Current Trends in Survivorship of Radiologists.
Final Progress Report :28 pages
A study was made of the deaths of physicians who entered the Radiological Society of North America (RSNA), the American College of Physicians (ACP), the American Academy of Ophthalmology and Otolaryngology (AAOO), the American Roentgen Ray Society (ARRS), and the American Association of Pathologists and Bacteriologists (AAPB) societies from the 1900's through 1969. Mortality statistics through the year 1974 were available. The findings indicated an excess risk of cancer and of all cause mortality in radiologists. The early cohorts of radiologists showed a significant excess risk of leukemia, skin cancer, and aplastic anemia compared to the other groups of physicians. After 1940, all entrants into these cohorts demonstrated no excess risk of leukemia, a slight excess of skin cancer which was not significant, and no excess risk of aplastic anemia or of lymphosarcoma. An excess risk of multiple myeloma appeared in radiologists and a slight excess in otolaryngologists. About a 1.2 to 1.4 fold excess risk of circulatory disease was also noted in all of the cohorts since the beginning, with no change in the more recent years of data collection. In radiologists, the risk of all cause mortality appeared to begin about 8 to 9 years following entrance into the specialty and remained higher through the life span of those involved in this field; the high risk of all cancers appears to occur 10 to 12 years after entering the specialty. Oral cancer also appeared to be higher among radiologists, however, the author suggests that this may be related to personal characteristics of this population rather than exposure to radiation; fluoroscopy or other practices requiring proximity of face and head to the radiation source may also have played a role.
