Tailoring of chronic lymphatic leukemia therapy

Chronic lymphocytic leukemia (CLL) remains an incurable disease, with all patients who require therapy destined to relapse and understanding of the pathophysiology of chronic lymphocytic leukemia has advanced significantly. It is now clear that chronic lymphocytic leukemia is a relatively proliferative disorder that requires the help of its microenvironment to be maintained and to progress. The stimulation of the chronic lymphatic leukemia cell occurs in most, if not all, patients through antigen stimulation via the B cell receptors. In addition, there is now a appreciation of the role of the p53 pathway leading to chemoresistance and the elucidation of the molecular and intracellular signaling mechanisms of disease is just beginning to facilitate the development of several targeted small molecules that promise to revolutionize the treatment of Chronic lymphocytic leukemia.
