We evaluated serum levels of 17 cytokines and 5 adhesion molecules in patients with acute lymphoblastic leukemia (ALL) and in healthy subjects using biochip array technology. Our results indicate that serum levels of VCAM-1, ICAM-1, L-selectin, IL-8, IL-3, IL-4 and MCP-1 are significantly altered in patients with newly diagnosed ALL, reflecting activity of the disease. .
