How likely is cat intestinal lymphoma to spread to the kidneys?

Updated On September 23rd, 2025

Pet's info: Cat | Siamese | Male | neutered | 8 lbs

I have read that "T-cell lymphoma (mucosal and transmural) were almost exclusively localized to the the gastrointestinal tract - small/large intestine and the stomach." Can you comment on how true is this statement? How likely it is that a small intestinal lymphoma would spread to the kidneys? Thank you so much for sharing your views.

Thanks for using Petco Pet Education Center, formerly Petcoach! That statement is true for the most part. There are more factors that play a role when it comes to ymphoma such as the morphology of the cells and their molecular characteristics. Now it is true that most of the lymphomas affecting the gastrointestinal tract in cats are T-cell. However, we do see T-cell lymphoma affecting other locations. The small cell type of gastrointestinal lymphoma does not tend to affect the kidneys at all while the large cell type can affect the kidney in about a third of the patients. I hope this is useful. To give you more specific information I would need to know more specifics on the case. Feel free to request a consultation with me if you have further questions such as best treatment options and how to manage these cases. I see these cases very commonly as I only see cancer cases. Good luck!
