significant association between asbestos exposure and mesothelioma, particularly in the pleura and peritoneum. The study also highlighted the challenges of diagnosing mesothelioma due to the absence of asbestos bodies in some cases, emphasizing the need for advanced diagnostic techniques. This research established mesothelioma as a distinct neoplastic complication of asbestos inhalation, separate from lung cancer.

Legal Relevance
This study is a cornerstone for asbestos-related legal claims, providing scientific evidence of the causal relationship between asbestos exposure and mesothelioma. It supports claims of employer and manufacturer negligence by demonstrating that the health risks of asbestos were well-documented by the 1960s. The study’s findings on occupational exposure, latency periods, and the presence of asbestos fibers in lung tissue strengthen arguments for liability. It also counters common defense claims by showing that even low-level or secondary exposure can lead to mesothelioma, emphasizing the pervasive danger of asbestos.

Occupational Groups at Risk
The study identifies several high-risk occupational groups, including:

• Insulation and Fireproofing Workers: Regularly handled asbestos-containing materials.
• Construction and Remodeling Workers: Exposed to asbestos in building materials like cement and insulation.
• Boiler and Furnace Workers: Worked with asbestos in high-temperature environments.
• Shipyard Workers: Extensively exposed during shipbuilding and maintenance.
• Manufacturing Workers: Directly exposed during the production of asbestos-containing products.
• Pipe and Duct Workers: Encountered asbestos in insulation materials.
• Utility and Plant Operators: Operated in industrial environments with asbestos insulation.

These groups faced significant exposure risks, making them particularly vulnerable to mesothelioma and other asbestos-related diseases.

Current Medical Understanding
The study aligns with modern medical knowledge, which confirms the strong link between asbestos exposure and mesothelioma. While diagnostic techniques have improved since 1964, the study’s conclusions remain valid and are supported by contemporary epidemiological research.
