Background: Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) drives tumorigenesis of various human cancers. However, the association between MALAT1 variants and gastric cancer (GC) risk is unknown. We performed a case-control study to evaluate the possible association between rs619586 and rs3200401 SNPs in MALAT and GC risk.
Methods: Samples from 458 patients with GC and 381 controls were genotyped using the TaqMan genotyping assay.
Results: In stratified analyses, we observed that rs3200401 CT in the codominant model and CT+TT in the dominant model were associated with increased GC risk in male patients (CT: odds ratio [OR] = 1.81, 95% confidence interval [CI] = 1.09-3.01, p = 0.022; CT+TT: OR = 1.74, 95% CI = 1.07-2.83, p = 0.026), and the differentiated (CT: OR =1.79, 95% CI = 1.18-2.73, p = 0.007; CT+TT: OR = 1.76, 95% CI = 1.17-2.64, p = 0.007), and intestinal (CT: OR = 1.67, 95% CI = 1.11-2.49, p = 0.013; CT+TT: OR = 1.68, 95% CI = 1.14-2.47, p = 0.009) GC subgroups.
Conclusion: MALAT1 rs3200401 increases GC susceptibility and might affect GC development. Further studies are needed to validate our results in large populations and different ethnic groups.

Introduction: Gastric cancer (GC) is a leading cause of cancer-related deaths worldwide, with delayed diagnosis often limiting effective treatment options. This study introduces a novel, non-invasive radiomics-based approach utilizing [18F] FDG PET/CT to predict VEGF status and survival in GC patients. The ability to non-invasively assess these parameters can significantly influence therapeutic decisions and outcomes.

Background And Aims: Oral microbiota may contribute to the development of upper gastrointestinal (UGI) disorders. We aimed to study the association between the microbiome of saliva, subgingival and buccal mucosa, and UGI disorders, particularly precancerous lesions. We also aimed to determine which oral site might serve as the most effective biomarker for UGI disorders.

Background: The demand for frailty care is continuously increasing in hospitalized tumor patients with the aging of the population. Nurses are the primary care providers of hospitalized tumor patients with frailty but research on exploring their behavior and associated factors is limited. This study aims to describe the current situation of frailty care behaviors in oncology nurses and to explore the factors influencing frailty care behaviors.

Background: Laparoscopic gastrectomy lacks hand-direct tactile sense and has a limited surgical field compared to laparotomy. Apart from textbook classification, there are anatomical variations in the gastric arteries. Laparoscopic gastrectomy presents technical difficulties and necessitates a more comprehensive comprehension of regional anatomy than open surgical procedures.
