nasopharyngeal cancer

nasopharyngeal carcinoma

A rare (in the West) malignancy which is endemic in regions of southern China—where it comprises up to 18% of cancers—as well as in southeast Asia. It is linked to EBV infection, diets high in nitrosamines and inhaled carcinogens. It is more common in males and has a peak incidence of age 40 to 50.

Lymphoma (DLCBL, Hodgkin's), reactive lymphoid proliferation, sarcomas.

Radiotherapy, chemotherapy.

Stage dependant; 5-year survival is 55%.

  • Differentiated
  • Undifferentiated
- Basaloid squamous cell carcinoma
- Nasopharyngeal cancer, staging
  • Stage I—Lesion confined to nasopharynx.
  • Stage II
    A) Lesion extends to oropharynx and/or nasal fossa.
    B) Lesion extends to nearby lymph nodes or to parapharyngeal region.
  • Stage III—Lesion spread to lymph nodes on both sides of the neck or nearby bones or sinuses.
  • Stage IV
    A) Spread beyond nasopharynx to other areas in head; possible spread to regional lymph nodes.
    B) Spread beyond nasopharynx to other areas in head and to lymph nodes above clavicle, or are ≥ 6 cm in greatest dimension.

nasopharyngeal carcinoma

Nasopharyngeal cancer A rare malignancy, which is endemic to regions of southern China and Southeast Asia; persons with serologic markers for EBV–IgA antibodies against EBV capsid antigen and/or neutralizing antibodies against EBV-specific DNase have a 3-fold cumulative risk of nasopharyngeal cancer if one marker was positive and a 35-fold risk if both markers are positive. See Epstein-Barr virus.
