Two- to five-millimetre gastrointestinal margins usually limited delivered dose increases but frequently failed to encompass interfraction organ motion.
A 4.5 mm isotropic margin covered most observed small-bowel occupancy despite craniocaudal displacements exceeding 20 mm in some patients.
Four epidermolysis bullosa patients tolerated radiotherapy without greater-than-expected cutaneous toxicity, despite maximum skin dose up to 50.4 Gy.
All patients receiving more than 8 Gy mean dose or 16 Gy maximum dose to the least exposed ovary developed premature ovarian insufficiency.
No radiation myelopathy was observed after target-prioritized intensity modulated radiotherapy for selected nasopharyngeal carcinoma near the spinal cord.
Larger bladder volume was strongly associated with lower planned bladder dose in a static five-fraction prostate radiotherapy analysis.
