【摘要】 目的探讨CT导向下水循环冷却式微波刀消融治疗技术在结直肠癌肝转移瘤治疗中的意义。方法2007年6月～2008年9月共16例结直肠癌肝转移患者,27个转移灶,其中直径小于3.0cm的病灶共9个,3.0cm～4.0cm者12个,4.0cm～5.0cm者4个,大于5.0cm者2个,平均3.5cm±0.8cm,均采用CT导向下水循环冷却式微波刀消融治疗,术后第1、3个月分别行螺旋CT双期增强扫描评价治疗疗效。结果肿瘤影像学评价,16例患者27例病灶中,完全缓解(complete remission,CR)23个,部分缓解(partial remission,PR)3个,稳定(nochange,NC)1个。全组16例目前全部存活,随访时间最长15个月,最短6个月,近期平均生存期10个月。结论CT导向下水循环冷却式微波刀消融治疗技术是治疗直肠癌肝转移瘤的安全、微创、有效的方法。更多还原

【Abstract】 Objective To analyze the clinical value of CT guided Water circulatory-cooling percutaneous microwave ablation in the treatment of liver metastases caused by colorectal cancers. Methods The retrospective analysis was undertaken in 16 patients with 27 metastases from Jun.2007 to Sep.2008. Nine metastatic nodules had less than 3.0cm in diameter and twelve nodules’diameter was between 3.0cm-4.0cm,four was between 4.0cm-5.0cm, two was longer than 5.0cm,and the average diameter was 3.5 cm±0.8 cm. All the patients with liver metastases caused by colorectal cancers were treated by CT guided Water circulatory-cooling percutaneous microwave ablation. All the patients underwent followed CT scan after 1 and 3 months later. Results: According to the results of the CT scan, there were 23 complete remission (CR) ,3 partial remission ( PR),1 stable disease (SD) in all of the metastatic nodules. All the 16 patients are still alive now, the longest followed span is 15 months, and the shortest is 6 months, the average followed span is 10 months. Conclusion: CT guided Water circulatory-cooling percutaneous microwave ablation is a safe and effective method in the treatment of liver metastases caused by colorectal cancers with few complication.更多还原
