Immediate Breast Reconstruction's Increasing

Study Overview
=================
Brief Summary
-----------------
Mastectomy in breast cancer is still a way of treatment. Nowadays, the goal is to improve reconstruction's technicals. Immediate Breast Reconstruction (IBR) is one of them, largely used in United States but less in France. However, IGR (Insitut Gustave Roussey) in Paris just wrote a new protocole wich allows more IBR by including more patients. This study aims to compare complications in 2 groups: mastectomies followed by IBR and mastectomies without IBR. The second goal will try to estimate the proportion of eligible's patients to IBR, and to analyse their surgicals and oncologicals risk factors

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Mastectomies with IBR<br>Every women>18 years who underwent mastectomies followed by IBR (prothesis, latissimus dorsi flap, lipofeeling, isolated or combined) for breast cancer in Hôpital de la Croix-Rousse between January 2016 and January 2020 | Other: Comparison of complications between mastectomies with IBR and mastectomies without IBR<br>* Precocious complications (less than 3 months after surgery) are classified with Clavien's classification : hematoma, seroma, stitches, antibiotics, transfusion. Tardive complications (after 3 months until 1 year) are more specifics : hematoma, seroma, tardive infections, asymmetry, removing of implant, breaking up of implant, skin necrosis, capsular contractures, implant loss, chronic pain.<br>Other: To analyze variations of number of patients eligibles to IBR<br>* Including patients with differents classic risk factors : T3, T4, tobacco, diabetes, overweight and obesity, hypertension, age over 70, thoracic irradiation in the past<br>|
