Diagnosing Wermer's Syndrome (Multiple Endocrine Neoplasia, Type 1)

Overview

Multiple endocrine neoplasia type 1 (MEN1), also called Wermer’s Syndrome, is a rare genetic disorder that can cause tumors to grow in different hormone-producing glands and other tissues. These glands are found in different parts of the body and make hormones that help control important functions like growth, digestion, and sexual health.

When it comes to diagnosing MEN1, different specialists may be involved in your care:

• Endocrinologist: A specialist in hormone-related disorders who plays an important in diagnosing and treating MEN1.
• Genetic counselor: A healthcare professional who helps people understand genetic testing and what the results may mean for them and their family. They provide advice about the risks and family patterns of genetic conditions.
• Radiologist: A specialist who looks at imaging tests like X-rays and MRIs to help diagnose MEN1.
• Surgeon: If surgery is needed to remove tumors related to MEN1, a surgeon will perform this procedure.

To diagnose MEN1, several exams, tests, and procedures are usually done. These help confirm the diagnosis and identify the type (specific kind of tumor), severity (how serious it is and how quickly its likely to grow), or stage (how far it has spread). Here's what you can expect:

• Physical exam: This exam helps the healthcare provider gather information to see if there may be signs of MEN1 and decide if further testing is needed. Signs may include:
  • Pain or tenderness in certain areas
  • Swelling, especially in the neck (due to possible thyroid or parathyroid tumors)
  • Signs of kidney stones, such as back or side pain
  • Any lumps or masses in the abdomen, which could suggest growths in the pancreas or other glands
• Blood tests: These can help find hormone levels that may be too high, such as calcium, parathyroid hormone (PTH), and other hormones related to the pituitary or adrenal glands. Higher than normal levels can be a sign of MEN1.
• Genetic testing: Genetic tests check for changes in the MEN1 gene. This testing looks at chromosomes, which are structures inside cells that carry DNA. Finding changes in the MEN1 gene can confirm the diagnosis and identify if a person may develop MEN1 or pass it on to their children
• Imaging tests: Imaging tests like X-rays or MRIs may be recommended to get detailed images of the body. These scans can help find any unusual growths or tumors in the endocrine glands commonly affected by MEN1, such as the parathyroid, pituitary, or pancreas.
• Clinical Procedures: Additional tests may be recommended based on symptoms. These might include:
  • Bone density scan: To check bone health, as high calcium levels can lead to bone thinning
  • Abdominal ultrasound: To check for tumors in the pancreas or adrenal glands
  • Blood pressure checks: To find high blood pressure, which can result from adrenal gland tumors
  • Vision tests: In cases where pituitary tumors may affect vision by pressing on nearby eye nerves

To determine the type, severity, or stage of MEN1, additional exams, tests, or procedures may be done:

• Further imaging scans: Additional imaging scans, like CTor PET scans may be done to see how far tumors related to MEN1 have spread and learn more about their size and location. These scans can also show if the tumors are affecting nearby areas.
• Biopsy: This test involves taking a small tissue sample from a tumor to look at under a microscope. It helps confirm if the tumor is cancerous, identifies specific types related to MEN1, and provides information on how likely it is to grow or spread.

It's important to talk about these exams and test with your healthcare provider. They will guide you through the diagnostic process based on your symptoms and medical history. Remember to ask your healthcare team if genetic testing is right for you and if any additional procedures are needed to determine the type, severity, or stage of MEN1.
