Low-dose apatinib monotherapy in advanced chemotherapy-refractory small cell lung cancer: a case series and literature review.

ABSTRACT: The therapeutic regimen for small cell lung cancer (SCLC) has changed little in the past several decades. Apatinib is a small molecule inhibitor of vascular endothelial growth factor receptor-2 tyrosine kinase. Apatinib has demonstrated efficacy against advanced gastric cancer and breast cancer, and recent studies have also reported its successful use in non-SCLC; however, its efficacy in SCLC remains unclear. In this study, we used apatinib as salvage therapy for chemotherapy-refractory SCLC. Five male patients with advanced SCLC were administered oral apatinib (250 mg/day) as 2nd- to 4th-line treatment. One patient showed a partial response to apatinib, one showed stable disease, and three patients showed progressive disease. The progression-free survival durations in the patients with stable disease and partial response were 1.5 and 3 months, respectively. Only three patients showed adverse effects, including mild hypertension, vomiting, and hand-foot syndrome, respectively, all of which were manageable. Apatinib might thus be a salvage option in patients with advanced SCLC after chemotherapy.
