Testing for t(3;8) in MYC/BCL6 re-arranged large B cell lymphoma identifies a high risk subgroup with inferior survival. (PubMed, Blood)

A reciprocal t(3;8) BCL6::MYC fusion is common in large B cell lymphoma (LBCL) with MYC and BCL6 disruption. These pseudo-double hit cases are not adverse, whereas t(3;8) negative MYC/BCL6 lymphoma has an inferior prognosis relative to other MYC-rearranged LBCL.

Latent Epstein-Barr virus infection collaborates with Myc over-expression in normal human B cells to induce Burkitt-like Lymphomas in mice. (PubMed, PLoS Pathog)

These results show that latent EBV infection collaborates with Myc over-expression to induce BL-like human B-cell lymphomas in mice. As NF-κB signaling retards the growth of EBV-negative BLs, Myc-mediated repression of LMP1 may be essential for latent EBV infection and Myc translocation to collaboratively induce human BLs.

Comparison of genomic alterations in Epstein-Barr virus-positive and Epstein-Barr virus-negative diffuse large B-cell lymphoma. (PubMed, Cancer Med)

Our results confirm that genomic alteration differs significantly between EBV-posDLBCL and EBV-negDLBCL, and reveal new genetic alterations in EBV-posDLBCL. The positive correlation of c-MET and PD-L1/c-Myc expression may be involved in the pathogenesis of EBV-posDLBCL, which is should be explored prospectively in trials involving MET-directed therapies.

C-Myc protein expression indicates unfavorable clinical outcome in surgically resected small cell lung cancer. (PubMed, World J Surg Oncol)

Our study provides insights into the clinical aspects of Myc family members in surgically resected SCLC tumors. Notably, besides showing that positivity of Myc family members varies across the patients, we also reveal that C-Myc protein expression independently correlates with worse survival outcomes. Further studies are warranted to investigate the role of Myc family members as potential prognostic and predictive markers in this hard-to-treat disease.

Comparing Clinical Characteristics and Outcomes of MYC and BCL6 Double Hit Lymphoma (DHL-BCL6) with Other Aggressive B-Cell Lymphomas: Understanding the Impact of New Who and International Consensus Classifications (ASH 2023)

Patients with DHL-BCL6 were younger at diagnosis (median 60 years), had more extranodal site involvement (40%), more often stage III/IV disease (70%), and more often treated with a higher intensity regimen than R-CHOP (69%) compared to DLBCL,NOS and MYC-R DLBCL... Our data support separating DHL-BCL6 from DHL-BCL2 as these patients form a unique subgroup with some clinical characteristics comparable to both DLBCL, NOS as well as HGBL, NOS and DHL-BCL2 subtypes. In this cohort, clinical outcomes are more comparable to DLBCL, NOS than DHL-BCL2 or HGBCL, NOS. More frequent use of intensive chemotherapy in DHL-BCL6 compared with DLBCL may account for this finding, although larger multicenter studies are needed.

With a preliminary diagnosis of primary cutaneous DLBCL, positron emission tomography (PET) scan was conducted that showed intense uptake in the groin lymph nodes and multifocal femur uptake concerning for osseous marrow involvement. Accordingly, a diagnosis of systemic DLBCL was made. The findings of CD5 positivity, dual expression of BCL-2 and C-Myc, and markedly elevated Ki-67 proliferative index are associated with a worse clinical outcome. The cutaneous presentation and requirement of interdisciplinary collaboration highlight the importance of clinicopathologic correlation for accurate diagnosis. Poster type: Poster Defense

Development of a Prognostic Scoring System using MYC Expression and Soluble Interleukin Receptor -2 level for Diffuse Large B-cell Lymphoma. (PubMed, Yonago Acta Med)
