初治和复发/难治性慢性淋巴细胞白血病使用伊布替尼单药治疗的5年经验 研究人员先前已经报道了未接受过治疗(TN)的老年患者(≥65岁)和慢性淋巴细胞白血病/小淋巴细胞性淋巴瘤的复发/难治性(R/R)患者的3年随访中伊布替尼的持久应答和可管理的安全性(CLL / SLL)数据。在此,研究人员进一步报道了长期有效性和安全性,对TN患者(N=31)和R/R(N=101)患者进行5年随访。随着5年随访的进

研究人员先前已经报道了未接受过治疗(TN)的老年患者(≥65岁)和慢性淋巴细胞白血病/小淋巴细胞性淋巴瘤的复发/难治性(R/R)患者的3年随访中伊布替尼的持久应答和可管理的安全性(CLL / SLL)数据。在此,研究人员进一步报道了长期有效性和安全性,对TN患者(N=31)和R/RN=101)患者进行5年随访。随着5年随访的进行,伊布替尼继续产生高达89%的总体有效率,随着时间的推移,完全缓解率增加至29%,而R/R患者则为10%。TN患者的5PFS率为92%,R/R患者为44%。R/R患者的中位PFS51个月,del11q),del17p)和未突变的IGHV患者的中位PFS分别为512643个月,表明伊布替尼在某些高风险患者亚组中的长期疗效。对于del17p)的R/R患者以及接受过更多治疗的患者,生存结局较差。≥3级的血细胞减少不良反应,如中性粒细胞减少症和血小板减少症的发作随着时间的推移而降低。与随后的时间段相比,治疗限制性不良事件在第一年更为频繁。这些结果证明了伊布替尼的长期治疗具有持续疗效和可接受的耐受性。
