Multiple Myeloma Extramedulary Disease Samples FFPE
Discovery And Validation Of New Biomarkers In The Context Of Multiple Myeloma Extramedulary Disease
Source: ClinicalTrials.gov · Last updated 20 Mar 2026
Brief summary (registry, in English)
This observational study aims to evaluate the feasibility of assembling a retrospective cohort of formalin-fixed paraffin-embedded (FFPE) tissue samples from patients with extramedullary multiple myeloma, together with their associated clinical and pathological data. The study will determine whether these archived samples are suitable for exploratory biomarker assessment. No intervention is performed. All FFPE samples and clinical data originate exclusively from routine diagnostic procedures and will be analyzed retrospectively for research purposes.
