Frequent question: Is calcitonin a cancer marker?


Is calcitonin a tumor marker?

Plasma levels of calcitonin have been utilized as a tumor marker for medullary carcinoma of the thyroid. Elevated calcitonin levels have been noted with other tumors as well.

What does high calcitonin indicate?

An elevated level of calcitonin means that excess amounts are being produced. Significantly elevated levels of calcitonin (e.g., greater than 20 times the upper limit) are a good indicator of C-cell hyperplasia or medullary thyroid cancer.

What happens when there is too much calcitonin?

What happens if I have too much calcitonin? There does not seem to be any direct deleterious effect on the body as a result of having too much calcitonin. Medullary thyroid cancer is a rare type of cancer that arises from the C-cells in the thyroid gland that secrete calcitonin.

How long does it take to get calcitonin results?

Preparation: Fasting for 10-12 hours required. Test Results: 4-6 days. May take longer based on weather, holiday or lab delays.

What should your calcitonin level be?

A normal value is less than 10 pg/mL. Women and men can have different normal values, with men having higher values. Sometimes, calcitonin in the blood is checked several times after you are given a shot (injection) of a special medicine that stimulates calcitonin production.

Does calcitonin build bone?

The naturally occurring hormone is involved in calcium regulation and bone metabolism. Calcitonin slows bone breakdown and increases bone density in the spine.

What increased calcitonin levels?

The chronic use of omeprazole or omeprazole-like drugs raises calcitonin serum levels after 2 to 4 months of treatment. These drugs may lead to constant stimulation of gastric G-cells and induce gastrin hypersecretion, ultimately leading to high serum levels of calcitonin.

What does calcitonin do in the kidneys?

By preventing the breakdown of bone, calcitonin lessens the amount of calcium in the blood. The hormone also seems to decrease the amount of calcium the kidneys can re-absorb, lowering levels further. Secretion of this hormone is controlled directly by the blood’s calcium levels.

What are the side effects of calcitonin?

Calcitonin salmon may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

  • runny nose.
  • nosebleed.
  • sinus pain.
  • nose symptoms such as crusts, dryness, redness, or swelling.
  • back pain.
  • joint pain.
  • upset stomach.
  • flushing (feeling of warmth)

Is calcitonin good or bad?

Calcitonin regulates blood calcium levels and possesses certain clinically useful anti-fracture properties. Specifically, it reduces vertebral fractures in postmenopausal osteoporotic women significantly compared to a placebo.

What triggers calcitonin release?

Calcitonin secretion is stimulated by increases in the serum calcium concentration and calcitonin protects against the development of hypercalcemia. Calcitonin is also stimulated by gastrointestinal hormones such as gastrin.

How long can a person live with hypercalcemia?

Unfortunately, cancer-related hypercalcemia has a poor prognosis, as it is most often associated with disseminated disease. Eighty percent of patients will die within a year, and there is a median survival of 3 to 4 months.
