Objective To discuss the clinical manifestations, diagnosis, and treatment of hepatoid adenocarcinoma of the stomach. Methods By summarizing the multi-disciplinary team results of 1 patient with hepatoid adenocarcinoma of the stomach, who underwent surgery in West China Hospital in October 2017, as well as reviewing the related literatures, to explore the clinicopathological features of hepatoid adenocarcinoma of the stomach. Results The clinical features of hepatoid adenocarcinoma of the stomach were often accompanied by early liver metastasis and alpha fetoprotein (AFP) significantly increased, which were easily misdiagnosed as primary hepatocellular carcinoma. The histopathological features of hepatoid adenocarcinoma of the stomach were characterized by two structures: hepatocellular carcinoma and adenocarcinoma. Conclusion Hepatoid adenocarcinoma of the stomach is a special type of gastric adenocarcinoma, and radical operation is the main treatment, but the prognosis of it is poor.
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.
Hepatoid adenocarcinoma (HAC) of the pancreas is a rare, highly malignant tumor with poor prognosis. This article presents the CT and MR features of HAC of the pancreas, while also reviewing the relevant literatures to succinctly summarize the underlying pathophysiological mechanism, imaging diagnosis, and differential diagnosis. The objective is to enhance the understanding of HAC of the pancreas among clinicians and radiologists.
