目的:评价超声引导下射频消融联合无水酒精注射治疗转移性肝癌的临床疗效。方法:对41例转移性肝癌患者的58个病灶行RFA+PEI治疗,并随访9～36个月,分析其临床疗效。结果:58个病灶治疗后1个月内行CT/MR增强检查或超声造影,89.7%(52/58)病灶完全消融,10.3%(6/58)病灶消融不全。1年存活率为88.0%。结论:超声引导下RFA+PEI联合治疗转移性肝癌是一种安全有效的方法,有较高的临床价值。
Objective: To evaluate the clinical effect of ultrasound-guided radiofrequency ablation combined with anhydrous alcohol injection in the treatment of metastatic liver cancer. Methods: Fifty-four lesions in 41 patients with metastatic liver cancer underwent RFA + PEI and were followed up for 9 to 36 months. The clinical efficacy was analyzed. Results: Fifty-eight lesions were examined by contrast-enhanced CT or MR imaging within 1 month after treatment. 89.7% (52/58) lesions were completely ablated and 10.3% (6/58) lesions were ablated. One-year survival rate was 88.0%. Conclusion: Ultrasound-guided RFA + PEI in the treatment of metastatic liver cancer is a safe and effective method with high clinical value.
