Hi -- I am in Cincinnati. Our Cat, Fonzie, had SRT in Cincinnati at the Med Vet this past Oct, 2024. We began seeing results in Dec 2024, where he was on 6 units twice a day and we began dropping steadily. Now, Feb 20, he is at 1.5 units AM and 1 Unit PM. We are still trying to find his best dose as we had a low glycemic event last Thursday where he dropped to 65 within 2 hours of Insulin. He is on Lantus. But, we are encouraged by the decreased need for insulin -- just still trying to find his correct dose. It has been a journey -- frustrating at times, but I know we made the right decision to treat with SRT. Med Vet did a great job w/ the SRT. I was a complete "helicopter parent" obsessively calling the IM specialist and Oncologist, but, the treatment seems to be working. It was scary putting him under anesthesia for 3 consecutive days in a row, but, they worked with me on the amount of anesthesia and were in constant contact. Ultimately, they did a great job and have a good team. Fonzie is 14 and otherwise in good health other than IBS and slight pancreatitis and the Acromegaly. We are not planning on doing a follow up CT scan as that was very traumatic for him and we don't want to put him through that again. However, I am planning on re-testing for the HG-1 hormone blood test to see if it has changed since the SRT. We are doing that next week. Let me know if you have any questions, happy to share.Does anyone have experience with SRT in Ohio?
MedVet Columbus or OSU?

Thank you for the info. It's all very overwhelming.
A couple of questions:
Did Fonzie stay in the hospital or did you do outpatient?
How was Fonzie feeling/acting in the days following the treatment?
I will prbly have more questions. I hope it's okay to reach out as they come to me.
Thank you!
Neko was not treated in Ohio, but location shouldn't impact how it's done. I stayed in a hotel and took Neko in each day and she stayed with me overnight. Only cats with some risky medical issues (like heart) that needed extra monitoring stayed overnight at CSU. Timing for visits was similar to Fonzie's. After the first day, which was the long one with CT scan, Neko was scared and hid under furniture for a couple hours. But came out at dinner time and settled down. She was fine the rest of the days. Some smaller percentage of cats can get fog or possible headache from the procedure. I was given a prescription for prednisolone as an anti-inflammatory to be given for 5 days if needed. We didn't need it but have heard of one that did. We have had a couple cats here have irritation of the throat due to the intubation. Soft tissue growth, if they have it there, can make the throat more narrow and I've see people recommend kitten size intubation tubes because of that.A couple of questions:

Second time with SRT was more scary. In spite of the all clear from the cardio vet and an echocardiogram done two weeks before hand, she had a heart block during the CT scan. The radiation oncologist consulted with a cardiologist (thankfully vet teaching hospital had all the specialists needed to consult), and the team decided she'd get just one larger dose instead of 3 smaller doses as done the first time. But we gave her a couple day break first. They consulted with NCSU who had done quite a few of the single dose procedures - turns out some of those team were CSU grads.

Neko was the first retreated cat mentioned in the paper.

Thanks for sharing your story about Fonzie.
Save your money on retesting the IGF-1 values. That’s what I was told by Colorado State University who did a lot of the early research on SRT for acros, including retesting IGF-1. The value doesn’t indicate anything about the size of the tumour, and can even go up after SRT. Which I have seen with the odd person who did retest, and was disappointed by the result.

Well, Monday is Day 1 of Buster's SRT at OSU in Columbus, OH. Buster will be staying in the hospital for the 3 day treatment. I am a nervous wreck.
Please keep him in your thoughts...
@Madm4444 sending strength and best possible outcome for Buster! I know you are nervous and want to make the best decisions for him. You are doing that! Lots of hugs to Buster!!
Good luck on Monday!
I would find out when you can visit. Also find out when you can call or ask to have a resident or the vet (someone who actually knows what's going on with Buster) call to give you an update.
Bring along an article of clothing that smells like you. (In other words, wear a T-shirt that you can make sure is smelly and bring it along.) It may help to keep Buster calm.
Did they say why he's staying in the hospital instead of staying with your overnight? Some cats don't eat well in the hospital, though generally not so much an issue with acros. Make sure they've got his favourite food. Also ask if you can come in and give his shots - that's what I did when Neko had to stay in ER for a few days. Not sure I'd trust the clinic to get his shot done on time and make sure he's eating. One morning I came in and Neko was 59 on the AT.Definitely a skip that morning!
Given that Buster's been seeing some loverly greens, I'd take his dose down, at least one unit, for the duration of his SRT. Not sure I'd trust the clinic to get his shot done on time and make sure he's eating. He should be getting a reduced dose in the mornings, but ....
I'm sure the SRT part will go well, once this is all over you will be so happy you had it done.

Gosh, I'm a bit late to the conversation so hope all went well. Both Eddie and Blue had SRT at different times and while Blue did better than Eddie while staying overnight, both of them came out ok. All my best thoughts for Buster and you!@Madm4444 sending strength and best possible outcome for Buster! I know you are nervous and want to make the best decisions for him. You are doing that!

I hadn't realized his heart issues were anything more than a murmur. Have you had an echocardiogram done on him? FWIW, Neko had a heart block and they had a hard time getting her out of anaesthesia for the CT scan for her second round of SRT. She still came back to the hotel with me.

Good luck tomorrow. I’ll be thinking of you.
Every Cat is very different. Neko earned her first reduction on the road trip home, most take a little longer. I've seen some as long as 3 months. Keep posting and we can help you through this next stage of the adventure.Now, we wait...

Good luck with the Cisapride. I hope he will not need it after five days. In human patients, it was banned due to causing heart arrhythmia — an effect that has not been documented in veterinary patients. The Cisapride helps GI motility and the MiraLax softens the stool, so they work on different aspects of constipation (so hopefully no double whammy there for Buster!)
I noticed the 14 units this morning. I think it was brave of you to shoot 14 units with a 128 AMPS. I know you are eager to get everything back on track. However, we can see now (with hindsight) that it was the end of his long string of blues continued over from last night. He went yellow… and then? I am really hoping he won’t go into pink or red. I will wait for you to update his SS when you get a chance. Did you have to install the new Libre sensor yourselves?
You & I didn't get a chance to connect this morning about his dose. After 15u last night dropped him so fast & 8u didn't do much in the hospital, I thought we had an opportunity to do less.
What dose would you have suggested with the 128 AMPS?[/ I thought you did fine to shoot the 14 units. I only meant that not a lot of people would have. I am glad you continued with 14 today. We need to see how it goes for at least 6 cycles (unless he surprises by earning a reduction.)
I had a feeling! I didn’t think your SS was updated when I looked but I had a feeling. I think you better reduce. Reduce by ten percent at least 1.5 units. If he’s low at PMPS you may need to consider reducing even more.
A green one.Given his numbers, what do you consider a low PMPS?
