Brief Summary
Women found to have early stage breast cancer will have their cancer surgically removed followed by radiation treatment to the entire breast, five times per week for several weeks. The radiation treatment prevents the cancer from growing back but creates skin burns. Several studies have showed that it is nor necessary treating the whole breast. The investigators team has pioneered a new therapy realizing the permanent implantation of tiny radioactive seeds into the surgical cavity in a single one hour procedure under light anesthesia. Patients live a normal life while receiving the radiation treatment. The results of a first clinical trial on 67 patients shows that the treatment is well tolerate and efficient. The purpose of the study is to offer the treatment in several places and to increase the cohort of patient to 420 to capture rare complications if any.

Outcome Measures
Primary Outcomes (1)
Serious Adverse Events
Serious Adverse Events (SAE) is an unintended sign, symptom, or syndrome illness that occurs during the period of observation in the clinical study and that is life threatening or result in death. SAE will be coded using the NCI CTC V3.0 scale and corresponds to grade 4 or 5 signs or symptoms.
Initial and then yearly up to 5 years
Secondary Outcomes (9)
Breast cancer local recurrence
Yearly up to 10 years
Regional recurrence
Yearly up to 10 years
Metastases
Yearly up to 10 years
PBSI side effects
After procedure
PBSI side effects
At 2 months
- +4 more secondary outcomes
Study Arms (1)
PBSI
EXPERIMENTALPBSI is a form of accelerated partial breast irradiation involving the insertion of 103-palladium stranded seeds under ultra-sound guidance and light sedation after CT planning in lieu of whole breast adjuvant radiotherapy.
Interventions
Patients are pre-planned using CT simulation. Implant is realised under light sedation and local freezing. Stranded seeds are inserted using a brachytherapy template that is immobilised to the planned target volume using a 'localization' needle. Patients is released the same day and Quality Assurance involves a 2 months post-implant CT

You may not qualify if:
- Previous history of cancer other than curable skin SCC or Tis or T1 cervix
- Patient receiving anti-coagulant that cannot be stopped two weeks prior PBSI
- Autoimmune disorder
- Diabetes insulin-dependant
- Pregnancy
- Breast implants
- Psychiatric or addictive disorder that would preclude attending follow-up
