Symptoms — what the patient reports (4)

  • Most patients present with a noticed neck swelling or an incidentally found thyroid nodule on imaging [neck lump]
  • A concerning history includes rapid nodule growth with pressure symptoms such as voice hoarseness, difficulty swallowing, breathlessness, or Horner syndrome [breathlessness · difficulty swallowing · hoarseness]
  • A family history of thyroid cancer, prior childhood head or neck radiation, or systemic symptoms like weight loss and fatigue also raise concern [fatigue · weight loss]
  • Anaplastic thyroid cancer instead causes a rapidly growing neck mass with quick-onset compressive symptoms, plus fever, weight loss, or loss of appetite [fever · neck lump · poor appetite · weight loss]

Signs — what you find (1)

  • A firm, fixed nodule with palpable neck lymph nodes on exam should raise suspicion for cancer

Tests (12)

  • Thyroid function testing is the recommended first step in evaluating any thyroid nodule
  • A hyperthyroid patient has a lower malignancy risk and should get a radionuclide uptake scan instead
  • Biopsy is generally avoided for a hyperfunctioning nodule because these are rarely malignant and biopsy results are often inaccurate
  • A euthyroid or hypothyroid nodule is evaluated first with a high-resolution thyroid ultrasound
  • High-risk ultrasound features include growth on prior imaging, a dark appearance, irregular margins, a taller-than-wide shape, microcalcifications, a solid structure, extension beyond the thyroid, and central blood flow
  • Features suggesting lower risk include a fully cystic nodule, a spongiform pattern, comet-tail shadowing, and blood flow only at the edges
  • Biopsy accuracy depends heavily on operator and pathologist skill, ranging from 70% to 97%, and 17% to 20% of samples come back insufficient
  • Biopsy diagnoses papillary cancer well but cannot confirm follicular cancer, which needs final surgical pathology to check for capsular or vascular invasion
  • A Bethesda Category 1 result is non-diagnostic and calls for repeat biopsy
  • Bethesda Categories 5 and 6 (suspicious or malignant) usually go straight to surgery
  • Single-mutation molecular tests like BRAF V600E have 100% specificity but only 50-60% sensitivity for indeterminate nodules
  • A gene expression classifier has a strong negative predictive value but only about 50% positive predictive value, making it a good rule-out test

If not this — what else fits (4)

  • Benign thyroid nodule
  • Toxic nodular goiter
  • Primary thyroid lymphoma
  • Cervical lymphadenopathy

NO DRUG THERAPY IN PRIMARY CARE (REFERRAL & ADVICE)

1st line
Adult dose and duration

Thyroid cancer requires surgical and oncologic management; the GP's role is to recognise a suspicious thyroid nodule and refer promptly. - Refer, with advice

Paediatric dose

Children follow the same pathway: recognise and refer. No primary-care medicine is implied.

Dose source

No dose - referral pathway, no medicine given in primary care

Why

Thyroid cancer requires surgical and oncologic management; the GP's role is to recognise a suspicious thyroid nodule and refer promptly.

Cautions
  • A rapidly enlarging neck mass, hoarseness, difficulty swallowing, neck lymph node swelling, or a fixed hard nodule are all urgent referral triggers.
  • No medicine is prescribed for this in primary care - this entry is for recognition and referral. Anything given is decided by the service it is referred to.
  • RED FLAG - Specific features that should trigger suspicion of malignancy in a thyroid nodule and prompt referral, beyond generic 'suspicious nodule'
  • RED FLAG - Rapidly enlarging neck mass with airway/aerodigestive compressive symptoms suggests anaplastic thyroid cancer, a much more urgent presentation.
