About this study

Official title: Phase II Study of Hypofractionated Post Mastectomy Radiation With Two-Stage Expander/Implant Reconstruction

Hypofractionated radiotherapy could provide more convenient treatment and had similar toxicities.However,reports of hypofractionated radiotherapy with two-stage expander/implant reconstruction are rare,Some studies have shown that hypofractionated radiotherapy had similar toxicities to conventional fractionated radiotherapy in patients with breast reconstruction. So,investigators conducted a phase II study to observe the reconstruction failure in hypofractionated radiotherapy with two-stage expander/implant reconstruction.

Read the detailed description

Results from a phase III randomized controlled study in China showed that Postmastectomy hypofractionated radiotherapy was non-inferior to and had similar toxicities to conventional fractionated radiotherapy in patients with high-risk breast cancer.However,reports of hypofractionated radiotherapy with two-stage expander/implant reconstruction are rare. Literatures report that reconstruction failure is a well-known complication of radiation therapy in breast cancer patients with reconstruction. Results may vary based on RT timing and technique. Some studies have shown that hypofractionated radiotherapy had similar reconstruction failure to conventional fractionated radiotherapy in patients with breast reconstruction. So,investigators conducted a phase II study to observe the reconstruction failure in hypofractionated radiotherapy with two-stage expander/implant reconstruction.

What is being measured

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

  1. reconstruction failure

    the 1-year rate of implant removal due to serious complications (such as infection, hematoma, seromatas, prosthesis exposure, prosthesis rupture, envelope contracture, severe breast deformity, etc.)

    Measured: 12 months after the reconstructive surgery

Secondary outcomes (1)
  1. cosmetic result

    Digital photographs will be taken of each patient to facilitate thorough assessment of breast symmetry, cleavage and donor site scarring. Overall satisfaction is scored on a five-point Likert scale (1 = very unhappy, 5 = very happy).

    Measured: 12 months after the reconstructive surgery

Questions about this trial

What is this clinical trial studying?

A study testing hypofractionated radiotherapy in people with Breast Carcinoma, run by Chinese Academy of Medical Sciences 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 6 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: status not confirmed, as of the sponsor's last update on 16 Sep 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 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.

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?

Contact Ning Li, MD (010-8778-8221, lining@cicams.ac.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

reconstruction failure (time frame: 12 months after the reconstructive surgery). 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 NCT05045287, which also lists 4 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 16 Sep 2021.
