Abstract
Objective: To evaluate the predictive potential of serum exosomal microRNAs (miRNAs) and traditional serological biomarkers for lymph node metastasis in gastric cancer and to assess their applicability in clinical practice.
Methods: This retrospective study included 845 gastric cancer patients treated between January 2020 and December 2023, as the training cohort. Patients were stratified into lymph node-positive (n = 231) and lymph node-negative (n = 614) groups based on postoperative pathological evaluation. Serum exosomal miRNAs and conventional serological biomarkers were quantified and compared between groups. Multivariate logistic regression analysis was conducted to identify independent predictors. Model performance was validated using an independent test cohort comprising 277 patients (74 lymph node-positive, 203 lymph node-negative).
Results: Patients with lymph node metastasis exhibited significantly elevated expression of miR-21, miR-20a, miR-27a, and miR-106a. Serological markers that were significantly higher in the lymph node positive group included carbohydrate antigen 724, carcinoembryonic antigen, hepatocyte growth factor, vascular endothelial growth factor, interleukin-6, and circulating cell-free DNA (all P < 0.05). A combined predictive model integrating both miRNA and serological data demonstrated strong diagnostic performance, with an area under the curve of 0.816 in the training cohort and 0.817 in the validation cohort.
Conclusion: Serum exosomal miRNAs and serological biomarkers are significantly associated with lymph node metastasis in gastric cancer.
期刊介绍:
The American Journal of Cancer Research (AJCR) (ISSN 2156-6976), is an independent open access, online only journal to facilitate rapid dissemination of novel discoveries in basic science and treatment of cancer. It was founded by a group of scientists for cancer research and clinical academic oncologists from around the world, who are devoted to the promotion and advancement of our understanding of the cancer and its treatment. The scope of AJCR is intended to encompass that of multi-disciplinary researchers from any scientific discipline where the primary focus of the research is to increase and integrate knowledge about etiology and molecular mechanisms of carcinogenesis with the ultimate aim of advancing the cure and prevention of this increasingly devastating disease. To achieve these aims AJCR will publish review articles, original articles and new techniques in cancer research and therapy. It will also publish hypothesis, case reports and letter to the editor. Unlike most other open access online journals, AJCR will keep most of the traditional features of paper print that we are all familiar with, such as continuous volume, issue numbers, as well as continuous page numbers to retain our comfortable familiarity towards an academic journal.
