摘要:

目的 探讨血清可溶性B7同源体3(sB7-H3)、高尔基体蛋白73(gp73)和肿瘤相关胰蛋白酶原-2(TAT-2)联合检测在结直肠癌和管状腺瘤鉴别诊断中的价值。方法 选取2020年12月—2022年12月邯郸市第一医院结直肠癌患者86例(结直肠癌组)、管状腺瘤患者86例(管状腺瘤组)和健康体检者86名(正常对照组)。依据TNM分期将结直肠癌患者分为Ⅰ~Ⅱ期组(54例)和Ⅲ~Ⅳ期组(32例)。检测所有研究对象血清sB7-H3、gp73、TAT-2、癌胚抗原(CEA)、糖类抗原19-9(CA19-9)水平和粪便隐血情况。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鉴别诊断结直肠癌和管状腺瘤的效能。采用多因素Logistic回归分析评估结直肠癌发生的影响因素。结果 正常对照组、管状腺瘤组、结直肠癌组血清sB7-H3、gp73、TAT-2、CEA、CA19-9水平和粪便隐血阳性所占比例依次升高(P<0.001)。Ⅲ~Ⅳ期组血清sB7-H3、gp73、TAT-2、CEA、CA19-9水平均显著高于Ⅰ~Ⅱ期组(P<0.05)。 粪便隐血阳性和CEA、CA19-9、sB7-H3、gp73、TAT-2升高均是结直肠癌发生的危险因素(P<0.05)。血清CEA、CA19-9、sB7-H3、gp73、TAT-2单项检测和sB7-H3、gp73、TAT-2联合检测区分正常对照和管状腺瘤的曲线下面积(AUC)分别为0.701、0.710、0.751、0.754、0.829、0.904,区分正常对照和结直肠癌的AUC分别为0.781、0.758、0.809、0.780、0.798、0.900,鉴别诊断结直肠癌和管状腺瘤的AUC分别为0.701、0.718、0.730、0.739、0.710、0.908。结论 血清sB7-H3、gp73和TAT-2联合检测可作为结直肠癌和管状腺瘤鉴别诊断的指标。

Abstract:

Objective To investigate the role of combined determination of serum soluble B7-homologue 3(sB7-H3),Golgi protein 73(gp73) and tumor-associated trypsinogen-2(TAT-2) in the differential diagnosis of colorectal cancer and tubular adenoma. Methods A total of 86 patients with colorectal cancer(colorectal cancer group),86 patients with tubular adenoma(tubular adenoma group) and 86 healthy subjects(healthy control group) were enrolled from the First Hospital of Handan City from December 2020 to December 2022. The colorectal cancer patients were classified into stage Ⅰ-Ⅱ group(54 cases) and stage Ⅲ-Ⅳ group(32 cases) according to TNM staging. Serum levels of sB7-H3,gp73,TAT-2,carcinoembryonic antigen(CEA) and carbohydrate antigen 19-9(CA19-9) and fecal occult blood status were determined. The efficacy of single and combined determinations of each indicator in differentiating colorectal cancer and tubular adenoma was evaluated using receiver operating characteristic(ROC) curve. Multivariate Logistic regression analysis was used to assess the influencing factors of colorectal cancer occurrence. Results The serum levels of sB7-H3,gp73,TAT-2,CEA and CA19-9 and the proportion of positive fecal occult blood in healthy control group,tubular adenoma group and colorectal cancer group were increased successively(P<0.001). The serum levels of sB7-H3,gp73,TAT-2,CEA and CA19-9 in stage Ⅲ-Ⅳ group were higher than those in stage Ⅰ-Ⅱ group(P<0.05). Positive fecal occult blood and elevated CEA,CA19-9,sB7-H3,gp73 and TAT-2 were risk factors for colorectal cancer occurrence(P<0.05). The areas under curves(AUC) for differentiating healthy control from tubular adenoma and differentiating healthy control from colorectal cancer by single determinations of serum CEA,CA19-9,sB7-H3,gp73 and TAT-2 and their combined determination were 0.701,0.710,0.751,0.754,0.829,0.904,and 0.781,0.758,0.809,0.780,0.798 and 0.900,respectively. The AUC for differentiating colorectal cancer and tubular adenoma were 0.701,0.718,0.730,0.739,0.710 and 0.908,respectively. Conclusions The combined determination of serum sB7-H3,gp73 and TAT-2 can be used as indicators for the differential diagnosis of colorectal cancer and tubular adenoma.
