An interventional study of Result masking in Early Detection of Cancer, sponsored by Yanqing Li. Status unknown at 1 site in China. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-08-28.
Sponsored by Yanqing Li · Not applicable, Interventional, and Screening
Despite improvements in a range of chemo, radio and surgical therapies, the overall survival at 5 years from gastrointestinal cancer remains poor. Endoscopic early diagnosis is a key strategy to improve survival but the detection rate of early cancer varies among different countries. Risk factor questionnaire result is easy to be obtained and may be of great help for improving the detection rate. The aim of this research is to validate a risk factor questionnaire to help predict gastrointestinal cancer therefore allowing earlier diagnosis and higher detection rate.
779 studies on the registry are indexed under Gastrointestinal Neoplasms; 231 are open to participants now.
This study's planned enrollment of 34,906 is above the median of 60 across 569 interventional studies indexed under Gastrointestinal Neoplasms.

Exclusion Criteria:
During the application stage of endoscopy, the patients are required to complete a RFQ according to their own situations. The RFQs will soon uploaded to the core server of the quality control system and be analysed automatically immediately after finish. The results are sorted into four types including "N/A", "High-risk for esophageal cancer", "High-risk for gastric cancer" and "High-risk for colorectal cancer", which will be shown during the endoscopy of the specific person. The endoscopies are carried out by experienced endoscopists. All of the data of the endoscopy itself are collected and recorded in the quality control system. The RFQ results of this group are not known (deliberately showing "N/A") by the endoscopists before and during the endoscopy.

Other: Result masking
The quality control system randomly shows the RFQ result to the endoscopists and keep 50% of the RFQ results are not known (deliberately showing "N/A") by the endoscopists before and during the endoscopy.
Rate change
The endoscopic detection rate change of precancerous lesions and early GI cancer with the help of self-rating RFQ for the prediction of GI cancer.
Time frame: up to 24 months
