Study Arms (1)
Accelerated Partial Breast Irradiation
EXPERIMENTALAccelerated partial breast irradiation using proton beam scanning will consist of; * 5 daily treatments using custom prone patient immobilization, contrast-enhanced CT planning, and daily image guidance * Radiation therapy may be delivered with photons if proton treatments cannot be delivered * Dose will be prescribed such that the gross tumor (GTV) receives the prescription dose per institutional policy and standard of care * Daily target localization will also be confirmed using AlignRTTM
Interventions
Proton radiation
AlignRTTM uses infrared imaging to capture the 3D data of the patient's position to ensure accuracy of treatment delivery
Eligibility Criteria
You may qualify if:
- Age at least 40 years
- Core biopsy proven estrogen negative (\< 1%), progesterone negative (\< 1%), and HER2-neu negative (+1 by immunohistochemistry and/or FISH ratio \< 2.0) invasive breast cancer
- Unicentric AJCC 7th edition T1N0M0 tumor measuring no greater than 2.0 cm in longest dimension on initial imaging with either breast MRI and/or mammogram
- ECOG Performance status \< 1
- No prior treatment for this diagnosis of cancer
- No prior radiation to the ipsilateral breast, a history of contralateral breast radiation is permitted
- No clinical or radiographic evidence of malignant regional adenopathy
- No contraindication to breast conserving surgery, sentinel lymph node biopsy, or radiation therapy
- Ability to understand and willingness to sign a written informed consent document.
- Pregnant females are excluded. Female subjects of childbearing potential must indicate to their physician that there is not a possibility of being pregnant at the time of enrollment or have a negative pregnancy test prior to initiation of radiation therapy
You may not qualify if:
- Multicentric breast cancer, defined as discontiguous tumors separated by at least 5 cm of uninvolved tissue or discontiguous tumors that are located within separate breast quadrants either clinical or mammographically.
- Multifocal breast cancer, defined as discontiguous discrete foci of invasive carcinoma, separated by uninvolved intervening tissue, but within an overall span of 5 cm, or within the same breast quadrant.
- Tumor \> 2.0 cm, nodal involvement, or metastatic involvement
- Patients with either diffuse (\>1 quadrant or \> 5 cm) suspicious microcalcifications on mammogram or diffuse non-mass-like enhancement on MRI
- History of ipsilateral cosmetic or reconstructive breast surgery
- Patients with a pacemaker or defibrillator
- Any contraindication to MRI including but not limited to the presence of a pacemaker/defibrillator or other implanted ferromagnetic device or an inability to lie prone
- Pregnant or lactating women
- Medical condition including but not limited to ongoing or active infection or connective tissue disease (e.g. systemic sclerosis or other collagen vascular diseases) that would, in the opinion of the treating physician, make this protocol unreasonably hazardous to the patient.
- Psychiatric illness/social situation that would limit ability to provide informed consent
