About

The time taken to obtain the results of germline mutations in BRCA1 and BRCA2 has become a major issue in adapting the therapeutic management of patients, particularly those with breast cancer.

The time taken to obtain the results of BRCA1/2 tests in routine laboratories with a view to personalised treatment can range from a few weeks to a few months. The waiting time required to obtain results is likely to cause stress and anxiety in cancer patients. The investigators hypothesise that ultra-rapid testing can reduce anxiety about patients' genetic status and improve their mental well-being.

The main objective of this project is to compare the results obtained with an ultra-fast kit developed by O.N.T with those obtained with the current gold standard, NGS sequencing.

• Diagnosis of the disease ≤ 6 months
• The patient must be affiliated to the social security system.

Exclusion criteria

Trial design

150 participants in 2 patient groups

Standard arm

Description:

Analysis carried out using the gold standard with BRCA1/2 results provided on average in 2 months for the theranostic analysis and 3 months for the "standard" analysis + ultrafast BRCA1/2 test (nanopore test) with no communication of results to the patient at 1-2 weeks.

Treatment:

Other: Questionnaires

Experimental arm

Description:

Analysis carried out using the gold standard with BRCA1/2 results provided in an average of 2 months for the theranostic analysis and 3 months for the "standard" analysis + ultra-rapid BRCA1/2 test (nanopore test) with results communicated to the patient in 1-2 weeks. This communication will be accompanied by the necessary explanations to enable the patient to understand that this is a preliminary result and that only the gold standard will constitute a definitive result.
