Background: ICIs are used in the management of several malignancies. However, they can result in immune-related adverse events, such as colitis. The aim of this study is to obtain an epidemiological survey of patients who develop immune checkpoint inhibitor (ICI)-induced colitis and identify underlying risk factors.
Methods: A cohort study was performed using Explorys, a US-based population database. Our cohort included all patients in a five-year interval on an ICI. We further identified those who developed colitis after initiating an ICI. Demographic data and possible risk factors were assessed. Odds ratios were calculated and multivariable statistical analysis was performed.
Results: 3.6% of patients developed ICI-induced colitis. Women [OR: 1.2; 95% CI 1.224-1.231, p <0.001], Caucasians [OR: 2.3; 2.284 - 2.299], individuals older than 65 years [OR: 1.3; 1.319 - 1.326], obese patients [OR: 3.3; 3.273 - 3.302], and those with a history of alcohol abuse [OR: 2.5; 2.485 - 2.523] were more likely to develop colitis. Patients who received Nivolumab [OR: 2.8; 2.563 - 3.022], Ipilimumab [OR: 4.9; 3.937 - 6.061], Pembrolizumab [OR 2.7; 2.463 - 2.868], and Atezolizumab [OR 2.9; 2.430 - 3.388] had an increased odds of developing colitis. The majority of cases were diagnosed in the first 6 months of therapy.
Conclusions: This is the largest study to describe the epidemiology of ICI-induced colitis and it is the first to identify underlying risk factors. Ipilimumab poses the greatest risk for ICI-induced colitis. The risk of colitis should be discussed with all patients prior to initiating an ICI, as it may be a factor in choosing among ICIs.

The heat shock protein 90 (Hsp90) family of molecular chaperones mediates the folding and activation of ~ 400 client proteins, many of which contribute to oncogenesis. As a result, Hsp90 pan-inhibitors, which inhibit all four Hsp90 isoforms, have been investigated in the clinic for the treatment of cancer. Unfortunately, detrimental side effects were observed and hindered the clinical development of pan-Hsp90 inhibitors.

Autoimmune liver diseases (AILD) involve dysregulated CD4 T cell responses against liver self-antigens, but how these autoreactive T cells relate to liver tissue pathology remains unclear. Here we perform single-cell transcriptomic and T cell receptor analyses of circulating, self-antigen-specific CD4 T cells from patients with AILD and identify a subset of liver-autoreactive CD4 T cells with a distinct B-helper transcriptional profile characterized by PD-1, TIGIT and HLA-DR expression. These cells share clonal relationships with expanded intrahepatic T cells and exhibit transcriptional signatures overlapping with tissue-resident T cells in chronically inflamed environments.

Immune checkpoint blockade (ICB) combined with radiotherapy (RT) has improved patients survival, but also increased the risk of pulmonary adverse effects (AEs). Therefore, to explore potential drug targets for interstitial lung disease (ILD), we investigated the interaction of ICB and RT in pulmonary AEs using the disproportionality analysis and COX regression. Genome-wide association studies, transcriptome analysis, and vivo models highlighted the role of programmed death-ligand-1 (PD-L1) in ILD.

Background: The integration of immune checkpoint inhibitors (ICIs) into routine gynecologic cancer treatment requires a thorough understanding of how to manage immune-related adverse events (irAEs) to ensure patient safety. However, reports on real-world clinical experience in the management of ICIs in gynecologic oncology are very limited. The aim of this survey was to provide a real-world overview of the experiences and the current state of irAE management of ICIs in Germany, Switzerland, and Austria.

Non-small cell lung cancer (NSCLC) remains a dire disease being the first cause of cancer death among both genders. Early-stage NSCLC often has better treatment outcomes despite it being a highly heterogeneous disease. So far, the neo-adjuvant chemotherapy strategies have led to a small benefit with an improvement of 5% in overall survival as an absolute benefit.
