Article Abstract
Background: Preoperative chemotherapy for gastric cancer with obstructive symptoms traditionally requires bypass surgery.
Objective: To investigate the feasibility of preoperative enterostomy chemotherapy in patients with advanced gastric cancer who present with obstructive symptoms.
Methods: A total of 47 patients with cStage Ⅲ gastric cancer who underwent preoperative chemotherapy between April 2013 and May 2024 were included. Patients with circumferential lesions underwent enterostomy during diagnostic laparoscopy, which was followed by chemotherapy.
Results: The enterostomy and non-enterostomy groups included 20 and 27 patients, respectively. The chemotherapy regimens included SOX, SOX+nivolumab, SP, biweekly NAC-DCS, and XP+trastuzumab. Grade 3 or higher adverse events, including neutropenia, malaise, and diarrhea, were more common in the no-enterostomy group. The completion rates of at least 2 chemotherapy courses were similar between groups. Grade Ⅲa or higher complications during gastrectomy were slightly higher in the enterostomy group. The pathological responses were comparable between groups.
Conclusion: Preoperative chemotherapy using enterostomy for advanced gastric cancer with obstructive symptoms showed efficacy and safety comparable to those of traditional methods, suggesting that it is a viable treatment option.

Importance: Patients with advanced cancer frequently receive broad-spectrum antibiotics, but changing use patterns across the end-of-life trajectory remain poorly understood.
Objective: To describe the patterns of broad-spectrum antibiotic use across defined end-of-life intervals in patients with advanced cancer.
Design, Setting, And Participants: This nationwide, population-based, retrospective cohort study used data from the South Korean National Health Insurance Service database to examine broad-spectrum antibiotic use among patients with advanced cancer who died between July 1, 2002, and December 31, 2021.

S100 protein family members S100A8 and S100A9 function primarily as a heterodimer complex (S100A8/A9) in vivo. This complex has been implicated in various cancers, including gastric cancer (GC). Recent studies suggest that these proteins play significant roles in tumor progression, inflammation, and metastasis.

Aurora kinase A (AURKA) is a serine/threonine kinase that plays a critical role in cell cycle regulation, particularly during mitosis. Recent studies have identified AURKA as an oncogene overexpressed in various cancers, including gastric cancer (GC). This review summarizes the molecular mechanisms by which AURKA contributes to GC pathogenesis, including its roles in cell proliferation, apoptosis inhibition, epithelial-mesenchymal transition (EMT), and cancer stemness.

Helicobacter pylori was first characterized as an obligate bacterial pathogen in 1983. Since then, substantial advances have been made in understanding the pathophysiology of H. pylori infection, optimizing diagnostic and therapeutic strategies, and expanding testing and treatment-including in the prevention of gastric malignancies.

Introduction: Patients with chronic kidney disease (CKD) face unique challenges in cancer treatment, including the need for chemotherapy dose adjustments and avoiding nephrotoxic agents, often leading to less aggressive treatment. However, little is known about the real-world administration of adjuvant chemotherapy for patients with CKD. In this study, we aimed to investigate the prevalence of adjuvant chemotherapy in patients with CKD and to explore factors influencing chemotherapy use.
