Smaller radiation margins may reduce side effects in uterine cancer treatment

This study looked at how much extra tissue around a tumor needs to be treated with radiation after surgery for endometrial or cervical cancer. Using a special technique called online adaptive radiotherapy, doctors adjusted the radiation plan each day to see if they could safely use smaller margins. The goal was to find the smallest margin that still covers the target area while reducing harm to nearby organs like the bladder and rectum. Fifteen patients participated, and the study measured how well the radiation covered the target and how many side effects occurred.
