Brief Summary:
The purpose of this study is to determine if proton radiation therapy will reduce the amount of heart that is exposed to radiation, thereby decreasing the frequency and/or severity of any cardiac side effects.

Arm Intervention/treatment
Active Comparator: 1
Conventional photon plan
Radiation: Photon
50.4 Gy to the breast/chest wall and peripheral lymph nodes at 1.8 Gy per fraction

Experimental: 2
3D-Proton/Conventional plan or 3D-proton only
Radiation: 3D-Proton/Conventional plan or 3D-proton only
50.4 Cobalt Gray Equivalent/Gray to the breast/chest wall and peripheral lymph nodes at 1.8 Cobalt Gray Equivalent/Gray per fraction

Primary Outcome Measures :
  1. Volume of Heart Receiving ≥ 5 Gray (Gy)/Cobalt Gray Equivalent (CGE) [ Time Frame: 2 weeks prior to starting radiation therapy. ]
    A reduction of 50% in heart volume exposed to radiation doses ≥ 5 Gy/CGE was considered preferred outcome in this study plan.

Secondary Outcome Measures :
  1. Secondary Dosimetric Endpoint [ Time Frame: 2 weeks prior to starting radiation therapy. ]
    Assess improvements in other dosimetry endpoints including lung dose (mean lung dose, V20, V5), heart dose (mean heart, V20, V5), mean dose to the thyroid, mean esophageal dose, D95 coverage for axillary, supraclavicular and internal mammary nodes, maximal spinal cord dose (Dmax) and skin Dmax.

  2. Assessment of Acute Side Effects [ Time Frame: Participants will be assessed weekly during radiation therapy for an expected average of 7 weeks. ]
    Assess acute toxicities including pericarditis, pneumonitis, dermatitis, fatigue, and nausea.

  3. Assessment of Longterm Side Effects and Disease Specific End Points. [ Time Frame: 1 month following completion of treatment, then every 6 months for 5 years, then annually thereafter. ]

    Assess late toxicities including clinical and sub-clinical heart disease, pulmonary fibrosis, soft tissue fibrosis, rib fracture, and secondary malignancies.

    Analyze local control, progression-free survival, and overall survival.

  4. Assessment of Cardiac Function Markers [ Time Frame: after treatment ]
    Assess levels of cardiac function markers Troponin and Brain Naturietic Peptide before and after treatment.
