Abstract

Background

Double-expressor diffuse large B-cell lymphoma (DE-DLBCL) has a poor prognosis, and optimal treatment strategies remain unclear. This study evaluates the efficacy and safety of RCHOP, R2-CHOP (RCHOP plus lenalidomide), and RCHOP plus Bruton's Tyrosine Kinase inhibitors (BTKi) in DE-DLBCL treatment.

Methods

Data from 213 DE-DLBCL patients treated from January 2019 and February 2024. Among them, 112 received R-CHOP, 65 received R2-CHOP, and 36 received R-CHOP plus BTKi. We evaluated clinical characteristics, overall response rate (ORR), complete response (CR) rate, progression-free survival (PFS), overall survival (OS), and adverse events (AEs) for each groups.

Results

Baseline characteristics were comparable across groups. ORRs were 95.5 % for R-CHOP, 96.9 % for R2-CHOP, and 97.2 % for R-CHOP plus BTKi, with CR rates of 76.5 %, 80 %, and 75 %, respectively. BTKi significantly improved PFS (p=0.033) but not affect OS (p=0.165). Lenalidomide showed no benefit in PFS (p=0.153) or OS (p=0.351). With median follow-up times of 20.6 months for R-CHOP, 23.5 months for R2-CHOP, and 17.6 months for R-CHOP plus BTKi, the 1-year PFS rates were 73.6 %, 82.2 %, and 93.3 %, and the 1-year OS rates were 96.2 %, 93.2 %, and 100 %, respectively. Grade 3–4 adverse events included leukopenia, neutropenia, and anemia, and thrombocytopenia, with no significant differences among groups.

Conclusion

The addition of BTK inhibitor enhances progression-free survival in DE-DLBCL, especially in advanced-stage patients, without introducing new severe adverse reactions. In contract, adding lenalidomide does not offer additional efficacy or survival benefits.

与RCHOP加来那度胺不同，RCHOP加BTK抑制剂可改善双表达弥漫大B细胞淋巴瘤的临床疗效。

背景：双表达弥漫大B细胞淋巴瘤（DE-DLBCL）预后较差，最佳治疗策略仍不明确。本研究评估了RCHOP、R2-CHOP（RCHOP加来那度胺）和RCHOP加布鲁顿酪氨酸激酶抑制剂（BTKi）治疗DE-DLBCL的疗效和安全性：数据来自2019年1月至2024年2月接受治疗的213例DE-DLBCL患者。其中，112 人接受了 R-CHOP，65 人接受了 R2-CHOP，36 人接受了 R-CHOP 加 BTKi。我们评估了各组的临床特征、总反应率（ORR）、完全反应率（CR）、无进展生存期（PFS）、总生存期（OS）和不良事件（AEs）：各组的基线特征相当。R-CHOP的ORR为95.5%，R2-CHOP为96.9%，R-CHOP加BTKi为97.2%，CR率分别为76.5%、80%和75%。BTKi能明显改善PFS（p=0.033），但不影响OS（p=0.165）。来那度胺在PFS（p=0.153）或OS（p=0.351）方面均无获益。R-CHOP的中位随访时间为20.6个月，R2-CHOP为23.5个月，R-CHOP加BTKi为17.6个月，1年PFS率分别为73.6%、82.2%和93.3%，1年OS率分别为96.2%、93.2%和100%。3-4级不良反应包括白细胞减少、中性粒细胞减少、贫血和血小板减少，各组间无显著差异：结论：添加BTK抑制剂可提高DE-DLBCL患者的无进展生存期，尤其是晚期患者，且不会带来新的严重不良反应。结论：添加BTK抑制剂可提高DE-DLBCL患者的无进展生存期，尤其是晚期患者，但不会带来新的严重不良反应。
