目的 比较经皮瘤内注射无水酒精和醋酸对肝癌的治疗效果。方法 肝癌患者 12例 ,病灶 46个 ,1 0～ 3 5cm大小。分别于超声引导下经皮瘤内注射无水酒精 ( 2 1个 )和 75 %醋酸 ( 2 5个 )。 2个月后复查 ,观察肿瘤的变化情况。结果 治疗前两组肿块大小无差别 (P >0 0 5 ) ,治疗后复查 ,PEI组肿块明显大于PAI组 (P <0 0 5 ) ,局部复发率PEI组 ( 10 /2 1)明显高于PAI组 ( 3 /2 5 )(P <0 0 1)。结论 PAI术对肝癌的治疗效果优于PEI术
Objective To compare the therapeutic effect of percutaneous intratumoral injection of anhydrous alcohol and acetic acid on liver cancer. Methods There were 12 patients with liver cancer, 46 lesions and 10 ~ 35cm in size. Intratumoral injection of anhydrous alcohol (21) and 75% acetic acid (25) were performed under ultrasound guidance. 2 months after the review, observation of tumor changes. Results There was no significant difference in tumor size between the two groups before treatment (P> 0.05). After treatment, the mass in PEI group was significantly larger than that in PAI group (P <0.05). The local recurrence rate in PEI group was significantly higher than that in PEI group PAI group (3/25) (P <0.01). Conclusion PAI is superior to PEI in the treatment of liver cancer
