Abstract
目的 探讨结直肠癌肝转移患者血清中 CD44和 CD54含量与结直肠癌肝转移发生发展的关系,寻找一个稳定的早期诊断结直肠癌肝转移的生物学指标.方法应用酶联免疫吸附测定方法( ELISA)检测 38例结直肠癌和 21例结直肠癌肝转移患者以及 40例健康成人(正常对照组)的血清 CD44和 CD54含量, 并比较血清中 CD44和 CD54含量在治疗前后的变化.结果结直肠癌肝转移组和结直肠癌组血清中 CD44和 CD54含量明显高于正常对照组,且结直肠癌肝转移组较结直肠癌组含量也明显增高.结直肠癌肝转移组和结直肠癌组治疗后的血清 CD44和 CD54含量比治疗前下降.结论 CD44和 CD54可以作为临床早期诊断结直肠癌肝转移的生物学指标,同时也可以作为监测结直肠癌和结直肠癌肝转移预后的客观指标.
