Science Saturday: New genetic test classifies lymphomas

The current diagnostic tools in a pathologist's arsenal sometimes cannot provide a clear distinction between primary mediastinal large B-cell lymphoma (one of the few lymphomas more common in younger women) and diffuse large B-cell lymphoma, the most common type of non-Hodgkin's lymphoma overall. This may occasionally give rise to diagnostic inaccuracy in routine practice and could leave [...]

Authors: Bond DA, Alinari L, Maddocks K Abstract Mantle cell lymphoma (MCL) is a heterogeneous and uncommon non-Hodgkin lymphoma that affects predominantly older patients and often is associated with an aggressive clinical course. MCL relies upon B-cell receptor signaling through Bruton tyrosine kinase (BTK); therefore, the development of the BTK inhibitors ibrutinib and acalabrutinib represents a therapeutic breakthrough. In this review, we provide a summary of the efficacy and safety data from the landmark trials of single-agent ibrutinib and acalabrutinib that led to US Food and Drug Administration approval of t...

Lymphomas are the heterogeneous group of malignant diseases characterized by proliferation of malignant lymphoid cells or their precursors. Lymphomas are the ninth most common cancer worldwide and constitute 3.2% of malignant tumor. Lymphomas are generally classified to two main categories: Hodgkin's lymphomas (HL) and the non-Hodgkin lymphomas (NHL), and about 90% are NHL. Non-Hodgkin lymphoma represents 4.3% of all new cancer cases in the U.S. and the ninth most common cancer in male patient of Taiwan.

Conclusion: Our combined genetic and functional approach suggests that the altered level of Hsp70 is a correlate of 8.1AH-mediated AIDS-NHL. Further investigation of the Hsp70 gene cluster and nearby loci that are tagged by A-G-A-C could better elucidate the genetic determinants of the malignancy.

Natural killer/T-cell lymphoma (NKTCL) is a rare and aggressive subtype of non-Hodgkin's lymphoma that is associated with a poor outcome. Noncoding RNAs (ncRNAs), which account for 98% of human RNAs, lack the function of encoding proteins but instead have the important function of regulating gene expression, including transcription, translation, RNA splicing, editing, and turnover. However, the roles and mechanisms of aberrantly expressed noncoding RNAs in NKTCL are not fully clear. Aberrant expressions of miRNAs affect the PI3K/AKT signaling pathways (miR-21, miR-155, miR-150, miR-142, miR-494), NF-ĸB (miR-146a, miR-155)...

Mantle cell lymphoma (MCL) is a unique type of non-Hodgkin lymphoma characterized by the overexpression of cyclin D1. MCL patients typically live for years but experience multiple relapses. Acalabrutinib is a novel second-generation oral Bruton tyrosine kinase inhibitor approved by the US Food and Drug Administration for relapsed MCL based on a clinical trial demonstrating an overall response rate of 81%. It provides a valuable new treatment option for MCL patients and is now being tested upfront.

Danny Feltwell Jr, 10, suffered from non-Hodgkin lymphoma. A bone marrow transplant treated his relapse, but then he got graft-versus-host disease. An experimental treatment has him back to pitching.

ConclusionsAlthough it is still not possible to specifically define the best PET-based predictor (i.e. SUVmax, TLG, MTV), FDG-PET is a promising tool for a more accurate and individualized selection of NHL patients candidates to RIT. The availability of FDG  PET examinations in homogenous group of patients included in already completed clinical trials might be used in the next future also to specifically assess the prognostic value of baseline FDG PET in patients treated with RIT based on the study design.

Today, the U.S. Food and Drug Administration granted accelerated approval to Polivy (polatuzumab vedotin-piiq), in combination with the chemotherapy bendamustine and a rituximab product (a combination known as "BR"), to treat adult patients with diffuse large B-cell lymphoma (DLBCL) that has progressed or returned after at least two prior therapies. Polivy is a novel antibody-drug conjugate, and DLBCL is the most common type of non-Hodgkin lymphoma.

CONCLUSIONS: We showed that BS mean values follow the ingravescence disease status towards the two main lines of progression to cancerous conditions; it could represent an additional useful tool in the management of screening and/or follow-up. PMID: 31173301 [PubMed - in process]
