Between 1978 and 1986, nine cats with nasal tumors were treated with radiation therapy. Rhinotomy was performed in six cats and diagnostic biopsy procedures were performed in three cats. For four of the specimens, a histologic review was significantly different from the initial diagnosis. At the time of analysis, one cat was alive and disease free 26.3 months after the first radiation therapy treatment; two of the cats were dead as a result of local recurrence, four were dead because of unrelated causes, and two were dead of unknown causes. The mean and median survival of cats in this study were 27.9 and 20.8 months, respectively, following the first radiation therapy. There was a 66.7% one‐year, 44% two‐year, and 33% three‐year survival rate. Complications of the surgery and radiation therapy were minimal. In conclusion, the histologic evaluation of nasal neoplasms in cats is not straightforward and may require specialized histologic technics for accurate diagnosis. Radiation appears to be safe and may be efficacious in local control of feline nasal tumors.
