~Del (17p) which results in the loss of TP53, is the most important prognostic marker in CLL and is associated with poor outcomes, rapid disease progression and is historically associated with resistance to standard fludarabine-based chemoimmunotherapy. The pathogenic role of del(13q) in CLL has been related to lack of B-cell proliferation control allegedly determined by deletion of the DLEU2/ MIR15A/ MIR16-1 locus, which is known to contain negative regulators of the expression of the BCL2 gene (Cimmino et al., 2005; Klein et al., 2010).

Whereas 13q deletion was a favorable prognostic factor in CLL, a large deletion of 13q was associated with poor prognosis in terms of time to first therapy (p = 0.020), progression-free survival (p = 0.05) and overall survival (p = 0.002) in BCLPD cases other than CLL. 12.
