Article Abstract
Background: Lung cancer has the highest mortality rate among cancers worldwide, and most patients are diagnosed with non-small-cell lung cancer (NSCLC), and evaluating the clinical efficacy of molecularly targeted cancer therapy remains a major challenge.
Methods: This paper retrospectively investigated the outcome information of 291 lung cancer patients detected by next-generation sequencing (NGS) analysis and fluorescence in situ hybridization (FISH), including 63 patients with lung cancer who were followed up. We analyzed epidermal growth factor receptor (EGFR) mutation abundance and aneuploidy status to evaluate clinical efficacy.
Results: The progress free survival (PFS) of patients diagnosed as euploidy was actually higher than that of patients diagnosed with aneuploidy, and was related to both the objective response rate (ORR) and disease control rate (DCR). Patients with an epidermal growth factor receptor (EGFR) mutation abundance ≥28.86% had slightly higher ORR and similar DCR. Two-way analysis of variance was used to assess the effects of EGFR mutation abundance and tumor aneuploidy status on patients' PFS. The results indicated a strong correlation between aneuploidy status and clinical efficacy, with euploid patients having a higher ORR and DCR.
Conclusions: Aneuploidy status could effectively evaluate the clinical efficacy of patients with lung cancer. However, EGFR mutations abundance could not predict the extent of benefit from tyrosine kinase inhibitors (EGFR-TKI) treatment.

Mechanistic insights into MET exon 14 skipping mutations and their role in tumor progression.

The MET receptor tyrosine kinase is a pivotal regulator of cellular survival, motility, and proliferation. Mutations leading to skipping of exon 14 (METΔex14) within the juxtamembrane domain of MET impair receptor degradation and prolong oncogenic signaling, contributing significantly to tumor progression across multiple cancer types. METΔex14 mutations are associated with aggressive clinical behavior, therapeutic resistance, and poor outcomes.

MicroRNAs (miRNAs) are critical regulators of gene expression in cancer biology, yet their spatial dynamics within tumor microenvironments (TMEs) remain underexplored due to technical limitations in current spatial transcriptomics (ST) technologies. To address this gap, we present STmiR, a novel XGBoost-based framework for spatially resolved miRNA activity prediction. STmiR integrates bulk RNA-seq data (TCGA and CCLE) with spatial transcriptomics profiles to model nonlinear miRNA-mRNA interactions, achieving high predictive accuracy (Spearman's ρ > 0.

Heart failure (HF) and lung cancer (LC) often coexist, yet their shared molecular mechanisms are unclear. We analyzed transcriptome data from the NCBI Gene Expression Omnibus (GEO) database (GSE141910, GSE57338) to identify 346 HF‑related differentially expressed genes (DEGs), then combined weighted gene co-expression network analysis (WGCNA) pinpointed 70 hub candidates. Further screening of these 70 hub candidates in TCGA lung cancer cohorts via LASSO, Random Forest, and multivariate Cox regression suggested CYP4B1 as the only independent prognostic marker.

Volumetric modulated arc therapy (VMAT) for lung cancer involves complex multileaf collimator (MLC) motion, which increases sensitivity to interplay effects with tumour motion. Current dynamic conformal arc methods address this issue but may limit the achievable dose distribution optimisation compared with standard VMAT. This study examined the clinical utility of a VMAT technique with monitor unit limits (VMATliMU) to mimic conformal arc delivery and reduce interplay effects while maintaining plan quality.

Importance: Patients with advanced cancer frequently receive broad-spectrum antibiotics, but changing use patterns across the end-of-life trajectory remain poorly understood.
Objective: To describe the patterns of broad-spectrum antibiotic use across defined end-of-life intervals in patients with advanced cancer.
Design, Setting, And Participants: This nationwide, population-based, retrospective cohort study used data from the South Korean National Health Insurance Service database to examine broad-spectrum antibiotic use among patients with advanced cancer who died between July 1, 2002, and December 31, 2021.
