## TL;DR

This study analyzes the clinical features and outcomes of follicular lymphoma patients with bone marrow involvement, finding that R-CHOP treatment is less effective and certain factors worsen prognosis.

## Contribution

The study identifies specific clinical and treatment-related factors affecting prognosis in follicular lymphoma with bone marrow invasion.

## Key findings

- R-CHOP treatment had a lower complete remission rate compared to other therapies.
- FLIPI score, chromosomal abnormalities, and treatment type were independent poor prognostic factors for progression-free survival.
- Disease progression within 24 months was the only independent factor affecting overall survival.

## Abstract

总结伴有骨髓侵犯的滤泡性淋巴瘤（FL）患者临床特征及预后，并对治疗模式进行探讨。

纳入2013年1月至2022年12月中国医学科学院血液病医院连续收治的183例伴有骨髓侵犯且接受正规治疗的FL患者。回顾性收集并分析患者临床资料，采用Kaplan-Meier法及Cox回归模型进行生存预后的单因素及多因素分析。

中位年龄48（19～78）岁，男女比例0.9∶1。所有患者均有骨髓侵犯，LDH升高比例为27.8％，淋巴细胞计数>5×109/L比例为42.1％，染色体异常及淋巴组织Ki-67指数≥30％比例分别为18.4％及48.6％；不同亚组比较：强化治疗组的淋巴细胞计数>5×109/L、受累淋巴结数目≥5个以及发生骨髓染色体异常比例，均较R-CHOP（利妥昔单抗+环磷酰胺+阿霉素+长春地辛+泼尼松）组及核苷类似物（包括CD20单抗联合氟达拉滨及苯达莫司汀）组更高（均P<0.05）。R-CHOP组完全缓解率为39.1％，较强化治疗组（55.1％）及核苷类似物组（62.5％）低（P＝0.042）。生存分析：滤泡性淋巴瘤国际预后指数（FLIPI）高危［HR=1.910（95％ CI 1.036～3.522），P=0.038］、染色体异常核型［HR＝2.666（95％ CI 1.333～5.331），P＝0.006］以及R-CHOP方案治疗［HR＝2.287（95％ CI 1.140～4.591），P＝0.020］被证实为影响无进展生存（PFS）的独立不良预后因素；而24个月内疾病进展（POD24）为影响总生存的唯一独立不良预后因素［HR＝9.581（95％ CI 3.000～30.593），P<0.001］。

伴有骨髓侵犯的FL患者容易合并淋巴细胞计数增高、染色体异常及淋巴组织Ki-67指数增高等临床特征，FLIPI评分、染色体异常核型以及不同治疗方案均为影响PFS的不良预后因素。对于这部分患者，R-CHOP方案疗效欠佳。
