FELINE SINONASAL NEOPLASIA: A CAT'S NOSE IS NOT A SMALL DOG'S NOSE!

摘要

Sinonasal tumors are not very common in cats, representing less than 1% of all cancers in that species. However, the quality of life of the occasional feline patient with sinonasal tumors will be negatively affected, since these space occupying lesions can be fairly invasive and destructive, leading to pain, decreased appetite and lethargy. Contrary to dogs, where carcinomas and sarcomas are most common, lymphomas are among the most frequently encountered sinonasal tumors in cats. Epithelial tumors (carcinomas) are also commonly encountered, while mesenchymal tumors (sarcomas) are rare. The published veterinary literature is relatively scarce regarding survival time in cats with sinonasal neoplasia receiving radiation therapy as the main therapeuticmodality, with less than 30 cases treated with megavoltage irradiation in the literature in English. Furthermore, and contrary to canine sinonasal tumors, at this time there is no published advanced imaging-based staging system for feline sinonasal tumors.
