Beskrivelse
Inclusion Criteria:
- Stage 0 or I breast carcinoma
- 40 years or older
- Post menopausal
- Lumpectomy with clear margins (>2mm)
- Patients with invasive disease must have undergone an axillary staging by axillary dissection (with a minimum of 6 axillary nodes) or sentinal node biopsy
- Gross disease must be unifocal with pathological tumor size 2cm or less
- Target lumpectomy cavity must be clearly marked with surgical clips (the target lumpectomy cavity/whole breast reference volume must be <=30% based on the postoperative imaging)
- Bilateral MRI of the breasts within previous 6 months of radiation therapy (RT) planning
- If patient is eligible based on postoperative imaging, partial breast irradiation (PBI) is judged to be technically deliverable
- Patients with a history of malignancies are eligible if they have stable disease as determined by their attending oncologist
- Patient must have signed the consent form
Exclusion Criteria:
- Men are not eligible
- Patients with Stage II, II, or IV breast cancer
- Pre- or peri-menopausal patients
- Patients with positive lymph nodes
- Patients with suspicious microcalcifications, densities, or palpable abnormalities unless biopsied and found to be benign
- Patients with multifocal, multicentric, or bilateral breast cancer
- Surgical margins that cannot be microscopically assessed or are positive at pathological evaluation
- Patients with a history of breast cancer
- Clear delineation of the extent of the target lumpectomy cavity is not possible
- Breast implants (patients who have had implants removed are eligible)
- Prior breast or thoracic RT for any condition
