Front-line liquid biopsy for early molecular assessment and treatment of hospitalized lung cancer patients.

Background: Molecular characterization is pivotal for managing non-small cell lung cancer (NSCLC), although this process is often time-consuming and patients' conditions might worsen while molecular analyses are processed. Our primary aim was to evaluate the performance of "up-front" next-generation sequencing (NGS) through liquid biopsy (LB) of hospitalized patients with newly detected lung neoplasm in parallel with conventional diagnosis. The secondary aim included longitudinal monitoring through LB of patients with oncogenic alterations at baseline.

Extracellular vesicles miR-574-5p and miR-181a-5p as prognostic markers in NSCLC patients treated with nivolumab.

Immune checkpoint inhibitors (ICIs) have revolutionized the management of advanced non-small cell lung cancer (NSCLC), although patient survival is still unsatisfactory. Accurate predictive markers capable of personalizing the treatment of patients with NSCLC are still lacking. Circulating extracellular vesicles involved in cell-to-cell communications through miRNAs (EV-miRs) transfer are promising markers.

Circulating Osteopontin Predicts Clinical and Radiological Response in First-Line Treatment of Advanced Non-Small Cell Lung Cancer.

Purpose: Pembrolizumab-based regimens are conditioned by the expression of PD-L1, but durable response rate is limited by innate and acquired resistance mechanisms. Here, we focus on osteopontin (OPN), an upfront biomarker of senescence, which closely associated with natural history of non-small cell lung cancer (NSCLC).

Methods: Seventy-nine patients eligible to pembrolizumab regimens-alone or in combination with chemotherapy-as first-line treatment of advanced NSCLC were enrolled.

Molecular and Genetic Advances in Small Cell Lung Cancer Landscape: From Homogeneity to Diversity.

Small cell lung cancer (SCLC) has been historically considered a homogeneous disease and thus approached as a single entity when it comes to clinical studies design and new treatments developments. However, increasing knowledge in the genetic and molecular landscape of this disease challenges this concept, opening the possibility that different subtypes might show differential vulnerability to treatments. In this narrative review, we gather the most relevant advances in genetic and molecular characterization of SCLC, focusing on how these discoveries may be used to design the path for a personalized treatment approach.

Diagnosis of lung cancer following emergency admission: Examining care pathways, clinical outcomes, and advanced NSCLC treatment in an Italian cancer Center.

Background: Lung cancer patients diagnosed following emergency admission often present with advanced disease and poor performance status, leading to suboptimal treatment options and outcomes. This study aimed to investigate the clinical and molecular characteristics, treatment initiation, and survival outcomes of these patients.

Methods: We retrospectively analyzed data from 124 patients diagnosed with lung cancer following emergency admission at a single institution.

Prognostic Role of Soluble and Extracellular Vesicle-Associated PD-L1, B7-H3 and B7-H4 in Non-Small Cell Lung Cancer Patients Treated with Immune Checkpoint Inhibitors.

The treatment of non-small cell lung cancer (NSCLC) has changed dramatically with the advent of immune checkpoint inhibitors (ICIs). Despite encouraging results, their efficacy remains limited to a subgroup of patients. Circulating immune checkpoints in soluble (s) form and associated with extracellular vesicles (EVs) represent promising markers, especially in ICI-based therapeutic settings.

Immune Checkpoint Blockade: A Strategy to Unleash the Potential of Natural Killer Cells in the Anti-Cancer Therapy.

Immunotherapy-chemotherapy combinations for non-small cell lung cancer: current trends and future perspectives.

Introduction: In recent years, immunotherapy has become a pillar in the treatment of advanced, non-oncogene-addicted non-small cell lung cancer (NSCLC). Programmed death ligand 1 (PD-L1) expression is currently the only factor used to predict response to immunotherapy in clinical practice. Specifically, single-agent pembrolizumab as first-line therapy is approved for tumors with high expression of PD-L1 (≥50%) while immunotherapy and chemotherapy are approved for any PD-L1.

The impact of COVID-19 on consumption poverty in Mozambique.

This study assesses the impact of COVID-19 on household consumption poverty. To predict changes in income and the associated effects on poverty, we rely on existing estimated macroeconomic impacts. We assume two main impact channels: direct income/wage and employment losses.

