Study Description
Brief Summary:
To evaluate the efficacy of endoscopy screening on esophageal cancer (EC) and determine the most cost-effective strategy of endoscopy screening in high risk population of China, 668 villages of Hua county, a high risk area of esophageal cancer, were randomized into screening arm and control arm in a ratio of 1:1 and the total sample size is over 30,000 (~16,000 per group). Participants in the screening arm will accept standard endoscopy examination to detect early esophageal cancer and no screening were designed in control arm. The incidence of advanced EC and EC-specific mortality will be compared within the two groups to test the hypothesis that endoscopy screening would detect early stage cancer and the incidence of advanced stage EC and EC-specific mortality will be lower than control group. Cost-effectiveness analysis will also be conducted to find the most cost-effective strategy of endoscopy screening in rural China.

Arms and Interventions

Arm Intervention/treatment
No Intervention: Control Arm
Participants in this arm will not accept the endoscopy screening and only baseline and follow-up interview will be conducted in this arm.
Experimental: Screening Arm
Participants in this arm will accept a baseline endoscopy screening and questionnaire investigation and follow-up interview. If applicable, all participants in this arm will accept a second endoscopy screening in the 5th year of the study.
Procedure: Endoscopy Screening
  1. Upper G.I. endoscopy examination with Lugols Iodine in esophagus
  2. Biopsy at the visually abnormal sites
  3. Pathologic examination of all biopsy tissue specimens
  4. Advise of regular re-examination will be given to participants who are diagnosed of moderate and severe dysplasia.
  5. Advises of endoscopic or surgical treatment will be given to participants who are diagnosed of early upper G.I. carcinomas.

Outcome Measures

Primary Outcome Measures :
  1. Esophageal cancer specific mortality [ Time Frame: 5-10 years ]
  2. Cost for saving 1 quality-adjusted life year (QALY) [ Time Frame: 5-10 years ]

Secondary Outcome Measures :
  1. Cumulative incidence of advanced esophageal cancer [ Time Frame: 5-10 years ]
  2. Change of life quality due to early diagnosis and treatment [ Time Frame: 5-10 years ]
