Upright proton machines are being installed, cleared mainly for the head, neck and upper chest, without any head-to-head comparison with lying down. A proposal: every centre records set-up accuracy, comfort and side effects the same way so the comparison exists.
Upright positioning removes the proton gantry and is now cleared in the United States and Europe (P-Cure 2023, Leo Cancer Care Marie 2025, Mevion S250-FIT 2025), with the S250-FIT limited to sites above the mid-chest when fully seated. OnCo found no randomised or matched comparison of upright and supine treatment. This proposal, which no source makes in these words, is a common registry across upright sites recording daily set-up error, replanning rate, patient-reported comfort and acute toxicity, matched to supine patients at the same centres.
