Frontline immunotherapy with response-guided subsequent treatment (FIRST) in cutaneous squamous cell carcinoma: a Bayesian causal analysis of dose intensity, early benefit, and treatment de-escalation

Background
Programmed death receptor 1 (PD-1) blockade produces high response rates in resectable and locally advanced cutaneous squamous cell carcinoma (CSCC), but how many doses are needed and whether surgery or radiation after immunotherapy (consol…

Spatial architecture of tertiary lymphoid structures represents an independent prognostic dimension in hepatocellular carcinoma

Background and aims
Tertiary lymphoid structures (TLS) are associated with heterogeneous outcomes in hepatocellular carcinoma (HCC), but whether their anatomical context determines clinical impact remains unknown. We hypothesized that spatial compartm…

Blautia coccoides-derived acetate potentiates anti-PD-1 immunotherapy in melanoma by activating cytotoxic CD8+ T cells

Background
Gut microbiota can modulate cancer immunotherapy and enhance the efficacy of programmed cell death protein 1 (PD-1) blockade in tumors, yet the responsible microbes and underlying mechanisms remain incompletely understood.

Methods
Publicly…

Diverse origin and nature of tumor-infiltrating lymphocytes: the infection hypothesis

In the 19th century, Rudolf Virchow observed lymphocyte infiltration in tumors and suggested a potential link between cancer and inflammation. Current explanations for the origin of tumor-infiltrating lymphocytes are based on the interaction between c…

Sleeping Beauty mutagenesis identifies BACH2 and other regulators of CD8+ T-cell exhaustion, persistence in vivo, and CAR-T cell function under tumor-associated chronic antigen stimulation

Background
Genes that enhance T-cell function represent promising targets for improving engineered T-cell therapies for cancer. While extensive CRISPR knockout screens have identified key genes enhancing T-cell persistence, employing Sleeping Beauty (…

Anti-PD1-IL18 immunoconjugate promotes effector T cell-mediated antitumor immunity

Background
Immune checkpoint inhibitors have revolutionized cancer therapy, yet a substantial proportion of patients exhibit primary or acquired resistance. Immunocytokines offer a strategy to enhance antitumor immunity by delivering cytokine signals …

LysoPS-GPR34 axis enhances tumor-associated macrophages efferocytosis to promote immune escape in gastric cancer peritoneal metastasis

Background
Metabolites sculpt the immunosuppressive tumor microenvironment (TME) that facilitates immune evasion. As a crucial signaling lysophospholipid, lysophosphatidylserine (LysoPS) correlates with advanced disease stages in multiple tumor types….

BCL-2/BCL-xL inhibitor pelcitoclax with osimertinib for EGFR-mutated advanced non-small-cell lung cancer: a phase 1b trial

Background
Overcoming tyrosine kinase inhibitor (TKI) resistance improves survival in advanced epidermal growth factor receptor (EGFR)-mutated non-small-cell lung cancer (NSCLC). We therefore examined the safety and preliminary efficacy of pelcitoclax…

Adjuvant penpulimab in very-high risk clear cell renal cell carcinoma: a prospective, non-randomized, controlled phase II trial with integrated plasma multi-omics analyses

Purpose
Patients with very-high risk clear cell renal cell carcinoma (ccRCC) remain at substantial risk of recurrence after nephrectomy. However, heterogeneity in benefit from adjuvant immunotherapy observed in the KEYNOTE-564 trial, together with lim…
