Brief Summary:
This study evaluates the capacity of the NovaGray RILA Breast® test to predict the toxicity linked to radiotherapy and the impact of implant breast reconstruction.

Condition or disease Intervention/treatment Phase
Breast Cancer Capsular Contracture Associated With Breast Implant Device: NovaGray RILA Breast® test Not Applicable

Detailed Description:
Immediate reconstruction after mastectomy may help women with breast cancer to deal with their fear of mastectomy, spare them one or more second surgery and additional hospital stays in case of late breast reconstruction. However, in France, most patients with invasive breast carcinoma and treated with mastectomy are not offered immediate reconstruction. One reason is the need for postoperative radiotherapy for most patients (40 to 70% according to the centers). Indeed, radiotherapy induces side-effects which can alter the cosmetic result of the breast reconstruction as well as the patient's quality of life. Since 1995, a significant correlation is observed between the RILA test (measurement by flux cytometry of the lymphocyte T-CD8 apoptosis induced by radiotherapy) and the risk of occurrence of severe radio-induced breast fibrosis. Such accurate personalized medical care could allow identifying before any treatment high risk of toxicity patients and thus help establishing the therapeutic strategy. Identification of low-risk patients could also allow limiting autologous samplings and thus their associated morbidity.

Arm Intervention/treatment
Experimental: Toxicity test

For all patients, the NovaGray RILA Breast® test will be performed within 15 days of surgery , 12 months after the end of radiotherapy and in the case of neoadjuvant chemotherapy, within 15 days of starting chemotherapy.

The test consists of a blood sample of 2x4 mL

Device: NovaGray RILA Breast® test
The test consists of a blood sample of 2x4 mL. This test will be performed within 15 days of surgery, 12 months after the end of radiotherapy and within 15 days of starting chemotherapy in the case of neoadjuvant chemotherapy.




Primary Outcome Measures :

  3. Precision of the radiosensitivity predictive test [ Time Frame: 12 months ]
    Using the time dependant AUC (AUCt) method

  4. Biological prognostics factors for capsular contracture occurence [ Time Frame: 12 months ]
    Number and type of different biological prognostic factors of capsular contracture occurence

  5. Tumoral prognostics factors for capsular contracture occurence [ Time Frame: 12 months ]
    Number and type of different tumoral prognostic factors of capsular contracture occurence

  6. Success of each surgical strategy in terms of deposit [ Time Frame: 24 months ]
    Number of deposit according to each reconstruction surgery (one or two step)

  7. Cosmetic outcomes measure [ Time Frame: 6, 12, 18 and 24 months ]
    Cosmetic questionnaire : BREAST-Q

  8. Functional outcomes measure [ Time Frame: 6, 12, 18 and 24 months ]
    Functional questionnaire: BREAST-Q

  9. Patient satisfaction measure [ Time Frame: 6, 12, 18 and 24 months ]
    Patient satisfaction questionnaire: BREAST-Q

  10. General quality of life measure [ Time Frame: 6, 12, 18 and 24 months ]
    Quality of life questionnaire: QLQ-C30

  11. Specific quality of life measure for breast cancer patient [ Time Frame: 6, 12, 18 and 24 months ]
    Quality of life questionnaire for breast cancer patient: QLQ-BR23

  12. Stability of the test after chemotherapy [ Time Frame: 12 months ]
    Test score at 12 months after the end of radiotherapy
