Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with newly diagnosed stages III-IVb (UICC 2002) nasopharyngeal carcinomas, will be recruited.

You may not qualify if:

  • Patients with local invasion or metastatic foci in salivary glands, detected by MRI and positron emission computed tomography(PET-CT) prior to treatment, were excluded, as were patients suffering from diseases, such as Sjogren's syndrome, or with a history of surgery to major salivary glands, or prior head and neck radiotherapy.
