About this study

Official title: A Cluster Randomized Controlled Screening Trial for Nasopharyngeal Carcinoma in Southern China (CRCSTNPC Study)

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.

Read the detailed description

Nasopharyngeal carcinoma (NPC) has a high prevalence in southern China. Sihui and Zhongshan cities are located along the Pearl River in Guangdong Province, China, and are well known for a high incidence of NPC worldwide. During the last 20 years, Screening for NPC has been demonstrated to increase the early detection rate of NPC in endemic regions. It is well shown that the effect of Epstein-Barr virus (EBV) serological antibodies is elevated several years before NPC diagnosis; therefore, EBV antibodies have been considered screening markers for NPC. However, none of the studies have reported the impact of screening on NPC-specific mortality.

This study aims to launch a cluster-randomized screening trial with combined VCA/IgA and EBNA1/IgA measurement by ELISA as the primary screening method in these 2 cities to examine the impact of EBV serological screening on NPC-specific mortality. Residents aged 30-69 years in eight screening towns in the intervention group will be invited to EBV antibody tests-IgA antibodies to EBV VCA/IgA and EBV nuclear antigen-1 (EBNA1/IgA) by ELISA. The primary objective of this trial is to assess an estimate of the EBV serological antibody-based screening for NPC on NPC-specific in the populations with a high incidence of NPC

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Experimental: Screening with EBV VCA/EBNA1-IgA testingDiagnostic test

    Also called Diagnostic work-up using fiberoptic endoscopy examination and/or nasopharyngeal biopsies

    Participants in the screening towns will be offered screening tests. Those with high-risk scores will be referred to a diagnostic workup examination using fiberoptic endoscopy examination and nasopharyngeal biopsies if suspicious lesions is observed.

Study groupRoleWhat they receive
interventionExperimentalResidents aged 30-69 years in eight screening towns in the intervention group are invited to screening marker tests - IgA antibodies to EBV VCA/IgA and EBV nuclear antigen-1 (EBNA1/IgA) by ELISA. The trial will use two minimally acceptable false-positive rates (i.e., 10% and 3%) as the cutoffs to define "medium-risk" (seropositive, 0.65 ≤ score < 0.98) and "high-risk" participants (seropositive, score ≥ 0.98). After a blood test, participants whose EBV-based risk exceeds the predefined "high-risk" threshold (score ≥ 0.98) will be referred to endoscopy for clinical evaluation. Participants who are defined as "medium-risk" or "high-risk" (score ≥ 0.65) will be followed annually through blood testing and linkage to registers. The remaining participants (seronegative, score < 0.65) will be asked to return for a follow-up visit after five years.
Receives: Diagnostic Test: Experimental: Screening with EBV VCA/EBNA1-IgA testing
ControlNo interventionThe individuals aged 30-69 in the other eight towns will be included as controls, which is a comparable population that will not be screened for NPC.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mortality rate of NPC at 12 years by intervention group

    NPC mortality rate will be compared between screening group and control group at 12-year follow-up.

    Measured: December, 2019

Secondary outcomes (5)
  1. All-cause mortality at 12 years by intervention group

    All-cause mortality rate will be compared between screening group and control group at 12-year follow-up.

    Measured: December, 2019

  2. NPC incidence at 12 years by intervention group

    NPC incidence rate will be compared between screening group and control group at 12-year follow-up.

    Measured: December, 2019

  3. Stage distribution at diagnosis for NPC patients by intervention group

    Stage distribution will be compared between screening group and control group at 12-year follow-up.

    Measured: December, 2019

  4. NPC overall survival by cases from the two intervention groups

    Survival rate will be compared between screening group and control group at 12-year follow-up.

    Measured: December, 2019

  5. Cost-effectiveness

    Cost-effectiveness of this screening program will be calculated at 12-year follow-up.

    Measured: December, 2019
