Thyroid Cancer Treatment Pathway

See where clinical trials fit into your treatment journey

Differentiated (Early Stage)

Papillary or follicular thyroid cancer β€” often curable with surgery

Standard: Surgery (thyroidectomy) Β± radioactive iodine ablation, TSH suppression

Radioactive Iodine-Refractory

Cancer no longer responds to radioactive iodine treatment

Standard: Lenvatinib or Sorafenib (tyrosine kinase inhibitors)

Medullary Thyroid Cancer

Rare type arising from C-cells, often hereditary (MEN2)

Standard: Vandetanib or Cabozantinib for advanced disease

Anaplastic Thyroid Cancer

Rare, aggressive form requiring rapid treatment

Standard: Combination chemo-radiotherapy, immunotherapy trials emerging

Key Biomarkers

BRAF V600E

Found in ~45% of papillary thyroid cancers. Predicts response to BRAF-targeted therapies and informs radioactive iodine sensitivity.

RET Mutation

Present in nearly all medullary thyroid cancers. RET inhibitors (Selpercatinib, Pralsetinib) target this mutation specifically.

NTRK Fusion

Found in ~5% of thyroid cancers. NTRK inhibitor trials (Larotrectinib, Entrectinib) are available for fusion-positive tumours.

RAS Mutation

Common in follicular thyroid cancer. May indicate progression risk and influence treatment choices.

Frequently Asked Questions

Yes. Several trials target BRAF mutations, RET fusions, and NTRK fusions in thyroid cancer. Newer trials also explore immunotherapy combinations, particularly for iodine-refractory and anaplastic thyroid cancer.

When thyroid cancer no longer responds to radioactive iodine treatment (RAI-refractory), targeted therapies like Lenvatinib or Sorafenib become the standard option. Clinical trials offer access to newer TKIs and immunotherapy approaches.

Yes. Medullary thyroid cancer (MTC) has specific trials for RET inhibitors like Selpercatinib and Pralsetinib. There are also trials exploring combination approaches for progressive or advanced MTC.
