UNN-RADS Scale for Diagnosing Lymph Node Metastasis in Patients With History of Thyroid Cancer

November 6, 2023 updated by: Hilda Elizabeth Macías Cervantes, Instituto Mexicano del Seguro Social

Validation of The Ultrasound Neck Node Reporting and Data System (UNN-RADS) Scale for Diagnosing Lymph Node Metastasis in Patients With History of Thyroid Cancer

In 2020, Sarda-Inman et al., developed the Ultrasound Neck Node Reporting and Data System (UNN-RADS) scale that allows decision-making about when it is appropriate to perform FNA of a cervical lymph node, evaluating seven ultrasonographic descriptors (shape, margins, echogenicity, echogenicity of the hilum, vascularity and the presence/absence of calcifications, and cystic degeneration), features that have been associated with metastatic lymph nodes, with scores ranging from 0 to 3 points, which allows categorize into 5 different risk groups. Thus, the objective of this study is to evaluate the ultrasound characteristics of metastatic LN in patients undergoing TC follow-up and to validate the UNN-RADS scale for the diagnosis of LN Metastasis in Patients with a history of TC.

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.

Detailed Description

This study enrolled consecutive patients in follow-up for differentiated thyroid cancer (DTC) history who underwent US-guided fine needle aspiration (FNA) of the LNs for suspicious metastatic cervical lymph nodes. Patients were included if they 1) had previous history of DTC, 2) both sexes with age over 18 years old, and 3) underwent FNA of the LNs for any suspected features corresponding with at least UNN-RADS 1. Patients were excluded if they underwent FNA of the LNs for persistent or recurrent disease after surgery for thyroid cancer, had previous bilateral cervical lymph node dissection as initial treatment, or the FNA results were not concluded.

UNN-RADS 1 y 2 and UNN-RADS 3, 4 and 5 were grouped for analysis purpose. Diagnostic performance of UNN-RADS scale were assessed in terms of sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), positive likelihood ratios (+LR), negative likelihood ratios (-LR) and accuracy, as well as with a receiver operating characteristic (ROC) curve.

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.

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
Measure Description
Time Frame
metastatic lymph node
Time Frame: All biopsy samples were sent to the pathology department of the unit, where final results were obtained in approximately 2-3 weeks.
Fine needle aspiration biopsy (FNA) results were the gold standard (metastatic or benign).
All biopsy samples were sent to the pathology department of the unit, where final results were obtained in approximately 2-3 weeks.

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.

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.
