Signs and Symptoms of Nasopharyngeal Carcinoma

  • Overview:
    • Nasopharyngeal carcinoma (NPC):
      • Typically presents with a painless upper-neck mass plus nasal, aural, and cranial nerve symptoms:
        • Reflecting the tumor’s origin in the fossa of Rosenmüller with lateral (parapharyngeal) and superior (skull base) spread
    • Early symptoms are non-specific:
      • So most patients present at advanced stage (III to IV)
  • Presenting features by mechanism:
    • Neck mass (regional nodal spread):
      • Most common presentation (~75%):
        • Painless enlarged upper cervical node:
          • Often the first / only sign
      • Retropharyngeal and level II nodes:
        • Are first echelons
      • May occur without a visible primary
    • Nasal symptoms (primary tumor):
      • Epistaxis or blood-tinged discharge
      • Unilateral nasal obstruction
      • Rhinorrhea (nasal dysfunction ~73%)
      • “Nasal twang” or voice change with large tumors
    • Aural / eustachian tube dysfunction:
      • Unilateral serous otitis media
      • Conductive hearing loss
      • Tinnitus
      • Aural fullness (~62%):
        • The feeling of pressure, clogging, or fullness inside the ear:
          • Often described as having water or air trapped inside
    • Skull-base / cranial nerve involvement:
      • Headache (~35%)
      • Facial pain / numbness (CN V)
      • Diplopia (~11%, CN VI)
      • Cranial nerve palsy in ~20% of the cases at diagnosis
      • Most affected nerves:
        • CN V and VI, plus III and XII
        • Advanced disease may cause cavernous sinus syndrome and multiple cranial neuropathies
    • Less common findings:
      • Trismus (~3%, pterygoid muscle invasion)
      • Nasal regurgitation (soft-palate paresis)
      • Symptoms of distant metastasis:
        • Bone, lung, liver
      • Anorexia / weight loss uncommon:
        • If present, raise suspicion for distant spread
  • Evaluation:
    • Complete head and neck exam with nasopharyngeal fiberoptic endoscopy; neck palpation
    • EBV testing:
      • Endemic undifferentiated / nonkeratinizing subtypes strongly EBV-associated
    • Biopsy of nasopharyngeal lesion
    • MRI skull base to clavicle
