PG - 529-37 LID - 10.1111/j.1365-2141.2008.07227.x [doi] AB - Immunophenotypic studies, fluorescence in situ hybridization (FISH) and conventional karyotyping were used to define the clinicobiological significance of 14q32 translocations involving the immunoglobulin gene locus (14q32/IGH) in 252 chronic lymphocytic leukaemia (CLL) patients. The following regions were studied: 13q14, centromere 12, 6q21; 11q22/ATM; 17p13/TP53, 14q32/IGH. Patients were classified as group 1 (favourable, i.e. 13q-single or normal), group 2 (intermediate risk, i.e. +12, 6q-, 1-2 anomalies), group 3 (unfavourable, i.e. 17p-, 11q-, complex karyotype), or group 4 (14q32/IGH translocation). Endpoints were treatment-free survival (TFS) and overall survival (OS). One hundred and ten patients were included in group 1, 99 in group 2, 25 in group 3 and 18 in group 4. 14q32/IGH translocation partners were identified in eight cases (BCL2 in five cases, BCL11A, CCND3 and CDK6 in one case each). group 4 showed shorter TFS versus groups 2 and 1 (25% patients treated at 2 months vs. 12 (P = 0.02) and 20 months (P = 0.002), respectively) and shorter OS (25% patients dead at 18 months versus 50 (P = 0.0003) and >60 months (P < 0.0001) respectively. The 14q32/IGH translocation maintained prognostic significance at multivariate analysis on TFS (P = 0.025) and OS (P < 0.001), along with advanced stage and CD38+. These findings show that the 14q32/IGH translocation predicts for an unfavourable outcome in CLL and that this cytogenetic subset might be included as a separate entity in a hierarchical cytogenetic classification of CLL.
