Inhibition of non-small-cell lung cancer growth by combined fulvestrant and vandetanib.
Evaluation of: Siegfried JM, Gubish CT, Rothstein ME, Henry C, Stabile LP. Combining the multitargeted tyrosine kinase inhibitor vandetanib with the antiestrogen fulvestrant enhances its antitumor effect in non-small cell lung cancer. J. Thorac. Oncol. 7(3), 485-495 (2012). Targeting the EGF receptor (EGFR) with tyrosine kinase inhibitors (TKIs) shows clinical efficacy for some non-small-cell lung cancer (NSCLC) patients. Recent studies have demonstrated that NSCLCs express estrogen receptors and that fulvestrant, an antiestrogen that reduces estrogen receptor protein, inhibits cell proliferation. Combination of a TKI targeting EGFR and fulvestrant shows greater efficacy than TKI or fulvestrant alone. This study demonstrated that treatment of NSCLC cells with vandetanib, a TKI of EGFR and VEGF receptor, and fulvestrant showed greater efficacy for inhibition of cell proliferation in vitro or xenograft tumor growth in vivo than either drug alone. These preclinical data provide rationale for a clinical trial to test efficacy in NSCLC patients.[1]References
