Apatinib as post second-line therapy in EGFR wild-type and ALK-negative advanced lung adenocarcinoma

摘要

In the absence of a driver mutation, chemotherapy is the standard treatment option as first- and second-line therapy for advanced non-small-cell lung cancer (NSCLC). Though a large number of patients are suitable for post second-line therapies, the quality and quantity of the available drugs in this setting is poor. Apatinib, a small molecule vascular endothelial growth factor receptor-2 (VEGFR-2) tyrosine kinase inhibitor, is a first-generation oral antiangiogenesis drug approved in the People’s Republic of China for use as a subsequent line of treatment for advanced gastric cancer. Herein, we report three cases of advanced NSCLC with epidermal growth factor receptor wild-type and anaplastic lymphoma kinase-negative status, wherein the patients showed partial response to apatinib. Moreover, the three patients have achieved a progression-free survival of 2.8, 5.8, and 6 months, respectively. The main toxicities were hypertension, proteinuria, and hand–foot syndrome. Apatinib may provide an additional option for the treatment of advanced NSCLC, especially for advanced lung adenocarcinoma without a driver mutation.
