This is a case-control pilot study. We will recruit 40 patients. 20 patients with newly diagnosed primary NPC will be recruited to the test group. 20 patients undergoing an OGD for lesions not involving disease of the head and neck region will be recruited to the control group. NBI OGD and flexible nasoendoscopy will be performed to examine patients' nasopharyngeal region. NBI OGD: Endoscopic procedures would be performed by our investigators with expertise on performing upper endoscopy. Endoscopes with magnification and NBI function would be used (GF-H290Z, Olympus Medical Corporations, Tokyo, Japan). A soft black hood would be attached to the tip of the endoscope for better focal length adjustment. Upon insertion through a mouthpiece, the scope will then be retroflexed into the nasopharynx and the lateral walls into the Fossa of Rosenmuller and the posterior nasopharyngeal wall will be systematically examined with white light and NBI. Target suspicious areas would be examined by use of magnification with the power up to 80X. Flexible nasoendoscopy: The nasoendoscope is introduced into the nose, the nasal cavity and nasopharyngnx. It has a camera and a light at the end and allows our doctor to check for any abnormal looking areas. Upon identification of suspicious lesion. Biopsies of sites with different NBI findings will be taken to correlate the NBI findings with histological features.
