Lymphoma- Calvin's Story

:(Today, my heart horse, my horse of a lifetime, my 10 year old boy was diagnosed with Lymphoma. Devastated and heartbroken only begin to describe how I am feeling.

Ultrasounds and x-rays will be done this week to determine where else, if anywhere, the lymphoma has spread. Additional lab tests will also be done to determine the specific type of lymphoma. By the end of this week I will be presented with various treatment options.

I would happily cut off my arm if it would save this horse. However I will not put him through any unnecessary suffering just to prolong his life for me (the good news is that despite his cancer we have seen no change in his demeanor, eating habits, etc. He even horse showed in mid January and was champion… point being, it does not appear that he is currently suffering).

So, who else has experience with lymphoma? What type of lymphoma was it? Was there treatment? Was it successful?

Sadly, I cannot seem to find a ton of information on successful treatment of lymphoma.

Any thoughts or information will be greatly appreciated.
Thank you!

So sorry to hear of your horse. I know how hard it is. I am wondering if my horse has lymphoma. Can I ask you what symptoms and tests you had done? I have researched lymphoma too and there isn’t much out there.

I am very sorry, but if you want to tal pm me. I am going through he’ll with my heart horse too. We just can’t pinpoint what exactly is wrong.

Good luck with your boy. Hugs to you

My daughter’s horse had lymphoma 2 years ago. He is fine now. She talked with all kinds of people and ended up giving him a short course of chemotherapy that was recommended by a number of vets, including a vet medical oncologist from the University of Florida. I think her horse had a slowly progressive lymphoma, as we were noticing for months that he wasn’t right. Finally, his blood work showed abnormal cells. He did not seem to have any side effects from the chemo, and actually looked healthy and back to normal after just a couple of doses. I was very skeptical that the chemo would be worthwhile, but was so pleased when he did well. I have no idea of cost or of usual effectiveness. Where are you located and what veterinary resources are available to you?

Also, she did not do a big workup on her horse. His CBC and blood chemistries were normal. The pathologist who reviewed the blood smear was the one who made the lymphoma diagnosis, based on the cancer cells on the slide. My daughter’s feeling was that she was going to treat her horse, even if it seemed hopeless. Therefore, she did not want to do any further workup that might have shown things didn’t look good. I don’t know if her horse will have a recurrence, but he has gotten 2 healthy years out of those few doses of ? every 3 weeks chemo.

Thank you

Thank you, thank you a million times over for your response!

My horse is at UPenn’s veterinary hospital, New Bolton. They are fantastic but I am open to the possibility that there may be a better place for him. UC Davis keeps coming up on my internet searches but Florida would be actually be a possibility for us. Once we get a final diagnosis later this week I will know better as to how I should proceed. And a phone consult with UofFlorida may be in order.

Thank you again for sharing your story.

Davinci,
My horse presented with swelling under his jaws in late January. He went to the hospital at that point and has been there since. The swelling turned out to be a somewhat rare, in horses, bacterial infection. Due to the rareness of the infection I’m glad the vets to looked deeper.
Biopsies were taken from several small “tumors” that confirmed lymphoma.

You might want to email the veterinary medical oncologist at the University of Florida and see if they have any suggestions that would make it worthwhile to bring the horse to Florida. Include biopsy reports or other info that will help him decide if there is anything he can offer you. Also, if he wants certain lab tests done, you can have them done at U Penn before you head to Florida. My daughter talked with the UF vet oncologist by email. In his email back to her, he was able to suggest a certain, published, chemo protocol. My daughter is a mixed animal vet in Maryland, so she was able to administer the chemo without taking the horse anywhere. There are not a lot of medical vet oncologists with horse expertise, so she was glad to get info from the medical vet oncologist at UF.

Thank you! This is more information and help than I could have hoped for.

I hope it helps. I was sure we were losing my daughter’s horse 2 years ago. It is so wonderful to have him back to his normal self. Many horses won’t do as well as he did, but treatment is worth looking into. I hope you find a good treatment for your guy, and get him back to good health.

Keep us all posted about what you learn and how he does.

I have news, and its good. Which is shocking. Seriously I’m still in shock.

Midweek, every inch of Cal that could be was ultra-sounded or x-rayed (to look for tumors). Everything looked good. But we were still waiting on the additional tests done on the biopsies that were expected to come on Monday.

In the meantime, I was doing a lot of crying and trying to mentally prepare myself that I was probably going to have to put him down sometime in the near future.

The results that were expected on monday actually came back today (friday) and the form of lymphoma that he has is treatable. Very treatable. This is often not the case. As I understand it, most horses only live weeks once they are diagnosed with lymphoma. With his form, with treatment, and a little luck I am being told that I can expect YEARS of a happy and healthy horse. YEARS. I’m seriously in shock and couldn’t be happier.

So, he is coming home tomorrow!

