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

The management of multiple endocrine neoplasia type 1 (MEN1-1)-related pancreatic neuroendocrine tumors (pNETs) remains controversial. In general, surgical resection is currently the first-line therapy for MEN1-1-related pNETs. However, the surgical resection of pNETs is conditional for specific patients, and the incidence of postoperative adverse events is still high. Recently, several studies have demonstrated that endoscopic ultrasonography (EUS)-guided fine-needle injection (EUS-FNI) with ethanol or lauromacrogol may provide an alternative to surgical resection of pNETs. Nevertheless, their sample size was relatively small and conclusions were drawn based on short-term results. Therefore, a multicenter prospective study is being performed to further access the efficacy and safety of EUS-FNI for MEN1-1-related pNETs.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Patients with MEN1-1-related pNETs are evaluated by histopathology and genetic testing.
  2. Patients who refuse surgery.
  3. Patients who have given their fully informed consent.

Exclusion Criteria:

  1. Patients who are not suitable for the endoscopic procedure.

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: MEN1-1-related pNETs
The patients with MEN1-1-related pNETs will undergo EUS-FNI with ethanol or lauromacrogol
Procedure: EUS-guided fine-needle injection
Diagnostic evaluation for suspected MEN1-1-related pNETs is conducted by cytology or immunohistochemistry and genetic testing. EUS-FNA is performed to obtain samples. After puncturing with the needle, ethanol/ lauromacrogol under the guidance of EUS was injected into the tumor The volume of ethanol/ lauromacrogol is administrated based on the tumor size.

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: Within 7 days of the last ablation and every 6 months up to 24 months
Changes in the lowest blood glucose levels between baseline and last treatment and each study visit

Changes of insulin level
Time Frame: Within 7 days of the last ablation and every 6 months up to 24 months
hanges in the insulin levels between baseline and last treatment and each study visit
