What is a parathyroid adenoma?
The parathyroid glands are four pea-sized glands located in the neck near the thyroid. As part of the endocrine system, they secrete parathyroid hormone (PTH), which regulates calcium levels throughout the body. Tumors can form inside a parathyroid gland and grow very slowly, impacting the body with over-production of PTH, also called hyperparathyroidism. The vast majority of parathyroid tumors are benign (not cancerous) and called “parathyroid adenoma”. In fact, parathyroid cancer has only been diagnosed in a few hundred cases.
Symptoms and risk factors
What are the signs of a parathyroid tumor?
The following symptoms may indicate the presence of a parathyroid tumor and the resulting hyperparathyroidism:
- Lump or nodule in the neck
- Pain in the bones or upper back
- Fractures
- Kidney stones
- Pancreatitis
- Muscle weakness
- Trouble speaking
- Vomiting
- Fatigue
- Weight loss
- Constipation
- Frequent urination
- Extreme thirst
Who is at risk for developing this type of tumor?
Many people with these tumors have no associated risk factors. However, you may be more likely to develop this type of tumor if you have a family history of parathyroid adenomas or you have an inherited condition, such as familial isolated hyperparathyroidism or multiple endocrine neoplasia, types 1 or 2 (MEN1 or MEN2).
Besides genetics, there are no common characteristics that put people at higher risk for developing parathyroid cancer. However, some patients with parathyroid cancer have already been suffering from parathyroid adenomas or hyperplasia.
Screening and prevention
Can you prevent parathyroid adenoma?
Because we don't know what causes these tumors, there is no way to prevent them. However, you may want to talk to your doctor about any potential risk factors and what you can do about them.
Diagnosis
How is a parathyroid tumor diagnosed?
Parathyroid tumors can be difficult to detect, since symptoms are similar to those of simple hyperparathyroidism. At this time, there are no specific tests for these tumors, but an official diagnosis can emerge with the following:
- Blood or urine tests can detect high levels of calcium or PTH in the body
- Imaging tests, such as X-rays, ultrasound, computed tomography (CT) scans, or MRIs may help to locate the tumor and determine its size
After a parathyroid tumor diagnosis, you may need other tests, such as a biopsy. During a biopsy, a small tissue sample will be removed for further analysis under a microscope. This can help your healthcare providers gather important information about your tumor, such as whether it is cancerous and if it has spread.
Types of parathyroid tumors
Treatment
How is parathyroid adenoma treated?
At MedStar Health, your treatment will vary based on your tumor type, location, size, and other factors. Because we take a team approach, several specialists will review your condition and collectively determine the best approach for treating your tumor and any related symptoms. Treatment for parathyroid tumors ranges from active surveillance during which your tumor is monitored over time to surgery and other treatment modalities.
Surgery
Surgery is the primary treatment for parathyroid tumors. Called a parathyroidectomy, the procedure typically involves removing the parathyroid tumor through a small incision in the neck. Sometimes the nearby thyroid gland and lymph nodes may also be removed.
In other instances when the entire tumor cannot be completely removed, your surgeon may remove as much as the tumor as possible, which is called tumor debulking.
Non-surgical parathyroid tumor treatments
Unlike other types of cancer, chemotherapy and radiation are not commonly used to treat this type of cancer. However, when parathyroid cancer has metastasized, additional methods and drugs are necessary to help the body excrete excess calcium. These may include:
- Intravenous saline
- Diuretics
- Bisphosphonates
- Gallium nitrate
- Cinacalcet™
