摘要:

目的 探讨磷酸化应激诱导蛋白1(STIP1)和甲胎蛋白异质体(AFP-L3)在肝细胞肝癌(HCC)诊断中的临床价值。方法 选取2023年8月—2024年6月首都医科大学附属北京佑安医院HCC患者88例(HCC组)、乙型肝炎患者34例(乙型肝炎组)、肝硬化患者33例(肝硬化组)、健康体检者26名(正常对照组)。另选取2024年10月首都医科大学附属北京佑安医院HCC患者17例、非HCC患者33例(包括乙型肝炎患者15例、肝硬化患者11例、健康体检者7名)作为验证集。检测所有研究对象血清STIP1、甲胎蛋白(AFP)、AFP-L3百分比、丙氨酸氨基转移酶(ALT)、天门冬氨酸氨基转移酶(AST)、总胆红素(TB)、直接胆红素(DBil)、总蛋白(TP)、白蛋白(Alb)、γ-谷氨酰基转移酶(GGT)、乙型肝炎表面抗原(HBsAg)。采用Spearman相关分析评估STIP1和AFP-L3百分比的相关性。采用受试者工作特征(ROC)曲线评价各项指标单项检测和联合检测诊断HCC的效能。采用Logistic回归分析评估HCC发生的影响因素。结果 HCC组ALT、AST、GGT、STIP1、AFP、AFP-L3百分比显著高于乙型肝炎组、肝硬化组和正常对照组(P<0.001)。年龄、STIP1、AFP-L3百分比是HCC发生的独立危险因素[比值比(OR)值分别为1.111、1.015、1.036,95%可信区间(CI)分别为1.052~1.173、1.008~1.021、1.000~1.073,P<0.05]。STIP1与AFP-L3百分比呈正相关(r=0.493,P<0.001)。血清STIP1、AFP-L3百分比单项检测和联合检测诊断HCC的曲线下面积(AUC)分别为0.870、0.760和0.897。在验证集中,联合检测模型的正确率为94.00%,敏感性为88.23%,特异性为96.97%。结论 STIP1和AFP-L3百分比与HCC发生密切相关,二者联合检测可显著提高HCC诊断的效能。STIP1和AFP-L3百分比可作为HCC新的诊断生物标志物。

Abstract:

Objective To investigate the clinical roles of stress-induced phosphoprotein 1(STIP1) and alpha-fetoprotein-heterogeneity(AFP-L3) in the diagnosis of hepatocellular carcinoma(HCC).Methods From Beijing Youan Hospital of Capital Medical University,between August 2023 and June 2024,88 HCC patients(HCC group),34 hepatitis B patients(hepatitis B group),33 liver cirrhosis patients(liver cirrhosis group) and 26 healthy subjects(healthy control group) were enrolled. An additional validation cohort was established in October 2024,consisting of 17 HCC patients and 33 non-HCC patients(including 15 hepatitis B cases,11 liver cirrhosis cases and 7 healthy subjects). Serum levels of STIP1,alpha-fetoprotein(AFP),AFP-L3 percentage,alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TB),direct bilirubin(DBil),total protein(TP),albumin(Alb),gamma-glutamyltransferase(GGT) and hepatitis B surface antigen(HBsAg) were determined. Spearman correlation analysis was used to evaluate the relationship between STIP1 and AFP-L3 percentage,receiver operating characteristic(ROC) curve was used to assess the diagnostic performance of single and combined determinations for HCC,and Logistic regression analysis was used to identify independent risk factors for HCC.Results The HCC group demonstrated elevated levels of ALT,AST,GGT,STIP1,AFP and AFP-L3 percentage compared to hepatitis B,liver cirrhosis and healthy control groups(P<0.001). Age,STIP1 and AFP-L3 percentage were independent risk factors for HCC [odds ratios(OR) were 1.111,1.015 and 1.036,95% confidence intervals(CI) were 1.052-1.173,1.008-1.021 and 1.000-1.073,respectively,P<0.05]. A positive correlation was observed between STIP1 and AFP-L3 percentage(r=0.493,P<0.001). The areas under curves(AUC) of STIP1,AFP-L3 percentage single and combined determinations in HCC diagnosis were 0.870,0.760 and 0.897,respectively. In the validation cohort,the combined determination model demonstrated superior diagnostic performance with the accuracy of 94.00%,the sensitivity of 88.23% and the specificity of 96.97%.Conclusions STIP1 and AFP-L3 percentage show associations with HCC. The combined determination enhances the diagnostic performance for HCC,suggesting their potential as valuable biomarkers in HCC diagnosis.
