Progress in Research on HER2 and Gastric Cancer / 胃肠病学

ABSTRACT

This paper reviewed the progress in research on HER2 and gastric cancer,introducing the structure, signaling pathways,detection method and detection rate of HER2,the therapeutic effect of trastuzumab,a humanized anti-HER2 monoclonal antibody on gastric cancer,and the correlation between HER2 and prognosis of gastric cancer. Studies showed that HER2-positive was a factor with poor prognosis,and trastuzumab combined with chemotherapy was a new treatment option for patients with HER2-positive advanced gastric and gastroesophageal junction cancer or with liver metastases,which could significantly improve the prognosis.
