早期应用供体淋巴细胞输注治疗慢性髓性白血



对于经异体干细胞移植后出现复发的慢性髓性白血病(CML)患者,其治疗主要为酪氨酸激酶抑制剂和(或)供体淋巴细胞输注。研究纳入例异体干细胞移植后分子学复发的患者,且这些患者随后均接受了淋巴细胞输注。例患者于首次慢性期接受了移植治疗,29例患者于进展期接受移植治疗。84例患者供体为亲属,71例供体为非亲属(-年间)。自复发至淋巴细胞输注的中位间隔时间为(0-)天。中位随访时间为46(3-)个月。结果显示,淋巴细胞输注后的5年总生存率为76±4%(亲属供体:89±8%;非亲属供体:63±13%,[P=0.])。分子学复发后6个月以内及以后接受淋巴细胞输注的患者,其生存率分别为69±14%和81±10%(P=0.)。多变量分析显示,非亲属供体患者生存较差(HR2.54[95%CI:1.15-5.53],P=0.),复发6个月以后接受淋巴细胞输注的患者生存更佳(HR0.4[95%CI:0.19-0.84],P=0.)。研究表明,对于经异体干细胞移植后复发的CML患者,淋巴细胞输注具有显著疗效,但与分子学复发后较晚输注淋巴细胞相比,较早输注淋巴细胞并无优势。

该研究正式发表于年9月《血液病学》杂志上(Haematologica.Sep;99(9):-8)。
