Objective: To investigate the clinical characteristics,diagnosis and treatment of hepatoid adenocarcinoma of the stomach.
Methods: Clinical data of 13 hepatoid adenocarcinomas of the stomach, collected from 201 cases of gastric cancer, were analyzed retrospectively.
Results: Of the 201 gastric carcinomas, there were 13 AFP-producing adenocarcinomas of the stomach, the positive rate was 6.5%. Morphologically, the tumor cells formed glandular, medullary and linear structures. Of the 13 hepatoid adenocarcinomas of the stomach, 10 cases were in gastric antrum and 10 cases were poorly differentiated. The metastasis rates of liver and lymph node in hepatoid adenocarcinoma of stomach were higher than those in non-hepatoid adenocarcinoma of stomach. The treatment of hepatoid adenocarcinoma of stomach depended mainly on radical resection, and adjuvant chemotherapy was needed.The prognosis of hepatoid adenocarcinoma of stomach was poor.
Conclusion: Hepatoid adenocarcinoma of the stomach has its own special tumor biological behavior and poor prognosis. Special attention should be paid to this disease.

Hepatoid adenocarcinoma of the stomach (HAS) is a rare subtype of gastric cancer characterized by histological features resembling hepatocellular carcinoma. Surgical intervention remains the preferred treatment modality for eligible patients. However, the efficacy of neoadjuvant therapy and alternative treatment regimens has been found to be suboptimal.

Its histological characteristics are fetal gut-like architecture and tumor cells with cytoplasmic clearing, as well as positive immunohistochemical reaction to at least one of the enteroblastic markers. Hereby, we present a case of GAED with neuroendocrine marker positivity, with whole exome sequencing (WES), and an updated literature review.

Primary hepatoid adenocarcinoma (HAC) of the uterus is a particular tumour that bears high similarity to hepatocellular carcinoma histologically, and may easily be misdiagnosed because it is rare if you don' t remember it. In this report, we describe two cases of alpha-fetoprotein (AFP)-producing HAC of the uterus. Case 1 was a 69-year-old postmenopausal woman who was presented to the hospital for a medical examination.

Aims: Alpha-fetoprotein (AFP)-producing colorectal adenocarcinoma (AFPCRA) is uncommon, with obscure clinicopathological features and prognosis.
Methods And Results: In this retrospective comparison study on surgically resected colorectal adenocarcinomas (CRA, n = 2389), we investigated and compared clinicopathological and prognostic features between AFPCRA cases with elevated pre-operative serum AFP levels, as the AFPCRA study group (n = 49, 2.1%), and the exact sex-, age- and stage-matched CRA cases as the control group at a 1:2 ratio during the study period from 2011 to 2021.
