目的
检测乳腺癌患者外周血中β2 微球蛋白(β2-MG)、癌胚抗原(CEA)、CA153、CA125 水平,以探讨外周血β2-MG、CEA、CA153、CA125 在乳腺癌临床实践中的作用。
方法
对140 例乳腺癌患者及144 例健康体检者应用免疫散射比浊法检测外周血β2-MG,用化学发光法检测外周血CEA、CA153、CA125 的水平,数据统计用Kruskal-Wallis 检验、Chi-square 检验和Wilcoxon 秩和检验。
结果
乳腺癌患者外周血β2-MG 和CEA 的检测值分别为1.8 (1.5 ~2.2) mg/L 和1.7(1.2 ~2.4) ng/ml,高于健康对照组[1.5(1.3 ~1.8)mg/L,1.2(0.9 ~1.9)ng/ml,P<0.05],且阳性率高于健康人群(P<0.05);以β2-MG 检测为基础,联合检测未增加诊断的敏感性(P>0.05);以临床分期为参照指标, CA153 在Ⅲ期患者的检测值明显高于Ⅰ期和Ⅱ期患者(P<0.05)。乳腺癌患者术后β2-MG、CEA、CA153 检测均有下降,与术前相比差异有统计学意义(P<0.05)。
结论
以β2-MG 为基础的联合诊断对乳腺癌诊断敏感性未见明显增加;血清CA153 检测水平对乳腺癌预后有一定的预测作用;β2-MG、CEA 和CA153 对乳腺癌术后随访有一定临床意义。

Objective
To detect the levels of serum tumor marker β2-microglobulin(β2-MG), CEA, CA153 and CA125 so as to evaluate their clinical significance in clinical treatment of breast cancer.
Methods
The β2-MG level in peripheral blood was detected by nephelometry and the CEA, CA153 and CA125 levels in peripheral blood were determined by chemiluminescence method. Statistical analysis was performed using Kruskal-Wallis test,Chi-square test or Wilcoxon test.
Results
The β2-MG and CEA levels in peripheral blood were 1.8 (1.5-2.2) mg/L and 1.7(1.2-2.4) ng/ml in breast cancer patients respectively,which were higher than those of healthy controls[(1.5(1.3-1.8) mg/L,1.2(0.9-1.9) ng/ml,P<0.05]. The positive rate in breast cancer patients was higher than that in healthy control.On the basis of β2-MG test,combined tests of more than one tumor marker could not increase the sensitivity (P>0.05). According to clinical-pathologic stage, the CA153 level was statistically higher in stage Ⅲpatients than that in stage Ⅰor Ⅱ(P<0.05);After operation,the β2-MG, CEA and CA153 levels in peripheral blood in breast cancer patients were significantly lower than the preoperative levels (P<0.05).
Conclusions
Based on the level of β2-MG in peripheral blood, combined test cannot increase the sensitivity of diagnosis. The CA153 level may be useful in predicting the prognosis. There are significant differences in the levels of tumor markers between preoperative and postoperative breast cancer patients, which imply the importance of tumor markers in follow-up.
