摘要
目的:探讨血清CEA、CA19-9和CA242在结直肠癌临床病理中的特点。方法:收集2006年1-9月,上海交通大学医学院附属新华医院普外科手术治疗结直肠癌患者192例(C组),正常对照者50例(A组)和结直肠良性病患者50例(B组),术前测定血清CEA、CA19-9和CA242含量,结直肠癌标本做免疫组化检测p53和Ki67蛋白表达,统计分析结果。结果:C组血清CEA[(22.03±16.42)ng/mL]和CA242[(29.22±22.40)U/mL]均明显升高(均P<0.01),且在D期呈显著上升。血清CEA[(38.18±27.43)ng/mL]和CA19-9[(86.85±69.32)U/mL]在近端结肠癌中表达水平较远端结肠癌和直肠癌升高(均P<0.05)。CEA在低分化癌[(31.69±28.72)ng/mL]和黏液腺癌[(35.42±20.01)ng/mL]中明显升高(均P<0.01)。p53蛋白表达(+++)者的CEA[(34.21±14.33)ng/mL]和CA242[(37.42±29.05)U/mL]显著高于其他组(均P<0.01)。Ki67表达(+++)者的CEA[(37.79±26.79)ng/mL]和CA242[(32.94±23.78)U/mL]亦均明显高于其他组(均P<0.01)。结论:CEA、CA242和CA19-9水平升高预示结直肠癌肿瘤分期较晚、肿瘤细胞增殖较强,尤其CEA更提示肿瘤低分化和较差病理类型。
