Wednesday, March 28, 2018 The MAC.23 trial a Phase III Randomized Trial of Hypofractionated Post-Mastectomy Radiation with Breast Reconstruction has been centrally activated About the trial Complexity Level: 2 Eligibility: This study will recruit women and men >=18 post mastectomy due to invasive breast cancer with planned chest wall reconstruction and radiation. Patients will be approached based on the following main criteria: no prior radiation therapy to the chest, neck or axilla, no prior history of ipsilateral breast cancer, no history of prior or concurrent contralateral invasive breast cancer, negative inked histologic margins from mastectomy pathology and Zubrod performance status of 0-1 Objectives: To evaluate whether the reconstruction complication rate at 24 months post radiation is non-inferior with hypofractionation. Secondary objectives include: acute and late radiation complications, based on CTCAE 4.0 toxicity, local and local regional recurrence rate, photographic cosmesis 24 months after radiation, lymphedema at 24 months after radiation, patient satisfaction and well-being at 24 months after radiation (BreastQ,)compare reconstruction complication rates based on reconstruction method and timing of reconstruction, cost and healthcare utilization based on hypofractionation and reconstruction technique MAC.23 trial page
