Summary
Brief summary (as posted)
This is a retrospective, multicenter study focused on patients with a known diagnosis of PMLBCL which experienced a CNS relapse during the course of their disease to obtain information about the clinical characteristics, the management at diagnosis and at each relapses , and the outcome of these cases. The aim of the study is to put together the large International series on CNS+ PMLBCL data, coming from 6 different countries , on clinical factors, anti-lymphoma therapy administered alone or concomitant with CNS prophylaxis , the information about the site of re biopsy when available , the dose intensity of lymphoma therapy received at relapse and the outcome of patients. Both patients treated in routine practice or within clinical trials will be considered. Moreover to better characterized the pathological features of this rare entity a central pathological review of the initial diagnosis and when available of for histological confirmed relapse will be considered.
