Study summary

CD180 is a cell-surface protein recently identified through proteomic analysis as a potential target of interest in myeloid hematological malignancies. It may have diagnostic and monitoring potential, particularly in acute myeloid leukemia (AML).

This monocentric, non-interventional, retrospective observational study aims to characterize CD180 expression by flow cytometry in pathological hematopoietic cells, particularly in AML, and in normal hematopoietic stem and progenitor cells (CD34+ cells). The study will use residual blood and bone marrow samples collected during routine care and otherwise intended for disposal by incineration, together with relevant clinical and laboratory data.

Inclusion Criteria: * Adult patients aged 18 years or older. * Pediatric patients aged 1 to 17 years. * Patients with confirmed or suspected acute myeloid leukemia who have undergone bone marrow aspiration as part of the diagnostic or relapse assessment. * Patients whose stem cells are being assessed using a blood or bone marrow sample. * Patients and/or their legal representatives, where applicable, informed by letter of the use of residual sample material for research purposes. * No written objection documented in the medical record to the reuse of personal data for scientific research. Exclusion Criteria: * Patients and/or their legal representatives, where applicable, who have objected to the reuse of personal data for scientific research. * Samples more than 72 hours old. * Clotted samples. * Samples with insufficient volume (less than 10 microliters).

Primary outcome measure(s)

  • CD180 Expression in Normal and Pathological CD34+ Cells — During the 6-month data collection period, from January 21, 2026, to July 21, 2027.
    Percentage of CD34+ cells expressing CD180 above the levels observed in negative control populations (T lymphocytes and neutrophils), and intensity of CD180 expression measured by antibody-based fluorescence intensity.
