About this study

Official title: Sonography for COVID-19 Vaccines Related Reactive Lymphadenopathy: A Retrospective Study

This study aimed to provide vast clinical information to facilitate breast sonographic examination for participants who underwent recent SARS-CoV-2 vaccination.

Among different SARS-CoV-2 vaccines in the Asian Taiwanese population, reactive axillary lymphadenopathy was investigated through breast sonographic findings and clinical data analysis. The sample included participants with recent vaccinations by different brands approved in Taiwan.

Read the detailed description

Study Design and Sample The retrospective study included female patients who underwent breast sonography in the radiology department of Chi Mei Medical Center between July 2021 and March 2022. The patients' breast cancer history and COVID-19 vaccination history were collected and analyzed.

Analysis of Breast Sonography Lymphadenopathy is defined as an enlarged lymph node with cortical thickening >3 mm, either concentric or eccentric, with or without effacement of fatty hilum, or in-creased non-hilar vascularity on color or power Doppler. The positive axillary lymph node findings were correlated by confirming a link to SARS-CoV-2 vaccination history within 90 days in the ipsilateral arm.

Statistical Analysis All statistical analyses were performed using the R Stats package. Descriptive summaries were reported as mean ± standard deviation for continuous variables and percentages for categorical variables. For non-parametric variables, median with interquartile range and Mann-Whitney U test were used. Statistical significance was set at a p-value <0.05.

Being tested
the AstraZeneca ChAdOx1 (AZ) vaccine, Moderna mRNA-1273 (Moderna) vaccine, and Pfizer-BioNTech BNT162b2 (BNT) vaccine.
Keywords

Questions about this trial

What is this clinical trial studying?

An observational study of Reactive Axillary Lymphadenopathy for SARS-CoV-2 Vaccines in the Asian Taiwanese Population, run by Chimei Medical Center at 1 site in Taiwan.

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 1 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 24 May 2024. 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 Taiwan. 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?

Presentation of axillary lymphadenopathy in sonographic examination (time frame: through study completion, an average of 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 24 May 2024.
