Use of erlotinib and thalidomide in advanced NSCLC patients with acquired resistance to erlotinib: A pilot study.

Evidences suggested that combined blockade of the VEGF and EGFR pathways can improve the treatment efficacy of non-small-cell lung cancer (NSCLC). In our previously clinical practice, we observed that thalidomide, a potent VEGF inhibitor, can significantly decrease the tumor size of one EGFR-TKI resistance patient with lung cancer cachexia. In this pilot study, we tried to assess the efficacy and toxicity of the combination therapy of erlotinib and thalidomide in advanced NSCLC patients with acquired resistance to erlotinib.
