Study phase:

N/A

研究设计:

连续入组 

Study design:

Sequential 

研究目的:

1.评估基线期外周血、脑脊液ctDNA对原发中枢神经系统淋巴瘤患者的辅助诊断价值,比较其敏感度、特异度及组织活检结果的一致性 2.动态监测原发中枢神经系统淋巴瘤患者治疗过程中外周血和脑脊液ctDNA水平变化,探讨其与影像学评估和无进展生存的相关性  

Objectives of Study:

1.To evaluate the diagnostic utility of baseline ctDNA from peripheral blood and cerebrospinal fluid in primary central nervous system lymphoma, comparing the sensitivity specificity and concordance with tissue biopsy. 2.Longitudinally monitoring ctDNA dynamics in peripheral blood and cerebrospinal fluid during treatment in patients with PCNSL,and examining its association with imaging evaluation and progression-free survival.
