Histomorphologic spectrum of nodal marginal zone lymphoma as defined by its methylome.

Objectives: Primary nodal marginal B-cell lymphoma (NMZL) is rare and histologically very variable. Its large-cell presentation is difficult to distinguish from nodal diffuse large B-cell lymphoma (nDLBCL) due to the absence of specific markers for nodal marginal zone lymphomas in general.

Methods: Using a comprehensive cohort of NMZLs and a control cohort of nDLBCLs, we conducted a methylome analysis on subgroups of both.

When Metal Complexes Evolve, and a Minor Species is the Most Active: the Case of Bis(Phenanthroline)Copper in the Catalysis of Glutathione Oxidation and Hydroxyl Radical Generation.

Several copper-ligands, including 1,10-phenanthroline (Phen), have been investigated for anticancer purposes based on their capacity to bind excess copper (Cu) in cancer tissues and form redox active complexes able to catalyse the formation of reactive oxygen species (ROS), ultimately leading to oxidative stress and cell death. Glutathione (GSH) is a critical compound as it is highly concentrated intracellularly and can reduce and dissociate copper(II) from the ligand forming poorly redox-active copper(I)-thiolate clusters. Here we report that Cu-Phen speciation evolves in physiologically relevant GSH concentrations.

Differential lipid signaling from CD4 and CD8 T cells contributes to type 1 diabetes development.

Introduction: We reported that Ca-independent phospholipase Aβ (iPLAβ)-derived lipids (iDLs) contribute to type 1 diabetes (T1D) onset. As CD4 and CD8 T cells are critical in promoting β-cell death, we tested the hypothesis that iDL signaling from these cells participates in T1D development.

Methods: CD4 and CD8 T cells from wild-type non-obese diabetic () and .

Translating efficacy of liver transplantation in liver-limited metastatic colorectal cancer into clinical practice: the TransMet trial.

Pioneer studies suggested that liver transplantation (LT) has the potential to provide long-term survival in patients with liver-limited metastatic colorectal cancer (mCRC) not amenable for surgery of metastases. Evidence, however, was limited to single-arm studies with few patients enrolled and suboptimal selection criteria, with concerns over access to organ availability overcoming the potential efficacy of LT in this setting. Recently, 5-year survival rates with chemotherapy followed by LT (73%) compared with chemotherapy alone (9%) have been demonstrated by the randomized TransMet trial, enrolling 94 definitively unresectable strictly selected liver-limited mCRC patients.

Large B-cell lymphomas with CCND1 rearrangement have different immunoglobulin gene breakpoints and genomic profile than mantle cell lymphoma.

Mantle cell lymphoma (MCL) is genetically characterized by the IG::CCND1 translocation mediated by an aberrant V(D)J rearrangement. CCND1 translocations and overexpression have been identified in occasional aggressive B-cell lymphomas with unusual features for MCL. The mechanism generating CCND1 rearrangements in these tumors and their genomic profile are not known.

Overall Survival with Pembrolizumab in Early-Stage Triple-Negative Breast Cancer.

Background: In patients with early-stage triple-negative breast cancer, the phase 3 KEYNOTE-522 trial showed significant improvements in pathological complete response and event-free survival with the addition of pembrolizumab to platinum-containing chemotherapy. Here we report the final results for overall survival.

Methods: We randomly assigned, in a 2:1 ratio, patients with previously untreated stage II or III triple-negative breast cancer to receive neoadjuvant therapy with four cycles of pembrolizumab (at a dose of 200 mg) or placebo every 3 weeks plus paclitaxel and carboplatin, followed by four cycles of pembrolizumab or placebo plus doxorubicin-cyclophosphamide or epirubicin-cyclophosphamide.

Preoperative Chemoradiotherapy for Resectable Gastric Cancer.

Background: In Western countries, the current standard of care for resectable gastric cancer is perioperative chemotherapy. Preoperative chemoradiotherapy has been considered, but data are limited regarding this treatment as compared with perioperative chemotherapy alone.

Methods: We conducted an international, phase 3 trial in which patients with resectable adenocarcinoma of the stomach or gastroesophageal junction were randomly assigned to receive preoperative chemoradiotherapy plus perioperative chemotherapy or perioperative chemotherapy alone (control).

Long-Term Follow-Up of the Prospective Randomized AATT Study (Autologous or Allogeneic Transplantation in Patients With Peripheral T-Cell Lymphoma).

