Plain-English summary
A group of dogs with anal sac adenocarcinoma (a type of cancer) underwent surgery as the first treatment option. Out of 52 dogs, some experienced minor complications, but overall, the surgery was safe and effective. After surgery, about 12% of the dogs had local recurrences, and 42% developed new cancer in their lymph nodes. For those that needed a second surgery due to recurrence, the average additional survival time was about 283 days. This suggests that surgery can help manage this type of cancer in dogs, even if it comes back.

Abstract
OBJECTIVES: To report the outcomes and complications of a cohort of dogs with primary and recurrent anal sac adenocarcinoma managed with surgery as the first-line treatment. To report the use of lymph node cytology for identification of metastatic disease. METHODS: Retrospective review of case records of a single referral centre population of dogs diagnosed with anal sac adenocarcinoma. RESULTS: Fifty-two clinical cases were identified. Altered ultrasonographic appearance of lymph nodes was highly consistent with metastatic disease as assessed by cytology and histopathology. Seven of 58 (12%) perineal surgeries had reported minor complications and seven (12%) others required further surgical intervention. Minor controllable intraoperative bleeding was the only complication noted associated with lymph node extirpation in two of 39 (5%) metastectomy procedures. Six dogs (12%) suffered local recurrence and 22 (42%) developed subsequent or recurrent nodal metastatic disease. From the time of detection of disease recurrence, median additional survival associated with a second surgical intervention was 283 days. CLINICAL SIGNIFICANCE: Coeliotomy for lymph node metastatectomy in dogs with adenocarcinoma of the anal sac has low morbidity and should be considered in patients presenting with evidence of regional metastatic disease both at initial presentation and with recurrent disease.
