Allogeneic hematopoietic stem cell transplantation (allo-HCT) is the only available curative treatment option for patients with aggressive adult T cell leukemia-lymphoma (ATL). Donor human T cell leukemia virus (HTLV) 1 seropositivity is a critical concern when choosing relative donors, as they are not usually recommended due solely to the occurrence of donor-derived ATL. A previous report suggested that allo-HCT with an HTLV-1-seropositive donor increased ATL-related mortality. We updated the risk assessment for choosing an HTLV-1-seropositive allo-HCT donor for ATL. Our current registry data, which include larger numbers of HTLV-1-seropositive donors and longer observation periods, revealed no significant difference in overall survival (hazard ratio [HR], 0.93; 95% confidence interval [CI], 0.70-1.24; P = .61) or cumulative incidence of either ATL-related (HR, 0.96; 95% CI, 0.64 to 1.45; P = .80) or non-ATL-related mortality (HR, 0.91; 95% CI, 0.61 to 1.37; P = .66). Similarly, when considering only patients with ATL in complete remission, there was no significant difference in overall survival (HR, 1.02; 95% CI, 0.70 to 1.49; P = .91) or cumulative incidence of either ATL-related (HR, 1.20; 95% CI, 0.66 to 2.20; P=0.54) or non-ATL-related mortality (HR, 0.86; 95% CI, 0.52-1.42; P = .66). These data indicate that selecting HTLV-1-seropositive donors might not be contraindicated for patients with ATL receiving allo-HCT if alternative donors are unavailable. Further risk assessment remains to be performed.

HTLV-1抗体阳性供体用于ATL的同种异体造血干细胞移植的结果。

同种异体造血干细胞移植(allo-HCT)是侵袭性成人T细胞白血病-淋巴瘤(ATL)患者的唯一可用治疗方法。选择相对的供体时,供体人类T细胞白血病病毒(HTLV)1血清反应阳性是一个至关重要的问题,因为通常不建议仅由于存在供体来源的ATL而建议不要使用它们。先前的报告表明,同种HCT与HTLV-1血清阳性的供体会增加ATL相关的死亡率。我们更新了为ATL选择HTLV-1血清异基因HCT供体的风险评估。我们当前的注册表数据包括更多的HTLV-1血清阳性供体和更长的观察期,显示总体生存率无显着差异(危险比[HR]为0.93; 95%置信区间[CI]为0.70-1.24; P =。61)或ATL相关死亡率(HR,0.96; 95%CI,0.64至1.45; P = .80)或非ATL相关死亡率(HR,0.91; 95%CI,0.61至1.37; P = .66)。同样,仅考虑完全缓解的ATL患者时,总生存率(HR,1.02; 95%CI,0.70至1.49; P = 0.91)或与ATL相关的累积发生率(HR,1.20)均无显着差异。 ; 95%CI,0.66至2.20; P = 0.54)或与非ATL相关的死亡率(HR,0.86; 95%CI,0.52-1.42; P = 0.66)。这些数据表明,如果没有其他供体,则选择HTLV-1血清阳性供体对于接受同种HCT的ATL患者可能不是禁忌的。进一步的风险评估仍有待执行。仅考虑完全缓解的ATL患者时,总生存率(HR,1.02; 95%CI,0.70至1.49; P = 0.91)或与ATL相关的累积发生率(HR,1.20; 95)均无显着差异。百分比CI,0.66至2.20; P = 0.54)或与非ATL相关的死亡率(HR,0.86; 95%CI,0.52-1.42; P = 0.66)。这些数据表明,如果没有其他供体,则选择HTLV-1血清阳性供体对于接受同种HCT的ATL患者可能不是禁忌的。进一步的风险评估仍有待执行。仅考虑完全缓解的ATL患者时,总生存率(HR,1.02; 95%CI,0.70至1.49; P = 0.91)或与ATL相关的累积发生率(HR,1.20; 95)均无显着差异。百分比CI,0.66至2.20; P = 0.54)或与非ATL相关的死亡率(HR,0.86; 95%CI,0.52-1.42; P = 0.66)。这些数据表明,如果没有其他供体,则选择HTLV-1血清阳性供体对于接受同种HCT的ATL患者可能不是禁忌的。进一步的风险评估仍有待执行。这些数据表明,如果没有其他供体,则选择HTLV-1血清阳性供体对于接受同种HCT的ATL患者可能不是禁忌的。进一步的风险评估仍有待执行。这些数据表明,如果没有其他供体,则选择HTLV-1血清阳性供体对于接受同种HCT的ATL患者可能不是禁忌的。进一步的风险评估仍有待执行。
