Fibroblast growth factor receptor 2: a therapeutic target in gastric cancer

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.
