Although outcomes of transformed diffuse large B-cell lymphoma (DLBCL) from follicular lymphoma (FL) were improved using rituximab-combined immunochemotherapy, the efficacy of subsequent rituximab maintenance (RM) remains unclear. We retrospectively analyzed the prognoses of 519 patients with DLBCL and 62 patients with concurrent DLBCL and FL (concurrent-DLBCL/FL). Progression-free survival (PFS) was shorter in patients with concurrent-DLBCL/FL than in DLBCL (=.030). Twenty-four patients with concurrent-DLBCL/FL received RM after induction therapy, and they achieved better OS and PFS (=.010 and <.001, respectively) with lower risk of relapse (<.001) than the non-RM group. Moreover, concurrent-DLBCL/FL showed better subsequent OS and PFS after recurrence than DLBCL (=.0083 and =.0044, respectively). Our study indicates that in the face of a high relapse rate, concurrent-DLBCL/FL is manageable and benefits from RM.
虽然利妥昔单抗联合免疫化疗改善了滤泡性淋巴瘤（FL）转化的弥漫性大 B 细胞淋巴瘤（DLBCL）的预后，但随后的利妥昔单抗维持（RM）的疗效仍不清楚。我们回顾性分析了 519 例 DLBCL 患者和 62 例同时患有 DLBCL 和 FL（并发-DLBCL/FL）患者的预后。并发-DLBCL/FL 患者的无进展生存期（PFS）短于 DLBCL（=.030）。24 例并发-DLBCL/FL 患者在诱导治疗后接受 RM，与非 RM 组相比，OS 和 PFS 更好（=.010 和<.001，分别），复发风险更低（<.001）。此外，并发-DLBCL/FL 在复发后具有更好的后续 OS 和 PFS ，优于 DLBCL（=.0083 和=.0044，分别）。我们的研究表明，在面对高复发率时，并发-DLBCL/FL 是可管理的，并受益于 RM。
