Abstract
Objectives: The aim of this retrospective clinical study was to evaluate and report response to treatment with a 10-week maintenance-free COP (COP-10) protocol in a cohort of 27 cats with intermediate or large cell lymphoma. Additionally, to identify any potential prognostic factors for predicting the treatment response.
Materials and methods: The medical records of cats diagnosed with intermediate or large cell lymphoma in a single institution in the period 2014 to 2023 and treated with COP-10 as first-line treatment were reviewed.
Results: Twenty-seven cats were included in the study. The median age was 10 years, 67% of the cats were in stages I to II and the most common anatomical location was alimentary (37%). The overall response rate was 65%, with 38% of cats achieving complete remission and 27% partial remission. For cats achieving complete remission, the median progression-free interval and the median lymphoma-specific survival time were both 1,139 days. For cats in partial remission, the median progression-free interval and the median lymphoma-specific survival time were 53 and 210 days, respectively. Clinical stage was significantly related to treatment response and survival time.
Clinical significance: Treatment with the short protocol COP-10 resulted in remission rates and durable first remissions for cats achieving complete remission comparable to responses seen with longer-duration chemotherapy protocols. The results from this study may impact economic and logistic decisions for owners, as well as the quality of life for patients in the future.
期刊介绍:
Journal of Small Animal Practice (JSAP) is a monthly peer-reviewed publication integrating clinical research papers and case reports from international sources, covering all aspects of medicine and surgery relating to dogs, cats and other small animals. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. JSAP publishes high quality original articles, as well as other scientific and educational information. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of small animal medicine and surgery.
In addition to original articles, JSAP will publish invited editorials (relating to a manuscript in the same issue or a topic of current interest), review articles, which provide in-depth discussion of important clinical issues, and other scientific and educational information from around the world.
The final decision on publication of a manuscript rests with the Editorial Board and ultimately with the Editor. All papers, regardless of type, represent the opinion of the authors and not necessarily that of the Editor, the Association or the Publisher.
The Journal of Small Animal Practice is published on behalf of the British Small Animal Veterinary Association and is also the official scientific journal of the World Small Animal Veterinary Association
