Six-year Experience Routinely Using Moderate Deep Inspiration Breath-hold for the Reduction of Cardiac Dose in Left-sided Breast Irradiation for Patients With Early-stage or Locally Advanced Breast Cancer

Abstract

To date, this series represents the largest experience utilizing mDIBH to reduce cardiac irradiation during left-sided breast cancer treatment. Statistically significant reductions in all heart and lung DVH parameters were achieved with mDIBH over FB plans. mDIBH, for the treatment of left-sided breast cancer, is a proven technique for reducing cardiac dose that may lead to reduced cardiotoxicity and can be routinely integrated into the clinic.
