Autologous vaccination for the treatment of equine sarcoids: 18 cases (2009-2014).

Abstract

The purpose of this retrospective case series was to assess the outcome of an autologous vaccination procedure on single and multiple sarcoid lesions, determine complication rate, and report owner satisfaction. Medical records (18 cases) from January 2009 through May 2014 were evaluated to identify horses undergoing the procedure. Signalment, number, size, anatomic location of lesions, and type of historical treatment were recorded. Follow-up was obtained via standardized owner survey, veterinary examination, and digital images. Data recorded and analyzed included ancillary therapies post-procedure, decrease in number and/or size of sarcoid lesions, sarcoid regrowth, complications, and owner satisfaction. There was a decrease in number of lesions observed by owners in 75% of cases and a decrease in size of sarcoids in 93.8% of cases. Clinical regression observed by owners was noted in 68.8% of cases. There were complications in 43.8% of cases and owner satisfaction in 75% of cases.
