Value of Chemokine Receptor CXCR4 Imaging for Diagnosis and Prognostic Evaluation in Lymphoproliferative Diseases

Summary

Chemokine receptor CXCR4 is normally expressed on T-lymphocytes, B-lymphocytes, monocytes, macrophages, neutrophils and eosinophils as well as hematopoietic stem and progenitor cells (HSPC) in the bone marrow. 68Ga-Pentixafor PET/CT represents a promising method for the in vivo assessment of the CXCR4 expression status in cancer patients, especially in hematologic malignancies. This prospective study is going to investigate whether metabolic characterization by 68Ga-Pentixafor PET/CT may be superior for diagnosis, risk stratification, and the prognostic evaluation in lymphoproliferative diseases.
