Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The treatment of these tumors combines breast-conserving surgery and external whole breast irradiation for 6.5 weeks.
A true de-escalation of treatment is taking place with these tumors, both surgically and medically. Surgery therefore now prefers breast-conserving methods in combination with exeresis of the sentinel lymph node only. In the same way, in many international studies, radiotherapy has been evaluating the possibility of reducing both:
* the irradiation volume at the excision site (partial irradiation)
* the duration of this irradiation (accelerated radiotherapy)
Between 2004 and 2007, the CRLC \[Regional Anti-Cancer Center\] evaluated the feasibility and the oncological results of intra-operative partial irradiation via a phase II study in women 65 years of age and older with T1N0M0 hormone-sensitive tumors with a good prognosis.
From 2010 to 2013, the ICM carried out an observational study of these tumors with an excellent prognosis.
In July 2009, the American Society for Radiation Oncology (ASTRO) published a consensus statement with specific recommendations and indications for accelerated partial breast irradiation (APBI).
This APBI technique has been developing in France over the past 5 years within the framework of clinical studies and in compliance with the 2012 recommendations of the French National Cancer Institute. This APBI can be given by 3D external radiotherapy or, as in this study, by intra-operative radiotherapy (IORT) in order to obtain optimal precision and spare as much of the surrounding healthy tissue as possible.
The Investigator therefore propose a cohort study to prospectively analyze the results of this technique applied to the indications strictly defined by the ASTRO.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
1 GROUP
Patient with an Invasive breast cancer with a good prognosis that is accessible to breast-conserving surgery.
The treatment combines extended tumorectomy with axillary dissection (sentinel lymph node) in addition to 20 Gy of per-operative partial irradiation at the tumor Follow up after this treatment will scheduled 10 years
tumorectomy with axillary dissection (sentinel lymph node)
All patients will have local excision of the primary tumor following appropriate clinical work-up. Surgery will be done according to usual local practice with a complete excision of the tumor. The aim of the local excision should be to achieve a minimum free margin of 2 mm whilst maintaining a good cosmetic outcome.
per-operative partial irradiation
20 Gy of per-operative partial irradiation at the tumor site during the surgery
