DOREMY: reduced-dose 36Gy preop RT holds 5yr LRFS 97.4% in myxoid liposarcoma, supporting de-escalation from 50Gy.
Sarcoma carries the meeting's actionable RT signal: DOREMY's 36Gy preop de-escalation holds local control (5yr LRFS 97.4%) in myxoid liposarcoma, though single-arm with no 50Gy comparator. In prostate, REVELUTION gives a coronary-plaque mechanism for relugolix's cardiac edge over leuprolide (adj diff 68.9mm³) in men on ADT + pelvic RT.
