超声引导下经皮射频消融治疗中晚期肝癌的临床研究

目的评价B超引导下冷循环射频肿瘤治疗仪射频消融(RFA)治疗中晚期肝癌的临床疗效及并发症。方法采用超声引导下经皮穿刺冷循环RFA治疗中晚期肝癌25例,其中转移性肝癌8例,原发性肝癌17例。每个病灶进行RFA1～2次。其中8例患者术前给予3次TACE治疗。术后通过增强CT扫描评价疗效。结果10个病灶完全坏死,余15个病灶大部分坏死。随访半年,25例患者现全部存活且生存质量明显提高。结论超声引导下经皮穿刺冷循环RFA治疗中晚期肝癌短期效果满意,值得推广。

Clinical research on advanced liver cancer treated with percutaneous RFA cool-tip electrode under ultrasound guidance

Objective To evaluate the clinical efficacy and complications in the treatment of advance liver cancer under ultrasound guidance with percutaneous RFTI-1 TM-cold cycle RF tumor ablation apparatus produced by Nangjing TianMa high-tech Company limited. Methods 25 patients of advance liver cancer, including 8 cases of metastatic liver cancer, 17 of primary hepatic carcinoma, were treated with percutaneous RFA cool-tip electrode under Ultrasound guidance 1 to 2 times. Eight of the patients prior to RFA were treated with TACE of individually three times for each. The postoperative efficacy was evaluated by enhanced CT. Results 10 lesions were completely necrotized and the majority parts of another 15 lesions were also under necrosis. Follow-up of six months, all patients are still alive with marked improvement of life quality. Conclusion The short-term efficacy of percutaneous Ultrasound-guided RFA with cool-tip electrode for treating advance liver cancer is quite satisfied, worthy to be recommended.
