## TL;DR

Adding BTK inhibitors to R-CHOP treatment improves outcomes for a specific type of lymphoma without major safety issues.

## Contribution

This study demonstrates improved efficacy and acceptable safety of BTK inhibitors combined with R-CHOP in double-expressor DLBCL.

## Key findings

- BTKi+R-CHOP group had higher ORR (94.3%) and CR rate (91.4%) compared to R-CHOP alone.
- BTKi+R-CHOP showed significantly better 2-year PFS (85.1%) and OS (94.3%) than R-CHOP.
- Adverse events were manageable, with no fatal bleeding or cardiovascular events observed.

## Abstract

探讨布鲁顿酪氨酸激酶抑制剂（BTKi）联合R-CHOP方案治疗初诊双表达（DE）弥漫大B细胞淋巴瘤（DLBCL）的疗效与安全性。

回顾性分析2021年6月至2024年6月期间南京医科大学第一附属医院收治的95例确诊为DLBCL且免疫组织化学染色判断MYC蛋白表达≥40％，BCL2蛋白表达≥50％的DE患者临床资料。其中35例接受BTKi（泽布替尼/奥布替尼/阿可替尼）联合R-CHOP方案治疗（BTKi+R-CHOP组），60例接受R-CHOP方案治疗（R-CHOP组）。观测指标包括客观缓解率（ORR）、完全缓解（CR）率、无进展生存（PFS）、总生存（OS）以及安全性评估。

BTKi+R-CHOP组患者中位年龄61（29～73）岁。诱导治疗结束时，BTKi+R-CHOP组ORR和CR率均高于R-CHOP组（ORR：94.3％对71.7％，P＝0.008；CR率：91.4％对65.0％，P＝0.006）。中位随访30（6～47）个月，BTKi+R-CHOP组1年及2年PFS率分别为88.5％（95％ CI：78.5％～99.8％）和85.1％（95％ CI：73.8％～98.1％），1年及2年OS率均为94.3％（95％ CI：86.9％～100％）。R-CHOP组1年、2年PFS率分别为61.7％（95％ CI：50.5％～75.3％）和48.8％（95％CI：37.4％～63.6％）；1年、2年OS率分别为80.0％（95％ CI：70.5％～90.8％）和65.1％（95％ CI：53.7％～78.8％）。两组生存差异均具有统计学意义（PFS：P＝0.002；OS：P＝0.010）。亚组分析显示，BTKi+R-CHOP组在不同临床特征患者中均获得较高缓解率，各亚组ORR均>85％。BTKi联合R-CHOP方案治疗期间≥3级不良事件主要为中性粒细胞减少症（28.6％）和肺部感染（14.3％），无致死性出血或心血管事件。

BTKi联合R-CHOP方案可显著提高DE-DLBCL患者的缓解率并增加生存获益，安全性可控。
