Progression or relapse in the central nervous system (CNS) remains a rare but mostly fatal event for patients with diffuse large B-cell lymphoma (DLBCL). In a retrospective analysis of 5189 patients treated within 19 prospective German and French phase 2/3 trials, we identified 159 patients experiencing a CNS event (relapse: 62%, progression: 38%). Intracerebral, meningeal, intraspinal, or combined involvement was reported in 44%, 31%, 3%, and 22% of patients, respectively. 62 of 155 evaluable patients (40%) showed concurrent systemic progression/ relapse. 82% of all CNS events occurred within two years after study inclusion or randomization. 87% of patients showed extranodal involvement outside the CNS. Patients generally had poor outcomes with a median overall survival (OS) of 3.4 months (95% CI 2.9–4.2) and a 2-year OS of 15% (10–22%). Outcomes did not differ depending on the site or time point of CNS events. Patients with isolated CNS events demonstrated significantly better OS (p = 0.023). Twenty-five patients were consolidated with autologous or allogeneic stem cell transplantation and achieved a 3-year OS of 36% (20–66%). This large study including more than 5000 DLBCL patients highlights the unmet medical need to improve the outcome of DLBCL patients suffering from CNS relapse.

在 19 项前瞻性 2 期和 3 期试验中,DLBCL 患者 CNS 复发的识别、危险因素和临床病程——LYSA 和 GLA/DSHNHL 合作
对于弥漫性大 B 细胞淋巴瘤 (DLBCL) 患者来说,中枢神经系统 (CNS) 的进展或复发仍然是一种罕见但大多致命的事件。在对 19 项前瞻性德国和法国 2/3 期试验中接受治疗的 5189 名患者进行回顾性分析时,我们确定了 159 名发生 CNS 事件的患者 (复发率:62%,进展率:38%)。据报道,44% 、 31% 、 31% 、 3% 和 22% 的患者分别有脊髓内、脑膜内、脊髓内或联合受累。155 名可评估患者中有 62 名 (40%) 显示并发全身进展/复发。82% 的 CNS 事件发生在研究纳入或随机化后的两年内。87% 的患者显示 CNS 外结外受累。患者的结局通常较差,中位总生存期 (OS) 为 3.4 个月 (95% CI 2.9-4.2),2 年 OS 为 15% (10-22%)。结局不因 CNS 事件的部位或时间点而异。孤立的 CNS 事件患者表现出显着更好的 OS (p = 0.023)。25 例患者接受自体或同种异体干细胞移植巩固,3 年 OS 为 36% (20-66%)。这项包括 5000 多名 DLBCL 患者的大型研究强调了改善 DLBCL 患者复发预后未得到满足的医疗需求。
