Article Abstract

Natural killer/T cell lymphoma (NKTCL) is an aggressive and heterogeneous entity of non-Hodgkin lymphoma, strongly associated with Epstein-Barr virus (EBV) infection. To identify molecular subtypes of NKTCL based on genomic structural alterations and EBV sequences, we performed multi-omics study on 128 biopsy samples of newly diagnosed NKTCL and defined three prominent subtypes, which differ significantly in cell of origin, EBV gene expression, transcriptional signatures, and responses to asparaginase-based regimens and targeted therapy. Our findings thus identify molecular networks of EBV-associated pathogenesis and suggest potential clinical strategies on NKTCL.

Unlabelled: B-cell lymphomas are highly aggressive forms of lymphoma that commonly present with lymphadenopathy, systemic "B" symptoms, or organ involvement making them easy to recognize; however, a small percentage of B-cell lymphomas can present without any typical symptoms or evidence of lymphadenopathy, resulting in delayed recognition and management. Isolated thrombocytopenia without anaemia or leukopenia is an unusual presentation of B cell lymphomas and may be misdiagnosed as immune thrombocytopenia (ITP). Given the rarity of this presentation, we wish to report a case of a 76-year-old female who presented with palpitations, shortness of breath, and recurrent chest infections.

Background: Invasive central nervous system (CNS) aspergillosis is rare among human immunodeficiency virus (HIV)-positive patients due to preserved neutrophil function, despite significant CD4+ T-cell depletion. Diagnosis typically requires histopathologic confirmation, but polymerase chain reaction (PCR) testing has introduced new challenges due to its high sensitivity but limited specificity.

Case Presentation: We describe a newly diagnosed 43-year-old HIV-positive male with concurrent Hodgkin lymphoma who presented with progressive neurological decline and a ring-enhancing brain lesion.

Integrative profiling of lung cancer biomarkers EGFR, ALK, KRAS, and PD-1 with emphasis on nanomaterials-assisted immunomodulation and targeted therapy.

Background: Lung cancer remains the leading cause of cancer-related mortality globally, primarily due to late-stage diagnosis, molecular heterogeneity, and therapy resistance. Key biomarkers such as EGFR, ALK, KRAS, and PD-1 have revolutionized precision oncology; however, comprehensive structural and clinical validation of these targets is crucial to enhance therapeutic efficacy.

Methods: Protein sequences for EGFR, ALK, KRAS, and PD-1 were retrieved from UniProt and modeled using SWISS-MODEL to generate high-confidence 3D structures.

Follicular dendritic cell sarcoma (FDCS) is a rare tumour derived from dendritic cells located in B-follicles that play a pivotal role in the adaptive immune response. Surgery is the mainstay of treatment for localized disease; however, the management of unresectable or advanced disease is less well-defined. To date, to the best of our knowledge, there is no established or preferred chemotherapeutic regimen, although a number of regimens (primarily used in lymphomas and sarcomas) have been utilized with suboptimal outcomes.

Introduction: We previously reported that sodium-glucose co-transporter 2 (SGLT-2) was ectopically overexpressed in adult T-cell leukemia (ATL) cells notably in aggressive type but in indolent type, and widely-used anti-diabetic SGLT-2 inhibitors (SGLT-2i) considerably attenuated proliferation of leukemic cells.

Methods: We performed retrospective analyses for 10 years to see whether SGLT-2i would prevent aggressive transformation in patients with indolent type ATL accompanied by diabetes. Nucleosome occupancy in the promotor region of the gene was also assessed to explore the possible involvement of epigenetic modification in such an ectopic overexpression.
