Canine Nasal Tumors Study Guide

Overview and Clinical Importance

Nasal tumors represent approximately 1-2% of all canine neoplasms but account for 60-80% of all respiratory tract tumors in dogs. These tumors are predominantly malignant (approximately 80%) and are characterized by local invasiveness with relatively low metastatic rates at initial presentation. Understanding the clinical presentation, diagnostic approach, and treatment options is essential for the NAVLE examination.

The prognosis for untreated canine nasal tumors is poor, with a median survival time of approximately 95 days. However, with appropriate treatment, particularly radiation therapy, survival times can be significantly extended to 12-19 months or longer.

Epidemiology and Risk Factors

Signalment

Age: Median age at diagnosis is 10 years (range 2-16 years). Dogs with nasal sarcomas may present at an earlier age.
