Insights

Tyrosine kinase inhibitors (TKIs) offer promising treatments for advanced thyroid cancers by targeting angiogenesis. Understanding and managing their adverse events is crucial for effective long-term therapy.

Area of Science:

  • Oncology
  • Pharmacology

Background:

  • Metastatic medullary and differentiated thyroid cancers are treated with tyrosine kinase inhibitors (TKIs) targeting angiogenesis.
  • Commercially available TKIs include sorafenib, sunitinib, and pazopanib.
  • Vandetanib is US-approved for medullary thyroid cancer.

Purpose of the Study:

  • To review the adverse event profiles of TKIs used in thyroid cancer.
  • To discuss the management of common toxicities associated with these therapies.
  • To address challenging situations encountered during chronic TKI treatment for thyroid cancer.

Main Methods:

  • Literature review of clinical studies and drug approvals.
  • Analysis of adverse event data from published trials.
  • Clinical experience in managing TKI-related toxicities.

Main Results:

  • TKIs targeting angiogenesis are effective for metastatic thyroid cancers.
  • Common toxicities require careful monitoring and management.
  • Adherence to therapy depends on managing adverse events.

Conclusions:

  • TKIs represent a significant therapeutic advance for advanced thyroid cancers.
  • Proactive management of TKI-induced toxicities is essential for patient benefit.
  • Understanding and mitigating adverse events optimizes chronic TKI therapy in thyroid cancer.

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

Pharmacogenetics of Drug Targets: β₂-Adrenergic Receptors, Apo E, Thymidylate Synthase

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...
