Diagnosing and treating chronic lymphocytic leukemia in 2009

Abstract

Over the past decade, major breakthroughs have been made in both the molecular understanding and the treatment of chronic lymphocytic leukemia (CLL). In this article, old and new concepts of CLL biology are explored and insights into the relevance of the newer prognostic factors are discussed. The therapeutic landscape has changed dramatically with the advent of purine analogs, monoclonal antibodies, and combination therapy. As opposed to older agents, these new therapies commonly yield complete remissions. This improvement has spurred a debate as to new goals in treating CLL patients.
