The hunt for the perfect biomarker in nasopharyngeal carcinoma—the RRAS “race” beyond Epstein-Barr virus?

Nasopharyngeal carcinoma (NPC) is a distinct malignancy from other epithelial head and neck cancers, given its specific geographical and demographic distribution.

The endemic variant of NPC is invariably associated with the Epstein-Barr virus (EBV).
