We have correlated histologic type of Hodgkin's disease, degree of Hodgkin and Reed-Sternberg cell infiltration, percentage of Hodgkin and Reed-Sternberg cell positivity for latent membrane protein, immunophenotype of Hodgkin and Reed-Sternberg cells, and immunoglobulin heavy chain (IgH) gene rearrangements detected by polymerase chain reaction (PCR) in 56 unselected Hodgkin's disease cases.
Evaluation diagnostic usefulness of immunoglobulin light chains (Igκ, Igλ) and incomplete IGH D-J clonal gene rearrangements in patients with B-cell non-Hodgkin lymphomas using BIOMED-2 protocol.
In conclusion, we present the first examples of molecularly verified IgH-associated translocations in HL, which also show that BCL2/IGH or CCND1/IGH translocations can represent early steps in the pathogenesis of composite HL/FL or HL/MCL.
Immunoglobulin heavy chain (IgH) gene rearrangement analysis was performed on 27 fine needle aspiration (FNA) specimens (13 reactive hyperplasia, 11 B cell non-Hodgkin's lymphoma (B-NHL), one Hodgkin's disease and two suspicious of non-Hodgkin's lymphoma).
By using a polymerase chain reaction (PCR) and consensus primers for the V and J regions of the immunoglobulin heavy chain (IgH) gene, the authors were able to detect B-cell clonality in 9 of 18 (50%) frozen samples of HD analyzed.
We have therefore investigated somatic mutation of the lg heavy chain (IgH) genes among 17 cases of B-ALCL to clarify whether there is a difference in characteristic and origin of tumor cells between B-ALCL, B-HD and DLBCL.
In a subset of the cHL, the IGH gene rearrangement analysis might be useful for diagnosis, but can lead to confusion between cHLs and non-Hodgkin lymphomas if used as a discriminative criterion.
Combined study of IGH and IGK rearrangement according to BIOMED-2 protocols improves clonality detection rate (up to 25% of cases) in HL, even when working on non-microdissected FFPE tissue.
We have studied isolated H/RS cells from four cases of lymphocytic predominance (LP) HD and six cases of nodular sclerosis (NS) HD and assayed the cells for immunoglobulin heavy chain (IgH) gene rearrangement by the polymerase chain reaction (PCR).
Improved clonality detection in Hodgkin lymphoma using a semi-nested modification of the BIOMED-2 PCR assay for IGH and IGK rearrangements: A paraffin-embedded tissue study.
Based on the presence of T cell receptor-beta (TcR-beta) gene rearrangements in L428 and HDLM-1 cells, the expression of CD2 in HDLM-1 cells, and the presence of immunoglobulin heavy-chain (IgH) gene rearrangement in KM-H2 cells, some researchers have concluded that these long-term cell lines derived from patients with Hodgkin's disease are lymphoid in nature.
Molecular analysis of the IgH gene in 212 cases of Hodgkin's disease: correlation of IgH clonality with the histologic and the immunocytochemical features.
