About this study

The incidence of breast reconstruction failure after conventional photon radiotherapy for breast cancer is about 18.7%. At present, there is limited data on proton radiotherapy for post operative breast cancer with implantation reconstruction. Proton radiotherapy for breast cancer can significantly reduce the radiation dose of the ipsilateral heart and lung, thereby reducing the incidence of cardiac events and radiation pneumonia. This study is aimed at the study of adjuvant hypofractionated intensity-modulated proton radiotherapy for post operative breast cancer with implantation reconstruction. It can provide an ideal treatment option for such patients to effectively protect the heart and lungs without increasing the failure rate of breast reconstruction after adjuvant radiotherapy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. the failure rate of breast reconstruction after hypofractionated proton radiotherapy

    Reoperation

    Measured: within 2 years after hypofractionated proton radiotherapy

Secondary outcomes (2)
  1. Acute and late toxicities

    Treatment related toxicity assessed by CTCAE v4.03

    Measured: within 5 years after radiotherapy

  2. Tumor local control rate, overall survival rate and progression free survival rate

    The Ipsilateral breast and regional lymph nodes recurrence, death and progression

    Measured: within 5 years after radiotherapy

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing adjuvant hypofractionated intensity-modulated proton radiotherapy in people with Breast Cancer, run by Shanghai Proton and Heavy Ion Center at 1 site in China.

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 8 inclusion and 8 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: looking for participants now, as of the sponsor's last update on 20 Jan 2023. 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 China. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the failure rate of breast reconstruction after hypofractionated proton radiotherapy (time frame: within 2 years after hypofractionated proton radiotherapy). 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 20 Jan 2023.
