Use of an electronic brachytherapy surface applicator to treat an epiglottal fibrosarcoma in a dog.

Presented is the case of an epiglottal fibrosarcoma in a dog. The location of the mass resulted in challenges in the delivery of adequate dose to the tumor, and herein we describe the treatment using an electronic brachytherapy source. The treatment consisted of four Gy fractions, twice daily for a total of 10 fractions (40 Gy total). Visual reevaluation two weeks after treatment supported adequate spatial dose delivery, and the patient was reportedly improved six weeks after treatment. We demonstrate that plesiotherapy using an electronic brachytherapy device is feasible and may be useful in the treatment of carefully selected veterinary tumors.
