【摘要】 目的:探討肠腺癌肿瘤组织中CK7、CK20、CEA、Ki-67表达水平与其临床病理特征的关系。方法:选取2015年1月-2017年3月于本院确诊并进行治疗的肠癌患者139例,均采用免疫组织化学染色Envision法检测其肠腺癌组织中CK7、CK20、CEA、Ki-67表达水平。结果:患者CK7、CK20、CEA表达阳性率分别为10.79%(15/139)、90.65%(126/139)、90.65%(126/139),Ki-67的增殖指数为(61±22)%;CK7的表达在不同部位及淋巴结转移间比较差异均有统计学意义(P<0.05);CK20的表达在不同部位、肿瘤大小、组织学类型及临床分期之间比较差异均有统计学意义(P<0.05);CEA的表达在不同组织学类型及淋巴结转移间比较差异均有统计学意义(P<0.05);Ki-67的表达在组织学类型、临床分期之间比较差异均有统计学意义(P<0.05)。结论:CK7、CK20表达情况有助于腺癌来源部位的判断;CK7、CEA阳性表达者,其淋巴结转移能力更强;CK20可能促进腺癌细胞分化,CEA则可能阻碍细胞分化;Ki-67的增殖活性与肿瘤的低分化程度及高临床分期相关。

【Abstract】 Objective:To investigate the relationship between the expression level of CK7,CK20,CEA,Ki-67 in intestinal adenocarcinoma and its clinicopathological features.Method:A total of 139 patients with colorectal cancer diagnosed and treated in our hospital from January 2015 to March 2017 were selected.The expression levels of CK7,CK20,CEA and Ki-67 in intestinal adenocarcinoma were detected by immunohistochemical staining and Envision.Result:The positive rates of CK7,CK20 and CEA were 10.79%(15/139),90.65%(126/139) and 90.65%(126/139) respectively,and the proliferation index of Ki-67 was(61±22)%.The expression of CK7 in different locations and lymph node metastases were compared,the differences were statistically significant(P<0.05).The expression of CK20 in different locations,tumor size,histological type and clinical stage were compared,the differences were statistically significant(P<0.05).The expression of CEA in different histological types and lymph node metastasis were compared,the differences were statistically significant(P<0.05).The expression of Ki-67 in histological type and clinical stage were compared,the differences were statistically significant(P<0.05).Conclusion:The expression of CK7 and CK20 are helpful to the prediction of the origin of adenocarcinoma,and the positive expression of CK7 and CEA has stronger lymph node metastasis.CK20 may promote differentiation of adenocarcinoma cells,while CEA may block cell differentiation,and the proliferation activity of Ki-67 is related to the low degree of tumor differentiation and high clinical stage.

肠癌是一种全球范围内发病率和致死率均较高的消化道恶性肿瘤,全世界每年新发病例约有120万,死于该疾病者约60万。分别居男性和女性恶性肿瘤的发病率中第三和第二位。随着我国人民饮食结构及生活方式的改变,肠癌的发病率呈明显上升趋势。中国国家癌症中心2015年的统计数据显示我国结直肠癌发病率、死亡率在全部恶性肿瘤中均位居前5位[1]。大肠癌的好发部位为直肠和乙状结肠,病理类型以腺癌为主,高发年龄>60岁[2]。大多数患者确诊时已到中晚期,生存率<30%[3]。目前,对于肠癌的临床病理特征、分子分型、治疗手段等领域的研究均取得了长足进展[4-6],但其诊疗效果仍有待于进一步提高。本研究中分子标记CK7、CK20、CEA、Ki-67在肠腺癌的诊断、鉴别诊断、预后判断及临床筛查中有重要价值。现报道如下。
