Large target and heart volumes predicted replanning during proton therapy for thoracic cancer
In 180 thoracic proton therapy patients, larger clinical target volume and heart volume independently predicted the need for adaptive replanning.

Weekly monitoring identified week 2 triggers for nodal targets and contralateral parotids, with later week 4 triggers for primary targets.
Mean treated-breast displacement was 1.6 mm, with larger patient-specific changes near treatment completion and during follow-up.
Tumour volume reduction above 40% during radiotherapy was independently associated with improved overall survival in patients with oropharyngeal cancer.
A reusable phantom-based test verified simulation-omitted adaptive workflows on cone-beam computed tomography-guided and magnetic resonance-guided treatment systems.
Patient-specific surface imaging reconstructed breast radiotherapy dose with a 93.8% gamma passing rate and 42-millisecond latency without additional imaging radiation.
Dynamic collimation improved target-region contrast and signal-to-noise ratio while preserving full-field information without increasing the total photon budget.
