Hella Sand looked at rigid v deformable reg for lung #reirradiation. Both performed well, with good inter-centre consistency, but less variation for DIR, especially for cumulative max dose. Results have driven recommendations in the CURE Lung reRT trial #radonc #medphys #ESTRO25

Isak Wahlsted led a national study of dose accumulation for #reirradiation: 8 diverse cases evaluated in all Danish RT centres
Image reg was consistent & high quality; but differences in a/b & tissue recovery gave substantial intercentre variation in cumulative dose #medphys #radonc #ESTRO25

Absolutely no difference in toxicity profiles between 66Gy and dose escalation; even when considering lower grade events or time profiles
(Major caveat: we’re only reporting toxicity up to 6 months at this point - but we’ve not seen any signals in the late toxicity so far either)
