Parathyroid Cancers

What is Parathyroid?

  • Parathyroid carcinoma is a rare condition in which malignant (cancer) cells grow in parathyroid gland tissues.
  • Certain hereditary abnormalities might raise your chances of getting parathyroid cancer.
  • Parathyroid cancer symptoms include fatigue, weakness, and a lump in the neck.
  • Parathyroid carcinoma is diagnosed with tests that evaluate the neck and blood.
  • Certain factors influence prognosis (the likelihood of recovery) and treatment options.

The parathyroid glands are four pea-sized structures located near the thyroid gland in the neck. Parathyroid hormone is produced by the parathyroid glands (PTH or parathormone). PTH aids the body’s usage and storage of calcium, allowing calcium levels in the blood to remain normal.

Hyperparathyroidism occurs when the parathyroid gland becomes hyperactive and produces an excessive amount of PTH. When a benign tumor (noncancer) called an adenoma grows on one of the parathyroid glands, it causes it to expand and become hyperactive. Hyperparathyroidism can occasionally be caused by parathyroid carcinoma; however, this is extremely rare.

Extra PTH results in:

Calcium from the bones is released into the bloodstream.

The intestines absorb more calcium from our meals.

This is known as hypercalcemia (too much calcium in the blood).

Hypercalcemia produced by hyperparathyroidism is more dangerous and life-threatening than parathyroid cancer, and treating hypercalcemia is just as critical as treating cancer.

Certain inherited defects may increase your risk of developing parathyroid cancer.

A risk factor is something that increases the chances of getting a disease. The following infrequent inherited (passed down from father to child) diseases are risk factors for parathyroid cancer:

Hyperparathyroidism in an isolated family (FIHP).

Multiple endocrine neoplasia type 1 syndrome (MEN1).

Radiation therapy may increase the chances of developing a parathyroid adenoma.

Parathyroid cancer symptoms include fatigue, weakness, and a lump in the neck.

The hypercalcemia that develops causes the majority of parathyroid cancer signs and symptoms. The following are the signs and symptoms of hypercalcemia:

  • I’m quite exhausted.
  • Vomiting and nausea.
  • Appetite loss.
  • Weight loss for no discernible cause.
  • Being thirstier than normal.
  • I’m urinating a lot more than normal.
  • Having difficulty thinking coherently.

The following are other indications and symptoms of parathyroid cancer:

  • Pain that persists in the belly, side, or back.
  • Bone discomfort.
  • A fractured bone.
  • A lump in the throat.
  • Hoarseness is one example of a voice change.
  • Having difficulty swallowing.
  • Other illnesses may exhibit the same symptoms as parathyroid carcinoma.

If you have any of these symptoms, see your oncology doctor, Dr. Suyash Agrawal

Parathyroid carcinoma is diagnosed with tests that evaluate the neck and blood.

After blood tests confirm hyperparathyroidism, imaging studies may be performed to determine which of the parathyroid glands is hyperactive. When the parathyroid glands are difficult to locate, imaging tests are used to pinpoint their precise location.

Because the cells of a benign parathyroid adenoma and a malignant parathyroid cancer look similar, diagnosing parathyroid cancer can be difficult. The symptoms of the patient, blood levels of calcium and parathyroid hormone, and tumor features are all utilized to obtain a diagnosis.

The following tests and procedures are possible:

  • Physical exam and health history: An examination of the body to examine general indicators of health, including the appearance of lumps or anything else that appears strange. A history of the patient’s health habits, as well as previous diseases and treatments, will be collected.
  • Blood chemistry tests: A method in which a blood sample is examined to determine the levels of specific compounds produced in the blood by the body’s organs and tissues. A chemical in an unusual (higher or lower than normal) concentration might be a symptom of sickness. A blood sample is tested for calcium levels to identify parathyroid carcinoma.
  • A parathyroid hormone test is a process that measures the quantity of parathyroid hormone secreted into the blood by the parathyroid glands. A higher-than-normal level of parathyroid hormone can indicate illness.
  • Sestamibi scan: A radionuclide scan that is used to detect an overactive parathyroid gland. A very little quantity of technetium 99, a radioactive material, is injected into a vein and passes via the bloodstream to the parathyroid gland. The radioactive material will gather in the overactive gland and shine brightly on a radioactivity-detecting camera.
  • CT scan (CAT scan): A method that produces a series of detailed images of locations inside the body from various angles. A computer coupled with an x-ray machine creates the images. To make the organs or tissues more visible, a dye may be injected into a vein or ingested. This is also known as computed tomography, computerized tomography, or computerized axial tomography.
  • A SPECT (single photon emission computed tomography) scan is used to detect malignant tumor cells in the neck. A radioactive material is injected into a vein or breathed via the nose in modest amounts. A camera spins around the body, photographing the neck as the drug flows through the blood. The images are used by a computer to create a three-dimensional (3-D) image of the neck. Increased blood flow and activity will occur in places where cancer cells are developing. 
  • Ultrasound examination: A method in which high-energy sound waves (ultrasound) bounce off inside tissues or organs, creating echoes. The echoes combine to generate an image of bodily tissues known as a sonogram.
  • Angiogram: A process that examines blood arteries and blood flow. In the blood vessel, a contrast dye is injected. X-rays are obtained while the contrast dye passes along the blood artery to detect if there are any obstructions.
  • Venous sampling is a process in which a sample of blood is drawn from a particular vein and analyzed to determine the number of certain compounds produced in the blood by adjacent organs and tissues. If imaging studies do not reveal which parathyroid gland is hyperactive, blood samples from veins near each parathyroid gland may be collected to determine which one is producing too much PTH.

