Introduction: Several studies have sought to determine the prevalence of BRCA1/BRCA2 in patient populations, but few have studied impacts of such alterations on patient outcomes beyond breast, ovarian, prostate and pancreatic cancers. This study assessed patient outcomes from a large real-world evidence (RWE) database for patients with EGFR-mutated advanced non-small-cell lung cancer (aNSCLC) who also had incidental pathogenic germline variants (iPGVs) in BRCA1, BRCA2 or PALB2 identified by a well-validated liquid biopsy.
Materials And Methods: Outcomes from patients included in GuardantINFORM, a RWE database, from Oct 2018-June 2024 with a diagnosis of aNSCLC and an incidental pathogenic germline variant (iPGV) in BRCA1/2 or PALB2 included in OncoKB treated with EGFR monotherapy (gBRCA/PALB2+) were matched in 1:5 using coarsened exact matching to a control cohort without iPGVs (control).
Background: Brigatinib, a selective ALK inhibitor, demonstrated preclinical activity against a range of crizotinib-resistant ALK alterations in NSCLC. We examined associations between brigatinib efficacy and tumor- and plasma-detected driver mutations in crizotinib-resistant ALK fusion-positive NSCLC.
Patients And Methods: Tumor tissue and plasma circulating tumor DNA (ctDNA) from patients with crizotinib-exposed ALK-positive NSCLC receiving brigatinib in phase 1/2 and phase 2 ALTA trials were analyzed by next-generation sequencing.
Introduction: Prior studies evaluating the efficacy of first line (1 L) immune checkpoint inhibitor (ICI) monotherapy or combined chemoimmunotherapy in advanced NSCLC found improved outcomes with chemoimmunotherapy independent of PD-L1 and KRAS mutation status. As such, combined chemoimmunotherapy was proposed as the preferred comparator arm for 1 L trials in KRAS mutated (KRAS mt) NSCLC. Herein, we report a multimodal, real world data (RWD) analysis for outcomes with 1 L therapy in patients with advanced NSCLC stratified by KRAS mutation status and PD-L1 levels.

We evaluated the impact of plasma TF on mutation detection and clinical outcomes in patients with previously treated, advanced non-small cell lung cancer on the Lung Master Protocol (Lung-MAP).

We present a patient with echinoderm microtubule-associated protein-like 4 () and fusion protein-positive mNSCLC who developed severe hypoxemia and pneumonitis requiring intubation within 2 days of initiating brigatinib therapy. The workup for alternative etiologies of respiratory distress was unrevealing, and the patient was treated for presumed brigatinib-induced pneumonitis with high-dose methylprednisolone.

Still, the survival benefit of immune-checkpoint inhibitors is modest, and there is concern about drug toxicity. In addition, there is ongoing exploration into combination therapy involving immune-checkpoint inhibitors, which come at the risk of increased toxicity.
View Article and Find Full Text PDFPurpose: Broad-based molecular testing with next-generation sequencing (NGS) is now the standard of care in advanced non-small cell lung cancer (NSCLC). Two approaches to molecular testing are (1) reflexive testing at pathologic NSCLC confirmation, often using an in-house molecular panel, and (2) send-out testing to private vendors, ordered by a clinician. This study explored the outcomes with reflex versus send-out testing.

The objective of this document is to review the literature and present consensus among a group of multidisciplinary experts to guide the determination of resectability and management of locally advanced non-small cell lung cancer (NSCLC) in the context of contemporary evidence.
Methods: The Society of Thoracic Surgeon Workforce on Thoracic Surgery assembled a multidisciplinary expert panel composed of thoracic surgeons and medical and radiation oncologists with established expertise in the management of lung cancer.
Background: Stereotactic body radiotherapy (SBRT) is safe and effective for treatment of extracranial metastatic disease, but its safety when combined with immune checkpoint inhibitors (ICI) has not yet been comprehensively reported. Here we report adverse events (AEs) associated with combined SBRT and ICI using prospectively-collected data on patients in three trials investigating multi-site SBRT combined with ICI.
Methods: Patients were included from three prospective trials of ICI (pembrolizumab; nivolumab/urelumab or nivolumab/cabiralizumab; nivolumab/ipilimumab) with SBRT to 1-4 sites.
Introduction: A dynamic molecular biomarker that can identify early efficacy of immune checkpoint inhibitor (ICI) therapy remains an unmet clinical need. Here we evaluate if a novel circulating tumor DNA (ctDNA) assay, xM, used for treatment response monitoring (TRM), that quantifies changes in ctDNA tumor fraction (TF), can predict outcome benefits in patients treated with ICI alone or in combination with chemotherapy in a real-world (RW) cohort.
Methods: This retrospective study consisted of patients with advanced cancer from the Tempus de-identified clinical genomic database who received longitudinal liquid-based next-generation sequencing.
Despite the high activity of selective RET inhibitors in RET-driven NSCLC, resistance eventually develops and there is unmet need to better define therapeutic options for patients. This is a case of a patient initially thought to have no targetable alterations, then found to have a RET fusion, and subsequently HER2 amplification on three distinct biopsies. She was treated initially with chemotherapy and immune therapy, then switched to selpercatinib, and eventually had fam-trastuzumab deruxtecan added to selpercatinib.

Methods: The TERAVOLT database is an international, multi-center repository of cross-sectional and longitudinal data studying the impact of COVID-19 on individuals with thoracic malignancies. Patients from North America with thoracic malignancies and confirmed COVID-19 infection were included for this analysis of racial and ethnic disparities.
Patients with metastatic epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) are widely treated with osimertinib, the preferred first-line treatment option. However, disease progression inevitably occurs, driven by EGFR-dependent or EGFR-independent mechanisms of resistance. Platinum-based chemotherapy is the recommended treatment following progression with osimertinib but responses to platinum-based chemotherapy are transient.

Purpose: Lung Cancer Master Protocol (Lung-MAP), a public-private partnership, established infrastructure for conducting a biomarker-driven master protocol in molecularly targeted therapies. We compared characteristics of patients enrolled in Lung-MAP with those of patients in advanced non-small-cell lung cancer (NSCLC) trials to examine if master protocols improve trial access.
Methods: We examined patients enrolled in Lung-MAP (2014-2020) according to sociodemographic characteristics.
Introduction: Patients with non-small-cell lung cancer (NSCLC) who have never smoked or have tumors with mutations in EGFR generally derive minimal benefit from single-agent PD-1/PD-L1 checkpoint inhibitors. Prior data indicate that adding PD-L1 inhibition to anti-VEGF and cytotoxic chemotherapy may be a promising approach to overcoming immunotherapy resistance in these patients, however prospective validation is needed. This trial in progress (NCT03786692) is evaluating patients with stage IV NSCLC who have never smoked or who have tumors with sensitizing EGFR alterations to determine if a 4-drug combination of atezolizumab, carboplatin, pemetrexed, and bevacizumab can improve outcomes compared to carboplatin, pemetrexed and bevacizumab without atezolizumab.

Improvements in overall survival (OS) in two separate pembrolizumab trials have demonstrated survival improvements over chemotherapy alone, regardless of PD-L1 status. The optimal chemotherapy backbone for combination with immunotherapy is unknown.

Non-small cell lung cancer (NSCLC) represents most of the diagnoses of lung cancer. Vascular endothelial growth factor receptor-2 (VEGFR2) is a member of the VEGF family of receptor tyrosine kinase proteins, which are expressed on both endothelial and tumor cells, are one of the key proteins contributing to cancer development, and are involved in drug resistance.
