国际指南更新带来血液肿瘤治疗新思考(克拉屈滨)汇总.ppt

AML成功治疗取决于能否达到CR、能否预防复发，均受到诱导化疗疗效的影响 AML诱导治疗：年龄分界点为60岁。60岁，不良细胞遗传学特性和既往MDS更普遍，多药耐药发生率更高；并发症更多，影响患者对强烈治疗的耐受性。 60岁以下AML患者，诱导治疗的CR率极少超过70%；老年AML患者，CR率极少超过50%。CR率提高还有很大空间，需要开展大量临床研究。 NCCN指南对60岁以上、以下年龄段分别给出治疗推荐。 * 60岁以下AML患者诱导治疗，基本药物阿糖胞苷+一种蒽环类药物。DA“7+3”经典联合诱导方案，过去25年极少变化。AraC（100 mg/m2 CI）7天，DNR 45 mg/m2/d 3天。 药物剂量变迁：柔红霉素剂量：45-60 mg/m2→90 mg/m2 ×3天，或以伊达比星（IDA）替代：细胞内停留时间更长，12 mg/m2×3天，缓解率与DA方案相同。 金标准：DA 3-7方案 自1982年开始[1,2] 用另一种蒽环取代DNR或加用TG（硫鸟嘌呤）/依托泊苷，结果均无改善[3-9] 1.
