Brief Summary:
The purpose of this study is to determine if the screening of nasopharyngeal carcinoma using plasma Epstein-Barr virus DNA analysis would result in the down-staging of the NPC cases in asymptomatic individuals.

Condition or disease
Nasopharyngeal Carcinoma

Detailed Description:

Epstein-Barr virus (EBV) infection is an important etiological factor for nasopharyngeal carcinoma (NPC). In a pilot study, we have shown that the analysis of Epstein-Barr virus (EBV) DNA in blood can detect early and asymptomatic NPC. However, it is unlcear if NPC screening can improve the prognosis of the screened NPC subjects.

20,000 male subjects aged from 40 to 62 will be recruited because the incidence of NPC is higher in this target group. Twenty millilitres of venous blood will be collected from each subject at enrolment for plasma EBV DNA analysis.

Subjects who have initial positive results for plasma EBV DNA will have another testing at approximately 4 weeks. Subjects who have persistently positive results for the two plasma EBV DNA analyses will be investigated using nasal endoscopic examination and MRI of the nasopharynx.

After the initial screening, all participants will be phone interviewed yearly to update their cancer status.

Primary Outcome Measures :
  1. Stage distribution of nasopharyngeal carcinoma at the time of diagnosis [ Time Frame: 3 years ]
    All the participants will be subjected to the screening of nasopharyngeal carcinoma (NPC) at the time of recruitment using plasma EBV DNA analysis. Subjects with positive results will be investigated using endoscopic examination and MRI. If the subject is confirmed of having NPC, the stage of the disease would be recorded.

Secondary Outcome Measures :
  1. Incidence of nasopharyngeal carcinoma in screened negative group [ Time Frame: 5 years ]
    Participants who are screened negative will be followed up yearly for 5 years after the screening. The incidence of NPC will be recorded.

Biospecimen Retention:   Samples With DNA
Plasma samples are retended for future study to evaluate the accuracy of sequencing-based biomarkers
