Epstein-Barr virus infection in ex vivo tonsil epithelial cell cultures of asymptomatic carriers. Are male Eat a diet rich in salt-cured fish and meats Have a family history of nasopharyngeal cancer Have certain genes linked to cancer development Have come in contact with EBV Some, but not all, studies have found a higher risk of nasopharyngeal cancer in people who: In addition to these factors, the presence of nitrosodiethyl amine in smoke and dried meat and the use of herbal nasal medicine are well-known risk factors of NPC. Report of a case-control study in Hong Kong".

Arina Ikasari for supporting some of the data on LMP1.
Here, we presented our data about the incidence of NPC in Indonesia using pathologic reports from 13 university centers in Indonesia collected in the Pathology Cancer Registry System. The nasopharyngeal primary tumor is rarely biopsied. If the exam is abnormal, your doctor may recommend a biopsy.
Etiological factors include Epstein-Barr virus EBVgenetic susceptibility and consumption of food with possible carcinogens — volatile nitrosamines. Cipto Mangunkusumo Hospital, NPC incidence in all patients treated between and and assessed the epidemiologic and clinical data of patients in which additional markers for NPC were examined.
However, in childhood the presence of metastatic disease in cervical lymph nodes at diagnosis does not adversely affect prognosis [ 30 - 33 ]. Educating regional health workers and hospital staff is a critical first step for controlling NPC at early stage. These tests were routinely performed at diagnosis, during treatment, and during follow-up after histological verification. Sardjito Hospital at the Gadjah Mada University in Yogyakarta, a more rural region of Mid-Java, where cases were recently analyzed Hariwiyanto B; unpublished data and personal communication.
A biopsy may be taken during the nasopharyngoscopy. The World Health Organization classifies nasopharyngeal carcinoma in three types. World Health Organization; Individual EBV genes associated with the three main latency programs of EBV can contribute to the malignant phenotype, albeit in a different fashion in distinct tumor types .
Nasopharyngeal carcinoma in Indonesia: epidemiology, incidence, signs, and symptoms at presentation
Although most patients in our study are of Javanese origin, it became clear that other ethnic groups in the overall population of Indonesia are also affected by NPC. In particular, in Tunisia the incidence is relatively high [ nasofarin ]. Treatment is given in two phases: Cytochrome P 2A6 polymorphism in nasopharyngeal carcinoma. Nasopharyngeal cancer is also called nasopharyngeal carcinoma NPC.
In our cases, we found a similar predominance, with Basically, examination and biopsies of the tumor and the nasopharynx need to be performed by a direct nasoendoscopic examination preferably using flexible fibreoptic endoscope.
It is also much more common in: Nasopharyngeal cancer among young people in the United States: The throat pharynx is a muscular tube that runs from the back of your nose down into your neck.
DA - 4: Clinical signs and symptoms at presentation Most patients in our study cohort presented with advanced disease. However, more recent large-scale studies with appropriate local non-NPC controls have cast doubt on these early findings, and no clear NPC-related EBV strain nor limited number genetic marker has been identified as outstanding entity .
Urea, electrolyte, creatinine, liver function, Ca, PO 4alkaline phosphate.
Etiology NPC is the commonest epithelial cancer in adults. Childhood nasopharyngeal carcinoma is usually a disease of adolescence. You nasofring more likely to get this type of cancer if you: A prior study by Devi et al.
Nasopharynx cancer - Wikipedia
Nasopharyngeal carcinoma NPC is a tumor arising from the epithelial cells that cover the surface and line the nasopharynx. Imaging tests can help spot nasopharyngeal cancer or determine if it has spread. Nasopharyngeal carcinoma NPC is caused by a combination of factors: Treatment Surgery Due to the anatomical position of NPC and its tendency to present with cervical lymph node metastases, it is not amenable to surgery for local control.
