MEDICAL DEPARTMENT ISHER BODY DIVISION GENERAL MOTORS CORPORATION PIQUETTE AND ST. ANTOINE DETROIT 2, MICHIGAN December 9, 1948 Dr. Robert A. Kehoe University of Cincinnati College of Medicine Cincinnati, Ohio Dear Doctor: At the conclusion of our conversation the other day we met Dr. Blankenhorn for a discussion of the Daye case. I believe Dr. Blankenhorn's views are exactly in agreement with your own, that is that with a possible exception of Benzol, there is no chemical etiology for lymphatic leukemia. Benzol alone has been judged to be a possible cause of leukemia whereas several chemical agents will cause blood changes in the nature of leukopenia without however, any further progression toward a lymphatic leukemia. Dr. Blankenhorn suggested that we rely not only on proving the absence of Benzol exposure in this case but that we present as extensive a picture as possible of our 25 years experience with lacquers without incidence of leukemia, as shown by our relative divisional corporation and national lymphatic morbidity. Some of these figures X quoted to you the other day. We will advise you further when the cose progresses. AFL:ep CC: Mr* Ward N13949 Si: A. I*. Lecklider, M. D. General Medical Director
