Patients with early stage chronic lymphocytic leukemia: new risk stratification based on molecular profiling

Leuk Lymphoma. 2011 Jul;52(7):1394-7. doi: 10.3109/10428194.2011.578311.

Abstract

We investigated molecular and biological parameters reflecting the biology of chronic lymphocytic leukemia (CLL) that may help us to predict the time to first treatment (TTT). A group of 33 patients with newly diagnosed CLL (Binet stage A) were analyzed. We developed a new scoring system based on the serum levels of β(2)-microglobulin (β(2)M) and vascular endothelial growth factor (VEGF) and the expression of lipoprotein lipase (LPL). Patients with a score of 0 had a TTT of 58.4 months, while patients with a score of 3 (increased levels of β(2)M, LPL, and VEGF) had a significantly shorter TTT of only 10.6 months (p < 0.0001).
