In plain English

This article, from the Clinica del Lavoro of the University of Milan, was a case report followed by the author's discussion of published work on lung cancer in people with asbestosis. It described a woman born in 1905 who worked as a spinner in an asbestos factory from 1921 to 1944 and from 1946 to 1952, 29 years in all. She died in 1954, aged 49. The autopsy could only be done in June 1954, more than a month after her death in March. It found fibrosis of the lung with asbestos needles, and a lung tumor that was probably a small-cell carcinoma (microcitoma). Her asbestosis was described as slight. The author called this the first case of lung carcinoma in asbestosis observed in Italy. The authors' periodically repeated survey of asbestos workers, and their search among people with asbestosis compensated by INAIL in Italy (115 at the time), had found no other lung cancers. The author concluded that great caution was needed before accepting that asbestos causes cancer, because experimental studies were few and conflicting. The author also suggested that asbestos of different origin and quality might differ in cancer-causing power.

What the study did and found

• Design: Case report (one autopsied patient) with a discussion of the literature
• Who was studied: One woman, born 1905, a spinner in an asbestos factory in Italy, who died in 1954 at age 49; seen at the Clinica del Lavoro, University of Milan
• Exposure: Work as a spinner in an asbestos factory from 1921 to 1944 and from 1946 to 1952 (29 years). The fiber type used in her factory is not stated. In the discussion, the author notes that Italian factories mainly used Canadian or Italian white asbestos and only minimal percentages of blue asbestos.
• Main results:
  • Diagnosis after microscopic examination: fibrosis of the lung tissue with asbestos needles present, and a lung tumor, probably a small-cell carcinoma (microcitoma)
  • Asbestos needles were found in parts of the fibrotic right lung
  • The asbestosis in this patient was described as slight
  • The diagnosis made during her life was confirmed at autopsy
  • The author describes this as the first case of lung carcinoma in a person with asbestosis observed in Italy
  • The authors conducted a periodically repeated survey among asbestos workers
  • The text also refers to workers with asbestosis compensated as such by INAIL in Italy, 115 at the time. Apart from the case described, these inquiries gave similarly negative results for lung cancer.
• The authors' conclusion: The author concluded that maximum caution was needed before accepting the cancer-causing power of asbestos as demonstrated, because experimental studies were few and discordant. As a working hypothesis for further research, the author proposed that asbestos of different origin and quality might have different cancer-causing power.
• Limitations the authors state:
  • The death was learned of only after more than a month, so the autopsy could only be performed on 2 June 1954, and some tissues showed putrefaction
