高强度聚焦超声治疗中晚期原发性肝癌对患者免疫状态的影响

目的 观察高强度聚焦超声（HIFU）治疗中晚期原发性肝癌对患者免疫状态的影响。方法 对2003年3月至2003年12月我院收治的40例原发性肝癌患者行HIFU治疗，对其治疗前后进行自身比较并与射频治疗组进行比较，观察分析原发性肝癌患者在接受HIFU治疗后的免疫指标（cD3、cD4、CD8、CD4／CD8、NK、IL-2、TNF）变化。结果 HIFU治疗组与射频治疗组3、6、9个月及1年生存率比较，差异无统计学意义；患者上述各项免疫指标于HIFU治疗前后相比较差异无统计学意义，与射频治疗组比较，差异亦无统计学意义。结论 HIFU治疗中晚期原发性肝癌对患者早期免疫状态的影响不明显。

Effect of High Intensity Focused Ultrasound on Immunity of Patients with Advanced Primary Liver Cancer

Objective To investigate the effect of high intensity focused ultrasound(HIFU) on the immunity of patients with advanced primary liver cancer(PLC).Methods Forty cases of PLC admitted to our institution from Mar.2003 to Dec.2003 were included in this study.Patients were divided into 2 groups and received either HIFU or radio-frequency ablation(RFA) treatment randomly.CD3,CD4,CD8,CD4/CD8,NK,IL-2,TNF were chosen to assess the immune status before and after treatment.The results were compared statistically.(Results The) survival rate after HIFU was 80.0%,61.1%,42.9%,33.3% at 3 months,6 months,9 months and 1 year respectively,which was similar to that after RFA treatment.The changes of immunity parameters of CD3,CD4,CD8,CD4/CD8,NK,IL-2 and TNF were not significant after HIFU treatment.In addition,the differences of those parameters between HIFU group and RFA group were insignificant.Conclusion There are no detrimental effects on immunity in the early period after HIFU treatment.
