About this study

In this study, the investigators look at the genetic expressional alteration which influenced on the early lateral neck node metastasis in thyroid papillary microcarcinoma.

Read the detailed description

Papillary thyroid carcinomas (PTCs) measuring 1.0 cm or less in diameter were defined as papillary thyroid microcarcinomas (PTMCs) by the World Health Organization (WHO), emphasizing on their benign behavior, probably of little clinical significance, which do not affect patients' survival. However, some reported that PTMCs may have aggressive behavior, can cause locoregional recurrences, cervical lymph node metastases, and even distant metastases. But till now, the characteristics of PTMCs with early lateral neck node metastasis were only reviewed and described by the clinicopathological parameters, and no analysis of PTMCs by the gene level is available. In these study, we investigate the genetic expressional alteration which influenced on the early lateral neck node metastasis in thyroid papillary microcarcinoma.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. mRNA expression pattern by microarray analysis

    mRNA expression differences between papillary thyroid microcarcinoma without lateral neck node metastasis and the one with lateral neck node metastasis. (The outcome will be measured within 24-hour after surgical removement using papillary thyroid microcarcinoma tissue.)

    Measured: 24-hour after surgical removement

Questions about this trial

What is this clinical trial studying?

An observational study of Papillary Thyroid Microcarcinoma, run by Yonsei University at 1 site in South Korea.

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 3 inclusion and 3 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: finished, as of the sponsor's last update on 28 Mar 2019. 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 South Korea. 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. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

mRNA expression pattern by microarray analysis (time frame: 24-hour after surgical removement). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01384669, which also lists 20 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Mar 2019; AzTrials last refreshed its copy on 27 Oct 2026.
