## TL;DR

This study analyzed 52 PCNSL patients to identify clinical features and factors affecting survival, finding that age and treatment type significantly impact outcomes.

## Contribution

The study provides updated survival data and identifies HD-MTX and auto-HSCT as beneficial treatments for PCNSL.

## Key findings

- High-risk MSKCC score and age over 60 were linked to worse survival in PCNSL patients.
- HD-MTX and auto-HSCT were associated with improved overall survival.
- Two-year and five-year PFS rates were 56.4% and 36.3%, respectively.

## Abstract

探讨原发中枢神经系统淋巴瘤（PCNSL）的临床特征、治疗方案以及预后相关因素。

纳入2013年1月至2023年12月北京大学第三医院收治的52例PCNSL患者临床资料，对患者临床特征、治疗方案以及预后相关因素进行回顾性分析。通过单因素及多因素Cox比例风险模型分析PCNSL患者无进展生存（PFS）和总生存（OS）的影响因素。

所有患者中位发病年龄为57（23～87）岁，男女比例为1.08∶1。神经功能障碍（71.2％）和颅内高压（57.7％）为常见的临床表现。肿瘤累及深部脑组织，呈多灶病变。49例可评估疗效，中位随访时间为23（95％ CI：8.6～37.4）个月，2年、5年PFS率分别为56.4％（95％CI：42.2％～68.3％）、36.3％（95％CI：17.3％～53.4％），总生存（OS）率分别为75.5％（95％CI：61.7％～87.2％）、66.0％（95％CI：43.9％～78.3％）。单因素Cox回归分析显示，年龄>60岁（HR＝3.436，95％ CI：1.008～11.710，P＝0.049）、美国纪念斯隆-凯特琳癌症中心（MSKCC）评分系统分层高危（HR＝22.130，95％ CI：4.736～103.400，P<0.001）为OS的不良预后因素，接受auto-HSCT治疗（HR＝0.223，95％ CI：0.077～0.643，P＝0.006）可延长OS期。多因素Cox回归分析结果显示，接受含大剂量甲氨蝶呤（HD-MTX）化疗（HR＝0.082，95％ CI：0.008～0.873，P＝0.038）、接受auto-HSCT治疗（HR＝0.151，95％ CI：0.030～0.747，P＝0.020）是OS的独立预后因素。

PCNSL患者中，高龄及预后危险分层高危患者预后较差。采用含HD-MTX治疗方案以及进行auto-HSCT可改善患者生存。
