Nasal tumors in the dog: retrospective evaluation of diagnosis, prognosis, and treatment

The records of 43 dogs with nasal tumors (1969- 1974) were evaluated in retrospect. The median age at diagnosis was 10 years. Most affected dogs were bloody nasal discharge, sneezing, and nasal bone deformities. A new method of obtaining tissure for cytologic and histologic evalution proved to be accurate in making a definitive diagnosis in 50% of the cases evaluated. Affected dogs were treated by surgery, surgery plus immunotherapy, or not at all. The results of those treated by surgery alone were no better than those not treated.
