CT引导射频消融术治疗肝转移癌的临床价值

Clinical Value of CT-Guiding Radiofrequency Ablation in Treating Liver Metastasis Tumor

目的:评价CT引导射频消融术治疗肝转移癌的临床疗效。方法:对38例肝转移癌患者采用CT引导经皮穿刺射频消融术治疗,对比瘤体体积变化,总结客观应答率,随访统计生存率。结果:治疗后2个月复查CT评价疗效,完全缓解(CR)15例,部分缓解(PR)11例,稳定(NC)8例,进展(PD)4例,有效率(CR+PR)为68.42%。肿瘤病灶小于5cm的患者疗效较好。无治疗相关并发症。随访3个月、6个月、1年、2年,生存率分别为97.37%、86.84%、71.05%、57.89%。结论:CT引导射频消融术治疗肝转移癌近期疗效确切值得临床应用。

Objective： To evaluate the clinical value of CT-guiding radiofrequency ablation（RF） in the treatment of liver metastasis tumor. Methods： Clinical records of 38 patients with liver metastasis cancer who received RF treatment were analyzed. The response rate, tumor volume and survival rate were compared. Results： Computer tomography was used to evaluate response rates two months after radiofrequency ablation. Complete response was achieved in 15 of 38 evaluable patients, partial response in 11, stable dis- ease in 8 and progressive disease in 4. The total response rate was 68.42% and a better response rate was achieved in patients with tumor size under 5cm. No treatment related severe complication was observed. The survival rate was 97.37%, 86.84%, 71.05% and 57.89% in the follow-up time of 3 months, 6 months, 1 year and 2 years respectively. Conclusion： CT-guiding radiofrequency ablation is a safe and effective approach in treating liver metastasis tumors.
