摘　　要：目的探讨聚乙烯醇颗粒(PVA)在原发性肝癌经导管肝动脉化疗栓塞术(TACE)中的应用价值。方法对20例肝癌患者行TACE术,术中先使用碘化油化疗药物混合乳剂栓塞肿瘤血管,再用PVA颗粒超选择性插管栓塞肿瘤供血动脉。观察患者术后1个月、3个月、6个月、1年时肿瘤缩小程度、治疗有效率及甲胎蛋白(AFP)水平变化;术后1周及1个月时血清天门冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)及总胆红素(TBILI)水平,记录疾病进展时间及生存期。结果术后1个月、3个月、6个月、1年肿瘤直径均较术前明显缩小(P<0.05),其治疗有效率(完全缓解+部分缓解)分别为80.00%、90.00%、95.00%、95.00%,AFP水平较术前明显下降(P<0.05)。术后1周AST、ALT、TBILI均较术前明显升高(P<0.05),但1个月时AST、ALT、TBILI均恢复为术前水平。随访时间12～32(19.8±7.0)个月,疾病进展时间为(17.0±6.8)个月,总生存时间为(19.3±7.0)个月。结论PVA颗粒作为永久性栓塞材料,在肝癌TACE中栓塞效果明显,但术中需超选择性插管到肿瘤供血动脉内进行栓塞治疗。Objective To assess the clinical value of transcatheter arterial chemoembolization（TACE） with polyvinyl alcohol（PVA） particles as embolic material in patients with primary hepatic cancer（PHC）.Methods Twenty patients with PHC underwent TACE.The mixed emulsion of chemotherapy agents and lipiodol was given to embolize the tumor vessels,and then PVA particles were injected superselectively into the feeding artery of tumors.The tumors size,response rate and Alpha-Fetoprotein（AFP） value were monitored respectively at the end of the first month,the third month,the sixth month and the first year after TACE.The changes of liver function,including serum aspartate aminotransferase（AST）,alanine aminotransferase（ALT） and total bilirubin（TBILI）,were recorded within 1 week and 1 month after TACE.The time to progression and the overall survival were recorded.Results Compared with pre-TACE,the tumor size decreased obviously at the end of the first month,the third month,the sixth month and the first year after TACE（P 0.05）,the response rate reached 80.00%,90.00%,95.00% and 95.00%,respectively.The AFP value decreased obviously.Serum AST,ALT and TBILI significantly increased in the first week after TACE（P 0.05）,but returned to preoperative level within 1 month.The average follow-up time was（19.8±7.0） months（range 12—32 months）,the time to progression was（17.0±6.8） months,and the overall survival was（19.3±7.0） months.Conclusion PVA particles are optimal embolic material for TACE of PHC.Superselective embolization is necessary in TACE to achieve effective tumor devascularization and reduce liver damage.
