Pancreatic neuroendocrine insulinoma

Do any of You had 11C-5-hydroxy-tryptophan PETCT or know if Your facilities offer it. What was done for Your hypoglycemia and what helped. Did you have functioning or non functioning insulinoma? How fast were the liver mets multiplying/enlarging? Did anyone have 72hr fast test
Thank You,
Margaret

Hello @margaret12

You are asking some good questions. I would like to invite some of our members like @ahtaylor @links and @lastround to share their experiences with you.

What type of scans have you had so far? What is your medical team currently suggesting to control the hypoglycemia?

I'm seeing oncologist tomorrow, no treatment, Im being mostly ignored even though MRI shows progression of illness

Welcome and thanks, Margaret for the questions! To respond to your questions:

My PET/CTs have been with dotate. I have not had one with the contrast you mentioned.

I don't have confirmed liver mets, the areas on my liver are being monitored for possible metastasis. However, for the most part they have been stable to very slow enlargement over time.

I utilize glucose tablets primarily to bring my blood sugar back up. Occasionally, I will also need OJ in addition to the glucose tablets. My hypoglycemia mostly occurs after meals (within 30-45 minutes) and with exercise. Only occasionally do I have fasting hypoglycemia. The presentation made my diagnosis a bit more challenging as it is not a common presentation of insulinomas.

I have done the 72 hour fast a couple of times for diagnostic purposes and then some modified fasts as well as mixed meal tests for evaluation of the behavior of the tumors after they were confirmed to be present. The first one I had that was diagnostic, my blood sugar dropped into the 40s at about 40 hours. Do you have particular questions about the 72 hour fast? My confirmed insulinomas have all been functional.

Have you ever done a Calcium Stimulation test? Are you a current Mayo patient or considering care at Mayo? Looking foward to hearing more from you and thanks again for sending the message! Take care!

I've had MRI'S and CT scans (5) with contrasting.
Had my latest Friday my 12th chemo was today .
Tumors are shrinking, but still have some fairly large ones on my liver, they never talk about my Pancreas, not the biggest problem.
If there having trouble controlling your suger (glucose) it's your liver. I spent the month of June in the hospital until I started chemo. My suger would drop into the 40's and got to the point where I couldn't get the sugar up to normal, above 70.
Now I'm at 90 to 100 and steady.
Chemo is no fun but it worked for me to shrink the tumors. Is I said in the past I have over a dozen. I asked about Target Radiation but Dr said no.

Links,
Sounds like you have what I have.
Mine started in my Pancreas and is in my liver now.
Got diagnosed in May of 2022.
Like I've said I'm on my third hospital. The first 2 fiddled around for months with my glucose numbers. With no results. I used to say I was on the 12 year boy diet, candy's, cakes, etc. Just kidding, But that didn't work after a few months.
Hospital number 2 told me no to worry, liver failure is painless, the next day I got a call to see if I wanted to participate in an end of life study. I told them I'm no buy a shovel yet and NO .
Next call was to hospital number 3 that put me on chemo that week. Actually felt great for about a month, that as the treatment continued, no so much.
I received treatment every 2 weeks and came home with a bag of chemo that runs for 46 hours. I have a Port so we disconnect at home and bring it in the next time we go in.
I just finished my 12th round, 6 months.
If you're sugers are hard to control, it's in your liver. Don't wait. I think I was diagnosed to late.

Hello
I have had about 16 rounds of chemo..happening every two weeks.
The primary tumor is pancreatic and I have lesions on the liver. My scans thus far have shown
shrinkage so the plan is to continue on the chemo...Foflox..
Yes the eating is hard....but having the insusolinoma I have to try to maintain the sugars..so I have to force it..soups are good,easy to eat..but sometimes not enough protein.I do make some shakes,but that doesnt quite help the sugars. Yes the neuropathy is hard..but I dont want them to change the chemo so I try to just deal with it. As long as the chemo is working they will continue it. All they tell me is that there are other things but we are not there yet.
I do get quite nauseous especially after the chemo...so dealing with that and trying to keep my sugars up is quite challenging.Orignally they said no surgery....but I am hoping there are other procedures they might be able to do. I know some people who have had ablations and PRTT procedureds to help kill the lesions. Im hoping they will have a plan..for now this is it.Please dont hesitate to reach out with questions...open to hear about your journey..ps also at Dana Farber!
My best
Marlene

Message to all,
if your having trouble with your suger, glucose, corn starch helps to regulate your levels.
I mixed it with chocolate pudding, made it edible, really couldn't taste it.
I imagine any flavor will work.

Hats off to links for 16 rounds of chemo.
I'm taking a break at 12, I'm starving, I can't eat
