Abstract:
Advanced thyroid cancer is not amenable to therapy with conventional cytotoxic chemotherapy. However, newer advances in the understanding of the molecular pathogenesis of different subtypes of thyroid cancer have provided new opportunities for the evaluation of molecularly targeted therapies. This has led to multiple clinical trials using various multi-kinase inhibitors and the subsequent US FDA approval of sorafenib for differentiated thyroid cancer and vandetanib and cabozantinib for medullary thyroid carcinoma. This review provides a summary of the current literature for the treatment of advanced thyroid carcinoma and future directions in this disease.
Insights
Advanced thyroid cancer lacks effective chemotherapy options. Molecularly targeted therapies, including multi-kinase inhibitors like sorafenib, vandetanib, and cabozantinib, now offer new treatment avenues for specific thyroid cancer subtypes.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Advanced thyroid cancer is largely resistant to traditional chemotherapy.
- Understanding molecular pathways has opened doors for targeted treatments.
Purpose of the Study:
- To review current literature on advanced thyroid carcinoma treatment.
- To discuss future directions in managing advanced thyroid cancer.
Main Methods:
- Literature review of studies on advanced thyroid cancer.
- Analysis of clinical trials involving molecularly targeted therapies.
- Summary of US FDA-approved drugs for thyroid cancer.
Main Results:
- Multi-kinase inhibitors show promise in treating advanced thyroid cancer.
- Sorafenib is approved for differentiated thyroid cancer.
- Vandetanib and cabozantinib are approved for medullary thyroid carcinoma.
Conclusions:
- Targeted therapies represent a significant advancement in treating advanced thyroid cancer.
- Further research is needed to explore novel therapeutic strategies.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
