摘要: 目的 通过检测结直肠癌患者血清及组织中癌胚抗原(CEA)及β2微球蛋白(β2MG)的表达,探讨结合两者在结直肠癌诊断中的作用。方法 对30例结直肠癌患者的血清、癌组织和癌旁组织进行CEA及β2MG检测,设置对照组为行肠镜检查的正常健康体检者30例。分别对比CEA及β2MG在结直肠癌中的关系,进一步对比CEA及β2MG两者在结直肠癌在结直肠癌患者中的肿瘤大小、分期、浸润深度及转移的关系。 同时对结直肠癌及健康体检者的一般情况如性别、年龄、CEA、β2MG、血红蛋白及白蛋白进行对比,以进一步了解CEA及β2MG 在结直肠癌中的重要性。结果 CEA在结直肠癌患者癌组织、癌旁组织及血清中升高的比例为100%、10%、47%;β2MG在结直肠癌患者癌组织、癌旁组织及血清升高的比例为60%、57%、23%;联合血清中CEA及β2MG升高的比例为63%;正常对照组中的CEA升高的比例为33%,β2MG升高的比例为67%;无论CEA还是β2MG在结直肠癌中均有一定比例的升高,联合两者升高更明显。结论 CEA及β2MG是恶性肿瘤特别是结直肠癌的重要指标,联合两者的检测提高结直肠癌的早期诊断。

Abstract: Objective To detect the expression of carcinoembryonic antigen and β2 microglobulin in serum and tissue of patients with colorectal cancer, and to explore their roles in the diagnosis of colorectal cancer. Methods 30 patients with colorectal cancer were examined for CEA and β2MG in serum, cancer and para-cancer tissues, and 30 healthy persons with normal colonoscopy were selected as the control group. The expressions of CEA and β2MG in serum and tissues were compared, and the relationship between CEA and β2MG and tumor size, stage, depth of invasion and metastasis were analyzed. Results The increased in proportion of CEA in cancer tissue、para-carcinoma tissue and serum of colorectal cancer was 100%、10%、47%; Similarly, the increased in proportion of β2MG was 60%、57%、23%;Combined calculation the increased in proportion ofCEA and β2MG in serum of colorectal cancer was 63%;In the normal control, the increased in proportion of CEA was 33%;The increased in proportion of β2MG was 67%.Both CEA and β2MG in colorectal cancer had a certain proportion, the rise of joint both was obviously more. Conclusion CEA and β2MG are important markers of malignancy, especially colorectal cancer. Combined detection of CEA and β2MG can improve the early diagnosis of colorectal cancer.
