What Is Pediatric Thyroid Cancer

Why Do People Get Thyroid Cancer? | Masha Livhits, MD, and Yasmine Assadipour, MD | UCLAMDChat

The thyroid is a butterfly-shaped gland in the neck that produces hormones that are important for growth and metabolism. Pediatric thyroid cancer occurs when the cells in the thyroid gland become abnormal and grow out of control.

Thyroid cancer is an uncommon cancer in childhood: Fewer than one in 100,000 children develop thyroid cancer each year. Although it can occur at any age, childhood thyroid cancer is most common in the teenage years, and it is the second most common cancer among adolescents ages 15 to 19.

Thyroid cancer is often detected as a lump in the front of the neck found by the child, a parent, or by a physician during a routine examination. Some thyroid cancers are discovered by chance during medical imaging performed for another reason.

Although thyroid cancer can spread usually to the lymph nodes in the neck, or less often to the lungs most children with thyroid cancer respond very well to treatment. Thyroid cancer in children does not behave the same as it does in adult patients, and outcomes in children are generally better than in adults.

There are several types of thyroid cancer:

What Is The Prognosis Of Medullary Thyroid Cancer

The prognosis of MTC is usually not as favorable as differentiated thyroid cancers . However, if discovered early, surgery can be curative. Even in cases where it is not caught early, MTC often progresses relatively slowly. Long-term survival depends on the stage of disease at the time of diagnosis. The blood levels of calcitonin or CEA over the first year after surgery can also be a predictor of a patients survival.

How Is Thyroid Cancer Managed Or Treated

Treatments for thyroid cancer depend on the tumor size and whether the cancer has spread. Treatments include:

  • Surgery: Surgery is the most common treatment for thyroid cancer. Depending on the tumors size and location, your surgeon may remove part of the thyroid gland or all of the gland . Your surgeon also removes any nearby lymph nodes where cancer cells have spread.
  • Radioiodine therapy: With radioiodine therapy, you swallow a pill or liquid containing a higher dose of radioactive iodine than whats used in a diagnostic radioiodine scan. The radioiodine shrinks and destroys the diseased thyroid gland along with cancer cells. Dont be alarmed this treatment is very safe. Your thyroid gland absorbs almost all of the radioiodine. The rest of your body has minimal radiation exposure.
  • Radiation therapy: Radiation kills cancer cells and stops them from growing. External radiation therapy uses a machine to deliver strong beams of energy directly to the tumor site. Internal radiation therapy involves placing radioactive seeds in or around the tumor.
  • Chemotherapy: Intravenous or oral chemotherapy drugs kill cancer cells and stops cancer growth. Very few patients diagnosed with thyroid cancer will ever need chemotherapy.
  • Hormone therapy: This treatment blocks the release of hormones that can cause cancer to spread or come back.

Thyroid Cancer Survival Rate

Pin on Alicia D

Most thyroid cancers are very curable. In fact, the most common types of thyroid cancer papillary and follicular cancers have a more than 98% cure rate if theyre caught and treated at an early stage. The earlier you are diagnosed, the less likely it is that your cancer will have spread beyond the thyroid and the easier it is to treat.

Medullary thyroid cancer has a worse prognosis and is likely to include lymph node involvement. Once cancer has entered the lymph nodes it spreads readily through the lymphatic system, meaning your cancer will require more extensive and possibly more aggressive treatment.

The least common type of thyroid cancer, anaplastic thyroid cancer, has a very poor prognosis. The best results occur when localized anaplastic thyroid cancer is diagnosed early and completely removed via a thyroidectomy, as its very aggressive. Unfortunately, this cancer tends to be found after it has already spread.

Because most people dont die from thyroid cancer, its sometimes called a good cancer to get even by some physicians. Almost everyone I take care of has heard that, Dr. Lieb says. But I take issue with it. Physicians can feel very bad telling people they have cancer, and rather than saying your prognosis is good, some downplay the diagnosis. But there isnt a good cancer.

What Is Thyroid Cancer

Thyroid cancer is a type of cancer that starts in the thyroid gland. It happens when cells in the thyroid grow out of control and crowd out normal cells.

Thyroid cancer cells can spread to other parts of the body such as the lungs and the bone and grow there. When cancer cells do this, its called metastasis. But the type of cancer is based on the type of cells it started from.

So even if thyroid cancer spreads to the lung , its still called thyroid cancer, not called lung cancer.

