Coming soonPD-L1 positive squamous cell carcinoma of the head and neck is an epithelial malignancy arising from the mucosal linings of the upper aerodigestive tract, including the oral cavity, pharynx, larynx, and sinonasal tract.
It is pathologically characterized by the immunohistochemical expression of programmed death-ligand 1 (PD-L1) on tumor cells, tumor-infiltrating lymphocytes, and histiocytes, typically defined by a combined positive score or tumor proportion score above a validated threshold.
This biomarker positivity reflects an immunosuppressive tumor microenvironment where PD-L1 engages PD-1 receptors on cytotoxic T cells, promoting immune evasion and tumor survival.
Commonly associated with tobacco, alcohol exposure, or oncogenic human papillomavirus infection, this molecularly defined subset frequently presents as locally aggressive or recurrent disease with a heightened susceptibility to targeted immune checkpoint inhibition.
