adjuvant ultra-hypofractionated radiotherapyRadiation
adjuvant ultra-hypofractionated radiotherapy for the treatment of early and locally advanced breast cancer
| Study group | Role | What they receive |
|---|---|---|
| Single Arm Ultra-hypofractionated | Experimental | 5 fractions of 5.7 Gy every other day in the breast or chest wall region, with or without the inclusion of regional lymph node drainage chains Receives: Radiation: adjuvant ultra-hypofractionated radiotherapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Acute toxicity
Acute skin toxicity was evaluated the criteria followed the Standard Common Terminology Criteria for Adverse Events - CTCAE v 5.0
Measured: Events of radiotherapy up to 3 months
Late toxicity
Delayed skin and subcutaneous toxicities were evaluated according to the Radiation Therapy Oncology Group (RTOG) classification.
Measured: Events after 3 months of radiotherapy completion
Secondary outcomes (5)
Locoregional free survival
from the date of initiation of treatment until the date of recurrence or progression of locoregional disease evidence
Measured: 3 years
Distant free survival
from the date of initiation of treatment until the date of progression of distant disease evidence
Measured: 3 years
Overall survival
defined from the date of initiation of treatment until the patient's death
Measured: 3 years
Cosmesis change
was assessed using the Harvard/NSABP/RTOG scale. The Harvard/NSABP/RTOG scale score is a 4-point breast cosmetic scale, which was assessed by clinicians at baseline (after surgery) and two additional times during follow-up.
- Excellent: When compared to the untreated breast, there is no difference or minimal difference in the size or shape of the treated breast. The breast texture is the same or slightly different. There may be thickening, scar tissue, or fluid buildup in the breast, but not enough to change the appearance.
- Good: There is a slight difference in the size or shape of the treated breast compared to the untreated breast or compared to the original appearance of the treated breast. There may be a slight reddening or darkening of the breast. Thickening or scar tissue inside the breast causes only a slight change in shape or size.
- Fair: Obvious difference in the size and shape of the treated breast. This change involves a quarter or less of the breast. There may be
Measured: week 10 and week 26 after the end of the treatment
QOL (Quality of Life) changes
was assessed using the scales proposed by the EORTC (European Organization for Research and Treatment of Cancer). The EORTC QOQ-C30 and EORTC QLQ-BR-23 scales.
All of the scales and single-item measures range in score from 0 to 100. A high scale score represents a higher response level. Thus a high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status / QoL represents a high QoL, but a high score for a symptom scale / item represents a high level of symptomatology / problems.
Measured: 3 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing adjuvant ultra-hypofractionated radiotherapy in people with Breast Cancer Female, run by Prevent Senior Institute at 1 site in Brazil.
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 5 inclusion and 5 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 4 Apr 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 Brazil. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
Acute toxicity (time frame: Events of radiotherapy up to 3 months). The study lists 2 primary outcomes in all. 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 NCT05850637, which also lists 80 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 4 Apr 2024.
