PG - 115 LID - 10.1007/s12032-014-0115-4 [doi] AB - The mixed lineage leukemia (MLL) gene on chromosome region 11q23 is frequently involved in chromosomal translocations associated with various human hematologic malignant neoplasms. The aim of this study was to investigate the profile of 11q23 abnormalities in adult Chinese patients with hematological malignancies. In this study, 11q23 abnormalities were detected by cytogenetic and fluorescence in situ hybridization (FISH) approaches in 77 out of a total of 2,404 adult Chinese patients with leukemia, lymphoma, and myelodysplastic syndrome (MDS). 11q23 abnormalities were found in 5.31 % of the acute myeloid leukemia (AML) cases, 5.71 % of the acute lymphoid leukemia (ALL) cases, 2.94 % of lymphoma cases, and 1.24 % of MDS cases. Of the patients with 11q23 abnormalities, 59.74 % showed rearrangement or deletion of the MLL gene by FISH; a novel 11q23 rearrangement, der(6)t(6;11)(q23;q23), was discovered in one case. Our data showed that t(11;19)(q23;p13.1) was the most frequent translocation in AML patients and t(4;11)(q21;q23) was the most frequent translocation in ALL patients. FLT-ITD mutations were detected in three out of 33 AML patients with 11q23 abnormalities (9.09 %). The Kaplan-Meier survival analysis further showed that the 11q23 aberration was a poor prognostic factor for AML. The median survival times in the 11q23 aberration subgroup, the normal karyotype subgroup, and the subgroup with other abnormalities were 7.4, 11.3, and 16.8 months, respectively (P = 0.0464). Our study found one novel 11q23 rearrangement, der(6)t(6;11)(q23;q23), and demonstrated the profile of 11q23 abnormalities in adult Chinese patients with hematological malignancies.