His vet has been wonderful. She currently has an idea as to how she wants to treat him but she will spend the next several days consulting with oncologists, literally around the world, in order to come up with what she thinks is the best treatment plan.

There is a possibility that he will be treated only with steroids which would mean he would not have to go back to the hospital, however if treatment will include chemo he will have to return for those treatments (no big deal)

This is such amazing and exciting news.

I plan to keep updating this thread as his treatment progresses.


edited to add:
my horse has a cutaneous form of lymphoma called t cell rich large b cell lymphoma.

Glad you got good news. I have a hard time believing he could be in better hands anywhere other than New Bolton. Equal maybe but not better. Jingles for a complete recovery.

Wonderful! Even if he gets chemo, it shouldn’t be a big deal. The vet has to take precautions to protect herself while slowly administering the meds. Then, the manure may need special disposal so no other animal eats it or is exposed to it. It is probably easier to do it at a horse hospital, although it can be done at home.

Wonderful news.

I figured I’d just keep updating this in case someone else is ever in my situation and they find this thread.

First things first, my horse is doing great. He doesn’t know he is “sick” and I continue to ride him.

Its taken a while to get the exact treatment protocol from the consultants. First my guy had to have an echocardiogram as one of the drugs has the possibility to cause cardiotoxicity. Also due to the fact that he is a jumper they want to make sure his heart stays healthy and he will have echos periodically throughout chemo.

So now we have the protocol and my vet has been busy trying to procure the drugs, one of which is difficult to get in this country so we may have to amend the protocol. Anyway, knowing that my vet couldn’t give me anything more than guesses I asked her how long she thought treatment would take and what she thought it might cost. She told me maybe 8 weeks and Xdollars. The official treatment protocol we received from the consultants is 39 weeks and is looking to cost 2x-3x. Of course.

He will start treatment next week at the hospital. He will stay over one night (if all goes well) and then come home. We have had to make arrangements for the proper disposal of his waste and no one but those authorized will be allowed in his stall.

He will go to the hospital for treatment every time and stay at least one night.

I am told I should keep him in whatever work he is up for throughout this process, which kinda blows my mind. The vets think that some days right after treatment he might not want to be ridden but otherwise they expect him to be good to go, especially when there are 3 week breaks between chemo treatments.

One last thing for now, I use Broadstone equine insurance and he is insured through Hartford. He has been insured through them for major medical and mortality since I purchased him in 2010. I have never filed a claim, until now. New Bolton did a great job providing me with thorough discharge papers, itemized bills, and proof of payment just as a matter of course. I sent them to my insurance company (I have been in light contact with them since he first went to New Bolton) and was expecting to be hearing from them regarding his case and figured filing his claim could be a long process. Instead, a little over a week later I received a check from them covering everything I had submitted, minus of course, my deductible. I was in shock when I opened the mail. Just figured I’d share my positive experience with Broadstone and Hartford :slight_smile:

He went to NB yesterday for his first chemo treatment. He also started prednisone. He is still on the antibiotics. I picked him up today and spent most of the day with him. He is showing no ill effects from the chemo. He seems like his normal self. I am going to see how he feels under saddle tomorrow. Tomorrow is also his 11th Birthday. Here’s to 11 more :wink: He will go back to NB next week for another chemo treatment. Hopefully they all go as well as this first one.

Today he went to New Bolton for his third chemo treatment and he is officially in remission! This is amazing news. He will continue with the remainder of the treatment protocol with the hopes that we will achieve either long term or permanent remission.

His vet at NB is without a doubt the best I have ever encountered. Not only is she obviously smart but she has cared for my horse as if he were her own. If anyone needs the best I would be happy to provide her info via pm.

REMISSION!!! :smiley:

Wonderful! Please keep updating as to how he is doing.

Don’t be afraid to ask about stopping chemo and the steroid earlier than 39 weeks, since he is already in remission. There are a number of protocols. The vet oncologist may decide that a shorter protocol is enough since he is doing well.

I am so glad he is doing well.

That’s great news!!! :smiley: Would you mind giving us a ballpark figure for what the Dx and chemo. cost, just in case any of us ever finds our horse in a like situation? Thanks!

HAPPY DANCE!!!
Congrats! I wish you continued success :smiley:

Im so sorry you are going through this, but so happy you are documenting and posting! Its great to hear your horse is responding so well! Please continue to post about his success in fighting cancer :slight_smile:

Thanks you for posting.
I have a young mare that had an abdominal & thoracic ultrasound last week(and many other diagnostics), and there is a high concern she may have alimentary/intestinal lymphoma.
We don’t have enough information yet, to have an accurate diagnosis. As soon as possible, a repeat scoping to get biopsies will be done.

In the mean time I have been searching the internet and reviewing veterinary publications.
Did your vets discuss other forms of lymphoma? It is my understanding that there is a world of difference in terms of prognosis between the variations…
