Antralization is considered a critical, reversible stage preceding gastric cancer. However, available biomarkers for identifying antralization are lacking. This study aimed to explore antralization-specific biomarkers in peripheral blood and gastric mucosa.
In this prospective cohort study, adult patients presenting with upper gastrointestinal symptoms were enrolled and categorized into antralization and non-antralization groups based on pathological examination of gastric mucosa. Helicobacter pylori (H. pylori) infection was detected using the 13 C-urea breath test, rapid urease test, and/or H. pylori serological test. Blood samples and gastric biopsies were collected for biomarker analysis.
Of the 92 patients studied, 42 (45.7%) were diagnosed with H. pylori infection and 61 (66.3%) with antralization. The rate of H. pylori infection and the incidence of acid reflux were higher in the antralization group than in the non-antralization group (both P < 0.05). Patients with antralization had higher plasma lymphocyte counts and lower serum levels of lipopolysaccharide (both P < 0.05). The positive rates and intensity of trefoil factor-2 and mucin (MUC) 6 expression were higher, whereas the positive rate and intensity of MUC5AC expression were lower in the incisura and body mucosa with antralization compared with those without antralization (all P < 0.05). Additionally, the intensity of MUC5B expression was higher in the gastric body mucosa with antralization than in those without antralization ( P < 0.05).
Increased lymphocyte counts, decreased serum LPS levels, increased expression of TFF2, MUC6, and MUC5B, and decreased expression of MUC5AC in proximal gastric mucosa appear to be antralization-specific. In addition, acid reflux is closely associated with antralization. Further studies evaluating additional hematological and molecular markers and their diagnostic performance for antralization are warranted.

The study was recently published in the Cancer Screening and Prevention .
Cancer Screening and Prevention (CSP) publishes high-quality research and review articles related to cancer screening and prevention. It aims to provide a platform for studies that develop innovative and creative strategies and precise models for screening, early detection, and prevention of various cancers. Studies on the integration of precision cancer prevention multiomics where cancer screening, early detection and prevention regimens can precisely reflect the risk of cancer from dissected genomic and environmental parameters are particularly welcome.
