Core tip: Advanced gastric cancer (GC) has very poor outcome with chemotherapy remains the main treatment. There is an urgent unmet need to develop novel therapy for GC. Limited success is achieved for targeted therapy after trastuzumab for human epidermal growth factor receptor 2 positive disease. Ramucirumab was recently approved by Food and Drug Administration as a single agent or combined with paclitaxel in refractory advanced GC patients. Immune therapy and GC stem cell research are on the horizon.
