Epidemiological features of canine renal neoplasms.

A retrospective study of medical records from 13 veterinary university hospitals and clinics yielded 73 cases of confirmed primary neoplasms of the kidney and renal pelvis. Analysis of the 34 cases of renal carcinoma revealed no evidence of familial (breed) predisposition, but an excess risk was identified in males, especially during middle life. The morphological and epidemiological features of canine renal carcinoma are similar to those of renal carcinoma in humans. The dog may be a suitable model for further research into the causes of this cancer.
