大肠癌肝转移的射频消融治疗

Percutaneous radiofrequency ablation in the treatment of liver metastasis caused by colorectal cancer

目的研究大肠癌肝转移射频消融（RFA）治疗近期局部疗效和不良反应。方法大肠癌肝转移患者32例，病灶总数71个，其中直径小于4．0cm的病灶41个，4．1-5．0cm者14个，5．1-6．0cm者9个，大于6．1cm者7个。经RFA治疗1个月后行螺旋CT双期增强扫描评价肿瘤治疗效果。结果不同大小瘤灶经消融治疗后达到完全坏死者分别为41个（41／41），13个（13／14），4个（4／9），2个（E17）。无严重不良反应和并发症。结论RFA安全可靠，不良反应小，是治疗大肠癌肝转移的有效方法之一。

Objective To analyze the local therapeutic efficacy, side effect and complication of 32 patients with liver metastasis caused by colorectal cancer treated by percutaneous radiofrequency ablation （RFA）. Methods RFA was performed on 71 tumors in 32 patients under the guidance of CT scanning.The results were evaluated by the double-phase CT scanning. Results The complete coagulative necrosis rates were 100 % ,92.8 % ,44 % ,28 % in tumor with diameters of less than 4.0 cm,4.1 -5.0 cm,5.1 - 6.0 cm and large than 6.1 cm respectively. Conclusions RFA is safe,effective and reliable in the treatment of liver metastasis caused by colorectal cancer.
