Plain-English summary
A 5-year-old spayed female Shih Tzu was diagnosed with a nasal tumor and received radiation therapy over nearly two years to treat it. The treatment aimed to minimize damage to surrounding healthy tissues and was delivered in three courses, totaling 117 Gy. While the dog experienced some reduced tear production as a side effect, she tolerated the treatment well. Unfortunately, she later passed away due to the spread of the cancer 694 days after the first round of radiation therapy.

Abstract
A 5-year-old spayed female Shih Tzu was referred for evaluation of a nasal transitional carcinoma. A total lifetime dose of 117 Gy was delivered to the intranasal mass in three courses over nearly 2 years using fractionated intensity modulated radiation therapy (IMRT) to spare normal tissues. Clinically significant late normal tissue side effects were limited to bilaterally diminished tear production. The patient died of metastatic disease progression 694 days after completion of radiation therapy course 1. This case demonstrates that retreatment with radiation therapy to high lifetime doses for recurrent local disease may be well tolerated with IMRT.