Novel approaches for the treatment of unresectable malignant pleural mesothelioma: A focus on immunotherapy and target therapy (Review).

Malignant pleural mesothelioma (MPM) is considered a relatively uncommon disease but its incidence is increasing worldwide. Patients affected by MPM have a very severe prognosis and have been often occupationally and environmentally exposed to asbestos. In recent years, checkpoint inhibitors have dramatically revolutionized the paradigm for the treatment of several malignancies.

Radiation-Related Deregulation of TUBB3 and BRCA1/2 and Risk of Secondary Lung Cancer in Women With Breast Cancer.

Introduction: Breast cancer survivors are at increased risk of developing unrelated primary cancers, particularly lung cancer. Evidence indicates that sex hormones as well as a deregulation of DNA-repair pathways may contribute to lung cancer onset. We investigated whether the hormone status and expression of markers involved in DNA repair (BRCA1/2, ERCC1, and P53R2), synthesis (TS and RRM1), and cell division (TUBB3) might be linked to lung cancer risk.

Correlation between B7-H4 and Survival of Non-Small-Cell Lung Cancer Patients Treated with Nivolumab.

Reliable predictors of benefit from immune checkpoint inhibitors in non-small-cell lung cancer (NSCLC) are still limited. We aimed to evaluate the association between the expression of selected molecules involved in immune response and clinical outcomes in NSCLC patients receiving nivolumab. In our study, the outcomes of 46 NSCLC patients treated with nivolumab in second or subsequent lines (Nivolumab Cohort) were compared with the expression of PD-L1, PD-L2, PD-1, B7-H3, and B7-H4 assessed by immunohistochemistry (IHC).

Integrated Somatic and Germline Whole-Exome Sequencing Analysis in Women with Lung Cancer after a Previous Breast Cancer.

Women treated for breast cancer (BC) are at risk of developing secondary tumors, such as lung cancer (LC). Since rare germline variants have been linked to multiple cancer development, we hypothesized that BC survivors might be prone to develop LC as a result of harboring rare variants. Sixty patients with LC with previous BC (the study population; SP) and 53 women with either BC or LC and no secondary cancer (control population; CP) were enrolled.

CIMAvax-EGF, a therapeutic non-small cell lung cancer vaccine.

Lung cancer represents the most common cause of cancer death worldwide. While the prognosis remains poor, immunotherapy is giving a positive impact on survival. Cancer vaccines represent a form of active immunotherapy that historically has given modest results in terms of efficacy.

Serial Troponin for Early Detection of Nivolumab Cardiotoxicity in Advanced Non-Small Cell Lung Cancer Patients.

Background: Rare cases of severe myocarditis are reported during treatment with nivolumab. Troponin, a biomarker of cardiac damage, is a key component of the diagnostic workup of many cardiac disorders, including myocarditis. This study investigates the role of troponin to assess cardiac involvement during nivolumab therapy for non-small cell lung cancer (NSCLC).

Prognostic role of the VeriStrat test in first line patients with non-small cell lung cancer treated with platinum-based chemotherapy.

Objectives: VeriStrat is a blood-based test that utilizes matrix-assisted laser desorption/ionization time-of-flight (MALDI ToF) mass spectrometry to assign a binary classification of VeriStrat Good or VeriStrat Poor that is associated with treatment outcomes in cancer patients. A number of other studies have shown an association between VeriStrat status and clinical outcomes in second and subsequent lines of therapy. The prognostic properties of VeriStrat were demonstrated in the placebo arms of two randomized studies in non-small cell lung cancer (NSCLC): TOPICAL and BR.

Downregulation of miR-99a/let-7c/miR-125b miRNA cluster predicts clinical outcome in patients with unresected malignant pleural mesothelioma.

Malignant pleural mesothelioma (MPM) is an aggressive tumor with a dismal overall survival (OS) and to date no molecular markers are available to guide patient management. This study aimed to identify a prognostic miRNA signature in MPM patients who did not undergo tumor resection. Whole miRNA profiling using a microarray platform was performed using biopsies on 27 unresected MPM patients with distinct clinical outcome: 15 patients had short survival (OS<12 months) and 12 patients had long survival (OS>36 months).

