Abstract
Chronic lymphocytic leukemia (CLL) is the most common leukemia in the western world and is characterized by a highly variable clinical course. CLL can be classified into two biological subtypes, according to the presence or absence of somatic mutations in the immunoglobulin heavy-chain variable region (IgVH). IgVH mutational status is of high-clinical relevance: cases with unmutated IgVH show a less favorable course with a rapid progression, whereas cases with mutated IgVH show a stable disease and longer survival. Unfavorable prognosis is also associated with the inactivation of an important tumor-suppressor p53; these patients harbor a deletion of 17p13 and this chromosomal abnormality is often accompanied by the mutation of the second TP53 allele, which leads to the complete elimination of p53 function. Moreover, a single mutation of one of the TP53 allele also occurs in a significant proportion of CLL cases. Patients with TP53 abnormalities typically do not respond to therapy and have a median survival of less than 3 years.
