The primary rationale for accelerated PMRT is the enhanced convenience for patients, which may result in increased access to PMRT. With data now available documenting the low alpha/beta ratio for breast cancer, the fraction sensitivity of breast cancer can be exploited with higher fraction sizes, resulting in more compressed treatment times. We will deliver a dose of 42.56 Gy to the chest wall/reconstructed breast and regional nodes, in 16 daily fractions, 5 days a week. This fractionation should produce late effects and tumor control comparable to a conventionally fractionated course of 50 Gy to the chest wall and regional lymph nodes delivered in 2 Gy daily fractions
