急性淋巴细胞白血病 (ALL)一线治疗方案
权威癌症研究机构美国国家癌症研究所 (NCI)对急性淋巴细胞白血病 (缓解期成人急性淋巴细胞白血病 (ALL))一线治疗方案:缓解后治疗(化疗+BCR-ABL酪氨酸激酶抑制剂(伊马替尼))。
缓解后治疗(化疗+BCR-ABL酪氨酸激酶抑制剂(伊马替尼))治疗急性淋巴细胞白血病 (缓解期成人急性淋巴细胞白血病 (ALL))医学证据
一、几项试验,包括癌症和白血病 B 组 (CLB-8811) 和完整的欧洲肿瘤协作组 ( ECOG-2993 [NCT00002514])[1]对成人 ALL 的积极缓解后化疗的研究证实了长期无病生存(DFS) 率约为 40%。[2-3]
1.在两个系列中,[ 4 , 5 ] 发现 T 细胞系ALL患者预后特别好,接受缓解后治疗的患者的 DFS 率为 50% 至 70%。
2.这些系列代表了 DFS 率与以前不太密集的化疗方法相比有了显着改善。
二、相比之下,费城染色体 (Ph1) 阳性ALL、具有 L3 表型(表面免疫球蛋白阳性)的 B 细胞谱系 ALL 和以 t(4;11) 为特征的 B 细胞谱系 ALL 患者的治愈率较低。
较新的剂量密集方案的管理可能很困难,应由具备这些方案经验的医生在有能力处理潜在并发症的中心执行。取消继续或维持化疗的研究结果不如延长治疗时间的研究。[6,7] 伊马替尼已被纳入Ph1阳性ALL患者的维持治疗方案中。 [8,9]
