Intrathoracic lymphoblastic lymphoma (LBL) is classically of T-cell lineage, but these cases of pleural B-cell LBL suggest that this is not always the case. Despite the clinical challenges involved every attempt should be made to secure a biopsy and histological diagnosis, as we move into an era of lineage-directed therapies.

B-cell acute lymphoblastic leukemia (B-ALL) is the most common form of cancer diagnosed in children. While the majority of patients survive with conventional treatment, chemotherapeutic agents have adverse effects and the potential for relapse persists even after full recovery. Given their pivotal function in anti-cancer immunity, there has been a surge in research exploring the potential of natural killer (NK) cells in immunotherapy, which has emerged as a promising avenue for treating leukemia.

Objective: To analyze the clinical characteristics and molecular biomarkers of adult T-cell lymphoblastic lymphoma (T-LBL) to identify prognostic factors, and to evaluate the efficacy of different chemotherapy regimens, providing a basis for optimizing treatment strategies for T-LBL.
Methods: A total of 89 Patients aged 18-72 years with T-LBL, confirmed via histopathological examination of lymph nodes, extranodal tissues, or bone marrow, were retrospectively included. Clinical data, treatment details, and mutational profiles were collected.

VTRNA2-1 is a polymorphically imprinted locus. The proportion of individuals with a maternally imprinted VTRNA2-1 locus is consistently approximately 75% in populations of European origin, with the remaining circa 25% having a non-methylated VTRNA2-1 locus. Recently, VTRNA2-1 hypermethylation at birth was suggested to be a precursor of paediatric acute lymphoblastic leukaemia with biomarker potential.

Solute carrier (SLC) transporters play a crucial role in facilitating the cellular uptake of various anticancer drugs, such as methotrexate (MTX). This study aimed to analyze the impact of nonsynonymous single nucleotide polymorphisms (SNPs) in , , and on MTX exposure, toxicities, and prognosis in 148 patients with acute lymphoblastic leukemia (ALL). The rs7311358 polymorphism was significantly associated with the median dose-normalized MTX concentrations at 24 h ( < .

Recent studies have demonstrated the association between constitutional ring chromosome 21 (r(21)c) and the development of B-cell acute lymphoblastic leukemia (B-ALL) with intrachromosomal amplification of chromosome 21 (iAMP21). iAMP21 acts as a driver which is often accompanied by secondary alterations that influence disease progression. Here, we report an atypical case of iAMP21 B-ALL with a unique molecular profile in the context of r(21)c.
