How much metastasis does there need to be to cause carcinoid syndrome from midgut carcinoid tumors?

How is the liver? Typically patients do not develop carcinoid syndrome without having tumor metastases in the liver. So tell us about the results of your X-rays and scans of the chest, abdomen and your liver imaging studies. Then we can help you further.

I am experiencing flushing. Is it common for 5HIAA to be mildly elevated? If so, what causes this? If my CT scan and ultrasound of the liver is normal, what is the chances of carcinoid syndrome from a midgut carcinoid tumor?

Distal metastasis. Usually carcinoid tumors cause more syndromal symptoms than just flushing in the late stage. (Diarrhea, weight loss, etc. should occur). 5-HIAA is a metabolite (breakdown product) of serotonin; but also of tryptophan (protein found in foods) - the levels are unreliable for diagnosis but OK as a screening tool. Chromogranin-A = confirmatory test. Use HealthTap Prime to discuss- this is complicated! Read more...

Does carcinoid syndrome/ carcinoid tumors always present with frequent diarrhea and constipation?

No. Sometimes the only symptom is flushing with exercise or sudden increases in blood pressure. Depends on the location of the tumor, how much serotonin it secretes and whether there is any spread into the liver. Constipation is actually unusual. Read more...

In its genealogy, how long does it usually take for carcinoid tumor to metastize to the liver and subsequent progression into carcinoid syndrome? Ty

Slow/unpredictable. Carcinoid tumors are commonly very slow growing tumors. It takes them 10 to 20 years(or longer) to run their course. We can not be exact in predicting when, or if , the carcinoid will spread to the liver. So relax and try not to make any predictions. Most of my patients have no problems for decades of relatively good life despite a tumor nodule or two siting some place in the belly. Read more...
