About this study

Official title: Evaluation of a New Technique to Fill the Defect Generated After Conservative Surgery in Breast Cancer: Randomized Clinical Trial

The placement of a small silicone prosthesis in the partial defects generated by conservative breast cancer surgery improves the aesthetic result, compared to the usual surgical technique, in a safe and reproducible way and compatible with adjuvant treatments. It could also potentially improve the quality of life of patients

Read the detailed description

Conservative surgery in breast cancer is performed more than 50% of cases, however, aesthetic results are suboptimal, because reconstructive techniques are performed in less than 5% of them. Objective: To demonstrate that the placement of a silicone prosthesis in partial defects generated by breast cancer conservative surgery improves the aesthetic result, compared to the usual surgical technique, safely, reproducibly and compatible with adjuvant treatments.

Methodology: Prospective randomized clinical trial, controlled with blind evaluator. Inclusion criteria: Women with breast cancer candidates for conservative surgery. Intervention: In the cases the study technique will be carried out consisting in the filling of the defect with a silicone prosthesis of size adjusted to it (2-4cm). Controls: usual surgical procedure. Main result variable: aesthetic results (visual analog scale) according to the patient, surgeon and blind external evaluator. Secondary variables: surgical complications, local complications derived from adjuvant treatments, rate of local recurrence, rate of reintervention due to affected margins, behavior in mammographic follow-up, professional satisfaction and impact on quality of life.

Study groupRoleWhat they receive
Group intervention: Silicone prothesisExperimentalBreast cancer conservative surgery will be performed by removing the tumor according to the usual technique and then the defect generated will be filled with a silicone prosthesis of the same size. Said prosthesis will be covered with fat and subcutaneous cellular tissue and then the skin will be closed.
Receives: Device: Silicone prosthesis
Group control: Usual surgical techniqueActive comparatorBreast cancer conservative surgery will be performed according to the usual surgical technique, that is, removing the tumor and covering the defect by mobilizing the breast tissue and then closing the skin.

What is being measured

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

  1. Aesthetic result

    Aesthetic result of the new technique by applying a visual analog scale for measuring patient satisfaction.

    Scale ranges: minimum score: 0 (no satisfaction - worse outcome), maximum score: 10 (total satisfaction - better outcome)

    Measured: 4 weeks

Secondary outcomes (1)
  1. Surgical complications

    Incidence of surgical complications.

    Measured: 4 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Silicone prosthesis and Usual practice in people with Breast Conserving Surgery, run by Fundació Institut de Recerca de l'Hospital de la Santa Creu i Sant Pau at 1 site in Spain.

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 1 inclusion and 6 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 6 Apr 2022. 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 Spain. 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 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?

Aesthetic result (time frame: 4 weeks). 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 6 Apr 2022.
