Much discussion has taken place regarding the liability of the stomach to carcinoma as compared with that of the other organs of the body. Brinton considered that the gastric lesion constituted about 33 per cent, of all primary cancers; Virchow estimated it at 34.9 per cent.; d'Espine at 44.37 per cent.; Tanchou at 25.2 per cent.; Salle at 31.9 per cent.; Welch at 25.7 per cent.; Haberlin at 41.5 percent.; Holsti at 53.9 per cent.; Eisenhart at 18.92 per cent.; Reiche at 35.5 per cent. ; and Riegel at 50 per cent. Out of 3,0112 primary carcinomata the diagnoses of which were verified after death, the stomach was the seat of the growth in 1,006, or in 33.4 per cent., and the uterus in 984, or in 32.6 per cent. ; while among 43,894 unverified cases included in various bills of mortality, 10,442, or 23.7 per cent., presented disease of the stomach, and 8,900, or 20.2 per cent., of the uterus. It is worthy of notice that the relative liability of the two organs seems to vary considerably in different places. Thus, in England the ratio of gastric to uterine carcinoma is about 7:6; in Hamburg, nearly 2:1; in Berlin, 7:5; in Prague, 7:6; in Wurzburg, 7 : 4; in, Helsingfors, 7 : 1, and in Geneva, 3 : 1. In New York and Paris and in Australia the two organs are said to be equally affected, while in Vienna the uterus is apparently more frequently diseased than the stomach. Two conclusions may be drawn from these facts : (1) That at least 50 per cent, of all primary carcinomata develop either in the stomach or in the uterus ; (2) that while the uterus is relatively more often affected, since it is a viscus of one sex only, the stomach is absolutely the most frequent seat of the disease, and its lesion constitutes 30-35 per cent., or about onethird, of all primary carcinomata.
