Tumor stroma-immune interactions shape the immunosuppressive microenvironment and predict response to neoadjuvant chemoradiotherapy plus immunotherapy in rectal cancer

Background
The tumor microenvironment, particularly the tumor stroma, plays a critical role in tumor progression, immune evasion, and therapeutic resistance. However, its interaction with the immune landscape in rectal cancer (RC) remains incompletely…

Combined circulating tumor antigen model demonstrates additional prognostic value in first-line treatment of non-small cell lung cancer

Background
Circulating tumor antigens (ctA; tumor markers) are blood-based proteins that can offer prognostic value in non-small cell lung cancer (NSCLC) and may serve as potential early surrogates for survival. Given the significantly reduced testing…

Multi-omic characterization of 14q deletion in renal clear cell carcinoma identifies EDNRB as a predictor of immunotherapy response

Background
Although chromosome 14q deletion (14q–) is present in up to 40% of clear cell renal cell carcinoma (ccRCC) cases, its immunologic and molecular impact remains unclear. Because TRAF3 and NFKBIA, key regulators of nuclear factor kappa-l…

Plasma proteomics predicts pathological complete response and reveals LIF as a potential mediator of resistance to neoadjuvant immunochemotherapy in resectable NSCLC

Background
Neoadjuvant immunochemotherapy (nICT) is increasingly used for resectable non-small cell lung cancer (NSCLC), yet a substantial proportion of patients fail to achieve pathological complete response (pCR). Clinically scalable, minimally inva…

Clinical significance of CD161+CD8+ T cells in the tumor microenvironment of esophageal squamous cell carcinoma and their association with the 4-1BB signaling pathway

Background
CD161+CD8+ T cells, a cytotoxic T cell subset, remain poorly defined in terms of their clinical significance and functional role in esophageal squamous cell carcinoma (ESCC), which has limited the advancement of precision immunotherapy stra…

UDP-glucuronate decarboxylase 1 promotes tumor immune evasion by accelerating KMT2D loss in hepatocellular carcinoma

Background
Immune checkpoint blockade (ICB) targeting the programmed cell death 1 (PD-1)/programmed cell death ligand 1 (PD-L1) axis has shown promise in hepatocellular carcinoma (HCC), but clinical responses are often limited in durability. Identifyi…

Blood-based kinase activity profiling to predict response to immune checkpoint inhibitors in patients with advanced stage NSCLC: the prospective IOpener study

Background
The programmed death-ligand 1 (PD-L1) tumor proportion score (TPS) is used as a biomarker to predict benefit from immune checkpoint blockade (ICB) in patients with non-small cell lung cancer (NSCLC). However, additional biomarkers are neede…

Artificial intelligence-guided analysis of the tumor microenvironment predicts response to pembrolizumab in rare tumors

Background
Pathologic tumor response and changes in the tumor microenvironment (TME) predict outcomes to immune checkpoint inhibitors, but are understudied in rare tumors. We investigated whether artificial intelligence (AI)-powered analyses of pretre…

Predicting immune-related thyroiditis using polygenic risk scores in patients with advanced melanoma

Background
Inherited genetic variation may impact patient response and risk of toxicity following immune checkpoint inhibitor (ICI) therapy.

Methods
We conducted an agnostic genome-wide analysis study for inherited genetic variants that may predict t…
