Nasopharyngeal cancer markers include EBV-associated markers, extra-EBV markers, etc. These markers are important indicators for screening the disease, and abnormal indicators need to be consulted. 1. EBV-related markers: EBV infection is the main causative factor of non-keratinizing nasopharyngeal carcinoma, including plasma EBV DNA, EBV-encoded miRNA, EBV serum antibody and so on, which are the main components of nasopharyngeal carcinoma markers. It can significantly improve the early diagnosis rate of nasopharyngeal carcinoma and can be used for prognosis judgment at the same time. 2. EBV external markers: including gene methylation markers, peripheral blood protein markers, etc. Abnormalities in these indicators suggest that nasopharyngeal carcinoma has a higher risk of developing or has already occurred, and further imaging and other examinations are recommended. It is recommended to go to the hospital in time when there is a high expression level of nasopharyngeal cancer markers.
