Feline injection site sarcomas

Abstract

Injection site sarcomas in cats have been the topic of more than 40 articles and over 20 scientific abstracts as well as multiple letters to veterinary journals, articles in the popular press, and Internet-based web sites. With the level of discussion that has surrounded this tumor entity, one might expect that great strides have been made in determining the etiology, epidemiology, and preferred treatment options for this disease. Nearly half of the publications on this subject are review articles, however, and that alone indicates both the high level of interest and the lack of information in this situation. This article summarizes the development of our current understanding of this tumor with regard to areas of research into the cause of injection site sarcomas, epidemiology, and the current standard of care for treatment of this iatrogenic disease.
