Metabolic tumor area (MTA) features simple operation and good reproducibility, holding potential as a practical alternative to TMTV. This retrospective study aimed to validate MTA's substitutability and explore its prognostic value in DLBCL risk stratification. A total of 295 newly diagnosed DLBCL patients were enrolled. TMTV and MTA were measured via semi-automatic segmentation (41% SUVmax threshold). Survival analysis, Cox regression, 5-fold cross-validation, and time-dependent ROC curves were used to evaluate prognostic performance. Multivariate analysis revealed MTA, rather than TMTV, independently predicted progression-free survival (PFS) and overall survival (OS) (all <i>p</i> &lt; 0.05), with stability confirmed by cross-validation.

This review argues that context-dependent chromatin states, not merely genetic lesions, determine disease trajectory, fibrotic transformation, and leukemic progression. We synthesize recent evidence indicating that PRC2 deficiency is supported by the strongest MPN-specific evidence for BRD4 dependency, whereas PARP/BCL-2 vulnerabilities associated with TET2/IDH mutations and USP7 dependency associated with ASXL1 remain supported primarily by related myeloid malignancies or preclinical studies. Introducing the concept of an “epigenetic clock” of clonal evolution, we propose that MPN cells acquire progressively pathological chromatin states that can be quantified through composite methylation and accessibility scores. Importantly, temporal synthetic lethality, using short epigenetic pulses to remodel chromatin before applying targeted agents, offers a rational scheduling strategy to expose non-redundant dependencies while sparing normal hematopoiesis. We outline a translational roadmap incorporating cfDNA methylome biomarkers, ongoing BET inhibitor trials, and emerging single-cell perturbation approaches. Finally, we highlight the “dark epigenome” of repetitive elements as an unexplored therapeutic frontier.

This scoping review was conducted to assess the current knowledge on the use of circulating tumor DNA (ctDNA), either alone or in combination with immune markers, as predictive tools for treatment outcome in previously untreated DLBCL patients. A systematic search of online databases PubMed, Embase, CINAHL, and Cochrane was performed from inception to May 2025. This focused on primary research studies investigating the use of ctDNA or immune markers to assess treatment response and predict outcomes in DLBCL. 61 publications were selected for inclusion. The key points of interest for this scoping review were: pre-analytical sample handling, laboratory methodologies—including sequencing panels and platforms; and mutations or immune markers associated with prognosis or patient outcome. Strong evidence supports the utility of ctDNA analysis at key timepoints to evaluate treatment response: diagnosis, cycle 2 day 1, cycle 3 day 1, and end of treatment. ctDNA assays with adequate sensitivity can improve interpretation of FDG<sup>18</sup>-PET/CT scans, reducing unnecessary additional testing for patients. Molecular clustering on ctDNA also improves risk stratification. Elevated cytokines such as CXCL10 and IL-10 and elevated numbers of myeloid derived suppressor cells in pre-treatment samples are associated with inferior prognosis. ctDNA analysis shows promise in improving outcomes for patients with DLBCL.

This review examines how the marrow niche changes across the MGUS–SMM–MM continuum. In early MGUS, the microenvironment may already be permissive, but it remains partly restrained: immune control is not fully lost, stromal activation is incomplete, vascular remodeling is limited, and the bone-remodeling compartment has not yet become overtly tumor-supportive. Progression appears to occur when these initially modest stromal, vascular, skeletal, immune, and extracellular matrix alterations become functionally connected. Once linked, these changes form reinforcing circuits that enhance plasma cell retention and survival, weaken immune containment, remodel the vascular and skeletal niche, and promote resistance to therapy. In this view, MGUS-to-MM progression is not simply a plasma cell–autonomous process, but a gradual ecological shift in which the marrow niche becomes increasingly aligned with the needs of the malignant clone. Understanding this coordinated microenvironmental remodeling may improve risk stratification and support therapeutic strategies that target both the plasma cell clone and its supportive niche.</p>\u0000 </div>","PeriodicalId":12882,"journal":{"name":"Hematological Oncology","volume":"44 5","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148758953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Defining a Therapeutic Window for Venetoclax in Post-Transplant Maintenance Therapy for High-Risk Acute Myeloid Leukemia and Myelodysplastic Syndromes","authors":"Cuicui Lyu,&nbsp;Tianle Xie,&nbsp;Yedi Pu,&nbsp;Xianshuang Luan,&nbsp;Xia Xiao,&nbsp;Mingfeng Zhao,&nbsp;Hairong Lyu","doi":"10.1002/hon.70237","DOIUrl":"10.1002/hon.70237","url":null,"abstract":"<p>Patients with high-risk acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) continue to face a substantial risk of relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT), which remains a leading cause of treatment failure. In our previous study, maintenance therapy with a combination of venetoclax and decitabine has shown potential in reducing relapse rates; however, its efficacy and safety, particularly in relation to drug concentration levels, are not yet fully elucidated. This study aimed to evaluate the influence of venetoclax blood concentrations on the efficacy and toxicity of venetoclax plus decitabine as maintenance therapy in high-risk AML/MDS patients after allo-HSCT. We retrospectively analyzed clinical data from 58 high-risk AML/MDS patients who received this maintenance regimen at our center between April 2018 and June 2023, with a focus on the association between venetoclax blood levels, treatment response, and adverse effects. The results demonstrated that the venetoclax–decitabine maintenance regimen was effective and generally well-tolerated, improving remission rates without significantly increasing intolerable toxicities or the risk of graft-versus-host disease (GVHD). Notably, substantial interindividual variability in venetoclax blood concentrations was observed. Patients with concentrations maintained within the range of 2605–4060 ng/mL achieved superior outcomes and higher safety profiles. In conclusion, this study provides key evidence for establishing a target concentration window for venetoclax, highlighting the importance of therapeutic drug monitoring in guiding post-transplant maintenance therapy for high-risk AML/MDS patients.</p>","PeriodicalId":12882,"journal":{"name":"Hematological Oncology","volume":"44 5","pages":""},"PeriodicalIF":4.1,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13446740/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148684225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
