Clinical Trial Summary

Phi-Bra is a prospective and monocentric pilot study to assess the diagnostic capability of an innovative bra prototype to detect breast cancer, compared to the current standard of care: the mammography.

The Phi-Bra prototype is designed with sensors measuring different parameters simultaneously such as impedance and temperature.

The bra will be tested on patients without breast lump (American College of Radiology (ACR) 1 et 2 Birads classification) and with breast lump (ACR 4b, c ou ACR 5 Birads classification).

The aim of this pilot study is to compare the results obtained by Phi-Bra to the ones obtained by mammography.

The Phi-Bra study is classified as clinical investigation category 4.4 based on the European Union (EU) regulation (DM 2017/745).

Recruitment information / eligibility

• Status: Completed
• Enrollment: 45
• Est. completion date: February 1, 2024
• Est. primary completion date: February 1, 2024
• Accepts healthy volunteers: No
• Gender: Female
• Age group: 18 Years to 75 Years

Eligibility

Inclusion Criteria:

• Age between 18 and 75.

• No breast cancer surgery background

• Bra size : S/M or M/L

Specific criteria for the "no breast lump" cohort:

• Negative mammography result (ACR 1 a 2).

Specific criteria for the "breast lump" cohort:

• Suspicious breast lump discovered during the mammography (ACR 4b ou c ou ACR 5) and for which there is an indication of microbiopsy.

Exclusion Criteria:

• Breast cancer background (surgery or radiotherapy)

• Breast lump classified as ACR 3 ou ACR 4a during the mammography

Related Conditions & MeSH terms

• Breast Neoplasm Female
• Breast Neoplasms

Intervention

Device:
• Phi-Bra prototype measurements
The bra prototype will be placed on the patient's breast. The patient will stay in a half-lying position during 15 min, the time duration of the measurements. Measurements will not be painful. Measurements will only be realized one time during the first and unique visit of the patient.
