Orelabrutinib plus reduced-dose whole brain radiotherapy in elderly primary central nervous system lymphoma: a case report

These preliminary findings suggest that the all patients initially achieved either complete remission (CR) or partial remission (PR). Two patients maintained durable remission, whereas one patient experienced disease relapse after discontinuing orelabrutinib and switching to an alternative regimen. No significant neurotoxicity or treatment-related complications were observed. Combination of orelabrutinib and rd-WBRT may represent a safe and effective therapeutic approach for elderly patients with PCNSL who are not candidates for standard chemotherapy. Prospective clinical trials are warranted to further evaluate this approach.
