Abstract

This letter reports some constructive observations on the recent findings by Jiang et al. Cancer Sci (2016) that have inspired a more general comment on how the research on asbestos should take advantage of the different existing multidisciplinary perspectives so to flow into a final comprehensive model of asbestos‐induced carcinogenesis.

In plain English

This is a letter to the editor, not a research study, and it reports no new data. The author commented on work by Jiang and colleagues, which pointed to local iron overload linked to UICC chrysotile and crocidolite as a major cause of asbestos-induced mesothelial carcinogenesis. Those researchers claimed that removing iron from the mesothelial environment could help prevent it. The author argued that the work took a single perspective (pathology) and lacked a basic general model. The author raised several issues. Because the origin of iron overload is still debated, the role of iron within the fibers' own structure should not be ruled out. Part of the scientific community sees asbestos bodies as a defense mechanism rather than a threat. It matters whether the iron is Fe2+ or Fe3+. Pleural macrophages and phagocytosis should also be considered. Finally, the statement that chrysotile is apparently a stronger carcinogen than crocidolite needs further experimental evidence. The author concluded that researchers from different fields working together is the only key to understanding these mechanisms.

What the study did and found

• Design: Letter to the editor (commentary on another group's published work); no new data
• Who was studied: No study population; the letter comments on published research by Jiang and colleagues on asbestos-induced mesothelial carcinogenesis
• Exposure: UICC chrysotile and crocidolite and the role of iron overload, as studied by Jiang and colleagues; the letter itself tested no exposure
• Main results:
  • The letter described Jiang and colleagues' claim that eliminating iron from the mesothelial environment could help prevent asbestos-induced mesothelial carcinogenesis
  • The author argued that the Jiang report lacked a basic general model and a multidisciplinary perspective
  • The author argued that, since the origin of iron overload is controversial, the role of iron in the fibers' own structure should not be ruled out
  • The author noted that part of the scientific community considers asbestos bodies a defense mechanism rather than a threat
  • The author asked whether iron overload concentrates Fe2+ or Fe3+, which the author said matters for producing toxic reactive species
  • The author argued that pleural macrophages and phagocytosis, not only mesothelial cells, should be considered
  • The author argued that Jiang and colleagues' conclusion that chrysotile is apparently a stronger carcinogen than crocidolite requires further experimental evidence
• The authors' conclusion: The author concluded that sharing perspectives across disciplines (such as biochemistry, mineralogy, crystallography and toxicology) is the only key to disclosing the mechanisms of asbestos-induced carcinogenesis
