What's New in the Treatment of Canine Anal Gland/Anal Sac Carcinoma (AGASACA)

1.0 CE Credit Hour / Veterinarians & Veterinary Technicians Track: Oncology

Overview:

Tumors of the anal sac are uncommon and represent a small percentage of all skin tumors in dogs (< 2%). The most common malignant tumor of the perianal region is the anal sac (gland) carcinoma, accounting for 15–20% of all perianal tumors. These tumors are locally invasive and metastasize early in the disease. The average age of dogs diagnosed with this disease is 10–11 years, and there does not appear to be a breed or sex predilection. This lecture will describe the clinical presentation, staging, and best treatment options for dogs with AGASACA.

Learning Objectives

  • Overview of the anal sac (gland) carcinoma, which accounts for 15–20% of all perianal tumor and an anal sac mass is noted as an incidental finding in nearly 50% of cases
  • Learn that hypercalcemia is a poor prognostic factor and is noted in ~27% of all cases.
  • Examine hypofractionated radiation therapy as a good palliative option for nonresectable disease
  • Nodal involvement can be treated with curative intent (surgery) or more palliatively with Palladia or hypofractionated radiation therapy
  • Understand the rarity of Bilateral disease.
