microRNA in Thyroid Cancer

March 15, 2022 updated by: Hadassah Medical Organization

The Use of a microRNA Panel to Identify Thyroid Malignancy in FNA Leftover Cells and the Effect of These microRNAs on Target Genes.

Thyroid cancer is the most common endocrine malignancy and its incidence is rapidly increasing. Palpable thyroid nodules are very common, affecting up to 5% of the general population. Nevertheless, only 5% of the thyroid nodules harbor malignancy, hence the obvious need to accurately characterise these nodules. Ultrasound guided fine needle aspiration biopsy (FNAB) is the most important tool in assessing the nature of thyroid nodules, however, in up to 30% of the biopsies the results are indeterminate. In this proposal, the investigators hypothesize that leftover cells in the FNAB needle may be utilized for molecular analysis with an established microRNA panel and distinguish between malignant and benign lesions. Despite established studies on the diagnostic utility of microRNAs in thyroid nodules, the effect of microRNAs on specific target genes involved in thyroid cancer is poorly studied. In this proposal the investigators hypothesize that the microRNAs identified in our panel will affect intracellular pathways by regulating target genes that are involved in thyroid tumorigenesis. The investigators present preliminary data that confirms that microRNA panel may identify malignancy in thyroid nodules. In aim 1 the investigators will identify the expression profile of miRNAs in the different thyroid cancers. the investigators will statistically quantify the threshold of miRNA dysregulation for malignancy on a large number of tumor and benign samples. This will serve as matrix for defining malignancy on the FNAB samples. In aim 2 the investigators will establish a reliable reproducible method to extract RNA from cells left over in FNAB samples. the investigators' preliminary data support the feasibility of the method and it has not been described previously. This will be the first study that will compare cytology results and microRNA panel analysis on the very same FNAB cells. It will mimic the exact clinical scenario that such microRNA panel can be utilized in the future. Finally, in aim 3 the investigators will characterize the effect of microRNAs on target genes expression. the investigators will identify possible target genes from bioinformatics databases and will perform quantitative measurement of mRNA level of target gene by real time PCR and immunohistochemistry. These studies will hopefully support the utility of microRNAs as a diagnostic tool to accurately identify malignancy in thyroid FNAB leftover cells and point out possible target genes for future therapeutic approaches. This could impact many patients, as thyroid cancer is the 5th most common cancer in women, and the most rapidly growing malignancy in both men and women.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

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.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
September 12, 2013

Primary Completion (Actual)

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. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
December 30, 2015

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
