A 14-year-old female Jack Russell Terrier presented to discuss radiation therapy for a progressive nasal carcinoma that had failed chemotherapy.
The patient presented to her primary vet early Feb 2017 with epistaxis from her right nostril. She was evaluated by the oncology team in March 2017 and at the time definitive fractionated radiation therapy in Brisbane was declined. She was started on chemotherapy instead and after two doses of mitoxantrone and a dose of carboplatin the tumour was noted to be progressive resulting in significant facial deformity. The owner was considering euthanasia before hearing of stereotactic radiotherapy option.
At presentation the patient had marked facial deformity and swelling over the dorsal bridge of the nose between the eyes. Both eyes retro pulsed normally and there was no evidence of protrusion into the oral cavity. The mass effect was resulting in prominent stertor on inspiration. No obvious discharge was noted on exam. CT simulation for radiation planning was done on the 29/5/2017.
The patient tolerated the treatment well with no acute effects noted on completion of therapy. She had a very good response with marked resolution of the facial swelling during therapy and marked improvement in breathing. She was seen on recheck 6 and a half months later and was doing very well. Some nasal discharge returned 11 months post treatment and the patient was doing well 17 months post treatment with supportive care.
