Smoking carcinogen induced inflammation promotes lung carcinogenesis via IRAK4 activation.

Purpose: Even though smoking is associated with lung cancer, the exact molecular pathways that link carcinogens with inflammation and oncogenic transformation are not well elucidated. Two major carcinogens in cigarette smoke, Nicotine-derived nitrosamine ketone, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and benzo(α)pyrene (BaP) have not been tested in models that mimic inhaled exposure for prolonged periods of time.

Experimental Design: ICR mice were treated with intratracheal delivery of NNK and BaP (NB) for 18 months.

Lung Cancer with Brain Metastasis-Treatment Strategies and Molecular Characteristics.

Lung cancer is a leading cause of brain metastases (BMs), with 10-20% of patients with non-small cell lung cancer (NSCLC) presenting with BMs at diagnosis and 25-50% developing them over the course of their disease. Historically, BMs have posed significant therapeutic challenges, partly due to the blood brain barrier (BBB), which restricts drug penetration to the central nervous system. Consequently, BMs were initially managed with local treatments, including surgical resection, stereotactic radiosurgery, and whole brain radiation therapy.

Aurora Kinase A Inhibition Potentiates Platinum and Radiation Cytotoxicity in Non-Small-Cell Lung Cancer Cells and Induces Expression of Alternative Immune Checkpoints.

Despite major advances in non-small-cell lung cancer (NSCLC) treatment, the five-year survival rates for patients with non-oncogene-driven tumors remain low, necessitating combinatory approaches to improve outcomes. Our prior high-throughput RNAi screening identified Aurora kinase A (AURKA) as a potential key player in cisplatin resistance. In this study, we investigated AURKA's role in platinum and radiation sensitivity in multiple NSCLC cell lines and xenograft mouse models, as well as its effect on immune checkpoints, including PD-L1, B7x, B7-H3, and HHLA2.

Lung-MAP Next-Generation Sequencing Analysis of Advanced Squamous Cell Lung Cancers (SWOG S1400).

Introduction: Squamous cell cancer (SqCC) is a lung cancer subtype with few targeted therapy options. Molecular characterization, that is, by next-generation sequencing (NGS), is needed to identify potential targets. Lung Cancer Master Protocol Southwest Oncology Group S1400 enrolled patients with previously treated stage IV or recurrent SqCC to assess NGS biomarkers for therapeutic sub-studies.

Impact of Shenmai Injection Combined with Chemotherapy on T-cell Subsets and Cytokine Profiles in Patients with Advanced Non-Small Cell Lung Cancer.

Background: Non-small cell lung cancer (NSCLC) represents a significant portion of lung cancer cases, with a poor prognosis and limited treatment options for advanced stages. Enhancing the effectiveness of chemotherapy through adjunctive therapies is a critical area of research.

Objective: To evaluate the effect of Shenmai injection combined with chemotherapy on T-cell subsets and cytokine expression in patients with advanced NSCLC.

A novel copy number variant in the murine Cdh23 gene gives rise to profound deafness and vestibular dysfunction.

Hearing loss is the most common congenital sensory deficit worldwide and exhibits high genetic heterogeneity, making molecular diagnoses elusive for most individuals. Detecting novel mutations that contribute to hearing loss is crucial to providing accurate personalized diagnoses, tailored interventions, and improving prognosis. Copy number variants (CNVs) are structural mutations that are understudied, potential contributors to hearing loss.

Detection of PD‑L1 expression and epithelial‑mesenchymal transition of circulating tumor cells in non‑small cell lung cancer.

The present study aimed to assess the roles of peripheral circulating tumor cell (CTC) count, CTC subtypes and programmed death ligand 1 (PD-L1) expression in the clinical staging and prognosis of patients with non-small cell lung cancer (NSCLC). A total of 100 patients with NSCLC with available tumor tissues were enrolled in the present study, and 7.5 ml peripheral blood was collected.

Two missense gene variations impaired LKB1/adenosine monophosphate-activated protein kinase signaling in Peutz-Jeghers syndrome.

