Overview

If left untreated nasopharyngeal carcinoma produces few symptoms early in course. Non-keratinizing nasopharyngeal carcinoma is associated with a 5 year survival rate of 65%. The common complications of nasopharyngeal carcinoma include airway obstruction, dysphagia and disfigurement of the neck or face.

Natural history

If left untreated nasopharyngeal carcinoma produces few symptoms early in its course. Once the tumor has expanded from its site of origin in the lateral wall of the nasopharynx, it may obstruct the nasal passages and cause nasal discharge or epistaxis.

Prognosis

Non-keratinizing nasopharyngeal carcinoma is associated with a 5 year survival rate of 65%. [1] Prognosis is influenced both by stage and tumour type:

  • Type I: Keratinizing squamous cell carcinoma - 42% 5-year survival
  • Type II: Non-keratinizing squamous cell carcinoma - 65% 5-year survival
  • Type III: Undifferentiated carcinoma - 14% 5-year survival[2]

Complications

Complications of nasopharyngeal carcinoma include:

A potential complications of radiotherapy include:
