The Epstein-Barr virus (EBV) is detected in about 10% of gastric carcinoma cases throughout the world. In EBV-associated gastric carcinoma, all tumor cells harbor the clonal EBV genome. Gastric carcinoma associated with EBV has distinct clinicopathological features, occurs predominately in men and in younger-aged individuals, and presents a generally diffuse histological type. Most cases of EBV-associated gastric carcinoma exhibit a histology rich in lymphocyte infiltration. The immunological reactiveness in the host may represent a relatively preferable prognosis in EBV-positive cases. This fact highlights the important role of EBV in the development of EBV-associated gastric carcinoma. We have clearly proved direct infection of human gastric epithelialcells by EBV. The infection was achieved by using a recombinant EBV. Promotion of growth by EBV infection was observed in the cells. Considerable data suggest that EBV may directly contribute to the development of EBV-associated GC. This tumor-promoting effect seems to involve multiple mechanisms, because EBV affects several host proteins and pathways that normally promote apoptosis and regulate cell proliferation.

A 55-year-old woman with non-small cell lung carcinoma complained of epigastric pain, bloating, anorexia and postprandial nausea and vomiting over a five-year period. An upper gastrointestinal pan-glucosamine contrast examination revealed a distinctive large, hook-shaped, ptotic gastric lumen with normal motility. The contrast agent demonstrated an abnormal round-trip flow anterior to the spine at the duodenal level, with pooling and gradual passage through this region in strands after prolonged retention.

Introduction: Given treatment landscape changes, understanding the prevalence of medical conditions/comorbidities influencing real-world unresectable hepatocellular carcinoma (uHCC) treatment decisions is key for improving outcomes.
Patients And Methods: In a retrospective chart review, physicians abstracted data from uHCC patients initiating first-line treatment (1L) between June 2020 and April 2022. Frequencies of medical conditions/comorbidities at 1L initiation were reported.

Background: Pathological regression grade after chemotherapy evaluated by surgically resected specimens is closely related with prognosis. Since usefulness of measuring the area of the residual tumor (ART) has been reported, this study aimed to evaluate the utility of ART in predicting the prognosis of patients with gastric cancer (GC) who received preoperative chemotherapy.
Methods: This single-center retrospective study examined the relationship between ART and survival outcomes.

Cancer, a complicated disease characterized by aberrant cellular metabolism, has emerged as a formidable global health challenge. Since the discovery of abnormal aldolase A (ALDOA) expression in liver cancer for the first time, its overexpression has been identified in numerous cancers, including colorectal cancer (CRC), breast cancer (BC), cervical adenocarcinoma (CAC), non-small cell lung cancer (NSCLC), gastric cancer (GC), hepatocellular carcinoma (HCC), pancreatic cancer adenocarcinoma (PDAC), and clear cell renal cell carcinoma (ccRCC). Moreover, ALDOA overexpression promotes cancer cell proliferation, invasion, migration, and drug resistance, and is closely related to poor prognosis of patients with cancer.
