## TL;DR

This study shows that combining bendamustine with anti-CD20 monoclonal antibodies is effective and safe for older patients with indolent B-cell non-Hodgkin lymphoma.

## Contribution

The study provides real-world evidence on the efficacy and safety of bendamustine plus anti-CD20 monoclonal antibodies in elderly B-iNHL patients.

## Key findings

- The overall response rate was 92.0% with 54.3% achieving complete remission.
- The 2-year progression-free survival rate was 87.5% and overall survival rate was 83.2%.
- 33.3% of patients experienced grade 3 or higher adverse events, primarily infections and neutropenia.

## Abstract

评估苯达莫司汀联合抗CD20单抗一线治疗老年惰性B细胞非霍奇金淋巴瘤（B-iNHL）患者的疗效与安全性。

回顾性分析2019年12月1日至2024年4月20日期间在江苏省淋巴瘤协作组16家医院就诊的159例老年B-iNHL患者应用苯达莫司汀联合抗CD20单抗（利妥昔单抗或奥妥珠单抗）治疗的疗效及安全性。其中139例（87.4％）应用BR（苯达莫司汀+利妥昔单抗）方案治疗，20例（12.6％）应用BG（苯达莫司汀+奥妥珠单抗）方案治疗。

159例患者中男101例（63.5％）、女58例（36.5％），中位年龄为69（60～84）岁。138例（86.8％）患者可评估疗效，其中75例（54.3％）患者达完全缓解，52例（37.7％）患者达部分缓解，总有效率为92.0％。中位随访24（4～64）个月，患者无进展生存率为（87.5±3.0）％，总生存率为（83.2±3.3）％。死亡的27例患者中，仅6例（22.2％）伴有疾病进展。每周期苯达莫司汀中位应用剂量为73.0（50.8～89.7）mg·m−2·d−1，第1、2天用药。53例（33.3％）患者出现3级及以上的不良反应，感染（30例，18.9％）发生率最高，其次是中性粒细胞减少（24例，15.1％）。

真实世界老年B-iNHL患者一线应用苯达莫司汀联合抗CD20单抗疗效较好，安全性可控，耐受性较好。
