Patients undergoing breast conserving surgery for invasive or in situ BC and requiring adjuvant RT are prospectively enrolled -either left-sided cases with or without regional nodal irradiation (RNI), or right-sided cases requiring RNI. Each patient undergoes an additional CT simulation with continuous positive airway pressure (CPAP) (15cm H20) -in free breathing (FB) for right-sided cases and in deep inspiration breath hold (DIBH) for left-sided cases. Left-sided patients unable to perform DIBH are evaluated in FB. Two RT plans (with and without CPAP) are dosimetrically compared. If CPAP reduces mean heart or CLB dose by ≥0.5 Gy, or mean lung dose by ≥1 Gy, treatment is delivered with CPAP. Patient comfort is assessed through surveys.
