Neuroendocrine Tumor - no treatment plan method

Posted by meleve @meleve, Apr 30, 2025

Newly diagnosed with à neuroendocrine tumor Gr1 K167 under 1%. Was removed during a colonoscopy as it presented as a polyp, but the pathology report showed à Neuroendocrine tumour Gr1. It was small 4mm x 6mm and was into the mucosa/submucosal layer. The pathology report didn’t say benign however the Cancer team says they don’t consider this cancer, which conflicts everything I’ve read and researched. The oncologist also said they won’t be doing any further resection or follow up on the tumour even thought my chromogranin a levels are flagged as elevated and I’m still having symptoms. The CT scan didn’t show any evidence of anything else but the oncologist also won’t send for further testing despite having symptoms. Thoughts on no further testing or treatment plans? Or them saying it’s not a cancer?

Hello @mimighosh,

I'm glad that you posted an update about your husband's treatment and that you encouraged others to seek a consultation with a NET specialist. It sounds as if the Lanreotide injections have not resulted in a lot of side effects. Has your husband's medical team suggested any other treatments?

He is on a watch and wait approach right now. There are 3 month scans and blood work, but now that he has been stable for 1 year, they suggest he can do the scans every 4 months.

I also had a grade 1 NET removed from my cecum during colonoscopy. I was referred to a specialist gastroenterologist who did another colonoscopy to make sure it was all removed. He told me that all the tumor was removed and I was as good as new and not to worry. But I continued to have severe diarrhea and weight loss so I asked for a PET scan. No oncologist or any of the GI Dr's would order one, saying it was not needed and insurance would not pay if it wasn't needed. I demanded to have a PET scan and said that I would pay for it myself if they would order it. Finally my oncologist ordered it. The NET in my cecum had metastasized to 2 lymph nodes, my liver and my heart!!! I live in Texas but go to Mayo Clinic in Phoenix...what a wonderful place! It was recommended to me to have a bowel resection but I chose not to have that and have been on Lanreotide injections every 28 days for the last 2 years. It has helped my diarrhea immensely. I've never had any flushing. I have CT scans and MRI's every 6 months at Mayo that show there have been no new tumors, and the ones I have in cecum, lymph nodes, liver and heart are stable with no new growth. I consider myself very lucky, but I know that eventually I may have to have resection and heart surgery. I just live every day with gratefulness and thank God that I'm alive. I also watch what I eat to help keep the diarrhea away. You can find dietary recommendations on netrf.com. I'm sending positive energy your way and praying that you find the answers you're seeking!

Thank you for sharing these parts of your journeys. I have a similar diagnosis to your original (@meleve and @helloitsme) (grade 1 NET removed during routine colonoscopy). The doctor who performed the colonoscopy sought consultation from a local oncologist once the pathology report showed it was a NET with margins involved. That oncologist said I could either have a repeat colonoscopy in 6 months or have the margins removed sooner if I'd like. Everyone locally seems to want to reassure me that it's a best-case scenario (grade 1, very small, "relatively benign"), but I am seeking a consultation from Mayo Clinic in Rochester (I'm in a rural area and I don't get the impression that the oncologist or the surgeon who did the colonoscopy procedure have experience with NETs). My concern is that, while the tumor that they found was relatively benign (not likely to metastasize), I don't know if they can tell if it's the primary site or if this is a metastasis from *another* site.

The plan for my consultation seems to include some blood work and a CT, I'm curious why no PET scan would be ordered. I've been chalking up other symptoms for the past year or so to stress (kid stuff) or peri-menopause (I'm 47), but now I'm a bit worried that I've got NETs elsewhere that are causing these symptoms, and I'm nervous that something will be missed without a PET scan. I don't want to pretend that I know nearly as much as a doctor or sound pushy, so I'm wondering how others might approach this, what to ask, or what others have seen. Thanks!

Hello
I had very similar concerns to you. Also worried I had nets elsewhere and it wasn’t the primary site. However my CT scan and MRI all came back normal and negative for nets, they also won’t order a Dotatate pet scan on me bc the risk is so low. I also live in Canada so our healthcare is a little different. I did seek out advice from 3 separate doctors, a colorectal surgeon, a GI specialist and à neuroendocrine specialist and they all had the same opinions. They did do a 24 hour urine test that did come back normal. I will repeat the colonoscopy in 7 months a year from the original procedure.

Please keep me posted on your findings. I will copy the part from my pathology report as my margins were clear. Here’s what it says:

Depth of invasion : into submission/mucosa and deep resection margins clear/tumor at a distance of 0.3 mm from stromal resection margin

Please keep us posted of your findings and process. Wishing you the best on this journey.

Thank you so much for this helpful information. I will definitely seek a second opinion and post a follow up

Hello @meleve,

I was thinking about you. A few months ago, you posted about seeking a second opinion. Have you scheduled that appointment yet?

I so hope you go to Mayo for a consultation & treatment! All NETs patients need to make sure they’re seeing a NETS Oncologist/Surgeon. “Regular” doctors do not have the expertise needed to treat NETS, learned this the hard way. You definitely have to be your own advocate, never give up on pushing forward for treatment especially if you’re symptomatic. I had multiple CT scans x 2 years & nothing showed up…2 years later I had a PET scan & my NETS had metastasized everywhere. Good luck to you!

Yes I actually saw a net oncologist but I live in Canada so sometimes feel because our healthcare is “free” it’s potentially not as advanced. She did the 24 hour urine test which came back normal and didn’t want to expose me to the Dotatate scan because she said I have nothing to worry about. Her feelings were it was gone and taken care of as a result of the pathology report and my other work ups were normal.
I also saw a gi specialist who reassured me the same as did the colorectal surgeon. So I got 3 opinions I guess. The colorectal surgeon sent me this chart to show where her reasons came from but I’m wondering if this is the same in a different country. Let me see if I can attach the report.

So my net was under 1cm with negative margins in the rectum

Did anyone else ever see this chart from their doctors? I would love to hear everyone’s thoughts on this. As we don’t have a mayo clinic in Canada I wouldn’t be able to be seen. Anyone else have net under 1cm with clear margins that spread?

That chart is for a general oncologist as far as I am concerned. I have a multidisciplinary team at the University of Michigan and I am on Lanreotide I have a out of state home in North Carolina and see a general oncologist for my injections when I am out of town and she was talking to me about my disease and she said she could treat me and showed book with very a similar page. She acted like the treatment I was getting was wrong I was getting captem at the time and she said I should be getting infusions. When I asked her why she said they are stronger. When I discussed it with the net specialist he said infusions don’t work for my type of tumors. So we need specialists! I wouldn’t trust that advice. The chart I saw was part of a binder of pages. I think it’s what general oncologists follow.

Hello, good evening. I hope you're doing well. I'm from Argentina,.

My wife had a NET removed, with clear margins, no infiltrates, lymph nodes, or metastasis, She has checkups every 3 months, and now she's having checkups every 6, but it was larger than 1 cm, it was 1.6 cm, so it matches the guidelines on your chart Generally, there are global recommendations for steps to follow. After that, obviously, each case is different, but there is a global guideline to follow.

PS: I have to admit that I wouldn't be very comfortable without a follow-up, even a minimal one, for example once a year.
