Globally,gastric cancer is the 4thmost frequently diagnosed cancer and the 2ndleading cause of death from cancer,with an estimated 990000 new cases and738000 deaths registered in 2008.In the advanced setting,standard chemotherapies protocols acquired an important role since last decades in prolong survival.Moreover,recent advances in molecular therapies provided a new interesting weapon to treat advanced gastric cancer through anti-human epidermal growth factor receptor 2(HER2)therapies.Trastuzumab,an anti-HER2 monoclonal antibody,was the first target drug in the metastatic setting that showed benefit in overall survival when in association with platinum-5-fluorouracil based chemotherapy.Further,HER2 overexpression analysis acquired a main role in predict response for trastuzumab in this field.Thus,we conducted a review that will discuss the main points concerning trastuzumab and HER2 in gastric cancer,providing a comprehensive overview of molecular mechanisms and novel trials involved.
