Book Description
Excerpt from The Journal of Cancer Research, 1917, Vol. 2 The literature on tumors in mice does not furnish satisfactory information concerning the frequency of sarcomas among them. Statistics on other animals indicate that with most species, as with man, sarcoma is much less common than carcinoma. Caspar (1), in his review on the tumors of animals, published twenty years ago, makes the statement that sarcomas behave in animals quite the same as the corresponding tumors in man, and are more malignant than carcinomas, with much more extensive metastasis and rapid post-operative recurrence. They are, according to the literature reviewed by him, the moat common tumors of dogs and horses, but it is to be considered that in the earlier literature there are many granulomas mistakenly diagnosed as sarcoma. Frohner (2), in 644 operated tumors in dogs, found 44 sarcomas. In rats, sarcomas seem to be especially frequent. McCoy (3) found, in 100,000 rats killed in plague work, 103 tumors, of which 30 were diagnosed as sarcomas and 18 fibromas. Of the sarcomas, 18 were found in the liver, 5 in the subcutaneous tissues, and 5 in the mesentery, and 1 each in the testicle and the pelvis. This predilection of the liver is corroborated by Woolley and Wherry (4) who found in 22 spontaneous tumors in rats, including 7 sarcomas, 3 sarcomas of the liver, which were, as in many of McCoy's cases, associated with parasites (5).
