August 23, 1 957 Mr. Hugh M, Jackson, Manager industrial Health Program Johns-Manville Corporation 22 Dart 4 Oth Street New York ifj, New York Dear Hugh: Thank you for your letter of August 19 regarding the Sep* t ember meeting of the ATI, Ae a matter of fact, having completed tho literature search, it is apparent to ua that the possibility of an association between lung cancor and asbestosis is much more likely to exist in asbestos factories than in mining operations. For example, of 99 cases which had been re ported up to 1955, at loast SO appear to have occurred in asbestos workers other than miners. A number were women, and the occupations given ware: weaver, carder, mattress maker, lagger, bagger, pipe covsrer, spinner, etc, \ , u Two specific article* which mention tho tyy* of exposure and the job la that by Doll (l)aad that by Isselbacber, ejt. al, (2), Seventeen case* studied by Gloyna and 31 reported by MerOwether, as well as three mentioned by Harrison and one each by Coretoa and Owen occurred in DngLsnd. If my Information is correct, there is no mining of asbestos in England, and these must all hay* been workers in textile or similar jobs. In ibis country, the ten cases reported were apparently all in textile workers. The first case, reported in 1935 by Lynch and Smith was a weaver In an asbestos factory for 21 years. Iseelbachor's cases involved a contractor's helper engaged in cutting and sawing asbestos board and sorter in an asbestos mill. Mr, Hugh M. Jackson -2. August 23, 1957 The GAMA study is in the final stages which are, of course, the slowest. All of the statistical analysis has been completed, and the report Is 99% written. What remains is mainly minor revisions, typing the manuscript and proofing* It should go to the print shop by the end of this month. I hope this supplies you with what you need for the meeting. If there is anything further, please let me.know and I will try to get it to you in time. Sincerely yours, DCB:la Undo sure Daniel C. Braun, M,D.
