Head and neck squamous cell carcinomas (HNSCCs) are the seventh most common cancer represent a global health burden. Immune checkpoint inhibitors (ICIs) have shown promise in treating recurrent/metastatic disease with durable benefit ∼30% of patients. Current biomarkers for HNSCC limited their dynamic ability to capture tumor microenvironment (TME) features an increasing need deeper tissue characterization.
