Plain-English summary
A group of 112 dogs with nasal tumors were studied to see how different staging systems affected their survival. Most of these dogs had adenocarcinoma, a type of cancer, and those classified as WHO stage II tended to live longer than those in stage III. Among the stage III dogs, those who received a combination of surgery and radiation therapy had a significantly longer survival time compared to those who did not receive treatment. The findings suggest that using CT scans for staging might provide a better understanding of tumor progression and help guide treatment decisions.

Abstract
To evaluate the efficacy of clinical staging based on computed tomography (CT) imaging over the World Health Organization (WHO) staging system based on radiography for nasal tumors in dogs, a retrospective study was conducted. This study used 112 dogs that had nasal tumors; they had undergone radiography and CT and had been histologically confirmed as having nasal tumors. Among 112 dogs, 85 (75.9%) were diagnosed as adenocarcinoma. Then they were analyzed for survival time according to each staging system. More than 70% of the patients with adenocarcinoma were classified as having WHO stage III. The patients classified under WHO stage II tended to survive longer than those classified under WHO stage III. Dogs classified under WHO stage III were further grouped into CT stages III and IV, and CT stage III patients had a significantly longer survival time than CT stage IV patients. In addition, patients treated with a combination of surgery and radiation had a significantly longer survival time than the patients who did not receive any treatment in CT stage III. On the other hand, different treatment modalities did not show a significant difference in the survival time of CT stage IV dogs. The results suggest that WHO stage III dogs may have various levels of tumor progression, indicating that the CT staging system may be more accurate than the WHO staging system.
