iodine-125 in granular form is the radioactive element of reference, while palladium-103 may be used for less differentiated tumours with a high doubling time. The doses delivered to the planning target volume are 144 Gy for iodine-125 and 125 Gy for palladium-103. A Gleason score of 7 is still a ‘grey area’, but patients with a Gleason score of 4 + 3 showed no difference in outcome
