Abstract
Gastric cancer remains a leading cause of cancer-related death in the world. FGF receptor 2 (FGFR2) is preferentially amplified and overexpressed in the diffuse type of gastric cancer. This review evaluates the expression and function of FGFR2 in gastric cancer, and analyzes the use of its inhibitors for gastric cancer therapy. This review also discusses the limitations of FGFR2-based therapy, and envisages future developments toward the clinical applications of FGFR2.

Key issues
• Gastric cancer remains a leading cause of death worldwide, and effective target therapy is urgently needed.
• FGF receptor 2 (FGFR2) is preferentially amplified and overexpressed in the diffuse-type gastric cancer.
• Inhibitors of FGFR2 can induce growth inhibition, apoptosis and drug sensitivity of gastric cancer cells in vitro and in vivo.
• Inhibitors of FGFR2 show synergistic anti-tumor effects for gastric cancer cells in combination with chemotherapeutic drugs.
• FGFR2 is considered as one valuable target for gastric cancer treatment.
• More clinical trials should be performed to promote the use of FGFR2 in clinic.
