Abstract:
Autologous(auto-) and allogeneic(allo-) hematopoietic stem cell transplantation (HSCT) are key treatments for relapsed/refractory diffuse large B-cell lymphoma (DLBCL), although their roles are challenged by CAR-T-cells and other immunotherapies. We examined the transplantation trends and outcomes for DLBCL patients undergoing auto-/allo-HSCT between 1990 and 2021 reported to EBMT. Over this period, 41,148 patients underwent auto-HSCT, peaking at 1911 cases in 2016, while allo-HSCT saw a maximum of 294 cases in 2018. The recent decline in transplants corresponds to increased CAR-T treatments (1117 cases in 2021). Median age for auto-HSCT rose from 42 (1990-1994) to 58 years (2015-2021), with peripheral blood becoming the primary stem cell source post-1994. Allo-HSCT median age increased from 36 (1990-1994) to 54 (2015-2021) years, with mobilized blood as the primary source post-1998 and reduced intensity conditioning post-2000. Unrelated and mismatched allo-HSCT accounted for 50% and 19% of allo-HSCT in 2015-2021. Three-year overall survival (OS) after auto-HSCT improved from 56% (1990-1994) to 70% (2015-2021), p < 0.001, with a decrease in relapse incidence (RI) from 49% to 38%, while non-relapse mortality (NRM) remained unchanged (4%). After allo-HSCT, 3-year-OS increased from 33% (1990-1999) to 46% (2015-2021) (p < 0.001); 3-year RI remained at 39% and 1-year-NRM decreased to 19% (p < 0.001). Our data reflect advancements over 32 years and >40,000 transplants, providing insights for evaluating emerging DLBCL therapies.
摘要:
自体(自体)和异基因(同种)造血干细胞移植(HSCT)是复发/难治性弥漫性大B细胞淋巴瘤(DLBCL)的关键治疗方法,尽管它们的作用受到CAR-T细胞和其他免疫疗法的挑战。我们研究了1990年至2021年间接受自体/同种异体HSCT的DLBCL患者的移植趋势和结果,并报告给EBMT。在此期间,41,148名患者接受了自动HSCT,2016年达到1911例病例的峰值,而allo-HSCT在2018年最多达到294例。最近移植的减少与CAR-T治疗的增加相对应(2021年为1117例)。Auto-HSCT的中位年龄从42岁(1990-1994年)上升到58岁(2015-2021年),1994年后外周血成为主要的干细胞来源。Allo-HSCT的平均年龄从36岁(1990-1994年)增加到54岁(2015-2021年),以动员的血液为1998年后的主要来源,并在2000年后降低了调节强度。在2015-2021年,不相关和不匹配的allo-HSCT分别占allo-HSCT的50%和19%。自动HSCT后的三年总生存率(OS)从56%(1990-1994)提高到70%(2015-2021)。p<0.001,复发率(RI)从49%降低到38%,而非复发死亡率(NRM)保持不变(4%)。在allo-HSCT之后,3年OS从33%(1990-1999)增加到46%(2015-2021)(p<0.001);3年RI保持在39%,1年NRM下降到19%(p<0.001)。我们的数据反映了32年来的进步和超过40,000例移植,为评估新兴的DLBCL疗法提供见解。
