About this study
Official title: The Prevalence, Risk Factors and Optimal Biopsy Protocol of Barrett's Esophagus in Taiwan - A Prospective Randomized Study
Detections of goblet cells and dysplasia are crucial for diagnosis and determining the surveillance program of Barrett's esophagus (BE). However, the optimal biopsy numbers and their yield rates of intestinal metaplasia (IM) and dysplasia are still uncertain, especially in Asia. The aim of this study was to determine the optimal biopsy protocol of BE.
Read the detailed description
Barrett's esophagus (BE) is premalignant lesion for esophageal adenocarcinoma (EAC) and defined as the distal esophageal squamous epithelium replaced by columnar epithelium with histologic confirmation of intestinal metaplasia (IM). The accurate prevalence of BE is difficult to assess because part of people with BE are asymptomatic. However, the prevalence of gastroesophageal reflux disease (GERD) which is the main factor associated with BE has increased almost 50% during the last 20 years. Meanwhile, the general population prevalence of BE is estimated to increase to 3-10% in Western countries. The systematic review and meta-analysis also reported an upward trend in prevalence of BE in Asian countries. BE is an important heathy issue to investigate in either Western or Asian countries.
The annual rate of developing esophageal adenocarcinoma is around 0.2% to 0.5% in patients with BE. However, the annual adenocarcinoma progression risk is different between the non-dysplastic Barrett's esophagus (NDBE), BE with low-grade dysplasia (LGD) and high-grade dysplasia (HGD). The annual incidence of esophageal adenocarcinoma is 0.33%, 0.54% and 6.58% in patients with NDBE, BE with LGD and HGD, respectively. Among patients with NDBE, patients with short segment BE (SSBE) have the lower rate of progression to EAC than those who with long segment BE (LSBE) (0.07% vs 0.25%). Therefore, endoscopic surveillance of patients with BE is recommended by clinical practice guideline.
Detections of goblet cells and dysplasia are crucial for diagnosis and determining the surveillance program of BE. According to the Seattle protocol which has been widely recommended by clinical practice guidelines, biopsy specimens should be obtained every one cm to two cm interval across the four quadrants of the columnar epithelium of esophagus. Fewer endoscopists adhered to this protocol in clinical practice because of its laboriousness and time consumption. Most of patients with BE were categorized as SSBE and SSBE seems to be more prevalent in Asian populations. As the report of previous study which reviewed the general prevalence of BE in Western and Asian general populations, the ratio of SSBE to LSBE was ranging from 1.8 to 17.4 in the Western countries and 1.7 to 103 in the Asian countries. It's more difficult to adhere to the protocol in patients with SSBE.
However, the optimal biopsy numbers and their yield rates of IM and dysplasia are still uncertain, especially in Asia. The investigators aimed to assess the biopsy numbers and yield rates of IM and dysplasia in patients with columnar-lined esophagus (CLE) to determine the optimal biopsy protocol.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Detections of goblet cells and dysplasia are crucial for diagnosis and determining the surveillance program of Barrett's esophagus (BE). However, the optimal biopsy numbers and their yield rates of intestinal metaplasia (IM) and dysplasia are still uncertain, especially in Asia. The aim of this study was to determine the optimal biopsy protocol of BE.

Questions about this trial
What is this clinical trial studying?
A study testing One biopsy, Three biopsy and Seattle protocol in people with Barrett's Esophagus and Intestinal Metaplasia, run by E-DA Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 11 May 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Ying-Nan Tsai, M.D (886-7-6150011 ext. 252294, littlepig9933@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05818072, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
