AIMS: Evaluation of serum levels of 17 cytokines and 5 adhesion molecules in patients treated for acute myeloid leukemia (AML) using biochip array technology. This approach allows multi-analytical determination from a single sample. METHODS: A total of 15 AML patients were studied. Blood samples were taken at the diagnosis (active leukemia) and at circa 6 months after completion of last chemotherapy (durable complete remission in all patients). RESULTS: Comparing cytokine and adhesion molecule levels in active leukemia and in durable complete remission, we found significant increase (P<0.01) in serum interleukin-7 (IL-7), epidermal growth factor (EGF), vascular endothelial growth factor (VEGF), and significant decrease (P<0.01) in serum E-selectin. DISCUSSION: Our results indicate that serum levels of specific cytokines and adhesion molecules (IL-7, EGF, VEGF, E-selectin) are significantly altered in patients treated for AML, reflecting activity of the disease. Further investigation is needed to establish if the changes observed in the levels of these molecules could be used as a prognostic indicator of AML.
