Question 2

Answer 2

Background: Tonsillar carcinomas are rarely reported in dogs. Metastatic typically to local LN. Negative prognostic indicator included presence of clinical signs.
Population: 123 client-owned dogs with diagnosis of tonsillar carcinoma con-firmed by cytology or histopathology. Unilateral disease in 115/123 cases
Results: Overall survival time (OST) was 126 days. MST 186d. Significantly longer survival in dogs without evidence of metastatic disease.
Positive prognostic factors = absence of clinicals signs at presentation, surgery (tonsillectomy), use of adjuvant chemotherapy and use of NSAIDs
Conclusion: Asymptomatic dogs, those treated with surgery, surgery and adjuvant chemotherapy, and NSAIDs may have a better prognosis than previously expected.
