Perioperative pembrolizumab in early-stage non-small cell lung cancer (NSCLC): conventional and distribution-based immune profiling of the tumor microenvironment and peripheral circulation

Purpose
A recently published phase 2 neoadjuvant trial in patients with early-stage non-small cell lung cancer (NSCLC) (NCT02818920) evaluated the potential efficacy of pembrolizumab administration in the absence of chemotherapy. This communication re…

Clonally expanded effector CD4+ cytotoxic T lymphocytes are associated with severe neurological adverse events after immune checkpoint inhibitor therapy

Background
Immune checkpoint inhibitor (ICI) therapies present a pillar of modern cancer therapy but can cause neurological immune-related adverse events (n-irAEs), of which up to 35% are severe or even fatal. However, the detailed immunological mecha…

Efficacy of immunotherapy in gastrointestinal (GI) tumors with mismatch repair deficient (MMRd) unusual phenotype: an AGEO real-world study

Background
Tumors with mismatch repair deficiency (MMRd) classically display concomitant loss of MLH1/PMS2 or MSH2/MSH6 on immunohistochemistry (IHC) with microsatellite instability-high (MSI-High) status on molecular testing. Nevertheless, a differen…

Metagenomic next-generation sequencing unraveled the characteristic of lung microbiota in patients with checkpoint inhibitor pneumonitis: results from a prospective cohort study

Background
Checkpoint inhibitor pneumonitis (CIP) is among the most lethal immune-related adverse events in patients with cancer receiving immunotherapy. This study aims to characterize the lung microbiome in patients with CIP and evaluate its diagnos…

Genetic haplotypes in VWA8, OSBPL6, and ADAMTS9-AS2 are associated with immune-related adverse effects in ICI-treated patients with cancer

Background
Immune-related adverse events (irAEs) remain largely unpredictable, potentially affecting multiple organ systems and occurring at almost any point during and even occasionally after immune checkpoint inhibitor (ICI) treatment. To identify p…

Attention-guided framework for integrative omics and temporal dynamics in predicting major pathological response in neoadjuvant immunochemotherapy for NSCLC

Objective
This study developed a multiomics model combining radiomics, pathomics, and temporal imaging to predict major pathological response in patients with locally advanced non-small cell lung cancer (NSCLC) undergoing neoadjuvant immunochemotherap…

Pan-microbial serological repertoire as a biomarker of immunotherapy response in hepatocellular carcinoma

Immune checkpoint inhibition (ICI) has become a first-line treatment strategy for advanced hepatocellular carcinoma (HCC). However, treatment efficacy remains varied, and there are no reliable biomarkers of response. We used phage immunoprecipitation …

Pre-existing infiltration with T cells and CD14+ myeloid cells is associated with treatment response to imiquimod in primary and recurrent vulvar high-grade squamous intraepithelial lesions

Imiquimod is a standard therapy option for vulvar high-grade squamous intraepithelial lesions (vHSIL). In a retrospective study, the pre-existing composition of the immune cell infiltrate was associated with clinical outcome after imiquimod treatment….

ALCAM-CD6 axis suppression: a key determinant of immune-mediated metastasis recurrence in stage III non-small cell lung cancer

Background
Metastatic recurrence poses a significant challenge in cancer treatment, impacting patient survival and prognosis. Understanding the biological mechanisms behind it is essential for improving treatment strategies and patient outcomes. Lung …

Expansion of a circulating Ki67-positive effector T-cell population following combined PD-1 and CTLA-4 blockade for melanoma is predictive of treatment response

Background
Despite the success of combined cytotoxic T-lymphocyte associated protein 4 (CTLA-4) and programmed cell death protein-1 (PD-1) immune checkpoint blockade (cICB), the majority of patients with melanoma fail to respond or experience severe t…
