摘要 目的探讨CEA检测对Ⅰ和Ⅱ期结直肠癌淋巴结微转移的临床意义。方法以癌胚抗原(carcinoembryonic antigen,CEA)为载体对结直肠癌淋巴结进行染色的方法,检测Ⅰ和Ⅱ期结直肠癌患者淋巴结共126例,均为胃肠组医师行结直肠癌根治术,术后平均随访64.11(64 ̄106)个月,统计临床病理因素及微转移对术后5年无瘤生存率的影响。结果每例结直肠癌的淋巴结数平均在10枚以上。在病理因素中,"淋巴管侵犯"和"肿瘤侵袭深度"与淋巴结的CEA表达呈正相关,而其他临床病理因素对淋巴结CEA表达无明显相关性。10个临床病理因素对5年无瘤生存率均无统计学意义。淋巴结CEA表达阴性、微转移的患者中,5年无瘤生存率分别为75.8%和56.1%。MCM与CEA(-)比较,5年无瘤生存率明显降低(P<0.05)。结论对于Ⅰ和Ⅱ期结直肠癌,若淋巴结中检测出微转移,其预后较差,术后复发率较高,应予以积极的术后辅助化疗。
