This study is aimed to estimate the effectiveness of an Epstein-Barr virus (EBV) serology-based screening program to reduce nasopharyngeal carcinoma (NPC) mortality in a cluster randomized controlled trial in an NPC high-risk population. Sixteen towns in Sihui and Zhongshan Cities, China will be selected, with eight allocated to the screening group and eight to the control group. Cantonese residents aged 30-69 years with no history of NPC will be included. Residents in the screening towns will be invited to undergo serum EBV VCA/EBNA1 IgA antibody tests.