Biochemical Testing For Mtc

Because MTC cells produce calcitonin, elevated serum calcitonin levels are diagnostic of MTC. Although routine measurement of serum calcitonin has low yield in managing the solitary thyroid nodule because of the uncommon nature of MTCs, it is useful in the surveillance of patients with a history of MTC and in managing familial forms. Stimulating calcitonin release by using intravenous pentagastrin increases the sensitivity of the test. For pentagastrin-stimulated calcitonin evaluation, a baseline plasma calcitonin level is measured, followed by the intravenous administration of pentagastrin 0.5 mg/kg and serial measurements of calcitonin 1.5 and 5 minutes after injection. Elevated basal or stimulated calcitonin levels above the normal range for the laboratory strongly suggest MTC.

Plasma calcitonin levels are commonly increased before clinical evidence of MTC appears. Although this finding was once the mainstay in diagnosing familial forms of MTC, results of genetic testing have largely supplanted it. Plasma calcitonin testing is now used for the early detection of MTC in patients already known to be at risk for MTC because of their family history and genetic results. This level is most commonly used as a tumor marker to identify residual and metastatic disease after thyroidectomy to treat MTC.

Thyroid Cancer: Common In Women

Thyroid disorders are more common in women, probably due to the roles of hormones, which are different in femalesthan in males.

Thyroid nodules, Russell says, affect up to 80 percent of women, but only 5percent to 15 percent of those lumps and bumps are malignant. Bettertesting means thyroid tumors are on the rise, he notes, saying that itsprojected to become the third most common cancer.

Malignant and cancer are scary words, but Russell says that mostthyroid cancer is highly treatable, even when the cancer cells spread tonearby lymph nodes, which occurs frequently.

With thyroid cancer we talk about prognosis in terms of 20-year survivalinstead of five years, as we do with most other cancers. Its usually aslow-moving disease. Theres a 98 to 99 percent survival rate at 20 years,he says.

We treat it almost like a chronic condition where the patient getstreatment and visits her doctor regularly for follow-up.

Signs Of Thyroid Cancer That Most People Miss

Recurrent Thyroid Cancer – How Do We Know? What Do We Do?

The thyroid is a butterfly-shaped endocrine gland in the neck. It produces two hormones, triiodothyronine and thyroxine , that regulate the bodys metabolism. Often, people attribute the first signs of thyroid cancer to other conditions.

Further, its essential to understand that the thyroid carries responsibility for hormone regulation. If the thyroid produces too much hormone, the patients metabolism is too fast, and they become hyperthyroid. If the thyroid produces too little hormone, the patients metabolism is sluggish, and they become hypothyroid.

Thus any thyroid disease can cause severe illnesses.

Final Thoughts On Knowing The Symptoms Of Thyroid Cancer

The American Cancer Society described thyroid cancer as the most rapidly increasing type of cancer in the US until recently. Much of that increase, however, stems from improved methods of detection, such as the MRI or CT.

If caught early, the prognosis for cancer of the thyroid is generally good. The Cleveland Clinic reported that over 90 percent of patients treated for papillary or follicular cancer, the most common types, were still alive five years later. The five-year survival rate for patients with MTC is somewhat less: 86 percent.

Unfortunately, the outlook for a patient with anaplastic cancer is far grimmer. Mercifully, anaplastic cancer is by far the least common type.

Most cases of cancer are diagnosed after the patient or their doctor spots a lump on the neck. Anybody who spots a lump on their neck should, therefore, have their doctor examine it, even if they feel fine otherwise.

When To Get Medical Advice

See a GP if you have symptoms of thyroid cancer. The symptoms may be caused by less serious conditions, such as an enlarged thyroid , so it’s important to get them checked.

A GP will examine your neck and can organise a blood test to check how well your thyroid is working.

If they think you could have cancer or they’re not sure what’s causing your symptoms, you’ll be referred to a hospital specialist for more tests.

How Is Medullary Thyroid Cancer Treated

Thyroid Cancer Can Lead to Hypertension

MTC is usually treated by removing the thyroid. This surgery is called a thyroidectomy. In certain people with a high risk for MTC, such as people carrying certain gene changes, a thyroidectomy may be performed to prevent cancer.

Besides surgery, sometimes other treatments are also required, including radiation therapy or chemotherapy. Also, targeted therapies are available that act on changes in DNA found in some cases of MTC.

After treatment, your doctor will monitor levels of a tumor marker called CEA and the hormones produced by C cells to keep track of how well the treatment is working or if cancer has come back. CEA is a type of tumor marker found in the blood of those with MTC.

How Serious Is My Cancer

If you have thyroid cancer, the doctor will want to find out how far it has spread. This is called staging. You may have heard other people say that their cancer was stage 1 or stage 2. Your doctor will want to find out the stage of your cancer to help decide what type of treatment is best for you.

