Hepatoid adenocarcinoma of the stomach is an uncommon gastric tumor. A throughout search of the literature revealed only 86 cases: the first case was reported by Bourreille et al in 1970. We describe a patient with primary gastric adenocarcinoma with high serum alpha-fetoprotein (AFP) levels (7000 ng/ml). Histologically foci strongly resembling hepatocellular carcinoma with hyaline globules were noted. Immunoreactivity for alpha-fetoprotein (AFP), a1 antitrypsin and CEA also indicate hepatocellular differentiation. This case provides informations on the DNA content and Ki67 expression of this unusual and aggressive variant of gastric adenocarcinoma.

Background: The COVID-19 pandemic has overloaded healthcare systems worldwide. Other diseases, such as neoplasms, including gastric cancer, remained prevalent and had their treatment compromised.
Aims: The aim of this study was to evaluate the impact of the COVID-19 pandemic on the treatment of gastric cancer and adherence to the recommended preoperative COVID-19 screening protocol.

Introduction: Primary squamous cell carcinoma (SCC) is a rare type of pancreatic cancer with an extremely low incidence rate and a prognosis that is poorer than that of pancreatic ductal adenocarcinoma.
Presentation Of Case: We report a case of pure pancreatic SCC in an 80-year-old man. Based on the examination before surgical resection, we did not detect any SCC lesions that might have metastasized to the pancreas.

Delta-like protein (DLL3) is a novel therapeutic target. DLL3 expression in gastroenteropancreatic neuroendocrine tumors (GEP-NECs) is poorly understood, complicating the distinction between well-differentiated neuroendocrine tumors G3 (NET G3) and poorly differentiated NEC. DLL3 immunohistochemistry (IHC) was performed on 248 primary GEP-NECs, correlating with clinicopathological parameters, NE markers, PD-L1, Ki67 index, and prognosis.

Activation of the p38 mitogen-activated protein kinase (MAPK) pathways is vital in regulating cell growth, differentiation, apoptosis, and stress response, significantly affecting tumorigenesis and cancer progression. We developed a bioinformatic technique to construct an interactome network-based molecular pathways for genes of interest and quantify their activation levels using high-throughput gene expression data. This study is focused on the p38α, p38β, p38γ, and p38δ kinases, examining their activation levels (PALs) based on transcriptomic data and their associations with survival and drug responsiveness across various cancer types.

Trousseau's syndrome is a thromboembolic disorder associated with malignancies, with cerebral infarction and hemorrhage representing common central nervous system complications in patients with cancer. This report details the diagnosis and treatment of a patient with gastric adenocarcinoma at our institution who concurrently developed cerebral infarction and subarachnoid hemorrhage. We performed a comprehensive literature review in the Wanfang and PubMed databases, searching for relevant studies on Trousseau's syndrome, cerebral embolism, and subarachnoid hemorrhage.
