Adaptive radiotherapy for bladder cancer reduces integral dose despite daily volumetric imaging.
We studied the integral radiation dose in 27 patients who had adaptive radiotherapy for bladder cancer using kilo voltage cone beam CT imaging. Compared to conventional radiotherapy the reduction in margin and choice of best plan of three for the day resulted in a lower total dose in most patients despite daily volumetric imaging.
