    Anaplastic thyroid cancer

    Anaplastic carcinoma of the thyroid

    Anaplastic thyroid carcinoma is a rare and aggressive form of cancer of the thyroid gland.


    Anaplastic thyroid cancer grows very rapidly and is an invasive type of thyroid cancer. It occurs most often in people over age 60. The cause is unknown.

    Anaplastic cancer accounts for only about 1% of all thyroid cancers.


    • Cough
    • Coughing up blood
    • Difficulty swallowing
    • Hoarseness or changing voice
    • Loud breathing
    • Lower neck lump, which often grows quickly

    Exams and Tests

    A physical examination almost always show a neck growth.

    • A CT scan or MRI of the neck may show a tumor growing from the thyroid gland.
    • A thyroid biopsy shows anaplastic cancer.
    • An examination of the airway with a fiberoptic scope (laryngoscopy) may show a paralyzed vocal cord.
    • A thyroid scan shows this growth to be "cold," meaning it does not absorb a radioactive substance.

    Thyroid function blood tests are usually normal.


    This type of cancer cannot be cured by surgery. Complete removal of the thyroid gland does not prolongmost patients'life.

    Of other treatment options, only radiation therapy combined with chemotherapy has asignificant benefit.

    Surgery to place a tube in the throat to help with breathing (tracheostomy) or in the stomach to help with eating (gastrostomy) may be needed.

    For some patients, enrolling in a clinical trial of new thyroid cancer treatments may be an option.

    Support Groups

    You can often ease thestress of illness by joining a support group of people sharing common experiences and problems.

    Outlook (Prognosis)

    Theoutlook withthis disease is poor. Most people do not survive longer than 6 months because the disease is aggressiveand there is alack of effective treatment options.

    Possible Complications

    • Spread of tumor within the neck
    • Metastasis (spread) of cancer to other body tissues or organs

    When to Contact a Medical Professional
