| Popis | T he prognostication of patients with chronic lympho- cytic leukemia (CLL) currently relies on both clinical and biological parameters (Figure 1). The prime exam- ple concerns the TP53 gene, whereby inactivation of TP53 , resulting from either a mutation or chromosome 17p deletion, is associated with a short time to progression, an early need for treatment, and an overall dismal outcome. 1,2 The presence of TP53 aberrations is also a strong predictor of treatment response, as patients carrying such lesions respond poorly to standard chemoimmunotherapy (CIT) (i.e. fludarabine, cyclophosphamide, and rituximab). 3 Although TP53 abnor- malities are infrequent at diagnosis (5%-10%), they are found in 40%-50% of advanced or therapy-refractory cases, hence underscoring the need to re-assess TP53 gene status as the dis- ease progresses and clones evolve. |
