Tumor immune microenvironment delineates progression trajectories of distinct nasopharyngeal carcinoma phenotypes.

ABSTRACT: We investigate the molecular landscape of locally advanced nasopharyngeal carcinoma (LA-NPC) subtypes: limited (L), ascending (A), descending (D), and ascending-descending (AD). Using a cohort of 994 patients, we perform germline and somatic whole-exome sequencing (WES), transcriptomic profiling, multiplex immunohistochemistry (mIHC), and spatial histopathological analyses of tumor whole-slide images (WSIs). Germline WES reveals the most variants in AD subtypes, but somatic WES shows no subtype-specific mutations. Transcriptomics reveals higher extracellular matrix (ECM) gene expression in A and AD subtypes and higher immune gene expression in D and AD subtypes, agreeing with deconvolution and mIHC.
