Multiple Myeloma Extramedulary Disease Samples FFPE
Condition(s) studied
Study summary
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.
Eligibility
Primary outcome measure(s)
- Feasibility of cohort inclusion based on availability of FFPE tissue and confirmed extramedullary disease. — Baseline
Number of participants who meet both criteria: * confirmation of extramedullary disease using predefined clinical and histopathological criteria, and * availability of an adequate FFPE tissue block suitable for inclusion. Feasibility will be quantified by reporting the proportion of eligible participants among all patients screened for potential inclusion.
