NPC occurs in children and adults. NPC differs significantly from other cancers of the head and neck in its occurrencecauses, clinical behavior, and treatment.

It is vastly more common in certain regions of East Asia and Africa than elsewhere, with viraldietary and genetic factors implicated in its causation. It is most common in males. It is a squamous cell carcinoma or an undifferentiated type. Squamous epithelial cells are a flat type of cell found in the skin and the membranes that line some body cavities. Differentiation means how different the cancer cells are from normal cells. Undifferentiated cells are cells that do not have their mature features or functions.

Swelling of the lymph nodes in the neck is the initial presentation in many people, and the diagnosis of NPC is often made by lymph node biopsy. Signs and symptoms related to the primary tumor include trismuspain, otitis medianasal regurgitation due to paresis loss of or impaired movement of the soft palatehearing loss and cranial nerve palsy paralysis. Larger growths may produce nasal obstruction or bleeding and a “nasal twang”. Metastatic spread may result in bone pain or organ dysfunction.

Rarely, a paraneoplastic syndrome of osteoarthropathy diseases of joints and bones may occur with widespread disease. Nasopharyngeal carcinoma NPC is caused by a combination of factors: The World Health Organization does not have set preventative measures for this virus because it is so easily spread and is worldwide.

Very rarely does Epstein-Barr virus lead to cancer, which suggests a variety of influencing factors. Other likely causes include genetic susceptibility, consumption of food in particular salted fish [4] containing carcinogenic volatile nitrosamines.

The cause of NPC particularly the endemic form seems to follow a multi-step process, in which EBV, ethnic background, and environmental carcinogens all seem to play an important role. More importantly, EBV DNA levels appear to correlate with treatment response and may predict disease recurrence, suggesting that they may be an independent indicator of prognosis. The mechanism by which EBV alters nasopharyngeal cells is being elucidated [8] to provide a rational therapeutic target.

The World Health Organization classifies nasopharyngeal carcinoma in three types. Type 1 I is keratinizing squamous cell carcinoma. Type 2a II is non-keratinizing squamous cell carcinoma. Type 2b III is undifferentiated carcinoma. Staging of nasopharyngeal carcinoma is based on clinical and radiologic examination.

Stage II is a tumor extending in the local area, or that with any evidence of limited rhinopyarynx nodal disease. Stage III is a large tumor with or without neck disease, or a tumor with bilateral neck disease. Ccancer carcinoma can be treated by surgery, by chemotherapyor by radiotherapy. The expression of EBV latent proteins within undifferentiated nasopharyngeal carcinoma can be potentially exploited for immune-based therapies. Nasopharynx cancer as of resulted in 65, deaths globally up from 45, in NPC is uncommon in the United States and most other nations, representing less than vu case perin most populations.

The cause of increased risk for NPC in these endemic regions is not clear. From Wikipedia, the free encyclopedia. Retrieved 2 October Seminars in Cancer Biology. Report of a case-control study in Hong Kong”. The Journal of Pathology.
