Recruit Status: Recruiting
Study Type: Observational
Official Title: Metabolomics and Genetic Diagnosing Pancreatic Neuroendocrine Tumors in Multiple Endocrine Neoplasia Type 1 Patients
Brief Summary:
Objectives:
The aim of the present study is to assess the significance of metabolomics and genetics in diagnosing and survival evaluation for pNET in the periodic follow-up of MEN1 patients.
Aim 1: To evaluate the relationship of serum global metabolic profiles with subsequent development of aggressive PNET and evaluate patients survival in a nested case-control study of MEN1 patients who have developed aggressive PNETs (cases) and MEN1 patients who have developed non-aggressive PNETs (controls).
Aim 2: Validate the top serum metabolites identified from Aim 1 in MEN1 patients who have developed aggressive PNETs and MEN1 patients who have developed non-aggressive PNETs, using a targeted metabolomics approach.
Aim 3: Prospectively identify the potential miRNA biomarkers of serum with miRNA sequencing in MEN1 patients who have developed aggressive PNETs (cases) and MEN1 patients who have developed non-aggressive PNETs (controls).
Aim 4: Validate the potential miRNA biomarkers identified from Aim 1 in MEN1 patients who have developed aggressive PNETs and in MEN1 patients who have developed non-aggressive PNETs, using a targeted qRT-PCR approach (in serums), as well as to see the relationship of potential miRNA biomarkers with patients survival.

Current Primary Outcome: Relationship of Serum Global Metabolic Profiles with Subsequent Development of Aggressive PNET [ Time Frame: 10 years ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Prediction of Occurrence of Aggressive PNET among MEN1 Patients by Examining Patterns of Serum Metabolic Biomarkers [ Time Frame: 10 years ]Advanced metabolomics technology used to demonstrate that various patterns of serum metabolic biomarkers can predict the occurrence of aggressive PNET among MEN1 patients.
- Prospectively Identify Potential miRNA Biomarkers of Serum with miRNA Sequencing in MEN1 Patients Who Have Developed Aggressive PNETs (Cases) and MEN1 Patients Who Have Developed Non-Aggressive PNETs (Controls) [ Time Frame: 10 years ]The levels of miRNA in each group defined as mean ±SD. One-way ANOVA used to identify possible associations between miRNA concentrations and clinicopathological features of aggressive patients.
Original Secondary Outcome: Same as current
