Objectives of this retrospective, cross\u2010sectional study were to describe safety of and tumor responses for a novel palliative radiation protocol for transitional cell carcinoma in dogs. Included dogs had cytologically or histologically confirmed transitional cell carcinoma of the bladder or urethra, and were treated with 10 once\u2010daily fractions (Monday\u2013Friday) of 2.7 Gy. Thirteen dogs were sampled, with six treated using radiation as first\u2010line (induction) therapy and seven treated using radiation as rescue therapy after failing previous chemotherapy. Within 6 weeks of radiation, 7.6% (1\/13) dogs had a complete response, 53.8% (7\/13) partial response, 38.5% (5\/13) stable disease, and none had progressive disease. Three patients presenting with urethral obstruction had spontaneous micturition restored during the treatment protocol. A single patient with unilateral ureteral obstruction was patent at recheck examination. Median survival time from time of initial diagnosis was 179 days. Median survival time from start of radiation was 150 days. Acute radiation side effects occurred in 31% (4\/13) patients and were classified as grade 1 or 2. No significant late side radiation side effects were reported. No variables examined were identified as prognostic factors. Findings indicated that the reported radiation protocol was safe in this sample of dogs with bladder and urethral transitional cell carcinoma. Future prospective studies are needed to determine utility of this treatment as a rescue therapy in patients with complete urinary tract obstruction.<\/jats:p>","DOI":"10.1111\/vru.12339","type":"journal-article","created":{"date-parts":[[2016,2,3]],"date-time":"2016-02-03T15:22:55Z","timestamp":1454512975000},"page":"341-351","source":"Crossref","is-referenced-by-count":31,"title":["TOLERABILITY AND TUMOR RESPONSE OF A NOVEL LOW\u2010DOSE PALLIATIVE RADIATION THERAPY PROTOCOL IN DOGS WITH TRANSITIONAL CELL CARCINOMA OF THE BLADDER AND URETHRA"],"prefix":"10.1111","volume":"57","author":[{"given":"Kevin","family":"Choy","sequence":"first","affiliation":[{"name":"Department of Veterinary Clinical Sciences Washington State University College of Veterinary Medicine WA 99163"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Janean","family":"Fidel","sequence":"additional","affiliation":[{"name":"Department of Veterinary Clinical Sciences Washington State University College of Veterinary Medicine WA 99163"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2016,2,3]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/B978-1-4377-2362-5.00029-3"},{"key":"e_1_2_7_3_1","first-page":"97","article-title":"Tumors of the urogenital system in dogs and cats.
