ObjectiveTo understand the research status of diagnosis and treatment of gastric hepatoid adenocarcinoma (GHA) in order to provide a reference for clinical.MethodThe relevant literatures on diagnosis and treatment of GHA at home and abroad in recent years were searched and reviewed.ResultsThe GHA was a special type of gastric cancer with adenoid and hepatocyte differentiations, and the incidence of GHA in all gastric cancers was less than 1%. The histological morphology of GHA was similar to that of hepatocellular carcinoma, which was often accompanied by elevated serum alpha-fetoprotein and was prone to lymph node and liver metastases. The radical surgery and adjuvant chemotherapy were the most important treatment methods. However, even when the radical resection was performed, the recurrence and metastasis were still common, and there was no standard chemotherapy regimen for GHA at present.ConclusionsGHA is a special subtype of gastric cancer with high malignancy, which has rapid clinical progress and poor prognosis. Pathomorphology is the gold standard for the diagnosis of GHA. The therapy of GHA is a comprehensive treatment based on operation and chemotherapy, and gene molecular characteristics and targeted therapy are the research directions in future.
