Advanced Differentiated Thyroid Cancer:

Targeted, Multireceptor Kinase Inhibition to
Slow Disease Progression and Prolong Progression Free Survival


INTENDED AUDIENCE

The intended audience for this activity is endocrinologists, medical oncologists, and primary care physicians who wish to broaden and update their knowledge of the management and treatment of locally advanced or metastatic differentiated thyroid cancer.

STATEMENT OF NEED

Differentiated thyroid cancer (DTC) has a generally good prognosis, but median survival for patients with advanced, radioactive iodine-refractory (RAI-R) DTC and distant metastases is estimated to be 3 to 6 years. Unfortunately, effective treatments for these patients have been lacking. Thus, new treatment options have long been needed for RAI-R patients with DTC who have a poor prognosis.

In recent years, research has been elucidating the aberrant metabolic pathways within cells that allow the development of cancers and identifying targeted therapies based on inhibition of these pathways. Since solid tumors require blood to supply the nutrients required for growth, one potential objective for targeted therapy is inhibition of angiogenesis. Agents that inhibit angiogenesis by interrupting signaling pathways, including tyrosine kinase inhibitors (TKIs), are currently being investigated for treatment of RAI-R DTC. Sorafenib, an orally active agent that targets various tyrosine and RAF (serine/threonine) kinases in tumor cells and tumor vasculature, is currently indicated for the treatment of advanced hepatocellular carcinoma and renal cell carcinoma. Sorafenib is recently approved to treat late-stage (metastatic) differentiated thyroid cancer. A number of other TKIs are in the pipeline, in Phase 2 or early Phase 3 trials.

Physicians need to be thoroughly familiar with the molecular targets and the efficacy and safety profiles of these various agents to assess the patient's suitability for treatment, customize the treatment choice, monitor appropriately, and manage AEs as they occur to optimize outcomes, maintain patient compliance to the treatment regimen, and avoid potentially life-threatening consequences. The aim of this monograph is to educate physicians who have had limited experience with these agents about their efficacy and safety.

EDUCATIONAL OBJECTIVES

Patient outcomes could be measurably improved if physicians were better able to...

  1. Discuss the role of VEGFR tyrosine kinase activity and cross-signaling between multiple kinase pathways in thyroid tumorigenesis, progression, and metastasis
  2. Identify the significance of genetic alterations in the pathogenesis of advanced differentiated thyroid cancer
  3. Associate the most predominant RAF signal kinase with its potent role in MAPK pathway signaling
  4. Review the fundamental role that signaling gene mutations may play in thyroid tumorigenesis
  5. Evaluate the effectiveness of targeted therapies that inhibit pathways constitutively activated during early stages of tumor development
