Trial summary

Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death in females in the world. Neoadjuvant chemotherapy (NAC) is increasingly used in patients with operable breast cancer to enhance the likelihood of breast conservation. Read more about this study

About this study

Official title: Prospective Multicenter Pilot Study to Evaluate the Accuracy of Percutaneous Biopsy by Vacuum-assisted Biopsy (VAB) to Assess Pathological Complete Response in Patients With Clinical and Radiological Complete Response After Neoadjuvant Chemotherapy (NeoVAB)

Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death in females in the world. Neoadjuvant chemotherapy (NAC) is increasingly used in patients with operable breast cancer to enhance the likelihood of breast conservation. New generation of treatments or combinations lead to a high rate of pathological complete responses (pCR) in patients with human epidermal growth factor receptor 2 positive (HER2) and triple negative tumours. Safe omission of surgery in patients who receive NAC and achieve radiologic complete response depends on the ability to accurately estimate pCR preoperatively.

If pathological complete response after NAC could be accurately assessed by VAB, surgery could be avoided. In the context of new treatments or combinations with an increased pCR rate, this new strategy could induce major changes in clinical practice, leading to breast surgery de-escalation.

Read the detailed description

A total of 66 patients will be submitted to percutaneous vacuum-assisted biopsy (VAB), followed by breast surgery. The primary endpoint of the study is the false negative rate of VAB procedure. This rate will be calculated by comparing the detection of invasive or in situ carcinoma on surgical specimen versus VAB samples. The secondary endpoints of the study are feasibility, VAB procedure technical complications and safety.

What is being measured

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

  1. False negative rate of vacuum-assisted biopsy

    Absence of invasive and in-situ carcinoma on vacuum-assisted biopsy but presence of invasive or in-situ carcinoma on the surgical specimen.

    Measured: During the surgery

Questions about this trial

What is this clinical trial studying?

A study testing Vacuum-assisted biopsy in people with Vacuum-assisted Biopsy, run by Centre Georges Francois Leclerc at 1 site in France.

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 11 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: under way, not looking for participants, as of the sponsor's last update on 17 Feb 2025. 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 France. 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?

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?

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?

False negative rate of vacuum-assisted biopsy (time frame: During the surgery). 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 17 Feb 2025.