Background: Peutz-Jeghers syndrome (PJS) is a rare hereditary neoplastic disorder mainly associated with serine/threonine kinase 11 (/) gene mutations. Preimplantation genetic testing can protect a patient's offspring from mutated genes; however, some variations in this gene have been interpreted as variants of uncertain significance (VUS), which complicate reproductive decision-making in genetic counseling.

Aim: To identify the pathogenicity of two missense variants and provide clinical guidance.

Longitudinal Magnetic Resonance Imaging Tracking of Transplanted Neural Progenitor Cells in the Spinal Cord Utilizing the Bright-Ferritin Mechanism.

Human neural progenitor cells (hNPCs) hold promise for treating spinal cord injury. Studies to date have focused on improving their regenerative potential and therapeutic effect. Equally important is ensuring successful delivery and engraftment of hNPCs at the injury site.

Consolidation Osimertinib Versus Durvalumab Versus Observation After Concurrent Chemoradiation in Unresectable EGFR-Mutant NSCLC: A Multicenter Retrospective Cohort Study.

Introduction: Durvalumab improves survival when used as consolidation therapy after chemoradiation (CRT) in patients with stage III NSCLC. The optimal consolidation therapy for patients with EGFR-mutant (EGFRmut) stage III NSCLC remains unknown.

Methods: In this multi-institutional, international retrospective analysis across 24 institutions, we evaluated outcomes in patients with stage III EGFRmut NSCLC treated with concurrent CRT followed by consolidation therapy with osimertinib, durvalumab, or observation between 2015 and 2022.

HIV Associated Lung Cancer: Unique Clinicopathologic Features and Immune Biomarkers Impacting Lung Cancer Screening and Management.

Objectives: Lung cancer contributes significantly to morbidity and mortality in people with HIV (PWH). We study the clinicopathologic characteristics and immune microenvironment in HIV associated lung cancer.

Material And Methods: Clinicopathological characteristics including immunotherapy outcomes were collected for 174 PWH diagnosed with lung cancer.

Similar Efficacy Observed for First-Line Immunotherapy in Racial/Ethnic Minority Patients With Metastatic NSCLC.

Background: Limited data exist on the impact of immunotherapy use in ethnic minority patients with non-small cell lung cancer (NSCLC), because they have been underrepresented in immunotherapy trials. This study aims to evaluate race/ethnicity and other demographic, socioeconomic, and clinical factors of patients with metastatic NSCLC treated with first-line immunotherapy.

Methods: A retrospective cohort study of 5,920 patients diagnosed with lung cancer treated at Montefiore Einstein Cancer Center from January 1, 2013, to June 1, 2022, was used to identify patients with metastatic NSCLC without EGFR, ALK, or ROS1 alterations who underwent first-line immunotherapy (n=248).

Selective Personalized RadioImmunotherapy for Locally Advanced Non-Small-Cell Lung Cancer Trial (SPRINT).

Purpose: Standard therapy for locally advanced non-small-cell lung cancer (LA-NSCLC) is concurrent chemoradiotherapy followed by adjuvant durvalumab. For biomarker-selected patients with LA-NSCLC, we hypothesized that sequential pembrolizumab and risk-adapted radiotherapy, without chemotherapy, would be well-tolerated and effective.

Methods: Patients with stage III NSCLC or unresectable stage II NSCLC and an Eastern Cooperative Oncology Group performance status of 0-1 were eligible for this trial.

To date, limited studies have reported DEEs driven by FGF13. Here, we reported a girl with developmental and epileptic encephalopathy 90 caused by variant of FGF13.

Temporal genomic heterogeneity guiding individualized therapy in recurrent non-small cell lung cancer.

Introduction: Despite the benefit of adjuvant systemic therapy for patients with resected non-small cell lung cancer (NSCLC), the risk of postoperative recurrence remains high. Our objective was to characterize temporal genetic heterogeneity between primary resected and recurrent tumors, and its impact on treatment outcomes.

Methods: In this study, next-generation sequencing (NGS) testing was performed on tissue specimens and circulating tumor DNA (ctDNA) collected at postoperative recurrence, and results were compared to the genotypes of initial surgical specimens.
