The antitumor activity of vandetanib [a multiple signal transduction inhibitor including the RET tyrosine kinase, epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF) receptor (VEGFR), ERK and with antiangiogenic activity], in primary anaplastic thyroid cancer (ATC) cells, in the human cell line 8305C [undifferentiated thyroid cancer (TC)] and in an ATC-cell line (AF), was investigated in the present study.

Introduction: Anaplastic thyroid cancer (ATC) is one of the most aggressive human malignancies (representing 15–40% of fatal TC cases), classified as stage IV by the American Joint Committee on Cancer, regardless of tumor size or presence of lymph node and distant metastases. A large number of genetic alterations are associated with ATC, especially causing dysfunctions in the ERK1/2-MEK1/2 and PI3K-AKT signaling pathways (BRAF, p53, RAS, EGFR, VEGFR1, VEGFR2, chromosomal rearrangements, etc). New drugs targeting these molecular pathways have recently been evaluated in ATC.
