What is Octreoscan used for?

An octreotide scan is used to detect and monitor treatment of neuroendocrine tumours, which arise from cells that produce hormones that are carried in the bloodstream. Many of these tumours are benign (non-cancerous), but some are malignant and can spread around the body.

What does an Octreoscan show?

The radioactive octreotide attaches to tumor cells that have receptors for somatostatin. A radiation-measuring device detects the radioactive octreotide, and makes pictures showing where the tumor cells are in the body. Also called somatostatin receptor scintigraphy and SRS.

How long does an Octreoscan take?

This scan takes about 20 minutes. These images will be shown to the radiologist and the radiologist will determine if another set of images is needed on this day. If needed, the technologist will take another set of images called a SPECT/CT.

Is Octreoscan a PET scan?

Background: Clinicians may order Octreoscan or positron emission tomography (PET) scan for staging patients with neuroendocrine tumors (NETs).

When is an octreotide scan done?

This test is used to look for neuroendocrine cells throughout the body. This scan may be used to see the primary neuroendocrine tumor during initial (diagnostic) testing. It may also be done at other times to check for tumor cells that have spread (metastasized).

Does octreotide shrink tumors?

Octreotide is helpful in treating the symptoms of carcinoid syndrome. Sometimes octreotide can temporarily shrink carcinoid tumors, but it does not cure them. The original version of octreotide (Sandostatin®) is injected under the skin (subcutaneously) at least twice daily.

What is pancreatic neuroendocrine tumor?

Pancreatic neuroendocrine tumors (NETs), or islet cell tumors, are a type of cancer that starts in the pancreas. (Cancer starts when cells in the body begin to grow out of control. To learn more about how cancers start and spread, see What Is Cancer?) Pancreatic NETs are a less common type of pancreatic cancer.

Does CT scan show carcinoid tumors?

A CT scan is most often used to look at the chest and/or belly (abdomen) to see if GI neuroendocrine (carcinoid) tumors have spread to nearby lymph nodes or other organs such as the liver. It can also be used to guide a biopsy needle into an area of concern..

How much does an Octreoscan cost?

On MDsave, the cost of an Octreotide Scan (Octreoscan) ranges from $1,439 to $3,564. Those on high deductible health plans or without insurance can save when they buy their procedure upfront through MDsave.

What is the difference between a PET scan and an octreotide scan?

Conclusions Ga PET/CT is more accurate for staging and superior to Octreoscan SPECT in the detection of overall number of lesions in the body as well as organs and bones. Ga PET/CT also allows for calculation of standardized uptake value, has less whole body radiation, and is performed in less time versus Octreoscan.

How is Octreoscan done?

To detect these tumours, a small amount of harmless medication, a radiopharmaceutical (see InsideRadiology: Nuclear Medicine), is injected into a vein in the arm, followed by a whole-body scan to take pictures or images. The same images are also taken the next day, but no further injection is given on the second visit.

What is a NM Octreoscan?

A Nuclear Medicine Octreoscan exam is used to detect and localize neuroendocrine tumors. Images will be 24 hours after the injection. There is also a possibility of a second set of images at 48 hours after the injection. This will be determined after the images are taken at 24 hours.

Where is neuroendocrine tumor?

Neuroendocrine tumors are rare and can occur anywhere in the body. Most neuroendocrine tumors occur in the lungs, appendix, small intestine, rectum and pancreas.

Can stress cause neuroendocrine tumors?

The neuroendocrine mechanisms of chronic stress. Chronic stress produces stress hormones during the activation of the neuroendocrine system (hypothalamus-pituitary-adrenal axis) and the sympathetic nervous system, which can promote tumor development and regulate the tumor microenvironment.

What is the most common endocrine tumor?

About the Endocrine System

  • Thyroid cancer is the most common type of endocrine cancer, diagnosed in about 64,000 people each year. …
  • Endocrine cancer can also affect the pancreas, which is an organ in the belly.
  • Neuroendocrine tumors are endocrine tumors that also affect the nervous system.

Can a neuroendocrine tumor be cured?

Many neuroendocrine tumors can be successfully treated with surgery and chemotherapy, especially if the tumor is localized and has not spread to the lymph nodes or other organs in the body.

What foods should be avoided with neuroendocrine tumors?

Limit or avoid stimulants such as alcohol and caffeine.

  • Include binding foods: applesauce, bananas, tapioca, barley, oats, white rice, noodles, peanut butter, baked potato without the skin.
  • Avoid foods that are natural laxatives, such as prunes, prune juice, rhubarb, and papaya.

Are neuroendocrine tumors genetic?

Although neuroendocrine tumors are in some cases associated with inherited genetic syndromes, such syndromes are rare. The majority of neuroendocrine tumors are thought to be sporadic. We performed a genome-wide association study (GWAS) to identify potential genetic risk factors for sporadic neuroendocrine tumors.

How is neuroendocrine tumors detected?

You might undergo imaging tests, such as ultrasound, CT and MRI , to create pictures of your tumor. For neuroendocrine tumors, pictures are sometimes created using positron emission tomography (PET) with a radioactive tracer that’s injected into a vein. Procedures to remove a sample of cells for testing (biopsy).

What causes a neuroendocrine tumor?

Inherited gene mutations

Multiple Endocrine Neoplasia Type 1 (MEN1) syndrome: Most inherited cases of PNETs are due to changes in the MEN1 gene. This syndrome can cause cancer in the pancreas, parathyroid glands, and pituitary glands. These tumors usually happen at younger ages and tend to be non-functioning.

Do neuroendocrine tumors have to be removed?

Pancreatic NETs that have not spread outside the pancreas should be completely removed, if possible, because these tumors are more likely to be cured with surgery.
