To evaluate the intracranial delivery of BTK inhibitor(BTKi), patient-derived PCNS-LBCL xenografted mice models were treated with highly-selective BTKi orelabrutinib, either monotherapeutically or in combining with methotrexate...The mutations in CSF circulating tumor DNA (ctDNA) rather than plasma-ctDNA were more consistent to those in tumor tissue, indicating that CSF-ctDNA is a useful tool for monitoring PCNS-LBCL. In summary, our data provided the molecular rationale as well as clinical evidences that incorporation of BTKi into frontline induction therapy is a promising strategy for ND PCNS-LBCL.
