Observation on the Efficacy of Radiofrequency Ablation for Patients With Moderate to Severe Gastric Atrophy With Enterosis With or Without Atrophy of Intraepithelial Neoplasia: An Observational Study

December 26, 2024 updated by: Xiuli Zuo

The aim of this observational study was to understand the effect of radiofrequency ablation on subjects with moderate to severe gastric atrophy with enterocolitis with or without low-grade intraepithelial neoplasia who underwent radiofrequency ablation. The main question it aims to answer is:

Does radiofrequency ablation therapy reduce gastric mucosal atrophy and enterosis in subjects with moderate to severe gastric atrophy with enterosis with or without low-grade intraepithelial neoplasia?

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Not yet recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Outpatient or inpatient collection of study participants was done by recruiting participants who met the inclusion criteria and did not meet the exclusion criteria and signed an informed consent form. Study participants were identified for enrollment and a case report form was completed. The basic demographic information of the study participants was recorded, along with the results of existing routine laboratory tests, and symptom-related clinical characteristics. Gastroenterology reports and pathology reports were retained for enrolled study participants to score and grade each study participant specifically, and all study participants were treated with radiofrequency ablation after enrollment. Follow-up gastroscopy was performed on study participants 3 months after treatment, adverse reactions during the two gastroscopies were recorded and case report forms were supplemented, gastroscopy reports and pathology reports of study participants were retained again, and gastroscopy reports and pathology reports of study participants were evaluated, and data on changes were summarized. Follow-up gastroscopy was performed on study participants 3 months after treatment, adverse reactions during the two gastroscopies of study participants were recorded and additional case report forms were completed, gastroscopy reports and pathology reports of study participants were again retained and gastroscopy reports and pathology reports of study participants were evaluated, and data on changes were summarized. Study participants who failed treatment but did not develop new intraepithelial neoplasia summarized the reasons for their failure and were re-treated with radiofrequency ablation 3 months later, and this was repeated until treatment was successful; study participants who developed new low-grade intraepithelial neoplasia were treated with radiofrequency ablation at post-treatment follow-up, and this was repeated until treatment was successful; and study participants who developed new intermediate- and high-grade intraepithelial neoplasia were treated with ESD at post-treatment follow-up, and this was repeated until treatment was successful. All data were summarized at the end of enrollment for all study participants and statistically analyzed.

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The study recruited study participants with moderate-to-severe gastric atrophy with enterocolitis with or without low-grade intraepithelial neoplasia detected in the outpatient or inpatient setting; upon entry into the study, study participants were required to meet the inclusion criteria and not to meet the exclusion criteria, and to sign an informed consent form

Description

Inclusion Criteria:

  • Age 18-70 years old, male or female.
  • Patients who had undergone gastroscopy within 3 months prior to inclusion, and whose histologic diagnosis of chronic gastritis was histologically atrophic enterocolitis graded at moderate-to-severe with or without low-grade intraepithelial neoplasia.
  • Patients who had undergone gastroscopy within 3 months prior to inclusion, and whose OLGA (atrophic grading and staging criteria for chronic gastritis) or OLGIM (enteric grading and staging criteria for chronic gastritis) staging criteria had reached moderately severe.
  • Helicobacter pylori negative.

Exclusion Criteria:

  • Pregnant or lactating women.
  • Previous history of malignant tumors of the digestive tract or history of gastrointestinal surgery.
  • Malignant tumors of other organs, coagulation disorders, cardiopulmonary insufficiency, hepatic and renal insufficiency, etc.
  • Those who are unable or unwilling to sign the informed consent form.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Eradication and remission rates after radiofrequency ablation therapy in study participants with moderate to severe gastric atrophic enterosis with or without low-grade intraepithelial neoplasia
Time Frame: 3 Months After Participants Underwent Radiofrequency Ablation
3 Months After Participants Underwent Radiofrequency Ablation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures.