Certain factors influence prognosis (the likelihood of recovery) and treatment options.

The following factors influence the prognosis and treatment options:

  • Is it possible to manage the calcium level in the blood?
  • Cancer’s progression.
  • Whether or not the tumor and its capsule can be entirely removed after surgery.
  • The general health of the patient.

Parathyroid Cancer Stages

Following a diagnosis of parathyroid cancer, tests are performed to determine whether cancer cells have spread to other regions of the body.

  • The cancer spreads in three ways throughout the body.
  • Cancer can spread from its original site to other sections of the body.
  • Thyroid cancer can be classified as either localized or metastatic.
  • After treatment, parathyroid carcinoma might return (reappear).

Following a diagnosis of parathyroid cancer, tests are performed to determine whether cancer cells have spread to other regions of the body.

Staging refers to the process of determining if cancer has spread to other places in the body. For parathyroid carcinoma, there is no defined staging scheme. The imaging tests listed below may be performed to determine whether cancer has progressed to other regions of the body, such as the lungs, liver, bone, heart, pancreas, or lymph nodes:

CT scan (CAT scan): A method that produces a series of detailed images of locations inside the body from various angles. A computer coupled with an x-ray machine creates the images. To make the organs or tissues more visible, a dye may be injected into a vein or ingested. This is also known as computed tomography, computerized tomography, or computerized axial tomography.

MRI (magnetic resonance imaging): A process that takes a series of detailed photographs of locations within the body using a magnet, radio waves, and a computer. This method is also known as nuclear magnetic resonance imaging (NMRI).

The cancer spreads in three ways throughout the body.

Cancer can spread through tissue, the lymph system, and the blood:

  • The cancer spreads from where it started into neighboring places.
  • The lymphatic system. The malignancy spreads from the site of origin by infiltrating the lymphatic system. Cancer spreads to other regions of the body via lymph veins.
  • The malignancy spreads from the site of origin by entering the bloodstream. Cancer spreads to other regions of the body via the blood arteries.

Thyroid cancer can be classified as either localized or metastatic.

  • Localized parathyroid cancer develops in the parathyroid gland and may spread to adjacent tissues.
  • The lungs, liver, bone, sac surrounding the heart, pancreas, or lymph nodes have all been affected by metastatic parathyroid carcinoma.

After treatment, parathyroid carcinoma might return (reappear).

Cancer may reappear in the tissues or lymph nodes of the neck or elsewhere in the body. A recurrence occurs in more than half of patients. Parathyroid carcinoma often returns 2 to 5 years after the initial operation, although it can return up to 20 years later. It generally returns in the neck tissues or lymph nodes. High blood calcium levels following therapy might be the earliest symptom of recurrence.

Treatment of Metastatic Thyroid Cancer

See the Treatment Option Overview section for details on the therapies listed below.

Treatment for metastatic parathyroid carcinoma may involve the following:

  • Surgery (metastasectomy) to remove cancer from the sites where it has spread.
  • Surgery is followed by radiation treatment.
  • Radiation treatment.
  • Supportive treatment for hypercalcemia (too much calcium in the blood).

Recurrent Parathyroid Cancer Treatment

See the Treatment Option Overview section for further information on the therapies listed below.

The following treatments may be used to treat recurrent parathyroid cancer:

  • Surgery (metastasectomy) to remove cancer from recurrent locations.
  • Surgery (tumour debulking) (tumor debulking).
  • Radiation treatment was used after surgery.
  • Radiation treatment.
  • Treatment of hypercalcemia with supportive care (too much calcium in the blood).

Localized Parathyroid Cancer Treatment

See the Treatment Option Overview section for further information on the therapies listed below.

Localized parathyroid cancer treatment may involve the following:

  • Surgery (en bloc resection) (en bloc resection).
  • Radiation treatment was used after surgery.
  • Radiation treatment.
  • Treatment of hypercalcemia with supportive care (too much calcium in the blood).

Additional testing may be required.

Some of the tests used to diagnose cancer or determine the stage of cancer may be repeated. Some tests will be repeated to see how effective the therapy is. The findings of these tests may be used to make decisions on whether to continue, adjust, or discontinue therapy.

Some of the tests will continue to be performed after the therapy has concluded. These tests might reveal if your health has altered or whether cancer has returned (come back). These exams are often known as follow-up testing or check-ups.

Parathyroid carcinoma frequently recurs. Patients should undergo monthly check-ups throughout the remainder of their lives to detect and treat recurrences as soon as possible.
