ABSTRACT
Introduction: Gastric cancer (GC) is a health problem. Platinum and fluoropyrimidine-based combinations have been established as first-line drugs used worldwide. However, there are no other options for treatment if first-line therapy fails. Therefore, second-line treatment options are needed. Targeted therapies have optimized the results of chemotherapy, specifically trastuzumab as a first-line and ramucirumab in second-line.
Areas covered: Vascular endothelial growth factor (VEGF) and VEGF receptor-2 (VEGFR-2) are involved in the pathogenesis of GC. Clinical studies have evaluated VEGFR-2 blocked in second line. Two phase III trials using ramucirumab alone or associated to paclitaxel have demonstrated that second-line therapy could improve the survival of patients with GC.
Expert commentary: VEGF-2 receptor blockade is effective at treating GC. The combination of paclitaxel with ramucirumab can be used to establish an angiogenic blockade in second-line therapy. The magnitude of the treatment effect suggests that this combination should be used as the current standard.
