About this study

Official title: Feasibility Study on the Possibility of Isolation of Volatile Organic Compounds (VOCs) Related to the Olfactory Signature of Breast Cancer

To ascertain the possibilities to isolate the breast cancer olfactive signature

Read the detailed description

Patient recruitment during the first surgery consultation in Curie Institute.

Odor sampling (non-invasive) with an odor-sensing polymer (Sorbstar® polymer developed especially for the trace level analysis), on:

  • The hands, before and after surgical excision of the tumor (friction of the hands)
  • The diseased breast, before and after surgical excision of the tumor (via a compress positioned on the breast for 1 night)
  • The tumor, during the surgical procedure (odor collection over a tumor sample).

Each patient will be her own witness, before and after surgical excision, in an attempt to isolate the chemical signature tracks of breast cancer. The samples after surgery will be made after healing and before implementation of a treatment (chemotherapy and / or radiotherapy).

Being tested
Sorbstar®, Dog Detection

Breast Neoplasms

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sorbstar®Diagnostic test

    Thermodesorption method coupled with full two-dimensional gas chromatography and mass spectrometry

  • Dog DetectionDiagnostic test

    Analysed by the dogs of Curie Institute at the training centers

What is being measured

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

  1. To ascertain the possibilities to isolate the breast cancer olfactive signature

    Isolation of volatile Organic Compounds to breast cancer by a sensitive technique with an odor-sensing polymer (Sorbstar®) on hands. Friction of the hands according to the protocol before and after surgical excision of the tumor. Sorbstar® analyses will be performed with a thermodesorption method coupled with full two-dimensional gas chromatography and mass spectrometry.

    Measured: 18 months

Secondary outcomes (2)
  1. Ascertain breast cancer olfactive signature from the tumor (Isolation of volatile Organic Compounds to tumor breast samples by a sensitive technique with an odor-sensing polymer (Sorbstar®)

    During the surgical procedure an odor-sensing polymer (Sorbstar®) over the tumor is placed. Sorbstar® analyzes will be performed with a thermodesorption method coupled with full two-dimensional gas chromatography and mass spectrometry.

    Measured: 18 months

  2. Ascertain breast cancer detection by the dogs of Curie Institut

    Patients sleep over a night with a compress positioned on the affected breast before and after surgery. The compress will be analyzed by the dogs of Curie Institut (results cancer/not cancer).

    Measured: 18 months

Questions about this trial

What is this clinical trial studying?

A study testing Sorbstar® and Dog Detection in people with Breast Cancer and Surgery, run by Institut Curie 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 6 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: finished, as of the sponsor's last update on 22 Sep 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?

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?

To ascertain the possibilities to isolate the breast cancer olfactive signature (time frame: 18 months). 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 NCT04541537, 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 22 Sep 2025.
