目的探讨射频消融(RFA)在消化道恶性肿瘤肝转移瘤中的应用价值。方法回顾性研究消化道恶性肿瘤肝转移患者78例,共147个病灶的临床及随访资料。结果 RFA消融效果在<3cm的病灶中要明显优于>3cm的病灶(P<0.05)。术后1、2、3、4年和5年的总体生存率为89.6%、66.7%、33.3%、12.5%和4%。RFA对于结肠癌肝转移瘤术后的复发率及生存率有效(P<0.05)。结论 RFA治疗结肠癌肝转移可以取得较好效果,值得在临床推广与应用。
Objective To investigate the value of radiofrequency ablation (RFA) in hepatic metastases of gastrointestinal malignancies. Methods A retrospective study of 78 patients with hepatic metastases of gastrointestinal malignant tumors, a total of 147 lesions clinical and follow-up data. Results The ablation effect of RFA was significantly better than that of> 3 cm in lesions <3 cm (P <0.05). The overall survival at 1, 2, 3, 4 and 5 years after surgery was 89.6%, 66.7%, 33.3%, 12.5% and 4%, respectively. RFA was effective for postoperative recurrence and survival rate of colon cancer with liver metastases (P <0.05). Conclusion RFA treatment of liver metastasis of colon cancer can achieve better results, it is worth in the clinical promotion and application.
