Ways of dealing with tumours that move as the patient breathes: image the motion, treat only in part of the breathing cycle, hold the breath, or chase the tumour with the beam.
Lung, liver, pancreas and breast targets move by a centimetre or more with breathing. Four-dimensional CT captures the motion so the target volume can include it or be defined at one phase; respiratory gating switches the beam on only during that phase; deep-inspiration breath-hold freezes the anatomy and, in left breast treatment, moves the heart away from the beam; and real-time tracking with fiducial markers or MRI moves the beam or couch with the tumour. Motion management is what makes stereotactic body radiotherapy safe for small mobile targets.
Measure or constrain respiratory motion so the planned dose lands on the target rather than on the tissue it moves through.
Breath-hold for left breast radiotherapy can be delivered without special breathing equipment across ordinary NHS departments, and lowers heart dose in almost everyone selected for it.
The heart benefit of breath-hold is a projection from dose: it rests on the dose-risk relationship measured by Darby and colleagues, not on a trial counting heart attacks in women treated with and without breath-hold.
