The development of parakeratotic lesions and ulcers of the oesophagogastric epithelium was studied in pigs from a variety of sources and of ages ranging from 10 to 22 weeks. In general, the severity, as assessed by gross appearance, paralleled the depth to which parakeratotic change extended into the epithelium. However, some early degenerative change and erosion was observed in epithelium graded as macroscopically normal. Separation and erosion usually occurred beneath a band of epithelial cells with cytoplasmic pallor and nuclear degeneration underlying the parakeratotic layers. These findings are discussed in relation to the possible role of diet and gastric acidity in the pathogenesis of the lesions.

Updated Review of Proximal Gastrectomy for Gastric Cancer or Cancer of the Gastroesophageal Junction.
J Gastric Cancer
January 2025
Department of Gastroenterological Surgery, Cancer Institute Hospital Ariake, Tokyo, Japan.
Proximal gastrectomy (PG) has reemerged as a viable surgical option for managing proximal gastric cancer and gastroesophageal junction cancer, particularly for early-stage tumors, offering potential advantages over total gastrectomy (TG). This review examines the evolution of PG, emphasizing surgical techniques and outcomes. Although PG was initially abandoned due to postoperative complications such as reflux esophagitis, advances in reconstruction methods, such as the double-flap technique and double-tract reconstruction, have significantly improved patient quality of life and reduced complications.

Background: Despite approvals of new first-line immunotherapies for advanced/metastatic gastric cancer/gastroesophageal junction cancer (aGC/GEJC), patients' median survival is around 14 months and their health-related quality of life (HRQoL) is affected by disease-related symptoms and treatment-related side effects. Using a targeted literature review (TLR) and patient interviews, this study identified disease- and treatment-related concepts that are important to patients with aGC/GEJC and their HRQoL.
Methods: A TLR was conducted to identify primary qualitative studies from 2018 to 2021 on patients' experiences with aGC/GEJC.

Background: The delivery of cancer services changed significantly during the COVID-19 pandemic. This study aimed to describe changes in presentations, assess the change in recommendations by the MDT during the pandemic, and describe the subsequent long-term impact of these changes on survival rates in patients with EG cancer.
Methods: A retrospective cohort study was designed comparing three patient groups of those referred to EG MDT in the same 6-month period pre-pandemic (PP;2019) during the initial phase of the pandemic (P1;2020) and the year after the initial phase (P2;2021).
Occult collision tumor of the gastroesophageal junction comprising adenocarcinomas with distinct molecular profiles.

Collision tumors, characterized by the coexistence of two unique neoplasms in close approximation, are rare and pose diagnostic challenges. This is particularly true when the unique neoplasms are of the same histologic type. Here we report such a case where comprehensive tumor profiling by next generation sequencing (NGS) as well as immunohistochemistry revealed two independent adenocarcinomas comprising what was initially diagnosed as a single adenocarcinoma of the gastroesophageal (GEJ) junction.

Background: Esophageal cancer (EC) is a disease with a poor prognosis. While treatment options have been improved, there is no consensus for surveillance strategies following therapy with curative intent. As the incidence of EC is rising and a large fraction of patients will experience disease recurrence, the need for evidence-based treatment and optimal surveillance is evident.
