Surgery/non-surgery-based strategies for invasive locally-advanced non-small cell lung cancer in the era of precision medicine.

Background: Treatments for invasive T non-small cell lung cancer (NSCLC) tumors have been traditionally individualized and often require multidisciplinary team (MDT) evaluation. Advances in precision medicine may open up new opportunities for these patients.

Methods: This retrospective cohort study, using the Surveillance, Epidemiology, and End Results (SEER) database, identified TNM NSCLC patients with central structure invasion from 2010 to 2020.

The C5a/C5aR1 axis promotes migration of tolerogenic dendritic cells to lymph nodes, impairing the anticancer immune response.

The precise mechanisms by which the complement system contributes to the establishment of an immunosuppressive tumor microenvironment (TME) and promotes tumor progression remain unclear. In this study, we investigated the expression and function of complement C5a receptor 1 (C5aR1) in human and mouse cancer-associated dendritic cells (DCs). First, we observed an overexpression of C5aR1 in tumor-infiltrating DCs, compared to DCs from blood or spleen.

Machine Learning-based Prognostic Subgrouping of Glioblastoma: A Multi-center Study.

Background: Glioblastoma is the most aggressive adult primary brain cancer, characterized by significant heterogeneity, posing challenges for patient management, treatment planning, and clinical trial stratification.

Methods: We developed a highly reproducible, personalized prognostication and clinical subgrouping system using machine learning (ML) on routine clinical data, MRI, and molecular measures from 2,838 demographically diverse patients across 22 institutions and 3 continents. Patients were stratified into favorable, intermediate, and poor prognostic subgroups (I, II, III) using Kaplan-Meier analysis (Cox proportional model and hazard ratios [HR]).

Characterization of tumor microenvironment and cell interaction patterns in testicular and diffuse large B-cell lymphomas.

The tumor microenvironments (TME) of diffuse large B-cell lymphoma (DLBCL) subgroups have remained poorly characterized. Here, we dissected the composition and spatial organization of the TME in germinal center B-cell (GCB), activated B-cell (ABC), and testicular DLBCLs (T-DLBCL) using gene expression profiling and multiplex immunohistochemistry. We found that high proportions of M2-like tumor-associated macrophages (TAMs) and cytotoxic tumor-infiltrating T cells (TILs) were characteristic of ABC DLBCL TME.

Development of a fibrin-targeted theranostic for gastric cancer.

Patients with advanced gastric cancer (GCa) have limited treatment options, and alternative treatment approaches are necessary to improve their clinical outcomes. Because fibrin is abundant in gastric tumors but not in healthy tissues, we hypothesized that fibrin could be used as a high-concentration depot for a high-energy beta-emitting cytotoxic radiopharmaceutical delivered to tumor cells. We showed that fibrin is present in 64 to 75% of primary gastric tumors and 50 to 100% of metastatic gastric adenocarcinoma cores.

Exploring aggregation genes in a chronic infection model.

Unlabelled: Bacterial aggregates are observed in both natural and artificial environments. In the context of disease, aggregates have been isolated from chronic and acute infections. () aggregates contribute significantly to chronic infections, particularly in the lungs of people with cystic fibrosis (CF).

Imlunestrant with or without Abemaciclib in Advanced Breast Cancer.

Background: Imlunestrant is a next-generation, brain-penetrant, oral selective estrogen-receptor (ER) degrader that delivers continuous ER inhibition, even in cancers with mutations in the gene encoding ERα ().

Methods: In a phase 3, open-label trial, we enrolled patients with ER-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer that recurred or progressed during or after aromatase inhibitor therapy, administered alone or with a cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitor. Patients were assigned in a 1:1:1 ratio to receive imlunestrant, standard endocrine monotherapy, or imlunestrant-abemaciclib.

Fluorinated polyethyleneimine vectors with serum resistance and adjuvant effect to deliver LMP2 mRNA vaccine for nasopharyngeal carcinoma therapy.

Latent membrane protein 2 (LMP2), which is an important protein of Epstein-Barr virus (EBV) in the latent phase to mediate metastasis and recurrence, has shown great potential as a targeting antigen in mRNA vaccine for nasopharyngeal carcinoma (NPC) therapy. In this study, an LMP2 mRNA vaccine was developed based on a serum-resistant fluorinated polyethyleneimine (PF) with the self-adjuvant effect for achieving a strong anti-tumor immunity in NPC treatment. Specifically, the proposed vaccine PEG[PF/mLMP2] was comprised of a PF/mLMP2 core formed by the cationic PF and LMP2 mRNA, together with a dialdehyde poly (ethyl glycol) (OHC-PEG-CHO) coating.

Integrated Single-Cell and Spatial Transcriptome Reveal Metabolic Gene SLC16A3 as a Key Regulator of Immune Suppression in Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is one of the most lethal cancers, usually diagnosed at an advanced stage. Metabolic reprogramming plays a significant role in HCC progression, probably related to immune evasion, yet the key gene is unclear. In this study, six metabolism-related genes with prognostic implications were screened.

