In plain English

This is a short letter to the editor from a single author in Sydney, Australia. It was not a research study and reported no new data; it put forward a hypothesis. The author described pleural plaques as involving the parietal pleura but not the visceral pleura, arising where the two pleural layers move most against each other with breathing, coughing and sneezing, not occurring over the lung apices, and tending to group deep to the ribs. The author asked whether plaques and later mesothelioma might result from chronic abrasion of the parietal pleura by asbestos fibers at the lung surface, a mechanical cause rather than chemical carcinogenesis, and suggested that pressure from the ribs during coughing might explain where plaques form. The author then asked whether prophylactic pleurodesis might help prevent mesothelioma by preventing this abrasion, noting it may be arguable whether even a low-morbidity procedure should be proposed for everyone, and suggested that factors such as plaque load, life expectancy, smoking and chronic cough might identify higher risk groups. No specific asbestos fiber type was named.

What the study did and found

• Design: Letter to the editor proposing a hypothesis; no new data, patients or measurements were reported
• Who was studied: No study population. The letter discusses asbestos-related pleural disease in general. The single author is listed in Sydney, Australia.
• Exposure: Inhaled asbestos fibers in general, described as relatively long; no fiber type (such as chrysotile, amosite or crocidolite) was named
• Main results:
  • The author described pleural plaques as involving the parietal pleura and not the visceral pleura (a description, not a new finding)
  • The author stated that plaques arise in areas of greatest movement between the pleural layers and do not occur over the lung apices
  • The author stated that plaques tend to group deep to the ribs
  • The author asked whether plaques and mesothelioma might result from chronic abrasive trauma by fibers, implying a mechanical cause rather than chemical carcinogenesis
  • The author suggested that during coughing the increased pressure exerted by the ribs on the pleural space may explain where plaques tend to form
  • The author suggested that factors possibly including plaque load, life expectancy, smoking and chronic cough might identify higher risk groups for whom intervention may be justified
• The authors' conclusion: The author raised, as a question, whether prophylactic pleurodesis might have a place in preventing mesothelioma by preventing chronic abrasion between the pleural surfaces
• Limitations the authors state:
  • The author noted it may be arguable whether even a low-morbidity procedure should be universally proposed
