Abstract:
Objective To explore the clinicopathological and immunohistochemical features, diagnosis and treatment,prognosis of hepatoid adenocarcinoma of the stomach with neuroendocrine tumor.AFP, Syn, CgA, Ki-67, P53 were stained by immunohistochemistry and follow-up was conducted by telephone.Methods Hepatoid adenocarcinoma of the stomach with coexisting neuroendocrine tumor was identified in 13 cases from June 2004 to June 2014 in Ren Ji Hospital.Results Among the 13 cases of hepatoid adenocarcinoma of the stomach coexisting with neuroendocrine tumor patients, there were 7 males and 6 females, with an median age of 62 years.Tumors located in the gastric cardia in 2 cases, in the gastric antrum in 8 cases and in the gastric body in 3 cases.Tumor ranged from 1-19 cm.The follow-up rate was 100％.The median overall survival rate was 12 months, two patients died of liver metastasis and one patient died of anastomotic recurrence.Serum AFP increased in 10 patients with hepatoid adenocarcinoma of the stomach coexisted with neuroendocrine tumor.The structure consisted of hepatoid cell differentiation and adenocarcinoma differentiation and neuroendocrine differentiation area by histological microscope examination.Immunohistochemical staining showed that tumor regional AFP, Syn, CgA, Ki-67, P53 were positive.Conclusions Hepatoid adenocarcinoma of the stomach coexisting with neuroendocrine tumor is very rare, it is made up of three structures : hepatoid cell differentiation, adenocarcinoma differentiation and neuroendocrine differentiation area.Diagnosis relies on immunohistochemical and histological examination.
