Plain-English summary
A group of 21 dogs with adrenal tumors underwent surgery to remove the growths. Out of these, 18 were found to be cancerous, and while four dogs sadly passed away during or shortly after surgery, the majority of the surviving dogs showed improvement in their symptoms. For two dogs whose tumors were not completely removed, a medication called mitotane was used to help manage their condition. Overall, dogs with cancerous tumors lived for an average of about 778 days after surgery, while those with benign tumors had varied outcomes.

Abstract
Twenty-four adrenocortical tumors were surgically removed from 21 dogs. Histopathological examination confirmed 18 carcinomas and six adenomas. Four dogs died in the perioperative period. Fifteen of the 17 dogs that survived the perioperative period had long-term resolution of their clinical signs. Two dogs with incompletely resected tumors were treated with mitotane to control their clinical signs. Overall median Kaplan-Meier life-table survival for dogs with carcinomas was 778 days (range, one to 1,593 days). Median survival for dogs with adenomas was not reached (range, 11 to 730 days). Histopathological diagnosis, histopathological cellular features, age of the dog, and tumor size were not prognostic of outcome.
