Plain-English summary
A group of 64 dogs with oral tumors on their lips and mouth underwent surgery to remove these growths. Most of the dogs, about 95%, were still alive after the surgery, with an average survival time of over 23 months. Only a few dogs had tumors come back, and those that did were still alive at the end of the study. The findings suggest that dogs with these types of tumors can expect a good outcome and long survival after having the tumors surgically removed, without needing additional treatments.

Abstract
Postsurgical follow-up information was obtained on 64 dogs with 69 histologically well-differentiated melanocytic neoplasms that involved the mucous membranes of the lips and oral cavity. The patients received no adjunct therapy. Sixty one of 64 dogs (95%) were alive at the end of the study or had died of causes unrelated to the tumor, with a mean survival of 23.4 months and a median survival of 34 months after surgery. Twenty-eight dogs alive at the end of the study had a mean survival of 31.3 months after surgery. There were 2 dogs, which had recurrent tumors, that were still alive at the end of the study. All dogs that died of tumor-related causes (3) and all dogs with recurrent tumors (2) had tumors in the oral cavity. Results of this study indicate that a favorable clinical course and prolonged survival can be expected in most dogs with histologically well-differentiated melanocytic neoplasms of the mucous membranes of the lips and oral cavity, with only local excision of the lesions and no adjunct therapy.
