PG - 523-7 LID - S2210-7762(12)00152-4 [pii] LID - 10.1016/j.cancergen.2012.05.011 [doi] AB - Immunoglobulin heavy chain translocations (t(IGH@)) are suggested to portend a poor prognosis in chronic lymphocytic leukemia (CLL). To determine the clinical significance of a t(IGH@) on CLL-specific cytogenetic abnormalities, we analyzed the outcomes of 142 CLL patients referred for fluorescence in situ hybridization (FISH) analysis with our standard FISH panel, which includes testing for a t(IGH@). Whereas patients with unfavorable (deletion 17p, deletion 11q) and intermediate (trisomy 12, normal FISH) cytogenetics with concomitant t(IGH@) had similar median treatment-free survival (TFS) as those without a t(IGH@), patients with deletion 13q (del13q) and a t(IGH@) had significantly worse TFS than those without a t(IGH@): median TFS 4.7 versus 8.0 years, P = 0.03 (hazard ratio 4.21, 95% confidence interval 1.06-16.69 y, P = 0.04 in multivariate analysis after adjusting for age, sex, Rai stage, and white blood cell count). The presence of a t(IGH@) further stratified patients with del13q into two prognostic entities, whereby outcomes of those with coexistent del13q and a t(IGH@) were similar to outcomes of those with high risk cytogenetics. Knowledge of the t(IGH@) status in CLL is therefore of clinical importance, as del13q patients with concomitant t(IGH@) may not retain the previously expected favorable outcome.
