Plain-English summary
A group of dogs with oral tumors underwent surgery aimed at completely removing the tumors. The study found that dogs with malignant melanoma and osteosarcoma had shorter survival times after surgery, while those with fibrosarcoma were more likely to have their tumors return. Overall, about 85% of the surgeries achieved clear margins, meaning no cancer cells were left behind. Factors like the type of tumor, how completely it was removed, and the dog's age influenced how long they lived after surgery.

Abstract
OBJECTIVES: To describe the long-term outcomes and prognostic factors associated with curative-intent surgery for oral tumours in a large series of dogs. METHODS: Retrospective review of records for dogs with oral tumours treated with curative-intent surgery. Data collected included signalment, weight, surgical procedure, lymph node staging results, computed tomography results, tumour size, histopathology results including margin evaluation, complications, adjunctive therapies, local recurrence or metastasis, date and cause of death and owner satisfaction. RESULTS: Median cause-specific survival was shortest for malignant melanoma (206 days) and osteosarcoma (209 days). Local recurrence rate was highest for fibrosarcoma (54·2%) and distant metastatic rate was highest for malignant melanoma (30%). Curative-intent surgery resulted in complete surgical margins in 85·2% of cases. CLINICAL SIGNIFICANCE: Results suggest tumour type, completeness of excision, tumour size, and age may affect disease-free interval and cause-specific survival. Fibrosarcoma had a higher risk of recurrence compared to other tumour types.
