III. Types: Thyroid Carcinoma

  1. Papillary carcinoma (up to 80%)
    1. Insidious growth
    2. May go undiagnosed until metastases
  2. Follicular Carcinoma (10-25%)
    1. Female > Male
    2. Peaks at age 50-60 years
  3. Medullary Carcinoma (5-10%)
    1. Secretes multiple substances including Calcitonin
    2. Associated with Multiple Endocrine Neoplasia
      1. MEN IIa (Sipple's Syndrome)
        1. Pheochromocytoma and Parathyroid hyperplasia
      2. MEN IIb
        1. Pheochromocytoma and mucosal neuroma
  4. Undifferentiated Carcinoma (5-10%)
  5. Thyroid Lymphoma (5%)

IV. Risk Factors (and Red Flags)

  1. Male gender (especially under age 40 years)
  2. Age extremes (under age 20 and over age 65)
  3. Rapid painless growth of Thyroid Nodule
  4. Local symptoms consistent with invasion
    1. Dysphagia
    2. Neck Pain
    3. Hoarseness or raspy voice
  5. Head and neck radiation history
  6. Family History of Thyroid malignancy
    1. Thyroid Cancer
    2. Thyroid polyposis (Gardner's Syndrome)
  7. Thyroid fixation to skin or trachea
  8. Hard Nodule on palpation

V. Evaluation

VI. Prognosis

  1. Papillary carcinoma
    1. Best prognosis of Thyroid Cancer
    2. Ten year survival: 70-80%
  2. Follicular Carcinoma
    1. Five year survival: 30%
  3. Medullary Carcinoma
    1. Variable prognosis

Ontology: Thyroid carcinoma (C0549473)

Definition (MEDLINEPLUS)

Your thyroid is a butterfly-shaped gland in your neck, just above your collarbone. It makes hormones that help the body work normally. There are several types of cancer of the thyroid gland. You are at greater risk if you

  • Are between ages 25 and 65
  • Are a woman
  • Are Asian
  • Have a family member who has had thyroid disease
  • Have had radiation treatments to your head or neck

You should see a doctor if you have a lump or swelling in your neck. Doctors use a physical exam, blood tests, imaging tests, and a biopsy to diagnose thyroid cancer. Treatment depends on the type of cancer you have and how far the cancer has spread. Many patients receive a combination of treatments. They may include surgery, radioactive iodine, hormone treatment, radiation therapy, chemotherapy, or targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells.

NIH: National Cancer Institute

Definition (NCI) A carcinoma arising from the thyroid gland. It is usually an adenocarcinoma and includes the following main subtypes: follicular, papillary, medullary, poorly differentiated, and anaplastic.
Definition (NCI_NCI-GLOSS) Cancer that forms in the thyroid gland (an organ at the base of the throat that makes hormones that help control heart rate, blood pressure, body temperature, and weight). Four main types of thyroid cancer are papillary, follicular, medullary, and anaplastic thyroid cancer. The four types are based on how the cancer cells look under a microscope.
