Classification of cases of diffuse large B-cell lymphoma (DLBCL)/high-grade B-cell lymphoma (HGBL) with MYC and BCL6 rearrangements, also known as BCL6 double hit lymphoma (DHL), is controversial. We assessed 60 cases of BCL6-DHL and compared this cohort to 224 cases of DHL with MYC and BCL2 rearrangements (BCL2-DHL) and 217 cases of DLBCL not otherwise specified. Compared with the DLBCL cohort, BCL6-DHL patients had more aggressive clinical features such as frequent extranodal involvement, high-stage disease, high IPI score and elevated serum lactate dehydrogenase level (p <0.

ALK-positive large B-cell lymphoma (ALK+ LBCL) is a rare neoplasm with an aggressive course and poor therapeutic response to the standard R-CHOP regimen. Owing to its negativity for usual B- and T-cell markers and immunopositivity for epithelial markers, it can be easily misdiagnosed if it is not contemplated. To study the clinicopathological parameters of cases of ALK+ LBCL diagnosed at our institution.

Background: Double-expressor lymphoma (DEL) has a poorer prognosis than other subtypes of diffuse large B-cell lymphoma (DLBCL). This study is a multicenter, prospective, single-arm, phase 2 clinical study initiated by investigators to evaluate the efficacy and safety of combined zanubrutinib with R-CHOP, which includes rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone for patients with DEL (stage II or more), as well as to explore factors related to efficacy preliminarily.
Methods: From November 2020 to July 2022, 48 newly diagnosed patients were enrolled.

CRLF2 rearrangements occur in >50% of Ph-like and Down syndrome (DS)-associated B-acute lymphoblastic leukemia (ALL) and induce constitutive kinase signaling targetable by the JAK1/2 inhibitor ruxolitinib under current clinical investigation. While chimeric antigen receptor T cell (CART) immunotherapies have achieved remarkable remission rates in children with relapsed/refractory B-ALL, ~50% of CD19CART-treated patients relapse again, many with CD19 antigen loss. We previously reported preclinical activity of thymic stromal lymphopoietin receptor-targeted cellular immunotherapy (TSLPRCART) against CRLF2-overexpressing ALL as an alternative approach.

Background: Recent breakthrough advances in the treatment of DLBCL, such as the antibody-drug conjugate polatuzumab vedotin, have yielded clinical survival benefit over rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) for the first time in 20 years since the advent of the rituximab era. We thus examine the outcomes of standard immunochemotherapy for DLBCL in our multi-ethnic Asian population, so as to determine the real-world clinical need to adopt new therapeutics in this disease entity.
Methods: We conducted a retrospective study involving patients (n = 1071) diagnosed with DLBCL at the National Cancer Centre Singapore from 2010 to 2022, and treated with first-line rituximab-based regimens.
