What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Adipose SVF cellBiological
adipose SVF cell transfer to the half of irradiated breast
Normal salineBiological
Normal saline inject to the half of irradiated breast
| Study group | Role | What they receive |
|---|---|---|
| Adipose SVF cell | Experimental | adipose SVF cell transfer to the half of irradiated breast Receives: Biological: Adipose SVF cell |
| Normal saline | Active comparator | Normal saline inject to the half of irradiated breast Receives: Biological: Normal saline |
What is being measured
The primary outcome is the main question the study is designed to answer.
The change in the breast skin thickness of the pre and post SVF graft from baseline at 12week after procedure
The efficacy is assessed by breast skin thickness measured by radiologist using breast ultrasonography
Measured: change in the breast skin thickness from baseline at 12 week

Questions about this trial
What is this clinical trial studying?
A study testing Adipose SVF cell and Normal saline in people with Breast Neoplasms and Skin Abnormalities, run by Seoul National University Hospital 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 4 inclusion and 7 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The record says: withdrawn, as of the sponsor's last update on 23 Oct 2020. 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The study was withdrawn before enrolling participants, so there are no results.
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?
The change in the breast skin thickness of the pre and post SVF graft from baseline at 12week after procedure (time frame: change in the breast skin thickness from baseline at 12 week). 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 23 Oct 2020; AzTrials last refreshed its copy on 7 Nov 2026.
