Hope all is well with you
If you get a chance - is this also the case for cats that have had a hypophysectomy? I would assume since tumor is removed, IGF should be normal? Unless of course they couldn't get it all or it regrows?
So many things to speak to here. I guess I want to address the IGF-1 test but I'll refer to Blue's case rather than Eddie's at the moment. As I've said, Blue (Eddie's brother) was the first to have hypophysectomy in February 2018. In August of 2018, he had a check up MRI, which showed a regrowth of the tumour so he went for Fractionated Radiotherapy at the end of 2018. He had an IGF-1 about 8 months following that therapy and it was determined he had a small regrowth of the tumour, for which he then received
one SRT session. He still needed insulin after that and he was getting about 2u/twice daily until he nearly went hypo after which he no longer needs insulin (I check him randomly). Blue's last IGF-1 test was normal range. The issue of regrowth never goes away because they are dealing with
cells and the surgery, no matter how precise, can't always get the whole thing, which is why they go for radiation. It's much more precise.
Eddie is another matter. As you know hypophysectomy in Dec 2020. They could get only 60% of the tumour because it was too close to the hypothalamus to risk any further removal. So, SRT was recommended at the time of surgery as a follow up because the tumour was pretty active even after the 60% was removed. So, he got SRT (3 sessions) only a few months after the surgery, which is unusual but because in Eddie's case the tumour was quite large, an observation that was made to by more than one practitioner. I felt a lot of dread. I do not want Eddie to be anesthetized just for a test, which is why, I guess, I'd go for the IGF-1 if
anything. Make no mistake: even the radiation oncologist told me that research has shown that IGF-1 is not considered as significant a finding after surgery, so I get that. I'm not going to rush out and get any tests done, at all, but I've worked with those people at WSU and I respect them. They saved Blue's life and Eddie's as well since the tumour was so large. I appreciate they respond to a call from me to have a meeting over a year later, even after Eddie has received treatment from another unrelated veterinarian.
All I know is that I'm here, with Eddie and I'm so grateful for the support. I'm taking to heart every bit of advice I'm given and consider it very carefully as it's about Eddie, not me. So, I'm doing my best.
If only we didn't have night time shenanigans, as Melissa calls.
Just did PMPS 311.
Thank you everyone!
