2017 ACVIM Forum Research Abstract Program

Records were collected retrospectively from six academic and private practice institutions, and were reviewed for data regarding surgical procedure, neurologic function, adjunctive therapy and survival. Sixteen cases were included, all of which received decompressive surgery. Of those cases, 1 dog was treated with chemotherapy and 3 dogs were treated with both chemotherapy and definitive radiation therapy. All dogs either improved neurologically following surgery or remained stable neurologically with improved pain control. All were large breed dogs with an average age of 9 years. Median survival time for dogs treated with surgery alone (n = 12) was 43.5 days (range 3-1333). One outlier was still alive 4 years after surgery alone. The one dog treated with chemotherapy survived 56 days. Dogs treated with radiation therapy and chemotherapy (n = 3) had a median survival time of 257 days (rage 223-270). In most cases where follow up was available, dogs were euthanized due to recurrence of the primary tumor or return of original clinical signs.
