Anyone with an insulinoma have only therapies instead of surgery?

Posted by briea @briea, Jul 21, 2023

I really recently got diagnosed with malignant insulinoma. About a year ago I collapsed at home and paramedics took me to the hospital (small town then transferred to a bigger city) because of low blood sugar. They took CT scans, said they saw nothing (I've since learned that that is fairly common), but prescribed me diazoxide 2x a day and octreotide shots 3x a day to make my blood sugar at least be high enough to not pass out and sent me home to get an endocrinologist.

My endocrinologist didn't know what was wrong so told me to try to get an appointment at MD Anderson for a 72 hour fast. It took a long time (long story) before they accepted me, which was in May of this year I think.

It went from my endocrinologist sending me for a 72 hour fast to a malignant insulinoma on my pancreas in a few weeks so I am completely overwhelmed.

After a Ga-68 dotatate scan (where my tumors lit up like a Christmas tree) and a biopsy (where they discovered they were malignant with a k-67 of 24) I was referred to an oncologist who I met with once where he told me I had cancer (none of the other doctors told me, I just saw the notes on MyChart, saw, but didn't understand, the scan results, and obviously saw my new doctor was an oncologist).

It was a short meeting and he told me I wasn't a candidate for surgery because I had too many tumors and I couldn't do the long acting lanreotide because it caused my blood sugar to drop significantly before going up again and then gave me paperwork for Everolimus and said that I needed to read over it that weekend and meet with them again and sign some papers and start taking it.

I went home and read about everything as much as possible and it seemed like most people started on other things, like Lutethera , before doing the Everolimus.

I wrote him asking why he chose the treatment he chose (I was completely overwhelmed at the first appointment so didn't really ask many questions), but he was and still is, on vacation so I got a physician assistant who didn't really answer my questions. I met with her a few days ago to go over the Everolimus paperwork and sign stuff and the medicine is currently on its way from a specialty pharmacy. I am to start it as soon as it gets here (along with dexamethasone mouth rinse).

The main reason I agreed to Everolimus was because I wanted to get started on SOMETHING. I have 3 kids (the youngest being 4) and I really want to get started on this journey. I went from reading bedtime stories with my kids to reading cancer articles and scholarly articles with words I can't even pronounce, much less understand what they mean

No one I know, (doctors included) have seen an insulinoma, much less a malignant one, so all this is new to me and I feel completely overwhelmed and don't know what information to read or even how to look things up.

I guess my main question is, has anyone else ever started on Everolimus as a first treatment and, if so, what's your experience? Thank you.

After a lot of tests, scans and different doctors over the course of the last year, I recently got diagnosed with malignant insulinoma in the pancreas that has metastasized to the liver and probably the lymph nodes. It is a well differentiated G3 pancreatic NET insulinoma. The last post here I could find similar to mine (but I am new in trying to navigate this site so I could have missed a lot) was from the beginning of the year so I didn't know if people are still keeping up with that.

I had a Dotatate PET scan in June with biopsies. The main tumor is in the uncinate region of the pancreas with a Ki-67 of 15% but 24% in foci. I have "numerous hyper enhancing observations" all under 2 cm in my liver that my doctor says are too numerable to operate on, but also are "low-volume metastases". I also have "multiple enlarged lymph nodes" that indicate their involvement. I also noticed in my notes it says I have "peritoneal stranding" which he never mentioned at all, but after research seems like that's more bad cancer. I've had lots of blood work, but I have no idea what is important to look at or for because none of those results have been discussed with me and I haven't asked yet in person, but I'm really trying to put it all together.

I got referred to a NET specialist at MD Anderson in Houston a few weeks ago who lightly discussed a few therapies for me, but then strongly suggested chemotherapy and started me on Everolimus that I have currently been on for about 2 weeks. I also take dexamethasone mouthwash.

From my endocrinologist, I also take 3 daily short acting octreotide shots (my doctor was worried about the long acting one because when I take my shots my blood sugar goes down before it goes back up) and 2 daily diazoxide "servings" plus diet to help regulate my blood sugar. It is a constant battle to keep my numbers from going hypoglycemic. I have passed out a few times from low blood sugar, but luckily my family was there to give me an emergency inhaler thing and it's been a few months since that happened last. He also recently put me on Lipitor.

I was overwhelmed with the diagnosis because all the previous doctors (before MD Anderson) acted and said that it probably wasn't an insulinoma, but that if it WAS then it almost definitely was benign because they usually are. Then suddenly I saw a referral to an oncologist on my MyChart so I knew it was bad.

Because of this I probably didn't ask enough questions. I am going back for a follow-up next week and I now have a better idea of what I have and I have questions in a notebook to ask at my visit. I have only seen my NET specialist doctor one time and the rest of my questions (I send online messages because I have to travel fairly far to visit in person) that I asked have been answered by various assistants, nurses and other people on my "team". The visit with my actual doctor was short and seemed more of an introduction. I went in not knowing what was going on, but knowing what an oncologist does, to being overwhelmed with all this information and then the last thing he said was that it was non-curative and that my goal was life prolongation with quality. After reading more, I do realize there is no cure, but it was all new to me then so I admit I was definitely overwhelmed.

But in doing research I saw that many people had different therapies than I do, especially when it comes to getting surgery in removing the main tumor if it's well-differentiated, so I was wondering if anyone else has an insulinoma and what their treatments are/were?

I also found, on another place/site, that many people were disappointed with my SPECIFIC doctor for not being as thorough or aggressive in fighting this disease as they wanted. However, I don't feel like I have enough information or understanding to directly question anything.

I'm wondering if I should get a second opinion on things or if I should send my information to other places? I don't even know how I would go about doing this either.

All this is new to me. I went from not liking to even take Tylenol for headaches and only going to the hospital to have my babies to taking all these medications and scans that, even though I really try and research and read about, are hard for me to understand. But I am determined to be as knowledgeable as possible and become my own advocate for care. I have 3 young children and I definitely want to fight this as aggressively as possible. I keep a journal for questions to ask when I see him now, I'm going to take a friend with me next time so there's someone else there to listen and, if possible, I'm going to record everything. I've also started organizing my notes, test results, and other doctors and places names, different informative sites etc to try and get a better hold of all this new information. I joined some Facebook groups and have started watching some YouTube events with doctors dealing with NETs, and some videos from the Carcinoid Cancer Foundation.

I guess I'm trying to connect with others with similar situations as I have and see if I'm doing the right thing?

Thank you for reading this novel and for offering any help or information or just anything really.

@briea Welcome to the Mayo Clinic Connect. You will find lots of support and people who have been through some of what you are experiencing. For the initial questions about therapies only - I have had surgery twice. After removal or ablation of 11 insulinomas, there were some that were very small and remained in my pancreas. They have now metastasized to my liver. Presently, they are very small and difficult to locate with imaging so medical treatment is my present only option.
For a second opinion, that is always an option you should consider if you don’t feel your first opinion is in your best interest or if you want to truly just have a second opinion. I was referred to Mayo by my Endocrinologist in NC as a second opinion when they could not find other tumors but the hypoglycemia was persistent. I have been going to Mayo every 6 months (on average) since 2017 and every time I have great care and a great experience!
Keep fighting and advocating for yourself! Please let me know if I can assist further.
I am always happy to have communication by phone, if that helps.
Take care!
