Abstract

The five-year survival for patients with gastric cancer improved only modestly over the last 50 years. So, several studies about molecular target chemotherapy were investigated. We reviewed about molecular target chemotherapy for advanced unresectable and metastatic gastric cancer, which has developed recently. EGFR (Epidermal growth factor receptor), HER(Human epidermal growth factor receptor), VEGF (Vascular endothelial growth factor receptor) can be the target of therapy for gastric cancer. Patients with advanced gastric adenocarcinoma who are potential candidates for trastuzumab should have their tumors assayed for the presence of HER2 overexpression utilizing tumor-specific criteria and/or gene amplification. We suggest the addition of trastuzumab to chemotherapy in patients with HER2-positive tumors (as defined by 3+ immunohistochemical staining or FISH positivity), as long as they do not have a contraindication to trastuzumab. Except for trastuzumab, we summarized several studies for molecular target agents which were not validated yet.
