MYC, BCL2, and BCL6 rearrangements are clinically important events of diffuse large B-cell lymphoma (DLBCL). The ability and clinical value of targeted next-generation sequencing (NGS) in the detection of these rearrangements in DLBCL have not been fully determined.

Mar 21, 2013 · MYC rearrangements occur in 5% to 10% of diffuse large B-cell lymphomas (DLBCL) and confer an increased risk to cyclophosphamide, hydroxydaunorubicin, oncovin, and prednisone (CHOP) and rituximab (R)–CHOP treated patients.

Jan 19, 2017 · High-grade B-cell lymphomas (HGBLs) with MYC and BCL2 and/or BCL6 rearrangements, so-called “double-hit” lymphomas (HGBL-DH), are aggressive lymphomas that form a separate provisional entity in the 2016 revised World Health Organization Classification of Lymphoid Tumors.

Nov 15, 2013 · Diffuse large B cell lymphomas involving co-expression of MYC protein with BCL2 or BCL6 have a significantly lower survival rate compared to the patients with single protein expression of BCL2 or BCL6 as well as co-expression of BCL2 and BCL6.

Double/triple-hit lymphomas (DHL/THL) account for 5–10% of diffuse large B cell lymphoma (DLBCL) with rearrangement of MYC and BCL2 and/or BCL6 resulting in MYC overexpression. Despite the poor prognosis of DHL, R-CHOP chemotherapy remains the treatment backbone and new targeted therapy is needed.

May 3, 2018 · High-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements (HGBL-DH/TH) is a newly defined entity in the latest World Health Organization Classification. Accurate diagnosis would appear to mandate fluorescence in situ hybridization (FISH) for all tumors with diffuse large B-cell lymphoma (DLBCL) morphology.

Double-hit (DH) lymphomas with MYC and either BCL2 (DH-BCL2/MYC) or BCL6 (DH-BCL6/MYC) rearrangements are considered very aggressive, many of which are now included in the category B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma (DLBCL) and Burkitt l …

Classification of cases of diffuse large B-cell lymphoma (DLBCL)/high-grade B-cell lymphoma (HGBL) with MYC and BCL6 rearrangements, referred to here as BCL6 double-hit lymphoma (DHL), is controversial.

In this study, we assessed rearrangements and expression of MYC, BCL2 and BCL6 in 898 patients with de novo diffuse large B-cell lymphoma treated with standard chemotherapy (cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab).

Oct 14, 2024 · High-grade B-cell lymphoma with MYC, BCL2 and/or BCL6 rearrangements (HGBCL-DH/TH) is a group of aggressive lymphomas that are associated with poor outcomes when treated with R-CHOP [1,...
