Brief Summary:
The goal of this clinical trial is to evaluate a new combination therapy for patients with newly diagnosed Primary Central Nervous System Lymphoma (PCNSL). The main questions it aims to answer are: (1) Does the combination of Methotrexate, Rituximab, Sintilimab, and Pirtobrutinib improve the Complete Remission Rate (CRR)? (2) Is this regimen safe and tolerable for patients? Researchers will compare this interventional group to a real-world observational group (receiving standard investigator-selected treatments) to see if the new combination improves treatment response and survival.
Detailed Description:
Primary Central Nervous System Lymphoma (PCNSL) is a rare extranodal non-Hodgkin lymphoma with poor prognosis, characterized by MYD88 L265P/CD79B mutations and PD-L1/PD-L2 overexpression. Current first-line therapies based on high-dose methotrexate (HD-MTX) have limitations including high recurrence rates, poor blood-brain barrier penetration, and significant toxicity. Pirtobrutinib, a highly selective reversible BTK inhibitor, exhibits superior CNS penetration and safety profiles compared to covalent BTK inhibitors. Sintilimab (anti-PD-1) enhances anti-tumor immunity by blocking PD-1/PD-L1 axis. This study evaluates the efficacy and safety of the quadruple combination (methotrexate+rituximab + sintilimab + pirtobrutinib ) in treatment-naive PCNSL, with a real-world cohort providing comparative evidence.
