摘要:

目的:探究患者外周血淋巴细胞亚群水平及血清胃蛋白酶原PG ⅠPG Ⅱ)、胃泌素-17G-17)、幽门螺杆菌(HP)抗体检测在胃癌筛查及诊断中的临床应用。方法:本研究选取158名对象,来自于20182020年本地区1 326名经临床指标危险分层评估、胃镜及病理学诊断筛查后胃癌高危患者。根据胃镜检查及病理结果分为3组,胃癌组22例、瘤变组29例、胃炎组107例。流式细胞术检测受试者外周血T淋巴细胞亚群(CD4+TCD8+T)及CD4+T/CD8+TB淋巴细胞(CD3-CD19+)、NK细胞(CD3-CD16+CD56+)水平;荧光免疫层析技术测定血清PG ⅠPG ⅡG-17,计算PG Ⅰ/PG Ⅱ比值(PGR);胶体金方法检测HP抗体,分析组间差异。结果:卡方及方差分析结果发现:HP抗体、CD4+TCD8+TCD4+T/CD8+TB细胞、PG IIPGR及年龄在多组间存在显著差异,均具有统计学意义(P<0.05);胃癌组CD8+T高于其他两组,CD4+TCD4+T/CD8+TPGR低于其他两组,有统计学意义(P<0.05);多元Logistic回归分析显示:年龄和HP抗体与胃癌组相关(P<0.05)。ROC曲线分析胃癌诊断效能显示:多项指标联合检测AUC0.896,均高于各项指标独立检测效能。结论:联合检测患者外周血淋巴细胞亚群及胃功能血清学指标,对胃癌患病风险评估及诊断具有较高的临床价值,对高危人群的筛查具有重要临床价值。

Abstract:

Objective: Exploring the clinical relevance of peripheral blood lymphocyte subsets serum gastric protease markers PG Ⅰ PG Ⅱ), gastrin-17 G-17), and Helicobacter pylori HP antibodies in gastric cancer screening and diagnosis.Methods: We select 158 subjects from 1326 high-risk outpatients and inpatients who undergo gastric cancer screening through clinical risk stratification assessment endoscopy and pathological biopsy conducted from 2018 to 2020 in the local region. These subjects are classified into three groups based on gastroscopic examination and histopathological evaluation the gastric cancer group with 22 cases the precancerous lesion group with 29 cases and the gastritis group with 107 cases. Flow cytometry is employed to analyze peripheral blood T lymphocyte subsets CD4+T CD8+T and CD4+T/CD8+T B lymphocytes CD3-CD19+), and NK cells CD3-CD16+CD56+. Fluorescence immunochromatography is utilized to measure serum levels of PG I PG II and G-17 as well as to calculate PGR. HP antibodies are detected using the colloidal gold immunoassay method.Results: The statistical results of chi-square and analysis of variance reveal significant differences among multiple groups for HP antibodies CD4+T CD8+T CD4+T/CD8+T B PG II PGR and age all of which exhibit statistical significance P<0.05. In the gastric cancer group CD8+T levels are higher compared to the other groups while CD4+T CD4+T/CD8+T PGR and age are lower than in the other groups demonstrating statistical significance P<0.05. Multivariate logistic regression analysis indicates that age and HP antibodies are significantly associated with the gastric cancer group P<0.05. ROC curve analysis for gastric cancer diagnosis shows that the combined detection of multiple biomarkers yields an AUC of 0.896 which exceeds the diagnostic performance of each individual biomarker.Conclusion: The combined detection of peripheral blood lymphocyte subsets and gastric function serological markers demonstrates significant clinical value for the risk assessment and diagnosis of gastric cancer suggesting its potential for application and clinically valuable for high-risk population screening.
