Rissetto K, Villamil JA, Selting KA et al: Recent trends in feline intestinal neoplasia: an epidemiologic study of 1,129 cases in the veterinary medical database from 1964 to 2004, J Am Anim Hosp Assoc 47:28, 2011.
Data entered into the Veterinary Medical Database (VMDB) concerning 1,129 feline intestinal tumor patients from 1964 to 2004 was evaluated for inclusion in a large retrospective epidemiologic study. Cases were analyzed by breed, age, year of diagnosis, tumor type, and tumor location. Feline intestinal tumors are relatively uncommon and the incidence of all intestinal tumors for this 40-year time period was 0.4%. The authors found the most common tumor was lymphoma and the most common non-lymphoid tumor was adenocarcinoma (ACA). Small intestinal tumors predominated, with lymphoma being the most common intestinal tumor. This study determined that the large intestine is the most common location for intestinal ACA and that ACA is the most common tumor occurring in the large intestine. The diagnosis of intestinal neoplasia, especially intestinal lymphoma, appears to be increasing in the feline population in the United States. This may be due to improvements in veterinary care and diagnostic capabilities in recent years. The study did note that two high-risk variables for developing intestinal neoplasia are the Siamese breed and increasing age after 7 years. These epidemiological findings may aid veterinarians when recommending diagnostic tests and considering differential diagnoses in patients presenting with gastrointestinal and non-specific signs. [VT]
