003 1458 7 The data show, that asbestosis of the lung goes in a number of cases hand in hand with pulmonary cancer. This occurrence could be a coincidence (Gloyne, Wood). But in 1h ese 6 cases that were observed in de tail, there were so many characteristics that were repeated, that fte cancer in the asbestosis lung seems to be of a causal relation. Pirst of all, the email number of the case should be explained. The number of the workers that are at risk in the asbestos plants is by far smaller thatri the overall number of employees in the factories. Por example, the^umber people that might be concerned in Germany is estimated only to be a few thousand. Only a fraction of those really work in the asbestos dust. Furthermore, many of the employees are women, and they are often only for short periods of time, as are the men. According to English, American, and German authors, it takes several) years for noticeable symptoms or objective signs to appear that Bhow the inhaled dust. Thus, we can not operate with large numbers , where our problem is concerned. Furthermore, the attention about the occupation-related asbestosis has not been been atlTacted for long. The great majority of the papers of the medical field in England dates back to the years 1927 - 29 (cf. lit.) In Germany the asbestosis of the lungs has only been dis cussed in detail since 1931 / 32 - with the exceptions of the two forerunners Marchand (1906) and Fahr(l914). The same is true for the United States. Our chart shows very clearly that the studies which are especially dedicated to our problem, were published within the last three yeare. Nothing is more natural than having the detailed study of a disease only when the disease itself is known in its main symptoms. If we can only expect small numbers, we can only use the dead patients for the deliberation of the occupation-related cancer of the asbestos workers. In Germany 12 dissections are known, including my own, two of those had cancer, ca. 17#. In Hannover 3 cases wer dissected, two of which were cancrous, another, 4. case, with unfavourable prognosis, is under medical care, and is, probSiy, wilhout complications of can cer, that means then ca. 50# carcinoma. The number of the actually dissec ted cases in Germany is probably not much larger, due to the scant pub lications. In England there is a survey of 100 cases, which were ob served by Vood. JO# of these are combined with tuberrculosis, 17# not PRODUCED BY FORD
