目的:研究射频消融(RFA)与手术切除(SR)治疗原发性小肝癌的临床效果差异。方法:将高州市中医院2010年7月至2012年6月收治的78例原发性小肝癌患者抽签随机分为观察组与对照组,观察组采取射频消融治疗,对照组采取手术切除治疗,比较两组患者治疗后肿瘤近远期复发率及生存率。结果:射频组治疗3月、1年、2年复发率分别为17.50%、30.00%、37.50%,与手术组10.53%、31.58%、52.63%比较,差异均无统计学意义(P>0.05);射频组3月、1年、2年的无瘤生存率分别为92.50%、70.00%、47.50%,生存率为95.00%、87.50%、77.50%,与手术组无瘤生存率92.11%、78.95%、55.26%及生存率94.74%、89.47%、86.84%比较,差异均无统计学意义(P>0.05)。结论:RFA及SR均为原发性小肝癌治疗的有效方式,两组复发率、生存率无明显差异,提示RFA可考虑作为SR替代疗法进行推广。
Objective: To study the clinical effects of radiofrequency ablation (RFA) and surgical resection (SR) in the treatment of primary small hepatocellular carcinoma. Methods: 78 patients with primary small hepatocellular carcinoma admitted from July 2010 to June 2012 in Gaozhou City Hospital were randomly divided into observation group and control group. The observation group was treated by radiofrequency catheter ablation and the control group was treated by surgical resection. The tumor recurrence rate and survival rate of the two groups were compared after treatment. Results: The recurrence rates of radiofrequency group at 3 months, 1 year and 2 years were 17.50%, 30.00% and 37.50% respectively. There was no significant difference between the two groups (P> 0.05) . The tumor-free survival rates of the radiofrequency group in March, 1 year and 2 years were 92.50%, 70.00% and 47.50% respectively, and the survival rates were 95.00%, 87.50% and 77.50% respectively. The tumor-free survival rates were 92.11% and 78.95 %, 55.26% and survival rate 94.74%, 89.47%, 86.84% respectively. There was no significant difference between the two groups (P> 0.05). Conclusion: Both RFA and SR are effective methods for the treatment of primary small hepatocellular carcinoma. There is no significant difference between the two groups in relapse rate and survival rate, suggesting that RFA may be considered as an alternative therapy for SR.
