Mandibular resection for removal of oral tumors in 30 dogs and 6 cats.

Abstract

In 30 dogs and 6 cats with oral tumors involving the mandible or soft tissues adjacent to the mandible, the tumors were removed by mandibular resection. The most common tumors in the dog were malignant melanoma (10 cases; 33%) and squamous cell carcinoma (8 cases; 27%). The most common tumor in the cat was the squamous cell carcinoma (5 cases; 83%). Thirteen dogs (43%) were evaluated as locally tumor-free at a median follow-up of 15.4 months. Local recurrence of tumor and/or metastasis was evident in another 10 dogs (33%). Four of the 6 tumors in the cat recurred within 8 months.
