Brief summary
In view of the synergistic effects of rituximab, zanubrutinib, and lenalidomide and severe complications caused by current standard chemotherapy regimens in Patients for primary or secondary CNS lymphoma, we intend to conduct a prospective clinical study to evaluate the efficacy and toxicity of Rituximab, Zanubrutinib in combination with Lenalidomide. Besides, the efficacy of Zanubrutinib or Lenalidomide in maintenance was also compared.
Interventions

Induction therapy: Rituximab 375 mg / m2, day 1, Zanubrutinib 160 mg bid, orally, Lenalidomide 25mg QD, orally on day 1-21, 28 days as a course of treatment, 8 courses of treatment.
DRUGLenalidomide, Zanubrutinib
Maintenance therapy: Lenalidomide: 25mg qd (adjusted according to hectogram condition) or Zanubrutinib 160 mg bid. Continuously use for 2 years or until disease progression
DRUGLenalidomide
