Screening af nasopharyngealt karcinom med EBV-associerede biomarkører i Zhongshan City
Søger efter tidlig påvisning af biomarkører for nasopharyngealt karcinom i Zhongshan City
The study includes two cohorts: (1) a serological screening cohort; (2) a serological and EBV DNA screening cohort. All participants will be tested for EBNA1-IgA, VCA-IgA, BNLF2b total antibodies (P85-Ab), with additional plasma EBV DNA testing in the latter cohort. Screening positive participants will be followed up annually.
All subjects will also be followed by record linkage to Cancer Register and Population Register.

Detaljeret beskrivelse
Sample selection
- Select communities of 20,000 to 40,000 populations in Zhongshan City and Wuzhou city as the investigators' fields.
Participants recruitment
- Subjects voluntarily attend this screening study Informed consent - Informed consent forms will be collected at the recruitment. Questionnaires.
- Face-to-face interviews are conducted by well-trained investigators.
Tests and follow up
- At initial screening, all participants in both cohorts will be tested for EBV associated biomarkers, including EBNA1-IgA, VCA-IgA, P85-Ab et al. And in the serological and EBV DNA screening cohort, EBV-DNA will be tested. Consecutive EBV DNA positivity is defined as positive plasma EBV DNA results at both baseline and repeat testing approximately 4 weeks later. Based on EBNA1-IgA, VCA-IgA, participants will be stratified into high, moderate and low risk. Screening positive include P85-Ab positive, high or moderate risk of NPC or consecutive EBV DNA positive. The rest will be screening negative.
- During the initial screening and following up, people with high risk or P85-Ab positive or consecutive EBV DNA positive will refer to the diagnostic workup for NPC. Briefly, fiberoptic endoscopy and pathological biopsy will be performed by otorhinolaryngologists.
- Screening positive people not diagnosed as nasopharyngeal carcinoma in the first year will be followed up annually.
- EBV DNA single positive people will refer to the diagnostic workup for NPC in the third year of follow up.
- The rest of the blood samples will be stored at the biobank of Zhongshan People's Hospital for further research.
- All subjects will also be followed by record linkage to Cancer Register and Population Register.
