These patients also carry a poor prognosis akin to patients with del (17p). This significant 13q14 deletion contributes to CLL's pathogenesis and paves the way for CLL treatment, hence affecting the prognosis of the affected patients.

Prognostic Factors in CLL - CLL Society 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. The authors have declared that no competing interests exist. These cases often demonstrate atypical morphological and immunophenotypic features, high proliferative rates, unmutated immunoglobulin heavy chain variable region genes, and a high frequency of NOTCH1 mutation. However, low-dose radiation may be used if you have an enlarged spleen or swollen lymph nodes in a specific area. In the low-cell variant, progression into CLL is rare.

We performed fluorescence in situ hybridization (FISH) studies with 13q locus-specific LSI-D13S25 and LSI-RB1 probes. Patients with chronic lymphocytic leukemia (CLL) with 13q deletion as the sole cytogenetic abnormality usually have a favorable outcome, but the frequency of the 13q14 deletion and its impact on the outcome of other B-cell chronic lymphoproliferative disorders (BCLPDs) remain unclear.
