摘要

目的大剂量甲氨蝶呤(HD-MTX)广泛应用于中枢神经系统(CNS)复发风险高的弥漫大b细胞淋巴瘤(DLBCL)患者。确保以最小的不良事件安全预防给药是一个关键问题;然而,很少有研究详细说明HD-MTX预防高危DLBCL患者的安全性。我们分析了该人群中与HD-MTX相关的不良事件,重点是延迟MTX消除。方法:本多中心回顾性研究纳入了2014年至2020年期间接受HD-MTX一线治疗的98例中枢神经系统复发高风险DLBCL患者。中枢神经系统预防包括2个周期的HD-MTX (3.0 g/m2),间隔2周。结果诊断时的中位年龄为63(34-84)岁,34例患者接受减剂量甲氨蝶呤(MTX)治疗。MTX延迟消除的总发生率为18.4%。在接受3小时MTX输注组(n=50)中未观察到MTX延迟消除的病例。MTX延迟消除患者的毒性反应发生率高于未消除患者(77.8% vs. 26.2%, p≤0.05),包括≥3级不良事件和≤2级肾功能障碍的发生率较高。结论甲氨蝶呤延迟消除与并发症增加有关。较短的甲氨蝶呤输注速率,特别是在3小时,可以降低甲氨蝶呤延迟消除的风险。

Delayed Methotrexate Elimination Following High-dose Methotrexate Prophylaxis in High-risk Diffuse Large B-cell Lymphoma.

Objective High-dose methotrexate (HD-MTX) is widely used as central nervous system (CNS) prophylaxis in patients with diffuse large B-cell lymphoma (DLBCL) who are at a high risk of CNS relapse. Ensuring safe prophylactic administration with minimal adverse events is a key concern; however, few studies have detailed the safety profile of HD-MTX prophylaxis in patients with high-risk DLBCL. We analyzed the adverse events associated with HD-MTX in this population, focusing on delayed MTX elimination. Methods This multicenter retrospective study included 98 patients with DLBCL at high risk of CNS relapse who received HD-MTX as part of frontline therapy between 2014 and 2020. CNS prophylaxis involved 2 cycles of HD-MTX (3.0 g/m2) at 2-week intervals. Results The median age at the diagnosis was 63 (34-84) years old, and 34 patients received a reduced methotrexate (MTX) dose. The overall incidence of delayed MTX elimination was 18.4%. No cases of delayed MTX elimination were observed in the group that received a 3-h MTX infusion (n=50). Toxicities were more frequent in patients with delayed MTX elimination than in those without (77.8% vs. 26.2%, p≤0.05), including higher incidences of grade ≥3 adverse events and grade ≤2 renal dysfunction. Conclusion Delayed MTX elimination is associated with increased complications. Shorter MTX infusion rates, particularly at 3 h, may reduce the risk of delayed MTX elimination.