The stage describes the spread of the cancer through the thyroid gland. It also tells if the cancer has spread to other organs of your body that are close by or far away.

Your cancer can be stage 1, 2, 3, or 4. The lower the number, the less the cancer has spread. A higher number, like stage 4, means a more serious cancer that has spread outside of the thyroid gland. Be sure to ask the doctor about the cancer stage and what it means for you.

What Kind Of Support Is Available For Those With Thyroid Cancer

Patients, families, and friends are all affected by a diagnosis of cancer is made. Support is available not only for the patient but for all those who are close to the patient. Hospitals, clinics, and health care professionals’ offices often have specially trained staff to help patients and families address their physical, emotional, and spiritual needs.

It is important for the patient and family to understand the disease, the treatment options, the expected outcomes, and the journey that will occur with cancer. Family members will benefit from being present for provider visits during the diagnosis and treatment, as well as with follow-up appointments. This allows all to be involved in advocating for the patient, since there is so much information to understand and absorb it can be overwhelming.

There are many community resources available as well. The American Cancer Society is a good place to begin. They have local offices and may be contacted online.

What Are The Complications Of Thyroid Cancer

Most thyroid cancers respond well to treatment and arent life-threatening.

After thyroid surgery or treatments, your body still needs thyroid hormones to function. Youll need thyroid replacement hormone therapy for life. Synthetic thyroid hormones, such as levothyroxine , take over for the thyroid hormones that your body no longer naturally produces.

A cancer diagnosis is always worrisome, but even if a nodule turns out to be thyroid cancer, you still have plenty of reasons to be hopeful.

Thyroid cancer is one of the most treatable kinds of cancer. Surgery to remove the gland typically addresses the problem, and recurrences or spread of the cancer cells are both uncommon. People who undergo thyroid gland surgery may need to take thyroid hormone afterward to keep their body chemistry in balance.

Whether its benign or not, a bothersome thyroid nodule can often be successfully managed. Choosing an experienced specialist can mean more options to help personalize your treatment and achieve better results.

How We Care For Thyroid Cancer In Children

The team of clinicians in the Thyroid Center at Boston Childrens Hospital treats children and adolescents with thyroid cancer. Founded in 2001, the Thyroid Center is the oldest program of its kind in the country, and one of the only centers in the U.S. devoted exclusively to the care of children with thyroid diseases. The specialists in this multidisciplinary program have expertise in thyroid ultrasound, fine needle aspiration, thyroid surgery, nuclear medicine imaging, and radioactive iodine therapy.

Surgical experience is critical to having the best outcomes from thyroid cancer surgery, so its important to take the time to choose a surgeon who specializes in thyroid cancer in children. The rate of surgical complications is higher in children with thyroid cancer than in adults, perhaps because few pediatric surgeons are well versed in its treatment. Fortunately, thyroid cancer grows slowly, which gives families the opportunity to find a skilled pediatric thyroid surgeon or to seek a second opinion.

At Boston Childrens Thyroid Center, our pediatric thyroid surgeons specialize in the care of children and adolescents with thyroid disease, making us one of the most experienced centers of its kind in the country. This breadth and depth of knowledge result in exceptional outcomes and a low rate of surgical complications, which means that you can trust that your child is in the best hands.

Take A Sip And Take A Look

Take a sip of water and tilt your head back with your chin up, and keep an eye on your throat and neck as you swallow.

You may need to do this several times to get a good look at your neck as you swallowkeeping your chin up and your eyes down on the mirror can be a bit tricky at first.

Watch the thyroid area as you swallow, looking for any bulges near the area where your thyroid gland would be. Is the area symmetrical as you swallow, or is there a difference between the sides.

Sarcoma Of The Thyroid Gland

Sarcomas that arise in the thyroid gland are uncommon. They are aggressive tumors that most likely arise from stromal or vascular tissue in the gland. Malignancies that appear to be sarcomas should be differentiated from anaplastic thyroid carcinomas, which can appear sarcomatous.

The treatment for thyroid sarcomas is total thyroidectomy. Radiation therapy may be used in an adjunctive setting. Most sarcomas are unresponsive to chemotherapy. Recurrence is common, as it is with sarcomas arising in other sites in the body, and the patient’s overall prognosis is poor.

Evaluation And Management Of The Solitary Thyroid Nodule

What happens when you have thyroid problems? How this ...

The key to the workup of the solitary thyroid nodule is to differentiate malignant from benign disease and, thus, to determine which patients require intervention and which patients may be monitored serially. History taking, physical examination, laboratory evaluation, and fine-needle aspiration biopsy are the mainstays in the evaluation of thyroid nodules. Imaging studies can be adjuncts in select cases.
