Nasopharyngeal carcinoma is a rare type of head and neck cancer. It starts in the upper part of your throat, behind the nose. This area is called the nasopharynx. The nasopharynx is precariously placed at the base of your skull, above the roof of your mouth.The malignancy of nasopharyngeal cancer has an intermediate incidence of five to nine cases per 100,000 population per year in inhabitants of Israel. Radiotherapy is administered to the gross tumor volume (GTV) or disease in the primary site and neck adenopathy.
The initial clinical target volume (CTV) includes the GTV and all sites of potential subclinical disease to a dose of 45-50.4 Gy at 1.8-2 Gy/fraction. Approaches to primary prevention of NPC remain under consideration. Thus, there is a need to conduct secondary prevention, such as improving rates of early detection, early diagnosis, and early treatment in NPC patients. Achievements in these areas might bring hope of providing a successful screening model in cancer.