JCO Primary analysis of the phase III randomized AATT study showed that younger patients with peripheral T-cell lymphoma (PTCL) consolidated with autologous or allogeneic transplantation (alloSCT) had similar event-free survival (EFS) and overall survival (OS). Seven-year EFS of patients randomly assigned to alloSCT was 38% (95% CI, 25 to 52) compared with 34% (95% CI, 22 to 47) for patients randomly assigned to autologous transplantation of hematopoietic stem cells (autoSCT); OS was 55% (95% CI, 41 to 69) and 61% (95% CI, 47 to 74). Among patients undergoing alloSCT (n = 26) or autoSCT (n = 41) on study, the cumulative progression/relapse rate was 8% (95% CI, 0 to 19) and 55% (95% CI, 35 to 74).

Cryotherapy versus radical prostatectomy as a salvage treatment for radio-recurrent prostate cancer.

Introduction: The aim of this study is to compare outcomes of SRP (salvage radical prostatectomy) with SCAP (salvage cryoablation of the prostate) in local radio-recurrent PCa (prostate cancer) patients.

Materials And Methods: A retrospective analysis of a multicentric European Society of Uro-technology (ESUT) database was performed. Data on patients with local recurrent PCa after radiotherapy who underwent salvage treatment were collected.

Simultaneous multicolor fluorescence imaging using PSF splitting.

We present a way to encode more information in fluorescence imaging by splitting the original point spread function (PSF), which offers broadband operation and compatibility with other PSF engineering modalities and existing analysis tools. We demonstrate the approach using the 'Circulator', an add-on that encodes the fluorophore emission band into the PSF, enabling simultaneous multicolor super-resolution and single-molecule microscopy using essentially the full field of view.

A pooled analysis of trastuzumab deruxtecan in patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer with brain metastases.

Background: This exploratory pooled analysis investigated the efficacy and safety of trastuzumab deruxtecan (T-DXd) versus comparator treatment in patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (mBC) with brain metastases (BMs) at baseline, categorized according to previous local treatment.

Patients And Methods: T-DXd data were pooled from DESTINY-Breast01/-02/-03. Comparator data, from patients receiving physician's choice therapy and trastuzumab emtansine, were pooled from DESTINY-Breast02 and -03, respectively.

Diabetes risk reduction diet and risk of liver cancer and chronic liver disease mortality: A prospective cohort study.

Background: We aimed to prospectively evaluate the association between a diabetes risk reduction diet (DRRD) score and the risk of liver cancer development and chronic liver disease-specific mortality.

Methods: We included 98,786 postmenopausal women from the Women's Health Initiative-Observational Study and the usual diet arm of the Diet Modification trial. The DRRD score was derived from eight factors: high intakes of dietary fiber, coffee, nuts, polyunsaturated fatty acids, low intakes of red and processed meat, foods with high glycemic index, sugar-sweetened beverages (SSBs), and trans fat based on a validated Food-Frequency Questionnaire administered at baseline (1993-1998).

Heparin-like effect of a dual antiplatelet and anticoagulant (APAC) agent on red blood cell deformability and aggregation in an experimental model.

Treatments with different antithrombotic agents can affect micro-rheological variables, such as red blood cell (RBC) deformability and aggregation. Since the effect of dual antiplatelet and anticoagulant (APAC) treatment on micro-rheology is unknown, we aimed to investigate the effect of different intravenous doses of APAC on hematological and micro-rheological variables in a porcine model. Two groups were formed (APAC group, Control group), and blood was collected from the animals at preset intervals.

The life threat in hematopoietic allogeneic stem cell transplantation - an interview and focus group study on health care professionals' perspectives.

Understanding healthcare professionals' (HCPs) experiences with patients undergoing hematopoietic allogeneic stem cell transplantation (allo-HSCT) is crucial, given its dual nature of offering a hope for cure which on the other hand is accompanied by a high risk for morbidity and mortality. Yet, how HCPs experience their patients' existential threats remains unexplored. Qualitative thematic content analysis was employed to comprehend these experiences.

Metabolite Predictors of Breast and Colorectal Cancer Risk in the Women's Health Initiative.

Metabolomics has been used extensively to capture the exposome. We investigated whether prospectively measured metabolites provided predictive power beyond well-established risk factors among 758 women with adjudicated cancers [ = 577 breast (BC) and = 181 colorectal (CRC)] and = 758 controls with available specimens (collected mean 7.2 years prior to diagnosis) in the Women's Health Initiative Bone Mineral Density subcohort.

Aberrant p53 immunostaining patterns in breast carcinoma of no special type strongly correlate with presence and type of TP53 mutations.

Recent studies have revealed an association between TP53 mutations and endocrine resistance in hormone receptor-positive, HER2-negative breast cancer (HR + HER2 -BC). Aberrant p53 immunostaining (IHC) patterns may provide a surrogate marker for TP53 mutations. Building upon a ternary algorithm of aberrant staining patterns, this study evaluates the reliability of p53 IHC as screening tool for TP53 mutations in BC (NST).
