Purpose of review: The remarkable progress witnessed over the past few years in the diagnosis, prognosis, and therapy of chronic lymphocytic leukemia has profoundly changed the clinical approach to this disease. This review focuses on the most recent advances in the diagnostic and prognostic examination of patients with chronic lymphocytic leukemia, with particular emphasis on their implications in clinical management, taking into account the broadening of the therapeutic possibilities available today.
Recent findings: Through the biologic improvements achieved during the past few years it is now possible to effectively stratify chronic lymphocytic leukemia patients prognostically at presentation on the basis of several laboratory parameters. Furthermore, the availability of purine analogs and monoclonal antibodies and the extension of autografting and allografting procedures have allowed the achievement of higher response rates, including molecular remissions. With the aim of investigating whether early and aggressive treatment intervention may improve the survival of patients with a poor prognosis, new therapeutic trials have been specifically designed.
Summary: A complete biologic and clinical examination now allows the establishment of a correct diagnostic characterization of patients with chronic lymphocytic leukemia and to identify patients with early disease with a different prognostic likelihood. Multicenter prospective trials, in which the enrolled patients are stratified and treated according to their prognostic risk, will determine the best treatment for the different categories of patients. It is likely that in the near future each chronic lymphocytic leukemia patient can be offered a targeted treatment algorithm based on the clinical and biologic characteristics at presentation.
