Background: Black patients were severely under-represented in the clinical trials that led to the approval of immune checkpoint inhibitors (ICIs) for all cancers. The aim of this study was to characterise the effectiveness and safety of ICIs in Black patients.

Methods: We did a retrospective cohort study of patients in the US Veterans Health Administration (VHA) system's Corporate Data Warehouse containing electronic medical records for all patients who self-identified as non-Hispanic Black or African American (referred to as Black) or non-Hispanic White (referred to as White) and received PD-1, PD-L1, CTLA-4, or LAG-3 inhibitors between Jan 1, 2010, and Dec 31, 2023.

Background: The cumulative, health system-wide survival benefit of immune checkpoint inhibitors (ICIs) is unclear, particularly among real-world patients with limited life expectancies and among subgroups poorly represented on clinical trials. We sought to determine the health system-wide survival impact of ICIs.

Methods: We identified all patients receiving PD-1/PD-L1 or CTLA-4 inhibitors from 2010 to 2023 in the national Veterans Health Administration (VHA) system (ICI cohort) and all patients who received non-ICI systemic therapy in the years before ICI approval (historical control).

Lung cancer is responsible for a high burden of disease globally. Over the last two decades, the discovery of targetable oncogenic genomic alterations has revolutionized the treatment landscape for early-stage and advanced non-small cell lung cancer (NSCLC). New molecular drivers continue to emerge as promising therapeutic targets, including KRAS non-G12C, RAF/MEK, HER3, Nectin-4, folate receptor alpha, ITGB6, and PRMT5.

Introduction: Patients with advanced ALK-positive NSCLC typically have poor response to immunotherapy; the benefit of consolidation durvalumab in patients with unresectable stage III ALK-positive NSCLC remains unclear. Herein, we compare the efficacy and safety of consolidation ALK tyrosine kinase inhibitor (TKI) versus durvalumab or observation after concurrent chemoradiation.

Methods: We conducted a retrospective study using a multicenter study of 17 institutions globally.

Background And Aims: The change in hepatocellular carcinoma (HCC) care continuum during the coronavirus disease 2019 (COVID-19) pandemic remains unknown at a national level in the United States. We sought to determine the impact of the pandemic on incident HCC cases, clinical characteristics, and treatment in the United States.

Methods: Using the National Cancer Database, we analyzed incident HCC cases from 2010 to 2020.
