Summary

All participants will be tested for EBV-related biomarkers, including EBNA1-IgA, VCA-IgA, and BNLF2b total antibody (P85-Ab), and participants with high serologic risk will be selected based on serologic test results, and dual-energy CT will be performed first for high-risk screening subjects, and dual-energy CT will be performed first for the high-risk group to record dual-energy CT examinations of those suspected of nasopharyngeal carcinoma, and then endoscopy was performed on the high-risk group to record those suspected of nasopharyngeal carcinoma under endoscopy, and finally biopsies were taken for positive lesion sites indicated by dual-energy CT and suspicious lesion sites found by endoscopy to clarify the diagnosis.
