Gatrointestinal junction(GE) cancer (where esophagus and stomach meet) is a type of cancer that has similarities to both gastric and esophageal cancer. Since GE Junctions cancers that express HER turned out to respond well to Herceptin, there is great interest in targeting other molecules, such as the epidermal growth factor receptor, vascular endothelial growth factor receptor, and P13k/Akt/mTor pathway, as well as the insulin-like growth factor receptor, c-Met pathways, fibroblast growth factor receptor, and other pathways in this type of cancer. Much remains to be done before clinical therapies based on this concept become available and proven but there is much research activity. One study looking at a C-MET inhibitor is: MET111643 ,A Phase 2 Study of GSK1363089 (XL880) Administered Orally to Subjects with Metastatic Gastric Cancer.
