Hypofractionated radiotherapy provides palliation for a dog with advanced gastric carcinoma

Abstract

An 11-year-old, female, spayed border collie displayed vomiting and diarrhoea for a period of 3 months and presented with severe emaciation. A laparotomy confirmed the presence of a gastric lesion, and histopathologic evaluation revealed a diagnosis of gastric carcinoma. The dog was treated with hypofractionated intensity-modulated radiation therapy and achieved clinical improvement for approximately 3 months after treatment. Given the improvement of clinical signs following treatment in this case, the use of radiation therapy as a treatment option may be explored for palliation for dogs with advanced gastric carcinoma.
