A prospective trial demonstrating the benefit of personalized selection of breath-hold technique for upper-abdominal radiotherapy using the Active Breathing Co-ordinator (ABC)

Background: For upper abdominal (UA) tumors, our institutional-standard motion reduction method is Expiration Breath Hold (EBH), using Active Breathing Coordinator (ABC)TM. However, an individual patient's breath-hold (BH) reproducibility (RBH) may be improved in Deep Inspiration or Inspiration Breath-Hold (DIBH or IBH). This trial compared the tumor position RBH, stability (SBH), and breath-hold time (TBH) of three BH methods, using ABC, to personalize the selection of technique, by employing a pre-planning screening assessment.
