Original publication title: Clinical Stage, Therapy, and Prognosis in Canine Anal Sac Gland Carcinoma

Plain-English summary
A group of 130 dogs with anal sac gland carcinoma (a type of cancer near the rear end) was studied to understand how to better manage and treat this condition. The research found that dogs who received treatment, had smaller tumors, and did not have cancer spread to lymph nodes or other parts of the body had a better chance of survival. The study also developed a new staging system to help vets determine the best treatment options based on the cancer's severity. This approach aims to improve outcomes for dogs diagnosed with this type of cancer.

Abstract
Abstract Background:Reports of canine anal sac gland carcinoma (ASGC) describe varied clinical presentations and management and differing responses to therapy. A unifying approach to clinical stage determination and management of this disease has yet to be presented. Hypothesis:An ordinal clinical staging scheme for canine ASGC can be devised on the basis of responses to therapy for a retrospective cohort of affected dogs. Animals:130 dogs with naturally occurring ASGC. Methods:A simplified clinical stage system and a management algorithm for canine ASGC were derived from retrospective evaluation of a cohort of 80 dogs; applicability of both was then prospectively evaluated in a cohort of 50 dogs. Results:Retrospective evaluation revealed 4 statistically significant negative prognostic indicators for survival: lack of therapy, presence of distant metastases, presence of lymph node metastases, and primary tumor size. Lymph node extirpation was a statistically significant positive prognostic indicator by bivariate analysis. In both retrospective and prospective analyses, the modified clinical stage scheme revealed a significant association with survival time. Conclusions and Clinical Importance: The clinical staging scheme permits differentiation between groups in terms of prognosis and, therefore, decisions on therapy. This will facilitate application of appropriate therapy and enhanced communication and collaboration in further investigations of ASGC.
