About this trial

This clinical study aims to determine if skipping breast and axillary surgery could provide similar control of local and distant disease, with fewer complications and better quality of life, for triple-negative breast cancer patients in complete response after neoadjuvant chemo-immunotherapy.

Patients will be randomised into 2 groups :

* Control arm will receive the standard treatment, including surgery * Experimental arm will receive the standard treatment, except surgery

Eligibility criteria

Qualifiers

Sex and age: Female, aged 18 years or older.

Histological type: Invasive breast carcinoma of no special type (NST).

Estrogen receptor (ER) < 10%,

Progesterone receptor (PR) < 10%,

Disqualifiers

Presence of regional recurrence or metastatic disease at inclusion.

History of thoracic, breast, or regional lymph node irradiation, regardless of indication.

Invasive lobular carcinoma, excluded due to its different response profile and increased risk of multifocal residual disease.

Presence of ductal carcinoma in situ (DCIS) on diagnostic biopsy, or diffuse suspicious microcalcifications on mammography, precluding reliable assessment of complete response.
