Abstract

Introduction: Malignant pleural mesothelioma onset in workers exposed to asbestos is well known with reference to multiple working sectors. In some cases, occurring among workers of sectors characterized by a presumed lower relevance of asbestos exposure, the absence of a well-defined correlation can prevent their emergence and compensation. To improve definition of these cases, this article underlines the importance of a standardized approach to occupational anamnesis.

Methods: Thorough standardized occupational health assessment method application in a case of pleural malignant neoplasm occurred in a hauler, a job generally not associated with high levels of exposure to asbestos fibres.

Results: Assessment of malignant pleural mesothelioma diagnosis and dual mode relevant occupational exposure to asbestos during both truck driving and loading and unloading operations of asbestos-containing goods.

Conclusions: Systematic occupational medicine assessment with accurate standardized approach is essential for reconstruction of asbestos exposure, in order to highlight every aspect useful to establish causal link between cases of pleural mesothelioma and possible occupational and non-occupational exposure to the mineral, even in cases where the first-level occupational history does not appear to be suggestive.

In plain English

This article is a case report about a single worker. The author applied a standardized asbestos-exposure questionnaire, the one indicated by Italy's National Mesothelioma Registry (ReNaM), to a 73-year-old man from the province of Venice. He was seen in June 2018 after he himself asked for an occupational medicine assessment. He had epithelioid pleural mesothelioma, and scans showed calcified pleural plaques. He died in August 2018. Autopsy confirmed pleural mesothelioma with peritoneal extension, although a count of asbestos corpuscles in lung tissue was negative. The questionnaire and signed co-worker statements showed that from 1966 to 1998 he worked as a truck driver ('hauler'). He loaded and unloaded asbestos and asbestos-containing goods by hand, often carried in jute bags, without protective equipment. He also made repairs in the truck's engine compartment. The time from starting this work to diagnosis was 52 years. The author identified a plausible causal link with occupational exposure, and the disease was recognized as occupational. The author concluded that a standardized assessment can reveal asbestos exposure even when a first-level work history is not suggestive.

What the study did and found

• Design: case report (single patient) applying a standardized occupational exposure questionnaire
• Who was studied: one 73-year-old man living in the province of Venice, Italy, seen in June 2018, with pleural mesothelioma; he had worked as a farmer, served in the military in 1966, and worked as a hauler for two trucking companies in Venice from 1966 to 1998
• Exposure: Manual loading, unloading and transport of asbestos and asbestos-containing materials (dust, flakes, slabs, pipes, fireproof clothing, gaskets, flanges, panels, corrugated sheets and flat plates), often in jute bags until the late 1970s, with no protective devices. He also did repairs and routine maintenance in the truck engine compartment and drove FIAT and Mercedes-Benz trucks. The fiber type is not stated.
• Main results:
  • Autopsy diagnosis in this patient: epithelioid pleural mesothelioma with peritoneal extension
  • CT scan showed calcified pleural plaques in this patient
  • The asbestos corpuscle count in lung tissue at autopsy was negative
  • The patient died in August 2018 of cancer cachexia
  • No exposure was found from farm work or military service
  • Latency from the start of hauler work (at about age 21) to diagnosis (age 73) was 52 years
  • The assessment identified two modes of occupational exposure: handling of goods, and the hauler activity itself
  • The author identified a plausible causal link between occupational exposure and the pleural tumour
  • The disease was officially recognized as caused by occupational asbestos exposure
• The authors' conclusion: The author concluded that a standardized approach makes it possible to identify possible asbestos exposure scenarios even when a first-level occupational history is not suggestive. The author advised an occupational medicine assessment for all asbestos-attributable neoplasms at the time of diagnosis.
