肝癌RFA后复发的常规超声表现

Conventional Ultrasound Performance of Recurrence after Liver Cancer Radiofrequency Ablation

目的:总结肝癌射频消融(RFA)后复发病灶的常规超声表现。方法:回顾性分析29例肝癌RFA经治疗完全后复发的常规超声及增强影像学资料、AFP(复发组),并从同期212例肝癌RFA治疗完全无复发的患者中选取条件相似的29例作比较(无复发组)。结果:复发组与无复发组在常规超声表现消融区不规则的低回声、肝内新发低回声及AFP升高方面的差异有统计学意义(P均<0.05)。结论:肝癌RFA后复发的常规超声表现有消融区不规则的低回声、肝内新发低回声、脉管癌栓、肝外转移及AFP升高时,诊断复发阳性率高,需要进行增强影像学检查。

Objective:To conclude conventional ultrasound performance of recurrence after liver cancer radiofrequency ablation.Methods:Select 29 cases of conventional ultrasound,enhanced imaging files and AFP of patients whose disease relapsed after receiving RFA treatment as recurrence group.Select 29 cases of patients whose disease didn't relapse after receiving RFA treatment from 212 cases during the same period as non-recurrence group.Results:The differences in irregular low echo of conventional ultrasound performance ablation area,new low echo in liver and increase in AFP between the two groups were statistically significant(P<0.05).Conclusions:When conventional ultrasound performance of recurrence after receiving RAF treatment has irregular low echo of conventional ultrasound performance ablation area,new low echo in liver and increase in AFP,recurrence rate is diagnosed to be high and enhanced imaging examination is necessary.
