Or. Nonetheless, in the majority of nations, the majority of individuals are diagnosed at sophisticated stages and have a poor prognosis. Although first-line chemotherapy for advanced gastric cancer (AGC) prolongs all round survival (OS) and improves top quality of life compared with greatest supportive care (BSC). The median survival of advanced gastric cancer individuals who received palliative chemotherapy is approximately 7 to 11 months [4-8]. In 2010, trastuzumab (Herceptin, Roche, Basel, Switzerland), a recombinant humanized monoclonal antibody that targets human epidermal development aspect receptor-2 (HER2), had currently been confirmed to be* Correspondence: [email protected] Division of Medical Oncology, Sun Yat-Sen University Cancer Center, State Key Laboratory of Oncology in South China, Collaborative Innovation Center for Cancer Medicine, 651 Dong Feng Road East, Guangzhou 510060, Chinaeffective when combined with chemotherapy in HER2positive AGC patients [9]. Trastuzumab could be the first targeted agent that gets the indication in AGC, but it is not the only targeted agents which have tried their applications in AGC. The other therapeutic methods consist of: epidermal growth factor receptor (EGFR) inhibitors, vascular endothelial development factor (VEGF) inhibitors, hepatocyte growth issue (HGF) and its receptor c-MET pathway inhibitor, mammalian target of rapamycinm (m-TOR) inhibitor et al.3-Azidopropanoic acid Price This evaluation will focus around the current progress in targeted agents for the therapy of AGC (Table 1).EGFR-signaling pathwayEGFR exists on the cell surface and is part of the loved ones of TK receptor which includes HER2.2,4-Dimethyl-1H-pyrrole Formula EGFR overexpression has been reported in roughly 30 to 50 of gastric cancers and is related with poor prognosis [10-14].Anti-HER2 monoclonal antibodysHER2, a transmembrane tyrosine kinase (TK) receptor, could be the preferred heterodimerization companion with the other HER members of the family (HER1 or EGFR, HER3 and HER4). The HER2-HER3 heterodimer plays a important role in oncogenic transformation in HER2-driven tumors [15,16]. In breast cancer, amplification and overexpression from the HER2 gene is linked with poor outcomes, larger mortality, and larger recurrence also as?2013 Qiu and Xu; licensee BioMed Central Ltd.
