单用表阿霉素缓释剂及联合表阿霉素游离剂腹腔化疗治疗肝癌的疗效

Abstract

目的观察单用表阿霉素(EPI)聚乳酸(PLA)缓释微球(MS)及联合游离表阿霉素(FEPI)腹腔化疗治疗肝癌的疗效。方法将35只H22腹水型肝癌荷瘤小鼠分为7组,每组5只,分别予空白微球,生理盐水,低、中、高剂量载药微球(分别含EPI 9、18、36 mg/kg),FEPI(9 mg/kg)和EPI-PLA-MS+FEPI(各含EPI 4.5 mg/kg),经腹腔注射给药,计算动物生命延长率。结果EPI-PLA-MS能有效延长荷瘤鼠的生存时间,并呈量效关系,小鼠最大耐受量约为18~36 mg/kg。联合用药组的平均生存时间、中位生存时间和生命延长率均达到最高值,分别为(40.0±16.9)d、33.5 d和222.58%。结论EPI-PLA-MS缓释剂与游离剂型联合腹腔化疗是一种新型、高效的给药方式,可有效治疗肝癌
