About this study

Official title: Hypofractionated Versus Standard Fractionated Whole Breast Irradiation to Node-negative Breast Cancer Patients: a Randomized Phase III Trial, CIRRO (The Lundbeck Foundation Center for International Research in Radiation Oncology)

The purpose of this study is to investigate the difference in late radiation morbidity between hypofractionated and standard fractionated breast irradiation given to women operated with breast conservation for early breast cancer.

Read the detailed description

The randomization is between 50 Gy/25 fractions, 2.0 Gy per fraction, 5 fractions weekly, and 40 Gy/15 fractions, 2.67 Gy per fraction, 5 fractions weekly. The primary endpoint is late radiation morbidity; secondly, we want to investigate the frequency of local recurrences, and try to establish a genetic risk profile for development of late radiation morbidity.

The hypothesis is that women operated with breast conserving strategy for early breast cancer can be offered moderately hypofractionated radiotherapy without developing more late radiation morbidity compared to standard fractionated radiotherapy.

Being tested
standard fractionated radiotherapy, hypofractionated radiotherapy
Medical subject headings
Breast Neoplasms, Breast Carcinoma In Situ

Questions about this trial

What is this clinical trial studying?

A study testing standard fractionated radiotherapy and hypofractionated radiotherapy in people with Breast Cancer and Carcinoma in Situ of the Breast, run by Danish Breast Cancer Cooperative Group at 1 site in Denmark.

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 4 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: status not confirmed, as of the sponsor's last update on 24 Aug 2021. 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 Denmark. 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?

Results are not available in the source record.

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?

Grade 2 or 3 fibrosis 3 years after radiotherapy (time frame: 3 years). 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 NCT00909818, which also lists 1 linked publication.

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 Aug 2021.
