GI biopsy for lymphoma
Hi, all -- my four-year-old DSH cat, Lou, has had chronic diarrhea
since January. My vet & I are able to control the symptoms with methylprednisolone and metronidazole, but when we try to wean him off the meds the diarrhea returns in force. Even though the diarrhea was under control with meds for the last few weeks and he's been eating well, he has lost almost two pounds and is now down to about 12 lbs. My vet has suggested a biopsy to check for lymphoma. Her initial thought was that he had IBD, particularly because he's had other inflammatory kinds of problems (a couple of mild bouts with FUS and some seasonal granulomas on his lower lip), but the intractable nature of the diarrhea, plus the weight loss, have her thinking that it could be lymphoma. I adoped Lou as a feral kitten; he has tested negative for FeLV, etc., and also had a recent fecal test to rule out parasites. He's indoor-only. I adore my vet and have complete confidence in her but am looking for a little reassurance as well as guidance on what questions I should ask before we proceed with a biopsy. It's an invasive surgery; my vet says that endoscopic biopsies simply don't get enough tissue for a true assessment. I hate to put Lou through the surgery, but it sounds like it's necessary if we're going to figure out the best way to treat him. Anyone have experience with this kind of biopsy? If it does turn out to be lymphoma, what can I expect? And if it's simply a raging case of IBD, can Lou stay on high doses of steroids for the long term? He's now on 4 mg of methylprednisolone twice daily, and in the past has done okay weaning down to 4 mg every other day, but anything below that and the diarrhea flares up again. Thanks for any insight you're able to offer. |

GI biopsy for lymphoma
I think your vet's suggestion of a biopsy sounds reasonable. My cat who died
last year (of a sarcoma) had IBD for about 10 years. She remained on Prednisone for that period of time since she was unable to be weaned off of it. She took a tablet once daily (can't remember the mg). She did very well, as you can see. It's possible that your cat only has IBD, as opposed to lymphoma. I think IBD, however, increases the probability of a cat developing intestinal lymphoma. Keep us posted. Thankfully your cat is young, and is not that thin so he will probably do fine with the surgery. Gail wrote in message ps.com...
