摘要:

目的 探讨血清人表皮生长因子受体2(HER-2)和分化抗原簇44(CD44)水平在结直肠癌中的临床价值。方法 采用酶联免疫吸附试验检测38例结直肠癌患者(结直肠癌组)术前及术后2~3 d、35例结直肠良性病变患者(良性病变组)和36名健康体检者(正常对照组)的血清HER-2和CD44水平。收集所有对象的一般资料。采用Pearson相关分析评估HER-2与CD44的相关性。采用受试者工作特征(ROC)曲线评估各项指标单项检测及联合检测辅助诊断结直肠癌的效能。结果 结直肠癌组术前血清HER-2水平高于良性病变组和正常对照组(P<0.05、P<0.000 1)。结直肠癌组术前血清CD44水平高于正常对照组(P<0.05),与良性病变组差异无统计学意义(P>0.05)。血清HER-2水平与结直肠癌患者RAS基因突变及周围神经侵犯有关(P<0.05),CD44水平与Ras基因突变及周围神经侵犯无关(P>0.05);血清HER-2及CD44水平与年龄、性别、肿瘤类型、肿瘤大小、TNM分期、淋巴结转移及脉管侵犯均无关(P>0.05)。ROC曲线分析结果显示,HER-2、CD44、癌胚抗原(CEA)、糖类抗原(CA19)-9单项检测及联合检测诊断结直肠癌的曲线下面积(AUC)分别为0.779、0.692、0.620、0.634及0.837。结直肠癌患者术后血清CD44水平显著低于手术前(P<0.000 1),而血清HER-2水平术前、术后差异无统计学意义(P>0.05)。 结论 结直肠癌患者HER-2与CD44显著相关,二者联合检测或可用于结直肠癌的辅助诊断及疗效评估。

Abstract:

Objective To investigate the roles of serum human epidermal growth factor receptor-2(HER-2)and cluster of differentiation 44(CD44) in patients with colorectal cancer. Methods The levels of serum HER-2 and CD44 were determined by enzyme-linked immunosorbent assay in 38 colorectal cancer patients before and 2-3 d after operation,35 patients with benign colorectal diseases(benign disease group) and 36 healthy subjects(healthy control group). The general data of all the subjects were collected. The correlation between serum HER-2 and CD44 levels in colorectal cancer patients was analyzed by Pearson correlation analysis. The efficiencies of each marker and combined determination in the auxiliary diagnosis of colorectal cancer were evaluated by receiver operating characteristic(ROC) curve. Results The preoperative serum HER-2 levels in colorectal cancer group were higher than those in benign colorectal disease and healthy control groups(P<0.05,P<0.000 1). The preoperative serum CD44 levels in colorectal cancer group were higher than those in healthy control group(P<0.05). Serum CD44 levels between colorectal cancer and benign colorectal disease group had no statistical significance(P>0.05). The levels of serum HER-2 in colorectal cancer group were closely related to Ras mutation and peripheral nerve invasion(P<0.05),and they were not related to serum CD44 levels(P>0.05). Serum HER-2 and CD44 levels were not related to age,sex,tumor type,tumor size,TNM stage,lymph node metastasis and vascular invasion(P>0.05). According to the results of ROC curve analysis,the areas under curves(AUC) of HER-2,CD44,carcinoembryonic antigen(CEA),carbohydrate antigen 19-9(CA19-9) determinations and the combined determination in colorectal cancer diagnosis were 0.779,0.692,0.620,0.634 and 0.837,respectively. Postoperative levels of serum CD44 were reduced compared to preoperative levels in colorectal cancer group(P<0.000 1),whereas no statistical significance was observed in serum HER-2 levels before and after operation(P>0.05). Conclusions Serum HER-2 and CD44 levels are correlated in colorectal cancer patients. The combined determination of them may play a role in colorectal cancer auxiliary diagnosis and therapeutic monitoring.