Circulating Cell-Free DNA and Circulating Tumor Cells as Prognostic and Predictive Biomarkers in Advanced Non-Small Cell Lung Cancer Patients Treated with First-Line Chemotherapy.

Cell-free DNA (cfDNA) and circulating tumor cells (CTCs) are promising prognostic and predictive biomarkers in non-small cell lung cancer (NSCLC). In this study, we examined the prognostic role of cfDNA and CTCs, in separate and joint analyses, in NSCLC patients receiving first line chemotherapy. Seventy-three patients with advanced NSCLC were enrolled in this study.

Circulating Tumor DNA Reflects Tumor Metabolism Rather Than Tumor Burden in Chemotherapy-Naive Patients with Advanced Non-Small Cell Lung Cancer: F-FDG PET/CT Study.

We aimed to evaluate the relationships between circulating tumor cells (CTCs) or plasma cell-free DNA (cfDNA) on one side and a comprehensive range of F-FDG PET/CT-derived parameters on the other side in chemotherapy-naive patients with advanced non-small cell lung cancer (NSCLC). From a group of 79 patients included in a trial evaluating the role of pretreatment circulating tumor markers as predictors of prognosis in chemotherapy-naive patients with advanced NSCLC, we recruited all those who underwent F-FDG PET/CT for clinical reasons at our institution before inclusion in the trial (and thus just before chemotherapy). For each patient, a peripheral blood sample was collected at baseline for the evaluation of CTCs and cfDNA.

Investigational drugs targeting fibroblast growth factor receptor in the treatment of non-small cell lung cancer.

Fibroblast growth factor receptor (FGFR) due to its central role in regulating cell survival, is a promising target for cancer therapeutics. Dysregulation of the FGFR pathway has been observed in several malignancies, including non-small cell lung cancer (NSCLC) particularly in patients with squamous histology. Areas covered: The aim of this article is to review the most relevant findings of clinical trials investigating drugs targeting FGFR pathway: such as FGFR tyrosine kinase inhibitors (TKIs), FGFR monoclonal antibodies and FGF ligand traps in NSCLC patients.

Releasing the brake: safety profile of immune check-point inhibitors in non-small cell lung cancer.

Immune check-point inhibitors are now employed as single-agents in current practice for the treatment of advanced non-small cell lung cancer (NSCLC), while combinations of different inhibitors are being evaluated in clinical trials. Although the safety profile of these compounds, with particular reference to drugs targeting programmed death protein 1 (PD-1) and its ligand (PD-L1), is generally considered manageable, peculiar, immune-related toxicities may onset. Areas covered: This review focuses on the immune-related adverse events (irAEs) observed during immune check-point blockade in NSCLC and their management.

Whole exome sequencing of independent lung adenocarcinoma, lung squamous cell carcinoma, and malignant peritoneal mesothelioma: A case report.

The presence of multiple primary tumors (MPT) in a single patient has been identified with an increasing frequency. A critical issue is to establish if the second tumor represents an independent primary cancer or a metastasis. Therefore, the assessment of MPT clonal origin might help understand the disease behavior and improve the management/prognosis of the patient.

New systemic strategies for overcoming resistance to targeted therapies in non-small cell lung cancer.

Although the achievements in the treatment of advanced non-small cell lung cancer (NSCLC) have been translated in improved disease control, response rate and survival, especially in the case of patients with targetable oncogenic drivers, acquired resistance is common after initial benefit; furthermore, primary resistance can occasionally be observed. Due to its clinical implications, the management of treatment-resistant NSCLC is a top topic of the current research, and many efforts are being put in the study of the mechanisms at the base of resistance and in the development of effective therapeutic countermeasures. Areas covered: This review aims at identifying the most relevant novel chemical therapies designed to overcome resistance in NSCLC, including recently approved agents, as well as compounds in clinical development.

Fibroblast Growth Factor Receptor (FGFR): A New Target for Non-small Cell Lung Cancer Therapy.

Lung cancer is still the leading cause of cancer related death worldwide. Fibroblast growth factor receptor (FGFR) is a tirosine-kinase receptor that is seen to be amplified or mutated in non-small cell lung cancer (NSCLC) and it plays a crucial role in tumour development and maintenance. The authors analyzed the state of the art of FGFR by reviewing the current literature.
