Transformer-based AI approach to unravel long-term, time-dependent prognostic complexity in patients with advanced NSCLC and PD-L1 >=50%: insights from the pembrolizumab 5-year global registry

Background
With nearly one-third of patients with advanced non-small cell lung cancer (NSCLC) and PD-L1 Tumor Proportion Score≥50% surviving beyond 5 years following first-line pembrolizumab, long-term outcomes challenge traditional paradigms of ca…

Addition of oncolytic virotherapy to clinical isolated limb perfusion for melanoma and sarcoma activates antitumor immunity

Background
We previously showed that oncolytic virotherapy delivered by isolated limb perfusion (ILP), combined with immune checkpoint inhibition, prevents both local tumor progression and systemic metastases in an animal sarcoma model.

Methods
We de…

Targeting SQLE-mediated cholesterol metabolism to enhance CD8+ T cell activation and immunotherapy efficacy in hepatocellular carcinoma

Background
The sustained effectiveness of anti-programmed cell death protein-1 (PD1) treatment is limited to a subgroup of patients with hepatocellular carcinoma (HCC) due to the tumor microenvironment heterogeneity, highlighting the need to identify …

Novel oncolytic adenovirus-based PEPvIII vaccine displays a super antitumor effect in glioma models

Background
Currently, an epidermal growth factor receptor variant III (EGFRvIII)-specific peptide (PEPvIII) vaccine has not achieved satisfactory outcomes in several clinical trials for glioblastoma. This is probably due to the poor immunogenicity of …

High Treg and PMN-MDSC densities are a hallmark of tertiary lymphoid structures in fatal cases of cervical cancer

Background
High densities of tertiary lymphoid structures (TLSs) are associated with improved clinical outcomes in various malignancies, including human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC). However, the role o…

Tertiary lymphoid structures in Merkel cell carcinoma facilitate naïve and central memory T-cell infiltration linked to immunotherapy response

Background
The presence of tertiary lymphoid structures (TLS) in solid tumors, including Merkel cell carcinoma (MCC), is associated with a better prognosis and a better response to immunotherapy with immune checkpoint inhibition (ICI). The detailed me…

Second signals for cancer immunotherapy

Recent years have seen renewed appreciation of the critical role played by the prototypic T cell co-stimulatory receptor CD28 in cancer immunotherapy. Inhibition of co-stimulation by direct competition, as exemplified by cytotoxic T-lymphocyte associa…
