High or Fluctuating Chromogranin A Level: What does it mean?

Posted by kaforester3 @kaforester3, Apr 24, 2020

I’m not sure if I’m in the right place or not but I started this conversation here bc my Levels were so high. Has anyone ever had levels that high and what did the doctor say was wrong with you? I’m kind of freaking out bc they are jumping right in and sending me to get a octreotide scan in the next week. Someone please help me because the GI doctor isn’t saying anything.

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

I’m not sure how to do that. I can’t go to another doctor in KS. The other GI doctors stick together and won’t see me. I can however go back up to Mayo in MN I guess. He was a great doctor and I’m sure can figure it out for me.

I am in Australia and waiting to see what the next step for me (lesion liver) but from what i know here if you see a new dr you can request your medical records be sent to your new dr. All you need to do is sign a request to release medical information form

I just got the test done again on June 7th. The test result is 302. However, the test was done through Quest Diagnostic and it says it is in range now. I’m not sure how I feel about the result though because I’m fighting fatigue all the time and I always have pain on my lower right abdomen. I do not have an appendix anymore, so it’s not that. I feel like I cannot get someone to listen to me that something is wrong.
I just did a colonoscopy and an EGD all the biopsies were normal but the Calprotectin level from a stool sample was 82. Should I give the Mayo Clinic a call again or just trust the doctors in KS that seemed to not be looking at all the results.

Hi @kaforester3,

It sounds like you have had a lot of digestive tract problems. Problems with swallowing makes eating so difficult.

Has your doctor ordered the 24-hour urine test (5HIAA) as well as a serotonin blood test? If not, I suggest that you request both tests.

You mentioned having an octreotide scan. There is another test, more precise in finding neuroendocrine tumors called 68Ga DOTATATE Positron Emission Tomography (PET). Here is a link that will give you more information about this test, https://connect.mayoclinic.org/discussion/68ga-dotatate-positron-emission-tomography-pet-now-at-mayo-clinic/. You might ask if a hospital in your area has this type of equipment available.

No I have never had a 68Ga DOTATATE Positron Emission Tomography (PET). I just got the urine test but the results are not back yet.

Could you update when you check again your chromogranin levels, please?

I can surely understand your concern. My CGA was over 1000 and scared me to death. I read too much on the internet and was convinced that cancer and tumors would be my dx. Not so, clean blood results 2nd time around plus urine testing. Now only low grade anemia was of concern. I have had Lyme disease for over 35 yrs and have taken every imaginable medication plus digestive aids in that period. It can be the tums, omeprazole and other anti acid products that can raise the levels. In my case nothing to do but realize I have an infectious disease and do what I can to keep healthy with all the meds I take. Other simple factors can have a bearing like ongoing stress and other personal issues that can raise this odd blood level. Keep positive and go along with the tests to rule out the worst. And realize the best out of this can occur!

Thank you!
It was hard. It was an 'open' MRI and the my husband was holding my hand and was talking to me the whole time.
My trick was to close my eyes before going inside. Nevertheless, I pushed the panic button twice.
I wouldn't recommend the open MRI as it takes much longer than a regular one - almost 1 hour.

That's wonderful that the surgery helped you, @siluka. Being able to eat without a lot of digestive issues is great. Posts, like yours, encourage others who are facing surgery.

I'm wondering if there was a specific eating plan that helped you after the surgery of the ileum? Any do's or don'ts that you might want to pass on to others who are anticipating this type of surgical treatment?

always keep an eye on your iron and b12 levels with blood tests. I do get b12 injections every 3 months and take multivitamins. Also I have here in Australia Sustagen a nutrition supplement which comes in powder for (like milo). I eat most foods now but still cannot tolerate some acid producing foods like tomato. Dietitians put me on a high protein diet. Still i cannot gain much weight but trying. hope this helps.
