Classical Hodgkin lymphoma is characterized by recurrent copy number gains of the short arm of chromosome 2.
Hodgkin- and Reed-Sternberg (HRS) cells microdissected from 41 classical Hodgkin lymphomas (cHL) of 40 patients comprising 8 lymphocyte-rich (cHL-LR), 16 nodular sclerosis (cHL-NS), 15 mixed-cellularity (cHL-MC), and 2 lymphocyte-depletion (cHL-LD) subtypes were analyzed by comparative genomic hybridization for recurrently imbalanced chromosomal subregions. Chromosomal gains most frequently inv...
متن کاملGenome-wide copy number analysis of Hodgkin Reed-Sternberg cells identifies recurrent imbalances with correlations to treatment outcome.
In classical Hodgkin lymphoma (cHL) the mechanisms underlying primary refractory disease and relapse remain unknown. To gain further insight into cHL pathogenesis and genomic changes linked to treatment response, we studied 53 cHL patients by array comparative genomic hybridization, including 23 patients whose primary treatment failed, using DNA from microdissected HRS cells. Copy number altera...
متن کاملRecurrent involvement of the REL and BCL11A loci in classical Hodgkin lymphoma.
Comparative genomic hybridization studies have shown gains in chromosome region 2p as the most common imbalance in classical Hodgkin lymphoma (cHL). The minimal region of gain contained 2 candidate oncogenes, REL and BCL11A. This study examined the involvement of REL and BCL11A loci in 44 primary cases of cHL by combined immunophenotyping and interphase cytogenetics (FICTION). A median 2p13 cop...
متن کاملGenomic imbalances including amplification of the tyrosine kinase gene JAK2 in CD30+ Hodgkin cells.
Comparative genomic hybridization was applied for a comprehensive screening of frequently occurring net gains and losses of chromosomal subregions in small populations of CD30+ Hodgkin cells and their morphological variants. In 12 Hodgkin's lymphomas, recurrent gains were detected on chromosomal arms 2p, 9p, and 12q (in six, four, and five tumors, respectively) and distinct high-level amplifica...
متن کاملClassical Hodgkin lymphoma is associated with frequent gains of 17q.
The etiology of Hodgkin lymphoma (HL) is poorly understood, and studies of the genetics of this disease have been hampered by the scarcity of the Hodgkin and Reed-Sternberg (HRS) cells within tumors. To determine whether recurrent genomic imbalances are a feature of HL, CD30-positive HRS cells were laser-microdissected from 20 classical Hodgkin lymphomas (cHLs) and four HL-derived cells lines a...
