Prognostic factors associated with survival two years after surgery in dogs with malignant mammary tumors: 79 cases (1998–2002)

Abstract

Results suggest that tumor stage, tumor size, and OHE status were significant prognostic factors associated with survival 2 years after surgery in dogs with malignant mammary tumors. Further, either dogs with tumors > or = 5 cm in diameter or dogs with tumors present for > 6 months prior to surgery had a higher risk of having lymph node metastases.
