Brief Summary
The study is a prospective clinical study which investigates the use of new diagnostic methods to localize aggressive lymphoma involving the central nervous system(CNS). By measuring cell-free tumor DNA and metabolomics in cerebrospinal fluid and blood in patients with systemic Diffuse Large B-cell Lymphoma the investigators aim to improve the diagnostic certainty of an impending relapse of lymphoma in CNS.

Outcome Measures
Primary Outcomes (1)
CSF tumor cfDNA and metabolite detectability and cytological/flow cytometric confirmation of CNS lymphoma at the time of diagnosis and relapse
Two years
Secondary Outcomes (10)
Progression free survival, PFS (time between inclusion and progression or relapse or beginning of a new treatment)
Two years
Overall survival, OS (time between inclusion and death)
Two years
Comparison of tumor cfDNA and metabolite levels and composition in CSF with levels in plasma at the time of diagnosis and relapse
Two years
For patients with both a pre- and a post-treatment CSF sample: correlation of cfDNA/metabolite levels pre-treatment to post-treatment with OS and risk of relapse.
Two years
Correlation of tumor cfDNA and metabolite levels and composition in CSF and patient survival at the time of diagnosis and relapse
Two years
- +5 more secondary outcomes
Eligibility Criteria
See above
You may qualify if:
- Verified or suspected primary CNS lymphoma or verified or suspected DLBCL relapsed in the CNS
- Treatment of the relapse not initiated (except pretreatment with corticosteroids)
- Age ≥ 18 years
- Patient must consent to genetic and metabolomic analysis of their cancer
- Written informed consent
You may not qualify if:
- Evidence of a CNS mass creating mass-effect or midline shift such that lumbar puncture is contraindicated
- Other contraindications to lumbar puncture according to local guidelines
- Other previous or current hematological malignancy
- Prior treatment for CNS disease (except CNS prophylaxis in first line lymphoma treatment)
- Known CNS autoimmune or inflammatory disease
- Known HIV infection
- Patient is currently receiving treatment for DLBCL
- Study 1
- Previously diagnosed histologically documented DLBCL
- Verified relapsed DLBCL
- ≥ 1 prior DLBCL treatments
- Treatment of the relapse not initiated (except pretreatment with corticosteroids)
- Being able to undergo standard assessment ( eg, Fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG-PET), MRI of the neuroaxis and bone marrow biopsy)
- Tumor biopsy and/or bone-marrow biopsy used for diagnosis available
- Age ≥ 18 years
- +34 more criteria
