Methods by which mesothelioma can be diagnosed (1973)

This conference paper is mainly a commentary by one author, not a formal research study, though it includes some clinical observations. It ends with notes on the spoken presentation and a discussion with other participants. The author reviewed how pleural tumours were named and classified and argued that much of the past difficulty was about terminology. The author stated that pathologists now have reasonably valid criteria for diagnosing mesothelioma at autopsy, on biopsy, and from cells in pleural or peritoneal fluid. The author said false negative results on pleural needle biopsy are more common than false positives, and that the biopsy sometimes had to be repeated five times. In the presentation, the author said a history of asbestos exposure was found by careful questioning in all of the last 60 mesothelioma cases at the National Research Institute for Occupational Diseases clinic. In the discussion, another participant, Hammond, criticized such questioning without a control group as producing large bias. The author concluded that earlier diagnosis gives better therapy results, and that fluid cytology and needle biopsy are useful for this.
