Use of intensity modulated radiation therapy to reduce acute and chronic toxicities of breast cancer patients treated with traditional and accelerated whole breast irradiation

This analysis confirms previous data which have demonstrated that RT with IMRT is associated with reduced toxicities compared with conventional techniques. In larger breasted women, with the exception of acute skin reactions, I-AWBI showed comparable rates of toxicities compared with I-WBI. These data support the use of IMRT to expand the role of AWBI and the currently accruing Radiation Therapy Oncology Group 1005 trial.
