You asked: Can follicular thyroid cancer turn into anaplastic?


Can papillary thyroid cancer turn into anaplastic thyroid cancer?

The transformation of papillary thyroid carcinoma (PTC) to anaplastic thyroid carcinoma (ATC) is well documented in the literature but is an exceptionally rare occurrence in metastatic foci outside the primary thyroid lesion. Even rarer is the simultaneous occurrence of PTC and ATC in the cervical lymph nodes.

What percentage of thyroid cancer is anaplastic?

Only 1-2% of thyroid cancers are anaplastic, but the disease contributes to 14–50% of the mortality with a median survival of 3 to 5 months. Most patients diagnosed with this disease are 65 years of age or older. The incidence of anaplastic thyroid cancer is decreasing worldwide.

Is follicular thyroid cancer curable?

Most thyroid cancers are very curable. In fact, the most common types of thyroid cancer (papillary and follicular thyroid cancer) are the most curable. In younger patients, less than 50 years of age, both papillary and follicular cancers have a more than 98% cure rate if treated appropriately.

Can anaplastic thyroid cancer be misdiagnosed?

Two cases of undifferentiated (anaplastic) thyroid carcinoma were misdiagnosed as papillary thyroid carcinoma. Both patients received total thyroidectomies, which may not otherwise have been performed.

What are the symptoms of anaplastic thyroid cancer?

But anaplastic thyroid cancer often grows quickly and cause symptoms that may include:

  • Cough, with or without blood.
  • Trouble swallowing.
  • Hoarse or changed voice.
  • Loud or troubled breathing.
  • Lump in your lower neck.
  • Pain or pressure in your neck.
  • Food or pills getting “stuck” when you swallow.

How long can you live with Stage 4 thyroid cancer?

Stage 4: In this stage, the tumor has spread into neck tissues under the skin, the trachea, esophagus, the larynx, or distant parts of the body such as the lungs or bones. The 10-year outlook significantly declines at this point: Only 21 percent of people diagnosed at this stage are alive after 10 years.

Where does anaplastic thyroid cancer spread?

Spread to lymph nodes of the neck in over 90% of cases. Extension of the anaplastic thyroid cancer into adjacent tissue is common. Distant spread to lung, bones, and liver commonly occurs even with initial diagnosis. Rarely found in younger patients.

Is follicular thyroid cancer fatal?

Papillary thyroid cancer is highly curable and rarely fatal. Follicular: Follicular thyroid cancer accounts for up to 15% of thyroid cancer diagnoses. This cancer is more likely to spread to bones and organs, like the lungs. Metastatic cancer (cancer that spreads) can be more challenging to treat.

Is follicular thyroid cancer slow growing?

Papillary and follicular thyroid cancers account for more than 90% of all thyroid cancers. They tend to grow very slowly.

How quickly does anaplastic thyroid cancer grow?

Unlike most thyroid cancers which do not cause symptoms, anaplastic cancers tend to grow very quickly (sometimes over a few weeks) and cause compressive symptoms which include difficulty swallowing, food or pills getting “stuck” when they swallow, and pressure or shortness of breath when lying flat.

What happens to your body when you have thyroid cancer?

The most common locations for metastatic thyroid cancer are the lungs, liver and bones. If tumors develop in these (or other) parts of the body, complications such as pain, swelling and organ failure can occur.

Where Does thyroid cancer spread first?

Most patients with thyroid cancer have the cancer contained in the thyroid at the time of diagnosis. About 30% will have metastatic cancer, with most having spread of the cancer to the lymph nodes in the neck and only 1-4% having spread of the cancer outside of the neck to other organs such as the lungs and bone.

Is follicular thyroid cancer common?

Follicular thyroid carcinoma (FTC) is the second most common cancer of the thyroid, after papillary carcinoma. Follicular and papillary thyroid cancers are considered to be differentiated thyroid cancers; together they make up 95% of thyroid cancer cases.