Tumor burden quantified by Soluble B-Cell Maturation Antigen and Metabolic Tumor Volume determine myeloma CAR-T outcomes.

Chimeric antigen receptor T-cell (CAR-T) therapy has emerged as a breakthrough treatment for relapsed and refractory multiple myeloma (RRMM). However, these products are complex to deliver and alternative options are now available. Identifying biomarkers that can predict therapeutic outcomes is crucial for optimizing patient selection.

Blinatumomab in Standard-Risk B-Cell Acute Lymphoblastic Leukemia in Children.

Background: B-cell acute lymphoblastic leukemia (B-cell ALL) is the most common childhood cancer. Despite a high overall cure rate, relapsed B-cell ALL remains a leading cause of cancer-related death among children. The addition of the bispecific T-cell engager molecule blinatumomab (an anti-CD19 and anti-CD3 single-chain molecule) to therapy for newly diagnosed standard-risk (as defined by the National Cancer Institute) B-cell ALL in children may improve outcomes.

Conjugation of Antibodies and siRNA Duplexes to Polymer Nanoparticles via Maleimide-Thiol Chemistry.

Polymeric nanoparticles (NPs) have shown great promise as highly modifiable platforms that can be applied across many different disease states. They are advantageous because they can encapsulate a range of hydrophobic and hydrophilic cargoes while having customizable surface properties. Depending on the desired biointerfacing capabilities, the surface of polymeric NPs can be modified with moieties, such as antibodies, peptides, nucleic acids, and more.

Identifying targeted cell-free DNA methylation regions in head and neck cancer via paired methylome analysis.

Despite the critical need, progress in developing cell-free DNA (cfDNA) liquid biopsy biomarkers for the diagnosis and risk stratification of head and neck squamous cell carcinoma (HNSC) has been limited. In this study, we present a comprehensive paired-sample differential methylation region (psDMR) analysis in HNSC, aimed at identifying reliable and HNSC-specific regions for cfDNA biomarker discovery. Traditional DMR analyses often overlook paired-sample information and fail to account for the heterogeneity within HNSC tissues.

Viral Load Measurements for Kaposi Sarcoma Herpesvirus (KSHV/HHV8): Review and an Updated Assay.

"When you can measure what you are speaking about, and express it in numbers, you know something about it." is a famous quote attributed to Lord Kelvin. This sentiment puts viral load measurements at the center of virology.

Discovery of a novel Fam20C inhibitor for treatment of triple-negative breast cancer.

Sequence similarity 20 family member C (Fam20C), a Golgi casein kinase, has a gradually elucidated mechanism in triple-negative breast cancer (TNBC) and is considered a possible target for therapeutic intervention. In this study, we combined virtual screening and chemical synthesis methods to obtain a new small-molecule Fam20C inhibitor, compound 5k, which possesses desirable kinase inhibitory activity against Fam20C and significant anti-proliferative activity against MDA-MB-231 and BT-549 cells. Subsequently, cellular thermal shift assay (CETSA), molecular docking, and molecular dynamics (MD) simulations revealed that compound 5k binds to Fam20C.

A computational approach to matching multiple sclerosis-related, IGH CDR3s with a MBP epitope.

In multiple sclerosis (MS), T-cell receptors (TCRs) and antibodies specifically target the main structural proteins of myelin, including myelin basic protein (MBP), especially a specific, canonical, immunoglobulin (IG)-targeted MBP epitope. Efficient computational analyses to diagnose or monitor autoimmune conditions, which could have broad applicability in clinical trials or in diagnoses, remains a challenge. As such, we considered the possibility that focusing on the immunoglobin heavy chain (IGH) complementarity determining region-3 (CDR3) amino acid sequences could support the development of an efficient, convenient, and user-friendly approach to detecting or assessing IGH targets in MS.

Perioperative Bone Mineral Density Assessment in Patients With Primary Hyperparathyroidism.

Introduction: Primary hyperparathyroidism (PHPT) increases the risk of osteoporosis and fractures. Despite American Association of Endocrine Surgeons guidelines that recommend bone mineral density (BMD) assessment via dual-energy x-ray absorptiometry (DEXA) for PHPT patients, adherence to these guidelines remains suboptimal.

Methods: We performed a retrospective review of preoperative and postoperative DEXA scan practices among PHPT patients at a single academic medical center between 2000 and 2018.

Symptom Monitoring App Use Associated With Medication Adherence Among Woman Survivors of Breast Cancer on Adjuvant Endocrine Therapy.

Purpose: Oral adjuvant endocrine therapy (AET) reduces the risk of cancer recurrence and death for women with hormone receptor-positive (HR+) breast cancer. Because of adverse symptoms and socioecologic barriers, AET adherence rates are low. We conducted post hoc analyses of a randomized trial of a remote symptom and adherence monitoring app to evaluate characteristics associated with higher app use, satisfaction, and how app use was associated with AET adherence.
