Pancreatic neuroendocrine insulinoma

Posted by links @links, Jan 19, 2023

Looking to connect with anyone who has an insulinoma. My tumor presents in the pancrease. I currently have chemotherapy bi weekly since July 2022. This is a rare combination and have struggled with regulating my sugars and hoping to meet someone else with a similar diagnosis.

Interested in more discussions like this? Go to the Neuroendocrine Tumors (NETs) Support Group.

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

I do use cornstarch. I mix it with ginger tea
I also eat an extend bar before bed to try and hold my sugars thru the night

To all,
I finish my 12th chemo yesterday I think the dr wanted to keep going but I need a break, I’m week and hungry. Going back for scans in 2 months.
I’ve been asked what I’ve been taking.
I take a 28 day shot in my butt called Octreotide.
Chemo days it Oxaliplatin, Levcovorin, dexamethasone [steroid], fluorouracil.
Afinitor [everolimus] is a daily pill I took at first to control my suger. With in a few weeks after starting chemo I stopped taking it. Also, had to fight with the insurance company for that one, the pills are about $6,000 a month but the hospital got it approved.
Happy to here some of you are here after 5 years. When I look on line the studies I fine say up to 10 years but don’t mention how old the subjects are.
I’ve asked my doctor about targeted radiation and I always get a flat no. But if they can kill a few big tumors on the surface, why not? I know they will not be able to get them all, but it seems they grow like weeds. Can they be zapped when the surface? I don’t know, just a guy trying to stay above ground.

Hello Bob and welcome to the NETs discussion on Mayo Connect. This is a discussion group that deals specifically with insulinoma and I thought you might find it helpful to meet the members here who also have this type of NET. I understand from your previous post that your glucose is now under control as the chemo has shrunk the tumors. That must be rewarding to have some relief.

You mentioned that you have been having chemotherapy. If you are comfortable doing so, what type of chemo are you having? Have you had many side effects?

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 appreciate Your follow up. Unfortunately I was disregarded by the oncologist, the only thing that was offered are iron infusions and that is despite elevated 5 HIAA and glucagon and Pancreastatin in the past. The one said he would never order Pancreastatin. I said, they were done and they are elevated, shouldn't we do something about it? I also have hypoglycemia 30min -1 hour after eating. All my fasting glucose is fine but I wasn't able to fast for more then 16 hrs. I have asked continuously for 72hr fast, including the oncologist today and it was denied. My liver has close if not over 20 tumors that I being disregarded as cysts. Bile ducts in and out of liver are enlarging and beyond EUS nothing was done. No Neuroendocrine clinic will take me without liver biopsy and doctors refuse to do one. I have increasing GI issues and exhaustion beyond the point of managing this illness. Who ordered 72hr fast for You? Was it done at the hospital? Thank you,

For both of the 72 hour fasts, the endocrinologist ordered. The first was
done in the hospital in NC. The second was done at Mayo and was started in
the clinic with conversion to hospital if not hypoglycemic by close of
clinic.
Calcium stimulation was another very helpful test- it will confirm presence
or absence of insulinoma and localize to the region of the pancreas as well
as can be done with the liver. The calcium is used to stimulate the tumors
to produce insulin and results are found in the insulin levels that are
drawn every 20 seconds after injection. This is all done through femoral
arterial and venous lines. This procedure was done at Mayo.
Hope this is helpful. I am happy to continue to answer questions as I truly
understand how challenging this can all be!
Take care.

What hospital are you in?

Administration,
Can these posts get a little more organized? Getting hard to follow conversations posts are all over the place

Bob,
To provide some additional information. . . I have had 2 surgeries - a modified whipple in NC in 2015 and a distal pancreatectomy/splenectomy in 2017 at Mayo - in those two surgeries, there were 11 total tumors that were either removed or ablated. After the second surgery in 2017, hypoglycemia persisted, and it was discovered through a Calcium Stimulation test that there was at least one if not more tumors still in the pancreas. Up until 11/2022, the tumor(s) could not be seen on imaging due to small size. There are 2 very small areas (5mm or smaller) now visible on CT that are possible insulinomas in the pancreas, as well as a couple of areas on the liver that are indeterminate but possible insulinomas. Due to their size, location and the extensive previous surgeries, the pancreatic tumors are currently deemed inoperable. Chemo and radiation have not been part of the plan of care due to the size of the tumors and the inability to monitor if the tumors are shrinking. Thankfully, the desensitization to the octreotide is helping keep significant allergic reactions from occurring and the medication is quite effective in creating a significant decrease in hypoglycemia episodes. I continue to go to Mayo clinic every 6 months and the care is excellent. I feel in very good hands in Rochester. Wishing you the best in your continued journey. Hope to hear from you soon. Take care!

Thanks Taylor, that is interesting.
Glad to hear that the medication is working. I just finished my 12th round of chemo, so maintaining programs are next

Hello @lastround.

In order to follow conversations easier, I suggest two things:

When you are responding to a post, always start the post with the individual's screen name (@name) that they use (as I did when I started this post to you).

Also, when you respond to a post, click on "Reply" that is another way the response gets directed to the person who are responding to.

I hope this helps all in this discussion group including, @margaret12 and @links. This is probably something you have all used, but it is a good reminder.
