Abstract´╝Ü 目的:探讨射频消融术治疗复发性肝细胞癌对外周血肝癌细胞的影响.方法:分别采集23例复发性肝细胞癌患者射频消融治疗前、后和5位健康对照者外周血,免疫磁珠技术分离血中游离肝癌细胞,常规病理和AFP免疫组化染色验证分离到的肝癌细胞.结果: 23例复发性肝癌患者,术前外周血肝癌细胞阳性15例(65.22%),射频消融治疗1次后第1、3天,外周血肝癌细胞阳性分别为13例(56.52%)和6例(26.09%).射频消融治疗前和治疗后1 d的阳性率比较,差异无统计学意义;而治疗前和治疗后3 d、治疗后1 d和3 d的阳性率比较,差异均有统计学意义(P<0.05).结论:射频消融治疗复发性肝癌可以有效地预防或阻止肝癌血行播散.
