  schema:description "A French trial of 470 men compared checking the prostate's position with imaging before every radiotherapy session against checking weekly. Daily imaging lowered rectal side effects and PSA-defined progression, but the main endpoint, recurrence-free survival, did not differ, and overall survival was worse in the daily group."@en ;
