This prospective, non-randomized diagnostic interventional study evaluates cognitive impairment in patients with diffuse large B-cell lymphoma (DLBCL) treated at the Institute of Oncology Ljubljana. Chemotherapy regimens are administered according to clinical indication and are not assigned by the study protocol.
The research intervention consists of structured neurocognitive assessments and biomarker analyses performed at predefined time points during treatment and follow-up. Cognitive function will be assessed at baseline, after the first chemotherapy cycle, and 12 months after treatment initiation. In patients receiving intrathecal chemotherapy, cerebrospinal fluid (CSF) biomarkers will be analyzed using samples collected during clinically indicated lumbar punctures.
The study aims to characterize the frequency, severity, and trajectory of cognitive impairment and to identify clinical and biological predictors of treatment-associated cognitive changes in patients with DLBCL.
