Discovery And Validation Of New Biomarkers In The Context Of Multiple Myeloma Extramedulary Disease
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.
Inclusion: Adult patients with histologically confirmed extramedullary myeloma (excluding plasmacytoma); Availability of a representative FFPE block from a surgical specimen; Diagnosis established within the past 10 years; Availability of associated clinical and follow-up data.
Exclusion: Patients with plasmacytoma only; Insufficient or non-representative FFPE material; Missing key diagnostic or clinical data.
