Abstract :

Statement of the Problem: Lenvatinib is an oral, multitargeted tyrosine kinase inhibitor (TKI) of VEGFR1-VEGFR3, FGFR1FGFR4, PDGFR�±, RET and v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (KIT) signaling networks involved in tumor angiogenesis. The antitumor activity of lenvatinib has been investigated in primary anaplastic thyroid cancer (ATC) cells, in the human cell line 8305C (undifferentiated thyroid cancer) and in an ATC-cell line (AF). Methodology & Theoretical Orientation: The effect of lenvatinib (1 nM, 100 nM, 1 mcM, 10 mcM, 25 mcM and 50 mcM) was evaluated in primary ATC cells, 8305C cells, and AF cells and in AF cells injected in CD (Crohnâ��s disease) nu/nu mice. Findings: Lenvatinib significantly reduced ATC cell proliferation (P<0.01, ANOVA) and increased the apoptosis (P<0.001, ANOVA). Furthermore, lenvatinib inhibited migration (P<0.01) and invasion (P<0.001) in ATC. Lenvatinib inhibited EGFR, AKT and ERK1/2 phosphorylation and down-regulated cyclin D1 in ATC cells. Moreover, lenvatinib significantly inhibited 8305C and AF cell proliferation, increasing apoptosis. AF cells were injected subcutaneously into CD nu/nu mice and tumor masses were evident after 20 days. Tumor growth was significantly inhibited by lenvatinib (25 mg/kg/day), as the VEGF-A expression and microvessel density in AF tumor tissues. Conclusion & Significance: We have shown for the first time the antitumoral effect of the multi-targeted kinase inhibitor lenvatinib, in primary human ATC cell cultures obtained from patients. These findings could open the way to the clinical use of lenvatinib in the treatment of patients with ATC. Recent Publications 1. Antonelli A, Fallahi P, Ulisse S, Ferrari S M, Minuto M et al.
